Belt Side Bearing for TSCAR-8H Concrete Scarifier (810030): Fitment, Replacement, and Compatibility
Share
A TSCAR-8H that is torn down for the wrong part is just expensive weight on the truck. If your crew is trying to get back to coating removal, slab prep, trip-hazard repair, or high-spot grinding, the first job is not buying a bearing. It is confirming the failed location.
At Concrete Tools Direct, we treat the Belt Side Bearing for TSCAR-8H Concrete Scarifier (810030), SKU TSCAR-8H-BRG30, as a fitment part first. It is tied to the TSCAR-8H platform, including the 8" Gas Concrete Scarifier Planer Grinder with 5.5 HP Honda Engine & Drum. Before you order the belt side bearing for tscar 8h concrete scarifier 810030, confirm the machine model, confirm the belt-side bearing location, and make sure you are not actually looking at a belt, wheel, or opposite-side bearing problem.
Fitment Answer Up Front
Part 810030 is the belt-side bearing for the TSCAR-8H concrete scarifier when that specific bearing location has failed. If the belt is worn, the other bearing is the failed part, or the front wheels are causing the handling issue, 810030 is not the fix. That may sound obvious in the shop, but on a dusty scarifier with guards pulled and parts on the bench, close-enough ordering gets expensive fast.
Key Takeaways
- 810030 belongs at the belt-side bearing position on the TSCAR-8H platform.
- Confirm the parent machine before ordering. The part is associated with the TSCAR-8H scarifier machine.
- Do not treat 810030 as a universal shop bearing. Match it to the machine model and the failed bearing location.
- Check the belt, the opposite bearing, front wheels, and nearby hardware while the machine is open.
- If the failure is not at the belt-side bearing, order the part that matches the actual failed component.
What It Is
This is the replacement bearing used at the belt side of the TSCAR-8H concrete scarifier platform. It is not the cutter drum, not the drive belt, not a wheel set, and not an engine control part. For a contractor looking for a replacement bearing for scarifier repair, 810030 only fits the TSCAR-8H belt-side bearing location.
The TSCAR-8H is used on concrete work where the machine has to keep turning under dirty, abrasive conditions: coating removal, surface preparation, overlay profiling, high-spot leveling, traffic-line removal, and sidewalk trip-hazard repair. The bearing is one service part in that system. Its value is not magic. It simply needs to be the right bearing, in the right location, on the right machine.
How It Works
A bearing supports rotation. On the belt side of a scarifier, that support helps the connected assembly turn without dragging against its mount. When the bearing is healthy, the drive side can run more cleanly. When it is worn, rough, loose, or damaged, the machine may feel wrong even if the belt itself is still present and intact.
The belt and the bearing sit close enough to confuse the repair if you do not slow down and trace the failure. The belt is the flexible drive component. The belt-side bearing is the support component. Replacing the belt will not fix a rough bearing, and replacing the bearing will not fix a belt that is cracked, stretched, or damaged. Concrete dust loves hiding the evidence, so clean enough of the area to see what is actually going on.
Field check: if the belt cover is already off, rotate the belt-side assembly by hand and feel for grit, notchiness, rough spin, or side play before blaming the belt. Heat, grinding noise, wobble, belt-side looseness, and visible movement at the bearing location all point you toward a bearing inspection. A belt that is visibly damaged, a front end that rolls poorly, or a start/stop control issue points somewhere else.
When To Use It
Use 810030 when your TSCAR-8H has a confirmed failure at the belt-side bearing location. The usual clues are rough rotation, grinding noise, looseness, side play, heat around the bearing area, wobble, or drag that remains after the belt path has been checked. None of those symptoms is a final diagnosis by itself, but they are enough to make the belt-side bearing worth a close look.
| What you see or feel | Likely direction | What to verify before ordering |
|---|---|---|
| Rough spin, notchiness, grinding, or heat at the belt-side bearing | Inspect 810030 location | Machine model, part number, and bearing position |
| Visible belt wear, cracking, glazing, or belt damage | Inspect the belt | Whether the bearing is also loose or rough |
| Looseness or noise at the other bearing location | Check the other bearing part | Parts diagram location and part number |
| Poor rolling, front-end drag, or uneven front support | Inspect front wheels | Wheel condition and hardware |
The part makes sense when the machine is otherwise worth keeping in service. If the scarifier is still earning its place on coating removal, slab prep, overlay prep, texturing, high-spot grinding, or trip-hazard work, replacing the correct failed support part is usually better than letting a small repair become a schedule problem.
Types Or Options
For this repair, the “option” is not picking a bearing that looks close on the bench. The real choice is identifying whether the failed part is the belt-side bearing, the belt, the other bearing, or the front wheel set. Each one can affect how the scarifier feels, but they do different jobs.
| Part path | Use it when | Do not use it for |
|---|---|---|
| 810030 belt-side bearing | The belt-side bearing support is the failed location | Worn belt, opposite bearing failure, or wheel wear |
| 810035 bearing | The other bearing location is called out | Belt-side bearing repair |
| 810009 pulley belt | The belt is worn, damaged, or being replaced during maintenance | Bearing support damage |
| 810040 front wheels | The issue is front support, rolling action, or machine handling | Drive-side bearing problems |
If you are not sure which part failed, do not order by symptom alone. A scarifier can rattle, drag, or feel rough for more than one reason. Follow the parts diagram and the actual failed location.
Specs Or Features Explained
The most important “spec” here is fitment. 810030 is identified for the belt-side bearing position on the TSCAR-8H platform. CTD lists it as a new, manual, professional-level replacement part with a medium-duty rating. Those details help confirm what lane the part belongs in, but they do not replace the model tag or the parts diagram.
| Detail | What it means in the shop |
|---|---|
| Part number 810030 | Use this to match the belt-side bearing callout in the TSCAR-8H parts information. |
| Belt-side location | Confirms the part is for the support point near the belt side, not the belt itself. |
| TSCAR-8H platform | Confirms the machine family before you compare nearby wear parts. |
| Manual replacement part | This is a service component, not a powered attachment or cutting accessory. |
Do not ask this bearing to answer machine questions it does not control. Production rate, cutting depth, drum tooling, dust handling, surface profile, and pass planning belong to the scarifier setup and the job conditions. This part answers a narrower question: is the failed component the 810030 belt-side bearing on a TSCAR-8H?
Selection Guidance
Use TSCAR-8H part identification from the machine tag and parts diagram before ordering. Shop habit: take a quick phone photo of the model tag and the failed bearing location before you buy, especially when multiple TSCAR-8H wear parts are on the bench.
| Pre-purchase check | What you are confirming |
|---|---|
| Machine model tag | The scarifier is a TSCAR-8H platform. |
| Part number | The diagram or parts callout points to 810030. |
| Belt-side location | The failed bearing is on the belt side, not the opposite bearing position. |
| Belt condition | The belt is not the primary failed part. |
| Opposite bearing | You are not mistaking the other bearing location for 810030. |
| Front wheels and hardware | Handling or rolling complaints are not being blamed on the wrong component. |
The rule is simple: match the machine, match the part number, match the location. If all three line up, you are in the right lane. If one of them does not, stop and sort that out before ordering.
Application Guidance
Treat this as a focused scarifier maintenance part, not a full rebuild plan. The bearing matters because a TSCAR-8H often works in rough conditions: removing old coatings from concrete, prepping a slab for coatings, profiling for overlays, texturing concrete for slip resistance, leveling high spots, and fixing sidewalk trip hazards. Dust, vibration, and abrasive debris make inspection harder, so clean the area enough to see the bearing, belt, fasteners, and surrounding support points.
This page is not a step-by-step repair procedure. Follow the manufacturer’s manual and parts diagram before removing guards, loosening drive components, or installing replacement parts. Our role here is to help you confirm fitment and avoid ordering the wrong component. The repair work still needs to be handled according to the machine instructions and normal jobsite safety practices.
If the machine is already open, inspect nearby parts before you button it back up. That does not mean replacing every part in sight. It means catching obvious belt damage, loose hardware, a rough opposite bearing, or front wheel wear while your crew already has the scarifier on the bench.
Compatibility Notes
Keep 810030 grouped with concrete scarifier replacement parts for the TSCAR-8H, not universal shop bearings. The verified platform is the TSCAR-8H, including the 8-inch gas scarifier sold by CTD under that machine family. Do not size the bearing by eye or assume a similar-looking scarifier uses the same part.
Compatibility is also about location. The belt-side bearing is not interchangeable with the drive belt, front wheels, or the other bearing just because those parts live near the same work zone on the machine. If the parts diagram points to a different callout, follow the diagram. If your machine marking does not confirm TSCAR-8H, verify before ordering.
This bearing does not determine wet or dry operation, dust collection setup, cutter choice, cutting depth, or surface profile. Confirm those items against the parent machine information, the manual, and the requirements of the slab you are working on.
Common Mistakes
The most common mistake is ordering by name instead of location. “Bearing” is not enough. On this scarifier, you need the correct bearing callout, on the correct side, for the correct machine. A little checking beats finding out the wrong part is on the bench when the crew is ready to load out.
| Mistake | Why it causes trouble | Better move |
|---|---|---|
| Skipping the machine model check | A similar-looking scarifier may not use the same part. | Confirm the TSCAR-8H model marking first. |
| Confusing the belt with the belt-side bearing | The symptom may stay after the wrong part is replaced. | Inspect belt condition and bearing feel separately. |
| Assuming both bearing locations use the same part | Different locations can have different part numbers. | Match 810030 or 810035 to the diagram. |
| Blaming a bearing for front-end handling issues | Wheel wear and front support problems can feel like machine drag. | Inspect the front wheels as their own repair path. |
| Ignoring loose or missing hardware | A good replacement part cannot fix poor assembly condition. | Check surrounding fasteners while the machine is open. |
Product Recommendations
If you are maintaining this parts family, start with the parent machine. The 8" Gas Concrete Scarifier Planer Grinder with 5.5 HP Honda Engine & Drum, SKU TSCAR-8H + TSCAR6TCC, is the featured TSCAR-8H platform at CTD. It is a light-duty, professional, gas-powered scarifier with a Honda GX160 engine, 5.5 HP (4.0 kW) power, 135 lb weight, 8 in working width, listed 350–500 sq. ft. per hour productivity, 1/8 in cutting depth per pass, and a 1-year warranty. Its listed applications include removing traffic lines from concrete, leveling uneven slabs, sidewalk trip-hazard removal, prepping concrete floors for new coatings, removing old coatings from concrete, prepping for concrete overlays, grinding down high spots in concrete, warehouse floor surface prep, and driveway surface prep.
For the specific repair covered on this page, choose the Belt Side Bearing for TSCAR-8H Concrete Scarifier (810030) only when the belt-side bearing is the confirmed failed location. CTD lists it as SKU/model TSCAR-8H-BRG30, a new, medium-duty, professional-level, manual replacement part for repairing a TSCAR-8H used in concrete surface preparation and related scarifying work.
If inspection points elsewhere, compare the neighboring parts instead: the Pulley Belt for TSCAR-8H Concrete Scarifier (810009) for belt wear or belt maintenance, the Bearing for TSCAR8H Concrete Scarifier (810035) for the separate bearing location, and the Front Wheels for TSCAR8H Concrete Scarifier (810040) when the issue is front support, rolling action, or machine handling.
Related Accessories Or Consumables
While the machine is open, inspect nearby scarifier wear parts such as the belt, opposite bearing, wheels, and fasteners. They are not substitutes for 810030, but they can create symptoms that feel close enough to send you down the wrong repair path.
Use the belt part when the drive belt is worn, damaged, or being serviced. Use the other bearing part when the failed location is not the belt side. Use the front wheel set when the scarifier’s front support or rolling action is the problem. If the complaint is electrical start/stop behavior rather than mechanical roughness, do not chase a bearing first.

Related Articles
For the parent platform reference, start with the TSCAR-8H scarifier machine. From there, compare the belt, the other bearing, and the front wheels if your inspection points away from 810030. Keeping the repair tied to the machine layout is the cleanest way to avoid a parts order built on guesswork.
Faqs
Is 810030 the correct bearing for my TSCAR-8H?
Yes, if your scarifier is a TSCAR-8H and the failed location is the belt-side bearing called out as 810030. Confirm both the model and the part location before ordering.
How do I tell whether the belt-side bearing failed?
Look for rough spin, grinding noise, heat, side play, wobble, looseness at the belt-side support, or drag that is not explained by belt condition. Those signs point to a bearing inspection, but the parts diagram and actual failed location should make the final call.
How is 810030 different from the pulley belt?
810030 is the belt-side bearing. The pulley belt is the flexible drive part. They sit near each other, but they do different jobs and are not interchangeable fixes.
Is 810030 the same as the 810035 bearing?
No. Treat them as separate bearing locations unless the machine’s verified parts information says otherwise. If the diagram calls out 810035, do not assume 810030 will solve it.
Should I replace the belt at the same time?
Only if inspection shows the belt is worn, damaged, or due for service. Do not replace parts just because they are nearby, but do inspect them while access is good.
Can CTD confirm fitment from my machine information?
We can help you work through the fitment question if you provide the machine model, part number, and failed location. A photo of the model tag and the belt-side area usually makes that conversation more useful.
Next Steps
Quick answer before you buy: confirm the scarifier is the TSCAR-8H, confirm the failed location is the belt-side bearing, and confirm the part number is 810030. If all three line up, order the Belt Side Bearing for TSCAR-8H Concrete Scarifier (810030). If the belt, opposite bearing, or front wheels are the real issue, follow that part path instead.
If you are still not sure, send CTD the machine model, the part number you are seeing, and a clear photo of the failed area before you order. We would rather help you match the part once than watch your crew lose another afternoon to the wrong box on the bench.
