Clutch Release Bearing Seat ISUZU TFR
,OEM Clutch Release Carrier 8943282380
,Clutch Release Seat 4JA1 4ZD1 Engine
The Clutch Release Bearing Seat with OEM numbers 8-94328238-CHM / 8-94328238-0 / 8943282380 is a verified direct-fit replacement for ISUZU TFR and TFS pickup trucks equipped with the 4JA1 and 4ZD1 diesel engines (1993–2003). This component is a critical part of the clutch release system, responsible for housing and guiding the release bearing as it moves along the transmission input shaft bearing cover to disengage the clutch.
How It Works: The release bearing seat (carrier) is mounted on the transmission input shaft bearing retainer and holds the release bearing. When the clutch pedal is depressed, the release fork pushes the bearing seat (and bearing) forward against the diaphragm spring of the pressure plate, disengaging the clutch. The seat must slide smoothly along the retainer to ensure proper clutch engagement and disengagement.
- Real Shop Test Data: Seat sliding surface hardness verified at HRC 45–50 — confirmed on 50 units by hardness tester.
- Proven Durability: Rated for 100,000+ km under normal clutch operation — based on fleet maintenance records from ISUZU TFR operators.
- Installation Success Rate: 98% direct fitment — confirmed across 300+ clutch repair orders in workshop records.
- OEM Cross-Reference Verified: Replaces 8-94328238-CHM, 8-94328238-0, 8-94328238-NSKK, 8943282380. Bearing companion part: 48TK3201 / 48TKB3201.
Replace the release bearing seat if you observe any of the following:
- Clutch pedal feels spongy or fails to disengage fully
- Grinding or difficulty shifting gears, especially into first or reverse
- Squealing or chirping noise when the clutch pedal is depressed
- Release bearing seat cracked, worn, or distorted
- Clutch slips under acceleration despite correct pedal adjustment

⚠️ Important Fitment Notes:
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily designed for ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs. "long" pushrod variants exist within the MC828264 family.
- Always provide your VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Dimensional Accuracy | CMM (Coordinate Measuring Machine) inspection |
| Surface Hardness | Rockwell hardness test (HRC 45–50 target) |
| Sliding Surface Finish | Roughness tester (Ra ≤ 1.6 μm) |
| Material Composition | Spectrometer analysis |
| Mounting Fit | Go/No-Go gauge verification |
| Visual Inspection | 100% unit inspection for cracks, porosity, and machining defects |
⚠️ IMPORTANT: Clutch replacement requires transmission removal. Professional installation is strongly recommended. Always inspect the release bearing, clutch fork, and input shaft retainer for wear before reinstalling.
- Disconnect the battery and remove the transmission per the manufacturer's procedure.
- Remove the old release bearing and seat from the input shaft retainer.
- Clean the retainer surface and inspect for wear, scoring, or damage.
- Lubricate the new seat sliding surface with high-temperature clutch grease (thin film only).
- Install the new seat and bearing assembly onto the retainer; ensure smooth sliding movement.
- Reinstall the release fork and verify proper engagement with the seat.
- Reinstall the transmission and bleed the clutch hydraulic system if equipped.
- Test clutch operation: the pedal should feel firm, and gears should engage smoothly without grinding.
- Inspect clutch release components at every clutch service interval or if pedal feel changes.
- Replace the seat if worn, cracked, or if the bearing does not slide smoothly.
- Avoid riding the clutch pedal, which accelerates seat and bearing wear.
- Individual protective bag + neutral carton (custom packaging available)
- Suitable for: auto parts wholesalers, transmission repair shops, fleet maintenance centers, and ISUZU pickup specialists
