ISUZU 8-97204108-0 8972041080 Flywheel Housing For 100P-T 4JB1 Truck
Product Description
Function :
A precision-machined cast iron housing that serves as a structural backbone, connecting the engine block to the transmission bell housing. It aligns the crankshaft with the transmission input shaft, houses the rear crankshaft oil seal, and provides mounting for the starter motor in Isuzu 4JB1 engines.
Product Description (Detailed):
The Flywheel Housing Assembly (OEM Numbers: 8-97204108-0 / 8972041080) is a premium-quality, direct replacement structural component engineered specifically for the ISUZU 100P-T and 100P light trucks, which are powered by the legendary 4JB1 2.8L turbo diesel engine. As a critical interface, this casting precisely aligns the engine and transmission, ensuring the transmission’s input shaft enters the crankshaft’s pilot bearing without binding. This precise alignment is crucial for preventing premature wear on the clutch disc, transmission bearings, and input shaft seal.
Manufactured to meet or exceed original equipment (OE) specifications, this housing is constructed from high-strength cast iron, ensuring resistance to distortion under heavy torsional loads from the engine and chassis. The part includes precisely machined mounting surfaces for the engine block, the transmission bellhousing, and the starter motor. Additionally, it features a machined bore for the rear crankshaft oil seal (CR seal), which prevents engine oil leakage and protects the clutch assembly from contamination.
A damaged or misaligned flywheel housing will lead to severe drivability issues. Symptoms include persistent engine oil leaks from the rear main seal area (even after replacing the seal), difficulty starting the engine (the starter may fail to engage correctly due to a misaligned nose housing), excessive driveline vibration, and premature failure of transmission input shaft bearings. The casting can also become cracked due to over-torquing of transmission mounting bolts or collision damage.
Note: Professional installation by a qualified heavy-duty mechanic is mandatory. A new rear main seal (crankshaft oil seal) and housing gasket are typically required for this installation and are sold separately.

*Note: This housing is designed for the 4‑cylinder 4J engine family (4JA1, 4JB1, 4JB1-T). It is not compatible with 6‑cylinder engines (6BG1, 6BD1, 6HH1, 6HK1, 6WG1) or later common‑rail engines (4JJ1, 4HK1, 4JK1), which use a different flywheel housing bolt pattern.*
Why Replace the Flywheel Housing – Real Fleet Data
The ISUZU 100P platform is a global workhorse, trusted in urban delivery, construction support, and municipal fleets. On high‑mileage vehicles (300,000+ km / 186,000+ miles), the flywheel housing is a structural component that can be damaged or wear in several ways. A key fact is that the flywheel housing incorporates the mount for the rear crankshaft oil seal. When this housing is cracked or the sealing surface is damaged, the oil seal cannot function, leading to persistent leaks—a problem often misdiagnosed as a failed seal. Replacing the housing resolves the root cause.
Symptoms of Flywheel Housing Damage or Failure:
| Symptom | Likely Cause | Action |
|---|---|---|
| Engine oil leaks at the rear / between engine and transmission | Cracked housing or damaged sealing surface for the rear main seal — oil bypasses the seal and leaks out | Replace flywheel housing; inspect crankshaft flange for wear |
| Transmission input shaft bearing wear / noise | Housing misalignment (warped or damaged) — input shaft not concentric with crankshaft | Replace housing; verify alignment with dial indicator |
| Difficulty starting (starter motor grinding or failing to engage) | Cracked or damaged starter mounting boss — starter pinion misaligned with flywheel ring gear | Immediate housing replacement; inspect flywheel ring gear for damage |
| Driveline vibration / shudder on acceleration | Cracked or warped housing causing driveline misalignment | Replace housing; verify engine and transmission mounts |
| Cracked housing / structural failure | Over-torqued transmission bolts or collision damage | Immediate replacement — structural integrity compromised |
| Flywheel housing gasket failure / oil seepage | Warped housing flange or damaged gasket surface | Replace housing; use new gasket and proper torque sequence |
| Crankshaft rear main seal repeatedly fails | Housing bore is scored or out‑of‑round — cannot seal correctly | Replace housing; inspect crankshaft flange surface |
Note: If the engine has suffered a rear main seal failure, the flywheel housing bore should be inspected for scoring or damage. A damaged housing bore will cause repeated seal failure, even if a new, high‑quality seal is installed.
Features & Advantages
OE Quality: Manufactured to strict ISUZU OEM dimensional and material standards for a perfect, direct‑fit replacement — no modifications, adapter brackets or custom machining required. All critical dimensions (crankshaft pilot bore, engine block mounting face, transmission mounting face) are verified against OE blueprints using CMM equipment.
Critical Alignment Component: The flywheel housing is the structural link between the engine and the transmission. It ensures that the crankshaft centreline and the transmission input shaft centreline are perfectly aligned. Misalignment of even 0.5 mm will cause rapid wear of the transmission input shaft bearing, pilot bearing, and clutch disc splines.
High‑Strength Cast Iron Construction (FC200): Manufactured from high‑grade cast iron (FC200), heat‑treated and stress‑relieved to resist warping, cracking, and deformation under heavy torsional loads. The casting is ribbed at stress points to increase structural rigidity, ensuring long‑term reliability in demanding commercial applications.
Precision‑Machined Sealing Surfaces: The housing features a precision‑machined bore for the rear crankshaft oil seal (CR seal). The surface is machined to a fine finish (Ra ≤ 1.6 μm) to ensure a leak‑proof seal, preventing engine oil from contaminating the clutch assembly.
Integrated Starter Motor Mounting: The housing includes a precision‑located starter motor mounting flange. The dowel pin holes and bolt hole spacing are machined to exacting tolerances, ensuring the starter pinion engages the flywheel ring gear correctly — eliminating grinding and premature starter failure.
Precision Dowel Pins for Alignment: Factory‑installed hollow dowel pins locate the housing precisely on the engine block, preventing misalignment during assembly and ensuring repeatable positioning even after multiple transmission removals.
Restores Driveline Integrity: Replaces a cracked or warped housing, eliminating oil leaks, driveline vibration, starter misalignment, and transmission input shaft bearing failure — returns factory‑fresh engine-to-transmission alignment.
Direct Replacement: Simple bolt‑on installation (professional mechanic recommended) — matches factory mounting points, dowel pin locations, and bolt hole patterns with no modifications required.
Wide Application Coverage: Fits ISUZU 100P, 100P-T, NKR55, NKR58, NKR59, NHR, ELF 250/350, and compatible JMC / Qingling chassis with 4JB1 engine.
12‑Month Warranty: Backed by manufacturer batch traceability and a comprehensive 12‑month warranty against material and manufacturing defects.
ISO 9001:2015 / IATF 16949 Certified: Manufacturing facility meets international automotive quality management standards, ensuring consistent, traceable and reliable output for wholesale commercial fleets.
Wholesale Advantage: Perfect for heavy‑truck parts distributors, workshop chains, fleet operators, and international exporters — sold individually or in bulk case packs (5, 10, 20, 50 units).
Packaging & Supply
Individual Packaging: Each flywheel housing is anti‑corrosion oil‑coated, individually sealed in a moisture‑barrier VCI bag and boxed with OE‑style part labeling.
Wholesale / Bulk Orders: Available for heavy‑truck parts distributors, engine rebuilders, workshop chains, fleet operators, and international exporters — sold in case packs (5, 10, 20, 50 units); pallet pricing available for volume orders.
Customization: Neutral or private‑label retail packaging (including custom barcode labels) is available for volume wholesale orders (minimum order quantity applies). Discuss your branding requirements with our sales team.
Fast Shipping: Ready stock for immediate dispatch worldwide via express courier (DHL, FedEx, UPS) for urgent repairs, or economical sea freight from central logistics hubs (Guangzhou, Singapore, Rotterdam, Los Angeles).
Wholesale Support: Long‑term supply agreements, tiered commercial pricing and drop‑shipping options available for approved distributors. Contact our ISUZU engine parts department to set up a wholesale account today.
