Transmission Gearbox Housing ISUZU NKR NPR 4HG1 MYY5T 8972370990

This is a high-quality aftermarket Transmission Housing (gearbox casing), OE reference 8972370990 (Isuzu). Manufactured to original specifications with precision-machined bores, bearing seats, and sealing surfaces, it is a direct replacement for the original gearbox case — the ideal solution for transmission overhaul, case replacement after cracks or impact damage, and drivetrain rebuilding. Available for wholesale with bulk pricing, stable supply, and OEM/ODM customization.

Core Advantages

1. Matching OE reference with identical casting geometry and mounting points — direct replacement, no modification.

2. Machined bores and bearing seats ensure correct gear mesh, reducing noise, wear, and premature failure.

3. Properly machined sealing surfaces work with new gaskets and seals for reliable oil retention.

Application Scenarios

Transmission rebuild shops: Replacing damaged or worn housings during complete gearbox overhauls.

Fleet maintenance: High-mileage commercial fleets replacing cracked housings on a repair schedule.

Aftermarket parts (IAM): A core line item for transmission and driveline parts distributors.

Core exchange programs: Supplying housings to rebuilders and exchange-transmission programs.

Usage & Installation Guide

Pre-installation check: Verify the OE number, Isuzu model, and transmission code; inspect the bell housing, clutch, and mating surfaces.

Transfer internals: Move gears, shafts, bearings, and synchronizers from the old case into the new housing per the factory service manual — keep components in correct order and orientation.

Sealing: Install new gaskets and oil seals; apply sealant to the specified surfaces.

Assembly & torque: Reassemble the gearbox, tightening fasteners to the specified torque in the correct sequence.

Fill & test: Refill with the correct grade and volume of transmission oil; test all gears before returning the vehicle to service.
