Truck parts HD90149320000
Technical Notes
1. Installation Precautions
Pre-Installation Inspection:
Before fitting the assembly, check for any visible damage. Make sure all attached parts match OE specs. Clean the powertrain's mounting area too-wipe off oil, rust, or dirt so there's no weird noise or vibration after installation.
Torque Specification Compliance:
Use a calibrated torque wrench to tighten the mounting bolts. Check the vehicle's service manual for the right torque value. If you tighten too much, you might damage the housing; too little, and bolts could come loose when the vehicle's running.
Lubrication Requirement:
Before using the assembly, fill the differential housing with hypoid gear oil that meets API GL-5 standard. Get the oil level right to the specified mark-if it's too low, gears can overheat from not enough lubrication.
2. Maintenance Guidelines
Regular Oil Change:
Change the gear oil every 60,000 km or 24 months, whichever happens first. If the vehicle is used in tough conditions, change it sooner-every 40,000 km or 18 months. Drain all the old oil and clean the oil drain plug so no residue mixes with the new oil.
Routine Inspection:
Every 15,000 km, check around the housing seals and fasteners for oil leaks. If there's a leak, replace the seal rings right away. Also, listen for odd noises when driving-those could mean gears are worn or there's not enough lubrication, so you'll need to take the assembly apart and check it soon.
3. Safety & Operational Warnings
Avoid Overloading:
Don't go over the maximum load capacity set by the vehicle manufacturer. Overloading can break gear teeth or bend the housing, and that'll make the whole differential system stop working.
Proper Handling During Disassembly:
When taking the assembly off for repairs, use a lifting tool to hold its weight-this keeps you from getting hurt and prevents damage to the part. Don't hit the gears or housing with hard tools.
Post-Repair Testing:
After installing or repairing the assembly, take the vehicle for a slow test drive (5-10 km). Don't accelerate suddenly or brake hard during this test-let the gears wear in gently.
