PROBLEM

Show/hide table

The following issues may be noticed on certain 770G and 772G Off-Highway Trucks:
1. The brake oil cooler tube on the Left hand side may rub with hoist cylinder during machine operation.
2. The Hose line connected to the Brake Valve may rub with the Dual Slope body during machine operation due to less clearance between the dump body and hose line.
3. Current routing of the 309-1362 Lines Group-Oil Cooler may cause the 362-2985 Hose to rub with the Hoist Cylinder.
