REPAIR INSTRUCTIONS 17. Lubricate all synchronizer friction and reaction discs, using the recommended lubricant.
Before and during installation, make sure to lubricate all synchronizer assembly friction and reaction discs and associated parts (gear and gear hub) using the recommended lubricant. This prevents premature wear to individual parts of the assembly during initial transmission start-up. 18. Install the first internal-toothed friction disc into the Lo-range gear, and then install the first external-toothed reaction disc onto the friction disc just installed. 376
19. Continue alternately installing the remaining friction and steel reaction discs until four of each have been installed. Make sure to lubricate each friction and reaction disc with specified gear oil during installation. The last disc installed should be an external-toothed steel reaction disc. 20. Align the tangs (external teeth) of the steel reaction discs and then install the synchronizer assembly over the rear mainshaft (output shaft). Engage the slots of the synchronizer clutch housing with the tangs of all four reaction discs.
Make sure that the synchronizer assembly is installed with the “R” markings on the clutch and pins, facing the rear of the mainshaft against the discs just installed.
Rotating the synchronizer assembly back and forth during installation helps the assembly to align with the external teeth of the steel reaction discs. 378
