Range Synchronizer
Special Instructions
During disassembly, place the Synchronizer Assembly on a clean, flat surface. Cover the Synchronizer Assembly with a shop rag to prevent losing the
three (3) springs under pressure from the HI Range Synchronizer Pin locations.
Perform assembly on a clean flat surface slightly lower than your waist. Pins on the LO range synchronizer must line up with the chamfered holes on the sliding clutch bottom. When compressing the HI range synchronizer springs, cover with a shop rag. This will prevent the springs from leaving the area if compression is not achieved.

Range Synchronizer Disassembly
Place the low range synchronizer on a bench with the larger ring facing down, (place a shop towel over the assembly to avoid losing any springs).
Grab both sides of the HI Range Synchronizer and pull.
Remove the sliding clutch from the pins of the synchronizer ring.
Range Synchronizer Assembly
Install the Sliding Clutch on the blocker pins with the recessed side up.
Install the three springs into the bores of the HI range synchronizer ring.
Place the HI range synchronizer ring over the blocker pins of the LO range synchronizer, seating the springs against the pins.
Cover with shop rag, and apply downward pressure to the HI range synchronizer ring while twisting counterclockwise to copress the springs and fully seat the ring on the blocker pins of the LO range Synchronizer.
Note: To prevent losing springs, it is helpful to cover the synchronizer with a shop rag as downward pressure is applied.
Install the synchronizer assembly on the splines of the auxiliary main shaft with the synchronizer seated against the range reduction gear.
