Eaton Fuller Clutch Cross Shaft Bushing Driver

A one-piece stepped steel driver made for one job: installing the clutch release cross shaft bushings in the clutch housing of an Eaton Fuller heavy truck transmission. The pilot end locates inside the new bushing and the shoulder behind it drives on the bushing edge, so the force goes straight down the bore instead of cocking the bushing sideways.

Worn cross shaft bushings are what give you a clutch pedal that feels sloppy, a release fork that will not adjust out, and uneven release bearing travel that chews up the bearing and the clutch brake. When the shaft is out for a clutch job it is the right time to replace them. The problem is getting the new bushings in straight - a socket and a hammer tend to catch one side, crush the bushing lip or shave it going in, and then the shaft binds when you slide it back through.

On the bench: clean the housing bore, set the new bushing on the pilot, line the driver up with the bore and drive it in with steady hammer blows until it sits at the correct depth. Repeat on the opposite side, then check that the cross shaft turns freely through both bushings before you install the fork and lever.

Knurled handle section for grip, black oxide finish, about 11 in long and 2.5 lb. Confirm the bushing size on your clutch housing before ordering, as Eaton Fuller housings vary by model and year.
