8640 Quad Range HARD shifting ??

[4020guru]

it has only one shifting handle . Shifts thru the letters just fine, but when you cross over to shift 1,2,3,4,1r,2r, gears I have to use alot of muscle to shift and move the lever. It powershifts fine. Could this be a shifting cable problem?

sounds like a cable problem

I agree a cable problem,,also give the bell crank under the cab some grease, it is a forgotten area for lubrication...

Most likely a shift cable but follow Tim's suggestion, too.

He's gonna look long and hard to find that "bellcrank" to grease! The early-design 8630's had them, the late design 8630's and ALL 8640's had longer shift cables, eliminating the shift rods that dropped through the cab and their attached bellcranks.

Your right,, I was thinking the 8630 with the bell crank,,can't grease the Darn thing if it's not there...

Yep, I've got an 'ol 8630 with all that added mechanism in the shift linkage. Still works reasonably well, though!
