Manual Transmission for FC (was Re: Question for John H.....)

[Mike Hohnstein]

The unit I have is 14%, effective 4.55 final drive in OD off your 5.29. Eaton
auxillary transmissions have a bunch of ratios. Adelman Truck Parts in Canton
OH is where I got mine. Paid a grand for it with new bearings and seals. Had
to fabricate a mounting arrangement, get new shafts made and do up a shifter.
Probably took 30 hrs.
My plan is to install the Roadranger this fall after we get back from out west.

Mike,

Would that be applicable to a 77FC35 CAT3208 ?

What would the end result be if so?
