JD 7700 rear axle

[Jim Dayton]

Did the 7700 have 2 different rear axles? A friend has a 7700 with the low axle with 1100-16
tires on it which makes the rear of the combine quite low.

He"d like to get a higher one if available.

Jim, does your friend's combine have 11.00-16's or 11L-16's? They are two totally different tires. The 11L's are much, much shorter. Mike

I goofed, 11Lx16

i know of two different rear axles on a 7700. one is the usual adjutable one. my parts 7700 has a nonadjustable solid axle.

 

[Jim Dayton]

Will the adjustable raise the rear end of the machine?

My 7700 has the adjustable axle and it rides low in the back also, but it also has the llL -16 instead of the 11.00-16 it should have. Some 11.00-16 are really tall and some not as tall but the 11L -16 are usually always short. One other option is to hit the salvage yard, some of the 6600 and 7700's had a 20" 6 bolt wheel, or even the wheels off most feed wagons are 20", and use 9.00 -20 truck tires, this would give the lift you need.

The other picture is of my brothers 7720 it has 24" rears, but it has 8 bolt wheels. If i remember right i think the 8 bolt hubs will fit onto the axles on the 6600/7700's. If you could get the 8 bolt hubs, 24" tractor lug tires/wheels from a salvage yard it would give the 7700 a whole different look and stance.
