Clutch adjustment- Won't shift into 3rd or 4th gear.

Postby tomch » Mon Oct 03, 2016 11:55 am

I have a 1974 IH Loboy and for some reason it does not shift into high gear. It easily shifts in the low gears and occasionally it seems to slip into 3rd or 4th. Is there a simple adjustment for this?

2 R

The above shift pattern is what I currently have, but 3rd gear does not work.

Below is the Shift pattern from the manual.

R 2

Let's back up. If this a standard Cub, standard Cub Low-Boy, or a numbered Cub - - there is only 3 gears forward and one reverse as indicated in the operator's manual. The only exception is a numbered Cub with creeper gear. The creeper reduces each forward or reverse gear by about 50%.

Disengage the creeper, operate the tractor in each gear. If the tractor works in each gear, then engage the creeper and operate the tractor in each gear. This will narrow down the problem area.

If the clutch works for some gears but not others, not the problem.

Report back.

Edit: After reading the initial post about 6 times - - - what is the history on this tractor? I don't know if it is even possible to assemble the transmission gears backward, in reverse order.
I have an excuse. CRS.

Sounds like you need to remove the top shifter plate from the transmission so you can inspect the shifter and the shift forks.
I would suspect an issue with the shifter assembly. Look for a worn shifter ball, loose H pattern plate, or something wrong with the shift forks.
There are some how-to's on rebuilding the shifter assembly.

Number Series or Std/LoBoy Cub? From your initial post, looks like the trans cover/shifter has been rotated 180 degrees. I don't know if this is possible but someone will post with the correct info. As Eugene said, the Cub transmission has 3 frwd and 1 reverse, so the heading reference to 4th gear is confusing. Stan

Quite possible that the transmission/shifter cover is installed backwards. That would explain the upside down shifting pattern. Easy fix.

R and 2 on the cover should be towards the front of the tractor and the numbers right side up when sitting in the seat.
