reverse clutch 18-g 1988?

I am currently working on a few different gravely ride on mowers. what I have found with them is that the reverse clutch on any of them doe's not grab with any real force. I'm thinking that the clutch is glazed and I'm going to take them apart to deglaze. Or are these tractors reverse clutch just did not grab well. I do have service manuals so I know that I am very close to the proper gap space. I believe that they are 1985-1988 I have not dune to much research on them yet they have 18hp Koler motors and on 0ne of them it says 18-G professional. If any body Knows about this it would be greatly appreciate it.

First set the gap in both the forward and reverse clutches - there is a procedure in the stickies. Then test operation and check for glazing if reverse still doesn’t engage well. A properly functioning reverse clutch will grab just as well as forward.

Re: reverse clutch 18-g 1988?

Are you asking if the tractor can be placed in reverse and the direction lever or pulley released? G series tractor do not have the ability to be locked in reverse and the control released. They are designed to be held in reverse manually.

Re: reverse clutch 18-g 1988?

I'm still not sure about much with the tractor, I have four of these gravely's that my wife's aunt is asking me to get running. I now have two running and working but the reverse is not strong on either of them, one is a lever shifter the other is pedel and I have found out that there is no lock for reverse. when I get a chance I will post picture's and some real info of what they are and what condition they are in. Thank you

Thomas, maybe someone needs to also explain that the reverse gear ratios are different from the corresponding forward gear ratios.

The tractor backs up slower on purpose, it is in the design of the transmission.
