982 hydro ???
 

My 982 is having a problem with the hydro. When you are going forward and pull the lever back to go in reverse it continues to go forward for a bit and then slowly into reverse. This happens going from reverse to forward also. This has been sitting for a while now but had always worked good until the other day. Could this be the check valves or relief valves just needing cleaning? I read to soak them in solvent, would brake/parts cleaner do the job?
I have some valves from a 149 that are known to be good. Will these fit? The 982 has the auto valves and the 149 has the button. Would they work just the same?

If the valves are not the auto type they have to have some way to be depressed to get the pressure off so you can "free wheel" it around. That's the big difference. I don't know if you could fab anything up like the flipper the 149 has without cutting into your 982, and I wouldn't want to do that...

You could use the manuals temporarily just to see if there's a change in your problem.

Could this be part of the problem? The trunion and cam plate aren't centered.
aagitch, I will try the other valves I have to see if that helps, if it does then I will know what I need to do.
I've had this tractor for a while now but just haven't taken the time to get it back in shape. Can't decide if to sell it or keep it, I really want an 1872.

Sorry, pics didn't load first time.
Also, note the homemade end buttons on the springs. I have a new set of springs and buttons to install.

I think you will notice a big difference in the way your hydro operates when you put the new springs and pins in. It also looks like your trunion is worn. There are plenty of threads on this site that address that. I would replace the pins and fix the trunion, then adjust for neutral. If that doesn't work, you may have to adjust your linkage a little bit. It takes some time but it should fix your issue. Make sure you download the service manual or purchase one from Binder Books (link at the top of the page). It will help you thru the process.

If you are looking to get rid of a running 982, there should be plenty of takers!

fixed!!
 

Well, I finally took the time to repair the trunnion on this 982. It was in bad shape as you can see in the pics. It is back to factory specs with new springs and pins. I shimmed up the cam plate and it centered nicely. I do have one question though. It operates great while speeding up but when you pull the lever back to slow down it has a good jerk (like hitting brakes) to it. It only does this when slowing down not while speeding up. It holds the speed perfect while cruising and pulling hills. It even stops smooth with the brake pedal. Could this be from the new springs being so tight?

after you re welded the hole did you fit the spring in the hole to make sure that it did not stick in any areas? sounds like you may have a very tight fit on the spring or pins, i know when i did mine i kept filing till there was no sticky points and i know this may not have been the best idea but i greased up the area. the thinking was grease will attract dirt and filth but i would rather have that over metal to metal rubbing, any way first one lasted 40 years, hoping the repair will outlast me.

Nope, I was in such a hurry to get it back together I didn't think about doing that:bash2:. That was my first concern when it did that though. Oh well, that's an easy job now that the rest is out of the way. Why didn't you tell me to do that before I put this sucker back together:biggrin2.gif:
