1950 D2 low seat left steering clutch problems. Was working fine when the owner parked it 2 1/2 years ago, but now there is a lot of free play and when you pull the steering lever down(all free play)it will hit a solid spot about 3/4 of the way down and stops with a slight bit of movement if you really lean on it. What does it sound like to you guys and is there any easy fix? Serial #11,300+-. Has been parked outside with a tarp over it.

Clutches have rusted and swelled so the clutch pack springs are nearly completely compressed. Almost certainly a teardown and replacement will be required though .....IF....... you can get the clutch to slip it might be possible to just keep adjusting the clutch to keep the recommended free travel measurement at top of lever and run it until the swollen clutch linings break down from rust between lining and backing disk. Most likely you cannot get the clutch pack to disengage/slip at all.

All parts to repair are readily available. There are modern bronze faced linings available that do not swell or absorb moisture so rusting is minimal.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

Could be the linings, but it sounds almost identical to a D2 I worked on last summer. The throw-out bearing were both losing their balls. If you have a bore scope you can snake it down in the clutch housing and take a look. You can really see it with your eye through the cover.

General Gear has the Bronze lined plates and replacement steel disks. Neil did a long Thread on reworking clutches and final drives, I am sure he posted the throw out bearing part numbers? If SEARCH doesn't easily turn up his Thread, give him a day or two to reply here. Also read through Mr Potatoehead Thread listed down lower on the main page as he needed help doing what you are going to be doing soon! Might even be a link to Neil's Thread in there!

This is a website for General Gear in Idaho. They offer the metallic bronze/ steel discs that replace the standard frictions with riveted linings (4B3533) that tend to rust and swell. They also sell the steel disks 4B3532 that go between the frictions as well as new brake/clutch drums 5B3281 that are frequently broken trying to get the final drives off.

The clutch release bearings are a thrust bearing, part number 2B9338. Always a good idea to replace if there is any question it's good. They can be converted to grease lubrication as well.

Yes it could be frozen clutch disks or throw out bearing. Before tearing down check and see if the bell crank is not tight. Look under rectangular plate. You may be able to move with a bar and restore proper free travel. If so, lots of loose juice and moving back and forth with bar may restore operation.

Sounds like a frozen disk pack due to the sudden stop - the slight extra movement is likely torquing of the components. Review this thread http://www.acmoc.org/bb/showthread.php?28065-D2-5U13753-master-pins-please-check-my-understanding/page4&highlight=steering - main clutch material is between pages 4 and 9 but look through all 21 because there are a few other nuggets of information in there.
