gxr2001 Posted August 24 Share Posted August 24 Hi everyone, I’ve purchased a TD-6 with problem. I can’t shift gears while running. It will grind. I had to shut it off and select gear then start it up again. I took the plate and I also released the engine clutch pressure plate counterclockwise until the dozer started slipping when under load. Just testing to see if it’s seized up. I tightened it and I am back where I started. Tested it under load and all and it’s holding. I have 2 videos. Video 1 shows when transmission is in neutral and lever engaged then disengaged. shaft to transmission still spinning preventing me from shifting gears while running. Video 2 shows when I started it while in gear and you see the shaft going towards transmission is not moving.. then I took it out of gear to neutral and everything is spinning again preventing me from shifting into any gears. Does anyone have an idea? Is my engine clutch seized or not? To flywheel I mean? I have no experience with this at all. I tried searching to find out what’s wrong with no luck!! I put the plates back on it and I just thought if I put a crowbar on the joint and try to spin it while transmission gear in neutral will it help that of course if it’s stuck?? Will the joint hold? Joint I mean the one between the transmission shaft and clutch engine shaft. Please help. Thank you. Quote Link to comment Share on other sites More sharing options...
Dirt_Floor_Poor Posted August 24 Share Posted August 24 Just general advice would indicate that there is a possible problem with the pilot bearing/bushing and/or the transmission input shaft. 1 Quote Link to comment Share on other sites More sharing options...
gxr2001 Posted August 24 Author Share Posted August 24 Thank you @Dirt_Floor_Poor My transmission shaft has a center hole that should have a zerk. No zerk to be found but threads are present. Do you think if I take the cover off again and install a zerk and greased it...Would that reach to the pilot bearing on the other end of the shaft? Would it help? or is it too late?

McCormick 40 Posted August 24 Share Posted August 24 The clutch is not seized but the disk could be warped or coming apart so that it drags that much. There should be a transmission brake also, so is that out of adjustment or just being overpowered? 1 Quote Link to comment Share on other sites More sharing options...
hardtail Posted August 24 Share Posted August 24 It could have a transmission brake that is non functional it should be behind the main clutch in the cavity more towards the transmission Quote Link to comment Share on other sites More sharing options...

louie figone Posted August 25 Share Posted August 25 GXR2000, Get a zerk fitting into the end of your engine clutch shaft(13) the pilot bearing is a ball bearing it needs grease, it takes a lot of grease to reach the pilot bearing if the shaft is dry, it took over thirty pumps on the grease gun to reach the pilot bearing on a new shaft install. It looks like you are missing the engine clutch brake disc(9) it should be riveted to the engine clutch coupling (10). Adjust the clutch so that it takes 40 lbs of pull on the clutch lever. That looks like a 62 series TD6. 2 Quote Link to comment Share on other sites More sharing options...
mike newman Posted August 25 Share Posted August 25 ...I would check that pilot bearing .....that will most likely be the problem..... Mike Quote Link to comment Share on other sites More sharing options...
Rawleigh99 Posted August 25 Share Posted August 25 I imagine it's pretty dry and gritty in where the zerk goes. Hit it with brake clean and clean it out good with a pic before putting in the zerk. If you have a grease gun that will allow you to pump some ATF or light oil in there first that might loosen it up enough to accept grease. Good luck. 1 Quote Link to comment Share on other sites More sharing options...
just Dave Posted August 25 Share Posted August 25 You can hard pipe in a hydraulic hand pump to a grease fitting in worst case to flush pilot. The trans brake is important even with a free pilot. Good luck Quote Link to comment Share on other sites More sharing options...
gxr2001 Posted August 25 Author Share Posted August 25 Thank you guys for your amazing responses. I will take the panels off again and put a zerk in the shaft and I will keep you folks posted. I still gotta figure out how to get in between the coupling from @louie figone #9 figure/picture to install the zerk without disassemble other things. Is it possible without removing anything else to install it you think? I will inject ATF fluid inside the shaft before installing the zerk... Thank you for the advice @Rawleigh99 and to everyone else who chimed in as well. Quote Link to comment Share on other sites More sharing options...
Rawleigh99 Posted August 25 Share Posted August 25 A Porta power is also good for injecting fluid. Quote Link to comment Share on other sites More sharing options...
louie figone Posted August 25 Share Posted August 25 gxr2001 Yes you can put the zerk in as is, it is tight but it is the only way as you need to remove the zerk to pull the clutch, the engine clutch shaft will not move far enough back with the zerk fitting in place to remove the clutch. Be sure you use a zerk fitting that is extended with a 45 degree angle nipple. Quote Link to comment Share on other sites More sharing options...
Dave Mac Posted September 8 Share Posted September 8 My BTD6 had the same issue, sometimes usually after the first start. So I would have to stop the engine and restart with a gear selected, and the clutch lever in the release position then it was ok. i eventually cleaned out the grubby clutch and compartment using CRC brake clean on the released clutch, then regreased everything and it has not had a problem since. I figure it probably had some old oil/grease contamination causing the plate to stick. This machine sat outside not being used for years, so there could have been anything that got in there I guess.
