JDcrawlers Messageboard

Ok tjdub and thanks again for your help. I did go around the seal with a pick but I'm not seeing much there. I have been trying to push some grease in there but it is really hard going. When I pumped some grease in and built up some pressure I put a crow bar under near where the 2 come together and ...

Thanks tjdub for those ideas. I'm going to get those button heads out and replace with standard zerk. I'll give your idea a try later today.
These tensioners have probably been sitting for years like that so no wonder they don't want to move.

Ok so now I tried the come along method of compressing the tensioner. Won't budge. So now I tried the wood block between the blade and front idler. http://i1117.photobucket.com/albums/k598/bozo1236/100_1711.jpg Full hydraulic force that the tractor could muster. I'm pretty sure I could see the sprin...

Hello Pete. I am not sure about the 4-219 bearings but I know in automotive bearings that ethylene glycol is a disaster. If left in there it will destroy the bearings.

Hi Pete thanks for the helpful hints. I do know about the bearing quill on the final drive. When taken off I should be able to remove the drive shaft and bull pinion and then be able to hoist the clutch housing up and out. I do have the pin located in front on the idler. I have enough rod to extend ...

Well I kind of gave up trying to beat that pin out. It is really stuck in that outside link. I think I might have to release tension and try to yank the track off.

Anyone know where I can get a button head fitting for my grease gun? Most people around here don't even know what that is.

Thanks Jack A lot of good info there. You are right I would never get under something held up by hydraulics alone. I didn't even like shoving those blocks under the tractor while being held up by the blade. I used some big 6x12 blocks under the front. The rear has two stacks of blocks under the draw...

You mean just burn a hole through them with a cutting torch? What are the chances of ruining the bushing or the link when you do it that way?

Yes congrats to CELSESSER. The winner of the backwards track quiz. The track on the other side is also on backwards. At lest the guy was consistent. Well I now have her front up on blocks. It's kind of hard to tell. You can kind of see that the track is drooping more and if you look closely undernea...

Yes I do think they have some 6x6's. I have some old fence post's laying around. The ones I pulled out when we had to get rid of the sheep. :lol: I tried beating on that pin. It's loose on the snap ring side but very tight on the head end. Can't get very much of a swing laying under a 20k lb dozer o...

Hi Richard Oh boy I get to lay on my side, on the dirt, under a very heavy blade, and wack at something with a sledge hammer. Boy make my day. :lol: whine, whine. Yea I know. And probably the reason it's like that is because some idiot just slammed the track back on, not watching what he was doing !...

Hello Tiger :D The problem is, is that the head of the headed pin is facing outward. So if I were to wack at it I would have to be under the blade arm? Well take a look at a pic. http://i1117.photobucket.com/albums/k598/bozo1236/bighead.jpg Well I got that heavy winch arch off. Now that was some hea...

Oh boy I found a problem already. My left track has a headed pin in it. And the head is on the outside. That means I would have to drive it out from the inside. Even if I get that winch arch off my blocks and the winch itself may be in the way. If the track is worn enough maybe I can compress the tr...

Hello all. I'm finally ready to rebuild the steering clutched on my old (1971) JD450B. I think I have depleted all other options except to get in there and get her done. :lol: If anyone can think of something I need to try or look at now it the time. At this point I have the rear of the dozer up on ...
