I did some distributor work on my 574. Of course now my timing is off. The marks on the pully are terrible and impossible to see. I found some timing tape online. Does anyone know the crankshaft pully diameter on a gas 574? My body won't let me bend or crawl under to try and measure. Haha. Thanks!
Hi All, I have been following this forum for quite some time now (it has been extremely helpful!) as I work on my 1950ish td6 crawler. I have finally become a member so I figured I would share my experience in case it will be of help to anyone else. This crawler was purchased by my great grandpa (I am only 22) for use on his tree farm. He had plans for some sort of hydraulic lift in the front of the crawler that would grab small trees and lift them vertically to be placed in new locations, however it was never completed. The crawler had been sitting for maybe 10 years before it was moved just a few feet to park it in a new location by my dad. Since then it had been sitting 10+ more years (tarped) before I took interest in it. My first task was to get the crawler started on gas. It had the fuel tank relined and carb cleaned but would not start. Long story short, the magneto timing was 180 degrees off meaning it was trying to fire in the intake stroke. With that fixed, it fired right up on gas. I bled the diesel system and it switched over no problem. One of the reasons it had been sitting without use was that the main engine clutch was frozen solid and always engaged. I was able to find a replacement clutch disc online and pull/replace/clean the clutch and flywheel etc. Then the clutch required some adjusting in order to get the lever to lock in position with less resistance. Started the thing up and was able to shift into all 5 gears and it ran great (forward and backward only ) I read all the posts on people trying to get steering clutches loosened up but with no success. I figured it would be best to pull those beasts out and clean them up. Those are not light haha I have currently pulled the right steering clutch out (didn’t need any compression tools but tight fit) and disassembled it. To my surprise the clutch discs were not a solid piece of metal but actually came apart quite easily. I have cleaned up the drum and all the components except the discs, which take forever (a little work each day after work at CNH haha). One of the tricks to getting the clutch disassembled was to unlock the nut from the shaft by hitting those tabs back. I did manage to rip the gasket in the clutch compartment that seals the compartment from the transmission when I removed the clutch. Is there somewhere I can get a replacement gasket. I haven’t found anything and will probably have to make my own. Is there an easy way to clean the rust and debris off the discs? After I get those cleaned up it’s on to the left steering clutch. Then new wiring and some day hopefully some fresh paint. Also just got the tracks loosened up as they were very tight. I purchased a button head lubricator (7/8) adapter for my grease gun but am having second thoughts about packing the rollers with grease after reading up on it. Anyone have suggestions? The seals show no signs of leaking and I don’t want to damage them. Well this is where I am right now. I know you guys love pictures so I will try and post a bunch. Thanks!
I believe I understand correctly that there should be a timing pin near the crankshaft pulley, but I do not have one. Can anyone tell me if I'm just not seeing it or if mine has broken off? If it is gone, where do I put the replacement? Thanks in advance for the advice and encouragement you've given so far on this board.
