    I have a D21P-6 and I am looking for the part number and availability of a few things. One is the clutch pedal return spring. It is mounted at the end of the clutch cable and is secured to the side of the transmission. This is the spring that gives your clutch pedal its springy feel. The...

    CAT 955 starting troubles

    This past weekend my dad and I fired up his old dinosaur (CAT 955) He has always told me that it is a 1957/1958 or what ever year was the last naturally aspirated engine. After he threw the right track (and then the rain came) we spent Sunday morning putting the track back on. After we got...

    D21P-6 track adjustment I am having a little trouble understanding the manual on track adjustment and I just want to make sure I get it right. The book gives a tolerance of 20-30 mm. Where is this measured from? I just want to make sure that my tracks are adjusted correctly. I know to pump...

    D21p-6 Does anyone know if the fuel cap should have some time of o-ring or gasket inside of it? Mine doesn't and it seems to be a little messy

    Thanks Darin. Darin, Just got everything back together earlier today and it works like a champ. You have been very helpful and expeditious with all of your tips. Hope not to need to many pointers in the future, but it is good to know someone like you is around.

    D21p-6 Darin, Thanks for the help again. This is 121mm to the inboard point of the adjustment bolt right? Is that with the yoke up against the clutches? What I mean by that is with the yoke full left or full right. Is there a good reference point for the center of the machine that you...

    D21P-6 steering clutch adjustment I just put my new clutches together and dropped the pack into place. With the freshly rebuilt clutch pack installed, what should the adjustment bolt on the release yoke be adjusted to? Any incite would be greatly appreciated.

    Darin, I finally got the steering clutches out of the machine (D21P-6). They feel a little gritty and some of them are pitted, but none of them are stuck together. Is the grittyness normal or should they be sleek and shiny? Do you know what the fiber measurement should be on a serviceable...

    D21P-6 clutch removal How far should the clutch pack recess into the outer drum? All the way or just some? I broke it loose with some scrumf and BFT's, but it just doesn't want to come out. Thanks again for the help:Pointhead

    Darinray and Jolley Giant, I have been following your recent conversations about Jolley's steering problem on his D20p-6. Funny thing is that I just bought a D21P-6 and I am having the same problems and everything in those pictures I am seeing in front of me. By the way, the pictures have...

    Thanks for the Help, but one more question This D21P-6 doesnt want to steer left. When I pull the lever nothing happens, I don't even feel a little resistance. He claims it worked fine when he parked it. The right side works fine. I am willing to do the work, but I just want to know what I...

    Komatsu D21P-6 question about shifting I recently went and looked at a D21P-6. This is the first time I ever operated one of these little wonders and was definitly impressed, but I have a question about the shifting . When I would shift into forward 1 there was a little hesitation and then...
