D6D Lgp Blade

If all the shimming has gone, you can machine the caps an amount, to tighten some fittings up to get the last out of them. New fittings can be purchased and requires the gouging of the welds and replacement of new balls and caps etc, any pinning will require a line bore of holes and bushing as well as new pins. I did a D6D decades ago, took some work, however did return the blade to its original tight setup.

Yes there often is a separate parts book for attachments if it is not included in the parts book you have.

Do you have the Cat parts manual? I don't have one for the LGP machine but my D6D 4Xxxxx parts manual has the blade, winch and hydraulic system included.

Hey Jfehrle,

The dozer blade on your D6 is tipped way too far back. Tip the blade to a more plumb vertical position. You do this by turning the manual adjustment arm by lengthening it. After making it longer, you'll have to use the hydraulic tilt to level it out. You might have to do it a few time until you find a happy medium. Then tilt the dozer blade and see if it still hits the track. Take a picture of your trunnion balls. That is where the dozer arms connect to the side of the Cat. Post them back here.

I bought a D6 dozer. The blade was very loose. The sideways sway back and forth was too much for my liking. So I ordered new trunnion balls and welded them on. As Wombat stated already I checked on all the dozer arm connection ball sockets and removed any shims. The cross struts needed to be lengthened to tighten up. On my dozer one was frozen and damaged, so I replaced it. In fact I couldn't find one, so I had to make one out of two others from different Cats. The ball connections were still too loose, so I welded them up and ground them smooth. With new trunnions, tight cross struts, and tight ball sockets, I was a happy camper. It's a cable blade on my D6-b. At shows people are always running it around.

You don't need a new one... just tighten it up. A little time, and some welding and you'll be happy too. I think it's hitting the track because it's adjusted too far one way. Start there!!!

Thanks Glen! That make a lot of sense I will definitely try to adjust it. The trunnion balls have about a 1/2" slack in the joints. (I'll take a picture this weekend) As someone mentioned above we could probably cut 1/2" out of the caps to tighten them up or build up the balls with weld. All the joints have about this much slack.

There are two little short arms in the front that 45 degree from the blade to the arms to keep everything tight. They have a threads where you can adjust them out but both of mine have been welded up. What are these called?
