Hi Mike. Thanks for the quick reply. and your encouragement.
Luckily i have all the time in the world for this project.
I have a few more Q's for the brains trust. I cannot find a master pin on the tracks. can i just knock out any pin?
Also i plan on removing the track frames. Is this just a matter of removing the large nut (looks about 2 1/2") that seems to hold it to the shaft? anything else i should know about?
thanks in advance. I'm sure there will be more dumb questions.
regards
steve
Also. We had 3 1/2 inches of rain last week. The new D2 pulled a set of discs all day long. Including through the wettest ground. It did'nt even feel like it was any trouble. It is a far more capable machine than we expected and will get plenty of use.
There are no dumb questions when working on these old Cats, only dumb folks who don't ask before starting a job they know nothing about, I do that all the time.😆
(1) There is no Master Pin on the 2 Ton tracks I've seen, the very early chains had either a square head on the pins with a dowel at the other end keeping them secure in the chain, or 2 round ends with a dowel each end, or like your D2, interference fit pins that need to be driven out. Apparently D3 track pins are the same diameter as the 2 Ton, but a bit longer and need to be trimmed to length, I bought one a week ago from the Cat. Dealer but haven't tried fitting it yet, cost was about $7, cheapest part I've ever bought from Cat. I reckon, Part Number is 6B5278.
(2) To remove the track frames you need to remove the main spring obviously, and then undo that large nut, lifting the track frame at the front tilting it to clear the rear sprocket as you slide the frame outwards, try and assess the wear on that track frame as you are lifting it out, you might need to rebush it so your track frames are straight again. You know the drill Steve, go slow and safely, even a 2 Ton will hurt if it lands on you!😆
(3) Good news on the D2, glad she is getting the flogging she deserves!
Keep the stoopid questions coming, there's a lot of schmarter folks than me on these Forums, lurking in the shadows.
regards
Mike.
