Im new to dozers and have a 350b that has a broken sprocket and am wondering how you get the track apart. I have looked and looked and cant find anything that looks like a master link. any help would be great. thanks
one of the links will come apart. just drive the pin out. it can be hard to identify which one especially if muddy. usually its a little egg shaped in the hole which helps id it.

pictures and everything. nice find. it at one time had a snap ring but it could have been welded in by now. take one track pad off. makes it much easier
Don't let Bert fool you by making it sound so easy. Believe me, I have broken down more track than I care to count, and some of them can be a booger bear. If it has been welded, then it was probably welded on the inside. Look close. got to find the master, as you will never beat out one of the other pins. Takes a very strong press for the rest of the pins.
When we took ours apart a few months ago, it came apart pretty easy. I'd have to ask Angel for sure, 'cause I wasn't there, but I do remember before hand, helping them find the master link. It was sunk in about a quarter to a half an inch. I think they said it punched out pretty easily without fuss.
Those 350's-- I really dislike the fact that you have to break the track and take the final drive off in order to replace the steering clutch or brake. Seems like on my dad's Cats and Internationals, you could replace brakes or clutches without major surgery. Not so the 350.
(some) of the master pins has a small drill hole in the pin SOME of the master pins ar (little ) longer but you can heat any of the track links around pin and drive them out have 3 350 if you find the master pin we put grind marks in the track pad by the master pin easyer to find next time ps the master pin can be a pain be care full not to mushrom the end of pin GOOD LUCK
some pins drive out and some have a master pin with a heavy snap ring holding the pin in. I have 2 350's and each are different. If it drives out just remeber "Don't force it, just get a bigger hammer". The ones with a snap ring do not fit really tight and have a flat place on the end so they wont turn.
to take the track off a 350. jack the back up. master pin should be over the front idler. take the pin out. if you are taking the left side apart start motor hold right steering lever push clutch put trans in reverse slowly let foot clutch out to rotate track. to put it back on. a pulp hook works pretty good put track on sprocket rotate ahead. dont forget to let the greese out of the track ajuster before you take anything apart
