I came across a 58 or 59 D4 with 5 roller frames, and pony start.
Over all the motors seam to be good, and it seams tobe complete.
The down side is that one of the front idelers needs a bearing,
the seal onthe hydrolics leaks realy bad, the injecter pump leaks
( I think its just a gasket) and it may need a set of tracks soon .
although the rest of the undercarriage is 50% or better. The guy
wants $3000. I would like any thoughts or advice, anyone has.
Also being a little bit of a newbe still, could anyone tell me why
They had 4 and 5 roller frames and advantages or disadvantages
to them. Thanks.
