The HD15 should be  12volts and the plunger rod  is bad condition if she jumps out of gears and if she jump   just one gear that gear is bad condition.

Thanks for the reply’s !   I haven’t ran the dozer yet I just started cutting it out of the bushes yesterday the engine isn’t locked up and I’m gonna make sure the rack is free. I think he had the pins and bushing turned not to long before he stopped running it   But the sprockets are pretty worn.   There is a place in Texas the sells new sprockets for the hd15 tho

Another question I have is dose the hd11 steering clutch’s fit the hd15?    Mine isn’t supposed to have steering clutch problems but I found a company that makes steering clutch’s for up to the hd11 and if I ever need some I know where to get new ones

General Gear in Idaho has lots of after market steering clutch parts, so a good place to look for hard to find parts.
