#1930 puts it into 1956 production, per Wendel's book...

| 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. |
