 Topic: HD-16 Track adjustment
Posted: 14 Aug 2014 at 2:14pm |
|
We have a 1955 ish hd-16 runs and operates good. the tracks are a little loose. I can remove the adjusting lock and back it off. However the large adjustment screw is frozen. I have soaked it down, and heated the middle of the yoke. i can bearly get it to budge, under heavy heat. and ideas??

Is it new enough to have a grease nipple for the threads? If it does, you can try getting grease or solvent in that way.
Heat + candle wax?
Longer handle?

Yes it has grease fitting in the threads. How much of the yoke has threads in it? I took the fitting out and soaked it with penetrating oil. Then heat. Followed by grease. The grease was going in.
Please tell me more about candle wax. And dose the large adjusment screw simply use the spring houseing as a bearing? Or dose it somehow tie into the mechanical items in the spring housing.

I've got an HD11, but it should be similar....
I think mine has about 4 inches of threads in the yoke. You say the grease was going in. Is there any coming out? Around the threaded shaft? Or maybe it's all going into the yoke. The HD11, the hole for the threads comes out at a hole up against the front idler. Mine had round plugs welded into the holes though to keep dirt out.
When the screw is backed off, it will come out of the spring housing plunger. The end of the threaded shaft is a ball that sits in the plunger.
Candle wax: The theory is that you heat up the object in question, then as it cools, you melt wax and let the wax run into the threads to lubricate it. Truth be told, I've only done it a couple of times. Easier to do when the threads are pointing up instead!

How slack are the tracks? If you can push the idler forward with a jack or ??? you can lift the front of the yoke up to clear the pins on the idler. I need about 3/4"-1" for my HD11. That's a fair bit of slack though....
