Help with woodcraft 30-20a part
« on: January 10, 2017, 06:10:00 pm »
1st off I would like to say thank you for letting me be a part of the forum. My father has a woodcraft 30-20a sawmill and I am trying to find a worm gear (speed reducer) for the hydraulic motor the lift's the bandsaw up and down. This is what happened the short chain got loose and stretched out and it jumped a tooth a couple of times and busted both sides of the gear box I took the gear box completely apart and I can get the bearing's and oil seal's locally (I have been a diesel locomotive mechanic and hay baler mechanic most of my life so rebuilding this gearbox was going to nothing... I thought) it busted both sides of the gear box housing and there is no information on the box. And we have no manuals or parts breakdown either my father bought it used about 10 years ago and there was no information that the owner had. I have looked all over the Internet with no luck. The Shaft on the hydraulic motor is 1in. Any help or information would be greatly appreciated thank you for your time.

I think the first thing you need to do is try to put it together just
good enough so you and turn it by hand to find the ratio.
Then I don't think it would be to hard to find a box.
We have a good source for that kind of stuff about 30 miles
from here It's called Trates Surplus. 570-742-2101 ask
for Gary. Tell him Kevin sent you. Also get your shaft sizes.

If its broken you can also count the teeth and get your ratio that way. I would guess its something off the shelf. I doubt  they had a special gear box made.

I would not know how to count the teeth on a worm gear...
Could you explain that part for us ? You would need to
know how many teeth moved across per one turn i'm
guessing... ?  So this would be 12 to 1 ?

since its broken you can take the worm gear and manually turn it on the spur gear or figure the threads per inch on the worm and one revolution will travel x distance and the spur gear is x diameter . I don't know if the nomenclature is gone or not that would be easiest. Most likely 30 or 40 to one. If its not set up with presets may not make that much difference which one you choose.

I do apologize for not updating sooner we got to the gear box (40:1 speed reducer) mounted. between my full time HVAC/COM. KITCHEN repair , install job and my Dad's 5 day a week oilfield pumper job and ever thing else we have going on. Anyway back to the sawmill he has found a couple of hydraulic leaks here and there and we are trying to get the leaking hose's replaced with new higher pressure one. Just to be safe. As soon as we get it running I will update. Thanks again from my Dad and me
