Engine stand rotater

GermantownGreen · Jan 19, 2022

Any ideas out there if this is still remotely fixable or replaceable.
Belongs to cousin, put father in law's
354 Perkins on the stand, and the internal gear didn't like the weight.
Was fashioned to be able to take motor from horizontal to upside down.
Thanks for any help, GG,. Wes from west central Missouri.

That setup seems neat, when working, but overly complex.

You could weld a nut over a hole in the top of the outer tube, allowing a blunt bolt to turn in and place a small amount of pressure to the inner shaft, keeping it from turning too easily.

Then, an angle iron welded to the outer tube with a hole that corresponds to holes drilled into the round plate would provide as many secure positions as you needed, say four. Then remove the fancy crank and stuff.

thanks for the idea, Yes, father in law had started making the blunt bolt deal, and asked that
I cruise the interweb for ideas. Everyone on here helped to make the 1800 Oliver come to life last Sat.
thanks again, wes

Cut a circle from 1/2inch plate to match the circle of the backing plate on the gear box, with a correct size center hole to match the shaft. Weld the new circle to the shaft permanently. Drill holes through both the circle, and the backing plate for a pin or pins to lock the position of the shaft. When mounting an engine create attachment arms or a plate that is near the center of gravity of the engine allowing modest torque to be applied at any rotation. I would also drill a 3/4 hole in the stub end of the shaft for a rod to pass through to control rotation. Jim

I have a home-made engine stand that someone else made, it has a #60 chain sprocket and a pin that inserts crosswise between two teeth as a lock, more or less the same plan as yours without having to drill a bunch of holes!

It is made for automotive engines so the sprocket is not real large, a more HD version could have a larger sprocket or even an 80-pitch sprocket.

not a fix but a work around

yes, thanks for that great read, that is the idea we want to work towards,
however for these tractor motors we feel like we need at least a
40:1 or even 60:1 gear reducer gearbox in order to turn that motor over, and
not have it freewheel.
That is the ultimate problem with the open gearbox in this pic, it was only
one worm gear turning a 36 tooth gear, not sure on tooth count.

i machined a piece for a guy that was going t use a brake slack adjuster to roll his engine on his stand. no idea if he ever got it to work.

With the casting off heat it up with the torch to just less than red weld it up let it cool slowly like take all day to cool then machine smooth to bolt back on. Or braze it back together. Either way don't grind it out to a veed out crack just weld it with the casting hot it will flow in besides grinding just smears the pores closed on cast so it can't soak brass in on a brazing job. let cool slowly in either case of repair.

My dad had a Farmall H. The pipe loader cracked the bell housing. He brazed it back together using an oxygen acetylene torch. It worked. We used the tractor until he sold the dairy cows.

I don't think I would ever trust that again being welded.

A cheap rework would be to take the broken drive off, replace it with a chain sprocket, say a 10 to 12 inch, mount a cheap worm gear trailer winch below, modified with a small chain sprocket attached. That would give plenty of gear reduction and would stay where stopped without freewheeling.

Apron drive gearbox from a Case IH manure spreader would work great if you know of anybody with one in their junk pile.

I have a 30:1 worm gear setup on the one I built. I've had a few engines on it. One of them was a 6 cylinder Deere diesel that I mounted on the side. I've had no issues turning any of them or keeping them in place. If I did, I'd just make a latch of some sort for the handle. I believe some of the factory built stands have up to a 90:1 ratio. Maybe if you're doing semi truck engines..

The 308 deere grain auger had about the same setup. It was a low ratio as it wore three guys out whenever we had to put in on the bin.

Do you have irrigation pivots in your neck of the woods close by? I use the gear box off an irrigation pivot. Works good and is plenty strong. A dealer for pivots might have a gear box laying around. Possibly a farmer with a pivot or two might have one laying around for an old pivot he used to have but replaced with a different model. You have to get lucky and rub elbows with the right person.
