For you guys that might like this truck the thread is " What in Tarnation"

I lifted some fairly large engine blocks with my hoist today and two things... It needs the foot that I never did and a thrust bearing would help this old heart patient. I think I said it was 3 5/8 ID in the carrier tube. Throw-out bearing? I am ordering the crank up trailer jack leg right now.

Check Mcmaster Carr, if throwout bearing idea doesn't pan out. Not sure if they have thrust bearings that large, but they have many different flavors. Worth a look.

GB, I admire your ingenuity! You need to rig up a starter motor to run that hoist! I put one on a Cushman scooter years ago and it went faster than the gas motor ever did. Just not for long, Ha ha.

The gearing is ok for operating with the crank. Not sure I want an engine block coming in hot and smacking me on the chin! These young whipper snappers thing THEY invented the electric scooter..... And I will check out McMaster Carr. Thanks.

Looks great, super cool. Looked at putting a cherry picker on my f150. this is waaaayyy better.

Gary,
I havent followed this close. Probably late to the party. You say thrust bearing. Is this to allow you to rotate the crane when it has a load on it?
If so have you considered bearings and races from a wheel assembly? I used some large tractor bearings and races for my jib crane in the shop and they seem to work very good and can move easily with a load out on the 12 foot end. Rear axle tractor bearings were about 2 inch I.D. and 4 inch O.D. ish.
Just a idea for what its worth.
Regards,
Chris

I like the idea. I'm sure an overseas version should hold up forever in my usage. And you can see my black carriage bolts with square nuts bleeding some blackness onto my rough cut side boards. For you I guess the boards should be planed if your business name will be lettered.

A good tapered bearing should be good for the "top" bearing to carry the load and allow easy rotation. But, the bottom end of the rotating shaft will need a bearing too. (Just think that the moment caused by the weight of the item being lifted times the length of the lifting arm will be carried by an equal moment on the shaft being rotated in the stationary member welded into the truck body.) A simple caged roller bearing (not tapered) down at the bottom of the rotating shaft.

Been a year or so since I started this. Lifted my 650 lb welder this afternoon. No leg on the bumper yet, maybe next weekend. This went very smoothly just the way it is, but there's always room for improvement. Been using old wrenches for bracing as I was given a 5 gallon bucket of big end wrenches after a neighbor passed away. The star of the show is this amazingly smooth and powerful winch. It is every bit the Swiss watch with it's fine toothed ratchet and the magical ability to easily lift that that welder and then effortlessly lower the load just by cranking counterclockwise. I have no idea what is happening inside that enclosed cast aluminum housing, but I do believe in magic now.

Go to the 3rd picture, click on it. Then stretch the pic to enlarge it.
Now see the thickest part of the mast just below the top-side-flange of the bed. there is a brace extending forward to the bed side.
More obvious us the black shadow cast by the sun. It appears as a diagonal slant from the mast to the body. Old wrench.

There are 2 wrenches involved. The long combination wrench to the bedside and a one ended open end below it, rolled around the base pipe and welded to the stake pocket. The stake pocket was already all patched up by a previous owner.... It's all just some hillbilly stuff cobbled trogether with what I have here on the place.

Good find!

Back in the 60's and early 70's I did service work for a local propane company. Every service truck had one of the bomb hoists to load heavy items. More than once I've wished I had bought one when they were available.

This type of behavior can be carried to an extreme as witnessed by this photo from James Wagner's 'Ford trucks since 1905'. Ok, and another, just because.

Thanks again Pete! I can see a Tee shaped foot or outrigger on the right side below the hoist.
