Geared engine stand

In preparing to rebuild my 5.4 DOHC for my 96 Cobra I realized how much I HATE trying to spin that heavy ass motor by hand. I have always wanted a rotating engine stand but, I can't bring myself to spend that kind of money. So I decided to convert my cheap stand. I used this winch https://www.harborfreight.com/automo...inch-5798.html (with a 20% off coupon it was less than $23) and a few hours of spare time to make it happen. One of the major design flaws, as I see it, is that the geared stands available do not allow the removal of the "head." It is much easier to attach the head to the block then use a hoist to lift it into place, than it is to hoist the motor in the air and try to attach the engine to the stand in the air. I made mine removable. The gear is a removable add on. Simply remove the 2 silver bolts in the pic to remove the gear and remove the head as normal. Here are a few pics of the finished product.








and a video of it in action, since my 5.4 block is still at the machine shop I used a spare 4.6 aluminum block I had laying around.

Good stuff!

Another option would be to put the shaft on roller bearings, but that would involve more work that the winch method.

I'm trying to source some pipe and bearings to make that happen. This is only step one of my overall plan.

What keeps it from free spinning? Is the roller winch a ratcheting style?

Since it is a worm driven gear it wont free spin. With worm gear setups the driven gear cannot transfer force back to the drive gear. The drive gear acts as a brake. I specifically searched for a low budget worm gear setup. I could have easily used a boat winch with normal ratchet style gears, but that didn't sit right with me.

For more info check out this page http://www.technologystudent.com/gears1/worm1.htm

I did not know that about worm gears.

Too much work... remove that crank and use a drill or battery powered impact.

Just kidding on the work part, nice job. I have seen stands that uses a drill tho.

I've considered attaching a motor to this, but I asked myself, "just how lazy am I?" The answer was, very lazy. I just don't want to deal with a wire plugged into the wall or having to keep a battery charged.
