Modifying and increasing the life of my 18 year old Craftsman motorcycle jack. 

I filled my jack with ATF and never have problems. It must treat the seals so it doesn't have that problem. Runs smooth as snot on a door knob!

Thanks, after watching this I drained and replaced my fluid. I had always just laid on the side and added fluid without removing the jack, but this is much better. Good stuff!

Great video and idea for making the jack lower smoothly.

I just bought a Sears Craftsman motorcycle jack that was several years old as there are no new Craftsman jacks in any inventory anymore. I chose the old Craftsman because many of the current models are cheezed down on quality. The new ones have much less metal and the designs have shrunk down the heavy gage main frame with less bracing and no metal around the front wheels. The Craftsman jack is a beast and weighs probably 10 pounds more then the Harbor Freight and all the other knock offs. So this gave me the opportunity to buy the best at less costs and clean it up and refurbish it which I've done. I first sanded all the rust off the frame with small wire wheels and flap wheels on my drill. Then use Rust-Oleum (Rusty Metal Primer) on the whole frame followed by the Rust-Oleum Semi-Gloss Black brush on top coat. The red parts I bought a spray can of "Cherry Red" Rust-Oleum metal paint and sanded down all the rust and sprayed that on. Next a lot of the hardware was working but looked bad - especially the Acorn Nuts used on all the pivot points. I bought new stainless Acorn Nuts and some lock and flat washers and got rid of all the rusty bits. On the platform top where the motorcycle sits I replaced the rusty Acorn nuts with some stainless steel lifting triangle shaped eyelet nuts. The Craftsman has all M12 heavy duty fasteners. These triangle (eyelets) can be attached to the bike at first contact and the bike will not go anywhere during the lifting process unlike the loops down on the base cannot be used until the bike is fully up in the air. (good luck with that). I've posted the final assembly build and modified skid plate on a Kawasaki Versys X300 to allow it to be lifted up in the air.

Hello Tank, thanks for the comprehensive video. Your video shows up when I search for a “craftsman 50190”. I bought a used jack a couple of days ago and got my bike on it (Sportster). The jack keeps leaking whenever I pump it (with or without bike). Would a oil change service help or would I need to rebuild the bottle jack? I don’t have a vice to break it down but would appreciate your help if you could share what serviceable parts I could start with. Thanks for your help !

It won't just slide under the heritage I have, does it just slide under you bikes

Hi, are you available for questions?

I have the Craftsman 50190 I just picked up free because it would go down. I pull the plug at the bottom to get it down but the jack foot pump doesn't move and won't do anything. What should I be looking for

Sorry but did you skip how to bleed it
