Here are a few photos of my refurbishment of a broken high lift jack. The casting on the top of the
jack was broken and the threads on the cylinder inside were broken. I shortened the cylinder by
3/4 inch and added threads. Then I machined up a new "nut" for the top with O ring and longer
threaded part to catch the threads. This batch of photos shows the process and also shows off
a home made funnel made from an old lacquer thinner can. It was formed from two pieces and
soldered together. The jack works fine now.
I was lucky to have a 1 and 27/32 drill and that made the repair an easy one.
My home made steady rest shown on previous posts was used to support
the cylinder for threading. It worked great. This last photo shows the home
made funnel just waiting to accept some hydraulic fluid...
