Yes those >25 year old o-rings are probably shrunken and rock hard. They're
going to be letting a lot of twist'em slip past.
Unsolicited advice but if you dug it out planning to start using it
frequently then put the money you'd have spent on a rebuilt kit toward a
high-torque cordless impact instead. I have a big 220V compressor that has
been relegated to blow gun and air hammer duty because I like the battery
powered version of every other air tool I own better.
