Title: Steering Head Bearings Redux
Post by: imported_n/a on June 15, 2019, 01:18:47 PM
Need some advice on how to remove the "Inner" bearing races on the steering column '73 Jackpiner frame. The "Outer" races came off the tube with ease using a punch in the holes allotted.  But, can't get the "Outer" races to budge. Have tried several long punches, a long chisel with flattened edge, a piece of 1" dia. pipe – all while pounding with a Dead Blow mallet. They just won't budge.  Any suggestions?!?  (can't heat things up since the frame's already been powder coated... yikes). Do I just need to add some Liquid Wrench and a little more muscle?  Thoughts?

Thx in Advance, Chris H.

Chris,

Take a small piece of scrap steel and tack weld it across the race.  Then you will have something tap to knock it out.

Thanks,

Kevin

Chris,
 You're doing everything right, except you need a steel hammer. If the powder coat is over the bearing race, take a razor blade and divide the two parts, for sake of saving the finish from tearing.
