I'm still trying to press in some steel sleeved bushings into tubular control
arms for a front suspension I'm doing on my old truck. Having a devil of a
time. I'm about to think that the bushings are just too large. Tried a 6
ton press and it just stalled... had some luck with a bolt/nut/impact but it
easily destroys the bushing rubbers if it's not perfect...
the control arm bore is mic'ing 1.250 +/- .002 the bushings are anywhere
from 1.260 to 1.268. No two measure the same. It's a steel sleeve with
rubber core over a inner steel sleeve that the suspension bolt slides
through.
I'm wondering what a 'friction' fit tolerance should be ??? I'm no millwright
or machinist and I know the application/metal type/use makes a difference but
are there some general guidelines that would apply... everything I find on
the net is in engineerspeak and symbols and alchemy/sorcery stuff...
what would be considered an exceptable friction fit for suspension bushings...
.001 to . 003 ?? .015 >?? I haven't got a clue.. help me oh gurus of the
metal melding !!!!!
I've already had to cut out two bushings that hung up on me... there has got
to be a better way... I'm just not smart enough to know it.. and yes
everything is slippery as owl snot before I start trying to press them in...
