[DeTomaso] A-arm bushings...should they require machining?

[grayjim]

Dear Chuck,

I had the same experience. Rubber hard to get out, urethane easy to install.

Any driving scheduled for the weekend? I have to go to Duncan on Sat for a 
funeral.

Dear Joe,


                    I  don't know.

                    I do know that twenty odd years ago when I converted
both Panteras to polyurethane bushings from Pantera Performance Center, they
went in with just finger/hand pressure.  No press needed.   Obviously, they
must have been smaller than yours and I don't understand why there is such a
great difference.

                                      Puzzled,  Chuck Engles

I have removed the bushings from the front A-Arms and have found their ODs
to be a consistent 1.184".   the A-arm bore IDs varied slightly around
1.181".   this makes sense as the IDs would be 30mm with the bushings
oversized for MY expected press fit of ~ 0.003".



NOW, the new bushing ODs vary around 1.189".   to ME, that is way too much
press and could plastic yield the A-arm bores.



Is it expected to machine the new bushing ODs?  (Pretty common practice for
new parts to be oversized for field fitting  in the machines I use to work
to allow for possible damage/wear.)

OR

Throw away the micrometers and get a bigger press?
