Small end bushings for the Mk series
« on: 25 Feb 2016 at 04:06 »
I am now into a full rebuild of the top end of the Mk3 Sport and am in need of new small end bushings.
Does anyone know the standard spec dimension for the Outside Diameter of the bushing?
I'll be turning a puller that inserts the new ones while removing the old so I don't have to take the rest of the engine apart.
I can hone the ID a little after pressing them in but would like to start fabrication with the correct OD, before extracting the old ones.

Thanks!

Answered my own question - 3/4 x 3/4 x 5/8 ID SAE660 Bronze sleeve bearings from McMaster Carr are a perfect fit.
