47 ES2 crank shaft specs ?

Forums

Is there a min/max diameter on the shafts (drive/timing bearing placements) or is it just a nice fit with out any slop when the bearings go on? Hope this helps makes sense?

Thanks.

The bearing should be a light drive fit onto the crankshaft, that is using a suitable tubular drift you should be able to tap them on using a small hammer, Heating the bearing in a hot oil bath or induction bearing heater to expand it to fit is also possible.  If they just slip on its time for loctite.
If the inner races are not secure, they will revolve on the shaft/s in service. this is easily seen by a 'polished' looking finish on the shaft.

I've found Loctite a waste of time in this situation - the shaft has to be built up by plating, or other means and ground to size.

I think I used the grade recommended for permanent assembly of gears etc, and would have sprayed the shaft and bearing with loctite primer, after a thorough clean.
