So we are in the middle of slowly rebuilding the engine and tried to install the new 'Main Bearing Set' from JK:
http://www.justkampers.com/vw-t2-bay-window-parts/t2-bay-engine-parts/general-engine-parts/070-198-461-main-bearing-set-1200cc-1600cc-aircooled-engines-1960-on.html" onclick="window.open(this.href);return false;
It says that they are: 'Standard size bearings, fits all VW (upright - I think they meant flat 4 as VW did not make an upright aircooled) 1200cc-1600cc aircooled engines, 1960 - 1982.
I took my bus of the road years ago, but as much as I know, it is a standard 1600 engine.
Anyway, the new bearings are too loose in the case casting recess, they wobble around, yet the old ones fit mm perfect, flush, tight and do not move.
The new and old bearings are different part numbers.
So I am wondering if the case has been bored out for some reason and if anyone has seen this before?
Old Bearing
New Bearing
I found this excellent resource which seems to suggest that re-boring cases for repair is quite common, although, I have not had a chance to measure my case properly yet: http://61vdub.blogspot.co.uk/2012/01/bearing-sizes.html" onclick="window.open(this.href);return false;
Anyone have any idea what the situation is, do I just need larger bearings?
