I have ONE tight conrod on my about to be re-assembled motor - single port 1500 for a restoration - not a racer.
I purchased a new VW OEM crank, P&C's but did not replace the conrods as they appeared to be OK after mic'ing up, but alas one is tight. Side clearance is OK but, zero clearance when plasti-gauging on parts of the rod journal. So I guess it might be out of round or has a few spots that are distorted. I tried to measure the inside diameter with the bearings installed, but get varying readings on the circumference of the rod which does not make it clearer if the rod is out of round above the limit.
I've shifted the offending rod to another journal and it is still too tight, have swapped bearings from another OK rod to the offending rod and it is still too tight. So I discount the bearings to a certain extent.
I'm looking for one good used original rod to see if the problem is the rod or the crankshaft. I want to test this before I go to the expense and hassle of having to get new rods, small ends honed and disassemble the crankshaft to get it machined.
Anyone got a good used one or a set if you are unwilling to separate?
Also anyone know where in Sydney I can get the small end bushings honed to fit if I have to get new rods?
Please PM me.
