Hey Guys, just picked up a 1952 styled AR. serial number 279226
Much to my disappointment a few weeks after getting it, I found the crank splines that mate with the clutch drive disk have been repaired, poorly. Gave it a wiggle prior to purchasing anyway wasnt noticable, more noticeable after the 25 km ride home! None the less a good drive!
So my options appear to be try to find a good crank or repair what I have, to me it looks like a poor repair, sloppy welds, which may make repairing harder now. Who ever worked on it reassembled the clutch drive didnt allign the timing dots oviously because of the poor fit....
Anyone know of a reputable welder/ machine shop in Ontario, Canada with this type of repair? I'd consider sending it to the states?
Many cranks I have found have been machined and would require .020 bearings.
Are there aftermarket crank bearings available for the AR? I see shims in the parts diagram, I've never torn a two cylinder down, I can't imagine these shims adjust for .020" ??
It appears to be different bearings compared to an A, is this correct or can I use A model crank bearings?
The crank is a A3322R
Unfortunately my motor has the babbit rods (A2344 casting number) so if I gets new crank that has been machined I will need new used rods with the inserts, I believe the A5350?
Any and all advice interns of tearing it down and swapping crank is welcome, I'd like to make it right! It's in reasonably good condition, newer paint, starts and runs nice. I had bought expecting some electrical work etc but wasn't counting on the crank splines being chewed! Ill attach a photo later of the splines.
I'm new to the 2 cylinders but have a decent mechanical knowledge
