MC Connecting Rods and Cylinder Clearance
« on: April 25, 2016, 11:54:51 AM »
I've noticed that nearly all the aftermarket connecting rods I find come with the caveat that the cylinder skirts need to be notched to make room for the new rods. I've seen this done on a couple youtube videos (Hackaweek was very helpful). However I don't have access to a mill. Anyone know if this could be one by hand with a Dremel? Just keep slowly notching it down until clearance is met. Seems like this could be do-able unless I'm missing something. Thanks

The notches on mine were about 1 1/2" wide and about 3/4" high...roughly from memory....that's alot of dremelling.

...and you'd want to be certain to get all 4 pistons equal weight. It shouldn't be expensive to have a shop (automotive machine) do this for you and insure the results.

  He's notching the cylinders not the rods. A Dremel's a bit light weight but a die grinder could make some good progress.

Thanks, Don. Read that and completely gelled in my mind's eye. Kept thinking piston skirts... Sorry Nalex-

Die grinder and carbide burr, then smooth edges with a stone on the die grinder. Dremel is probably a bit small of a tool for that job.

Thanks for the responses guys. I do have a die grinder, as well as access to a pretty heavy duty bench grinder with medium and rough stone wheels. The bench grinder might work out quite well, then use the dremel or the die grinder with a stone to smooth out the edges.
