Is there anyway to confirm that connecting rods are available before becoming a member? I know this sounds disrespectful, and I don't mean it to be. I am repairing this bike for an elderly gentleman and probably won't run into another Ariel Square Four on the bald Prairies of Alberta Canada. I would...

Where can I purchase Ariel Square Four connecting rods?

Thanks for your help!

Yes.

The inside of the seal is beveled but it will fit either way.

The term oil seal washer is a tad odd; is there supposed to be any rubber on them? Mine, which appear to be original, are just plain steel. Did I mention that this is a bike in a box, disassembled in 1978?

Will I have to relieve the crankcases in order for the new rods to fit?

My concern stems from twin cylinder BSAs who's oiling system is similar to the Ariel's; .006" is way too much, starves the left hand rod.

Good answer, clear and direct! Thanks!

The bolts are new old stock with castleated nuts. Unfortunately, I have only found six bolts. They came under part number 1096-48. Nuts were sn3. Is the small steel washer under the nut used on all the square fours?
