Hi fellas,can different circlips,other than the original (new) be fitted. They just seem a bitch to fit. Don't fancy paying out $60 or so for the special tool when only using the once. Just wondering if more modern ones could be fitted,the ones with holes in for pliers. Or does anyone have any homebrewed tips for fitting.
Regards.

Try a socket to set the clips.

put a clip on the pin before you put it in the piston... I would only use new clips, because when you pull them off with pliers and screw drivers , the clip gets bent. use a socket to push them on. I have the tool. believe me! It makes them so much easier to put on.

If using stock older style 45 pistons and pins, no other clips will work other then the very stiff "L" section factory type. A perfectly adequate installation tool can be made from a tapered hardwood dowel and a piece of PVC pipe.

This is the factory tool. The large sleeve is hollow.

Ok, curiously I read this post yesterday and then today I saw a pair of NOS pistons from the early 70s and instead of the old style piston pin lock ring listed on Ebay this morning. The lock ring was the newer modern style retainer ring with holes for the pliers (snap ring pliers).

So, I didn't know this, but Harley indeed switched over to the newer style retainer ring for the 45 piston pin lock ring.

H-D pistons for circlips are made dramatically differently than early type with the "L" shaped retainers. The pins and locks cannot be interchanged.
