Piston circlips

Thanks Bob.  I'm trying to put a used JP alongside its twin.  I just went over to Russell Motors, and Les had nothing. We looked at a Triumph clip, but they are only 1.2mm wire size...much smaller than the 1.4 I need.

I'll see if JP have an importer. And go into the garage and empty every single box I possess. My box of old pistons is relatively new...I need to find the one I kept them in before and see what's in it.

The JP I'm trying to fit is from Australia. The badly damaged one ( which is now the wrong shape) is NOS English Heppolite.  Alan...it seems like what are known as the Seger type are standardised, but wire ring types are not. The JP ones seem to be 1.4mm wire with one end turned in at a right angle. GPM are 1.4mm with both ends turned in as loops. The Triumph ones I saw yesterday are simple broken circles only 1.2mm wire and I believe the pistons have a little notch so you can get the tip of a small screwdriver beneath the wire to remove it. USA Wisco are much the same. People write "never re-use" but they don't seem to stock and sell spares.

I suspect the Seger type might work better but perhaps their main benefit is ease of fitting and removing using the correct circlip pliers. The drawback is they can more easily be permanently damaged  by being over bent. The makers say they are under most stress when being fitted, not in service.

But I'm not a circlip expert...just been reading on Seeger and Wisco and other makers' sites.

Thanks to all for the interest!

Thanks very much to all who responded. I finally found a correct pair. Meanwhile I have learnt a lot more than I expected about gudgeon pin/wrist pin circlips, snap rings, seeger clips and the wide variety of wire sizes different makers use.  For future reference....GPM wire clips can be bought new from RGM. They are 1.5mm wire size, and have both ends turned inwards. JP wire clips cannot be bought separately from pistons unless you or the dealer (Thorton) order from Australia. They are 1.4mm with one end turned in at a right angle. Rectangular section 'Seeger' clips are to a standard (DIN) and were used by Hepolite when it was Hepolite, and perhaps are used by them today. Wiseco (US) and others use wire 'snap rings' which do not have ends turned in. Their pistons have a little notch into the groove so a screwdriver tip can be used to extract the ring.  All very non standardised. The first lesson (if there is one) is: never lose a piston circlip! The second lesson is: don't bend it permanently when fitting but also when removing, just in case you need it again.
