need clips or spirals??????? any thoughts..and where can you buy without having to buy wrist pins...

??????????????????????

It depends on what the piston is designed for. If it uses Circlips, the whole is rounder and wider. If its cut for spirolocks, the hole is very square. I wouldn't use spiro's where circlips go and vice versa, they will probably fall out and make one hell of a mess.

Duece, I've had no issues re-using clips in the past. Many piston swaps and no failures

Agree Ken. I would just expand them a little, to give them more SNAP, :nod:

I wouldn't.. No need, they are spring material, you bend it out of shape you risk losing the rate...

I dropped my GLHS engine off for freashening and when he pulled the pistons (Weisco) the CirClip was loose and slopped around :eek: (all of them!). It looks like they had lost all "springyness". Don't know why or what happened as these came in the kit direct from Weisco. It now has Spirolocks all around.

I got lucky (again...)

No kidding, go buy a lottery ticket. I have seen the damage a loose circlip does, its not pretty, :(

As Ken said, I've reused the stock Mahle circlips without any problems. It's almost scary that the Wiseco circlips didn't hold up as they were intended. In that case, I think I'd rather re-use existing clips that have been known to work (with the correct piston of course).

As with all these pistons sh!t happens. Look at the stockers. A few had the problem, and yes it wreaks havoc on the bores... I've seen it on 1 car total. I've had a lot of engines apart. Steve's experience is the 1st I've heard with the wiseco clips.

I do know the pistons take abuse well...

thanks so much guys........

i now have 9 used clips from 2.2 .........and one from a 2.5....it seems thicker???????

only needed 8 2.2 clips :) so its building time.........

once i get this short block built on the stand.......well its gonna be guys like you who helped me.....

THANKS

I've heard there is a right and wrong way to install stock cir-clips---the clip is shaped like a horse shoe and the open end should be facing straight up or down--as engine RPM increases more centrifical force is applied to clip and if facing to side of engine enough force could be applied to close clip enough that it un-seats itself and is then only held in by cyl. wall which usually ruins engine--if installed up and down force is not applied nearly as much to open end arms--we even staked the cir-clip bore so rotation of clip could not take place--bobr19

YOU GET AN A+ :)

QUOTE FROM A 4 STROKE BUILD MANUAL ON CRF250R HONDA 13,000 RPM MOTOR.

"The open ends of the clip should face either up or down, but not to the opening in the piston".

I just put them in, never paid attention to where the open end is, even on my race bikes, :thumb:

you mean, you put spirolocks in the wisecos and they worked?

I wouldn't.. No need, they are spring material, you bend it out of shape you risk losing the rate...

Over compressing them (ie: using more than what's needed to remove them) makes them lose their spring and a possible failure.

Make sure you compress them JUST enough to get them out.

If the groove isn't square cut, you can't use spirolocks, they won't seat and might come out, and if you use circlips where spirolocks go, again, they won't seat and might come out.
