Piston clips?

[koba]

Where is a good place to get 'em?

When I was doing lots of work on the streetstock bikes I was going to the local honda dealer and buying individually wraped clips for a CR125 @ $2 Each.

The bike shops I have tried have no way of looking them up by size so if I do it that way I need to know what bike in their brand has the same size clip as the one I wa

So:

1) Is there a better place than a bikeshop?

2) What Yamaha uses the same clips as a Honda MB100, preferably without the wee tails? (Still havn't measured the MB ones yet, Must do ASAP)

If memory serves the last 2 digits of the Yamaha part no are the circlip size..

In ChCh anyway Proturn Eng carry a pretty good range of piston circlips. He's agent for Arias pistons so look for someone in your area in the automotive performance field.
FWIW - $2 each is pretty cheap insurance and you'll stuggle to find anything cheaper.

True.

Yeah, I've seen the results of one coming out before...

When I went to the local engine re-conditioners the guy just handed me a big box of assorted clips and said "Look through that".
The box had almost no wire ones in it.

I've bought MB100 circlips by the "bag of 10" from the bike shop. I'm using KT100 pistons now and have used KT clips and the MB clips without dramas. suggestion - go to your local kart shop, they will have clips in stock and pretty cheap as well usually.
I always destroy circlips the moment i take them out so I can't be tempted later to reuse them.

He's got me to do that for him. Before he even gets the piston out sometimes.... :whistle:

Are you allowed to be using race parts in your motor you naughty man??:shutup:

[F5 Dave]

Well Pistons are no restrictions, that must continue to the clips. What road bike were those Lonchin engines used in again?:innocent:


Hels, you made me larf!

Chur, Shall look into that.

Damn, foiled - I will never defeat you without the KT100 clips!!

She makes me... :shit: nevermind.

[gatch]

Are these circlips not a standard size ?

[marsheng]

I've been re-using circlips for over 30 years. Never had one come out. It depends how you take them out and how you put them in as to whether they stay in or not.

If you have to bend them say 10% to put them in and then bend them 10% to get them out, there will be no damage to the steel structure.

You don't take an end and yank it out, you take one end and slip it out the groove, you then take a needle nose pliers and turn the clip through 180 degrees to remove it.

[bucketracer]

Yep..... I have seen TeeZee re-use circlips too, never heard of a problem.

[F5 Dave]

I've seen the results of a small end mismatch pushing the pin sideways popping the pin out & rooting the barrel from any sort of reasonable repair.

Yes that Young chap did have some interesting experiments with elasticity & steel is a wonder material, if kept within it's boundaries, I just don't think it's worth the risk for a couple of bucks.

Never heard of the problem? Not read Bells book then?

[jasonu]

I agree with Trustrum. What a bunch of tight arses. Crowbar ya wallet open and pay the couple of bucks for new ones. Good insurance I say!!!

I have a couple of bucks, please send ten Wiseco CS16 circlips.........

[F5 Dave]

yeah Wiseco ones are expensive for bent wire, but my last ones for my 5hundy weren't more than $4ea.

[marsheng]

The price is not the factor. The ones I have just taken out,( provided they are not damaged) have proved to be up to the job. I can't guarantee new ones till I have done several hours at full taps. Sound strange, I used to fly Microlights and the book said to change plugs every 50 hours. That was till one day, I put a new set of NGK in and found one to be faulty. Ever since then I have trusted my own used plugs over new ones, provided they were in good condition and only changed when they looked tired. PS I wasn't the only one experiencing these problems.

Has anyone used aluminim bullets instead of circlips before?

If you mean alloy plugs that are fitted to the ends of the piston pin. Then yes, back in the old days they were sometimes used in slow reving engines, still wore groves in the cylinder though, and not to good with 2-stroke ports.

Still seen in aircraft engines like this 2,500 rpm Lycoming, check page two........ http://www.lycoming.textron.com/support/publications/service-instructions/pdfs/SI1267D.pdf

[Ocean1]

Far more likely to find a faulty new circlip than one you've removed (without fucking it). They're just spring steel guys, they don't actually wear out y'know.

Used to make teflon buttons for some builds, where circlips were known to be a problem at high revs. Really only good for engines you're stripping fairly regularly.

[ellipsis]

....Marsheng and Ocean1 have the answer....

[Henk]

I'm ashamed to admit that in my young stupid and impoverished days when I was rebuilding RD engines out of the box of bits in the shed with no new components used at all I did on ocasion make my own piston circlips by cutting up key rings, dodgy as hell in hindsight but never had one fail.

[F5 Dave]

aluminium bullets? nah that's silver bullets if you want to kill the vampire. Not sure what you'd use Aluminium bullets to kill, perhaps something soft like a charted accountant.

I thought silver bullets kill werewolves, maybe they kill vampires too, Very clever things if they can multi task....................just like women....................

[F5 Dave]

oh yeah, yer probably right. Despite all these silly vampire programs on the telly I'm not up to play with the mythology, I think I'd rather watch another cooking program. Actually I'd rather turn the telly off.

Women only need to multitask because they can't organise
