I'm not an engine builder by profession, but I am no novice in engine building. I did had some difficulty with the first set , until I got the hang of it, in placing the circlips on the set of pistons I used for my last engine built. I did not use the stopper on the other side, just a small screwdriver and then an allen key to push the end of the circlip in place. When all in place I did a check on them with a small pipe the size/diametrer of the circlip.

Very nice video. Clear and concise with well-lit video.

Replacing simple but tiny Circlips on a Centerhousing of a MHI-TD05 Turbo can be frustrating too. But when its done you can be proud of yourself with a happiness moment.

I feel like every time you install a tricky circlip there should be a wee glass of celebratory whisky that appears before your eyes. It could also come sooner those times when struggling a bit, I wouldn't complain - Taz.

Thank you! your video actually help me a lot~!

I use a popsicle stick to help install circlip as it wont scratch anything.

Is there a specific way the opening of the Clip should remain once’s installed in the groove?For example g opening part facing up?

If you orders Wiseco piston: goodluck getting that pin in with out bending it

Kram Loxx are awesome, i would use those for circlips. So easy to get in imo and they won't move in a circular motion.

These wire locks will not rotate either ;) - Taz.

I use a slightly different technique, using a fine flat screwdriver in the notch to ease the clip into the bore and groove. However one does it, take care, peoples, as it is easy to make a blood donation or have the clip spring out and get lost. Oh, and don't apply more force than needed - if you go beyond the elastic limit and deform the clip it WILL loosen, drop out and destroy the bore, if not the whole engine. Forgot, I use a bit of W&D paper to remove the sharp edges of the screwdriver blade to reduce the chance of marking the piston - might be a bit anal, admittedly. Forgot II, you can pick the jewelers' screwdrivers up at your local electronics store - down here that would be Jaycar.

Awesome? You obviously don't know me very well ;-) If you have an XL I would be pleased to wear it. Just trying to add some discussion points and bits and pieces I'd picked up here and there - sometimes my experiences, sometimes from others. Sometimes I'm wrong and I hope you, and the other respondents, can keep things on the straight and narrow. The bottom line being we all want our engines, regardless of spec', to hold together and perform as best they can.

The open part of the wire lock should be either in the 12 or 6 o'clock position. If it's in the 9 or 3 o'clock position the clip could be compressed from the reciprocating forces of the piston.

Shaun Blair in theory it wouldn't matter, as the circlip is held within a groove, force on any side of it would have the same effect

@shconer

6 жыл бұрын

I disagree and here's why. The circlip is compressed into the piston and the spring tension of the circlip is what keeps it in the groove. If the circlips gap is positioned 90 degrees relative to piston travel, the clips own weight when subjected to the extreme forces exerted on the piston will work against the circlips spring tension. Without this tension, it is possible for the clip to come out of the groove. Your assertion that a force from any direction on the circlip is inconsequential is incorrect. If this where true then it would be impossible to remove the clip and that's obviously not the case. Furthermore, while it may take a rather extreme piston acceleration to unload the circlip tension enough to release the circlip from the groove, a more likely outcome would be that over time the circlip becomes fatigued by constant bending and breaks.

You're overthinking it - while you are technically correct, if it was an issue the manufacturers would specify the location. no reason not to do it like that, though, if it is a concern.

Not something I was aware of - thanks for that, something to bear in mind for the next time. Well worth a thumbs up. [edit] FWIW, the piston acc'n is greater at around TDC than BTC and the shorter the rod to stroke ratio*, the greater the difference. So, I would suggest the gap be to the bottom of the piston if that is a concern. *For true sinusoidal piston travel an infinite length conecting rod would need to be used.

hi what is the name of moly oil that u use? thanks

Good Video Because it essential that the wire lock groove is not lubricated prior to insertion of the lock...I wish you had included your suggested steps for lube. Good effort overall Would love to see more information on Proper Fueling with Direct Injection without requiring supplemental port injection.

Attila Pap It's a lot harder to install a wire lock with out the wrist pin as backer so you put the clip in, in a second, and it holds it.

Give it a go and see Attila. If you find that easier then it's the right way for you but we do think this method is going to cause you less frustration by removing the chance of pushing the circlip right through before it is seated correctly - Taz.

I would expect it to be a concern that the bore in the piston gets scratched, or otherwise damaged, which might compromise the life of the engine?

Was doing some checking and came across a motorcycle engine tool on the Accu-products site called the "C-Clipper four stroke installation tool" for these "c" clip retainers. It looks like it could be just the thing, but is limited in gudgeon/piston/wrist pin diameters. Anyone heard of them or even tried them? [edit] Seems to be made by Bux Tools - they have a video on YT illustrating using the tool - kzread.info/dash/bejne/npt2lLmogcXaj7Q.html

I cannot stress this enough, your technique DOES NOT WORK without scratching the everliving hell out of a 450cc piston. DO NOT USE A SCREWDRIVER, EVER! The bulldog clip technique is nice, but I found it much easier to put the open end in first, THEN push the other end in with something soft, like a nylon mallet.

You should be fearful of a man who installs a wrist pin circlip without safety googles on lol
