That positioning makes it very difficult to get the clip out next time you wanna.ĬM - Sounds like your wrist pin was too long - normally there will be a few thousands gap (WAG. The above type clips generally have a radiused (rounded) face and a flat face, the rounded face goes toward the pin, the flat face faces outward (toward the piston).Īn item of note I haven't seen on this thread.regardless of where you think the gap should be, don't put it at the window in the piston pin bore. Note that the term 'circlip' applies to several different configurations of clip that fits into slot. That clip was NOT a 'G' clip as Ron mentions, but worse than that, having a plier hole on each end. I've destroyed an engine when a piston clip came out. Was that due to it not being snapped in in the first place? Was YOUR pin too long? Still, I think it's mostly a matter of choice.ĬM: You said your clip was coming out. It's obviously a matter of preference, not a matter of critical import.īesides seems to me that having a gap at 12/6 'o clock would make the whole idea of mass and things moving worse because the space is what will change if the clip moves, and the space being on the axis of movement, that's where it would change the most.
WRIST PIN G CLIP INSTALLATION DERECTION MANUAL
I think proof enough of that is the different positions stated as 'right' between the manual and other builiders. Not to jump on a bandwagon, here, but I've never understood the big deal about clip position in the case of the KDX. Indeed, the clips, pins and all have to do with the piston, nothing to do with the bike.Īmen to the 'pin too long' part of what Mr. I don't know if you're asking about something specific or in particular, but, no. NO! with todays piston and clips clock position is not critical.
WRIST PIN G CLIP INSTALLATION DERECTION INSTALL
Please note that it does take some skill to install a piston pin clip and not distort it, bend it and make sure it is seated. Wiseco pistons have had there share of piston pins that have been a little to long, not allowing the last clip installed to seat into it's groove, allowing it to come loose and pop out. In turn it takes a little more skill to insert them without bending them, distorting them into the groove and getting them seated into the groove. Todays clips are about half the mass and have no flag. The reason being that these clips were very thick in diameter and they were heavy in mass. Yes in the old days of low performance engines that were starting to get into more of the high performance, still using the "G" shaped piston clips, it was always recommended to put the flag of the "G" part of the clip pointing up. I have been building all types of engines for 35 years and I can guarantee that the opening of a "C" type of piston pin clip 'clock" position does not matter PERIOD!
