The progression of an H22

I agree if you use the correct cleareance bearing the is the most important thing. I know that most places that sell ACL or other aftermarket bearing sell the Standard sets to everyone. Alot of people just throw them in everything. I have seen big name places use standard bearings for everything they build.

Rumor has it that there is something very special about gsr/itr bearing composition and their applications, not sure if that was the case with the other oems.

I like to study the mechanical failuers. I have had great luck with Royal purple or Moblie 1 10-30 and we always use Honda Bearings.

Seems the bearing is just disintegrated. Nothing is disassembled so I havent looked at anything else closely. ACL STD bearings, 55mm mains The motor was broken in with shit 5w-30 from the local parts store, $1.49 a qt I think. Filled, started...run for 10 minutes and drained and new oil filter. Then it was immediately put on the dyno and tuned to 10psi. Drove around easy for a while working out other bugs. 2 passes at the track, oil changed again and then put in the Eneos 0W-50 and the K&N Oil Filter...couple more passes on the dyno and 3 at the track...gone

Motor just came out of the car tonight so it will probably come apart soon...I have another project that has my motivation at the moment so this might sit for a bit...but I will be learning how to and sizing my own bearings from now on. Yeah...

sorry to hear about that chris. Could you post pictures of the bearing once you get it torn down? I'd be interested in looking at the wear pattern.

I definitely will...but I got busy with this today, so the H might move down in priority for a little bit

#4 Spun, #1 was about to spin but didnt. #4 Rod has a LOT of wrist pin play for some reason...not sure what that's about. Bearing Pics: (click on the image for large version) Bearings #1 - #4 all lined up nice and pretty

Bearing #4

Bearing #3

Bearing #2

Bearing #1

#1 - Weird Gap thing going on here

Mains all looked fine...some of the original coating was on each of the mains.

are those pits in the #3 bearing? hard to tell from the pictures. what kind and weight oil do you use? They all look a bit too shiny, suggesting that oiling/heat was a problem. But it doesnt make sense that your mains are perfect.

No pits in the bearings...#1/#4 are \"smashed\" I'd say...#2/#3 look fine except for some grooves where bearing material probably got in and wore away a groove. The smashing is at an angle though which is odd to me...why there would be more pressure on one side of the bearing than the other, unless maybe the crank is bent/warped...i unno. Taking the head off today I think.

happen to check the plugs for inaudible det? makes a little sense to me that the sides have more wear since the rod/crank angle at peak cylinder pressure is not on top and bottom of the bearing, but more so to the sides of the bearing.

Plugs read clean on the dyno and I was completely conservative on the timing...plugs checked after the first two runs where everything was fine read fine as well. I dont have any logs of the runs unfortunately because the power plug on my wideband was loose which would cause eCtune to stumble and quit datalogging right at the launch. That got annoying...I need to find a better power cable I guess. BTW, the oil was Eneos 0W-50 if I didnt mention that before.

timing, bearing clearance or lubrication

i remember the day that dog kicked his ball under the cabinet and layed down for about 15 min lookin at it...with the multi-colored eyes

Got a squeeky clean A4 crank from Reid @ Kaizenspeed (thanks for the hook-up) and the Pauter rods are being sent off tomorrow to be reconditioned at Pauter tomorrow
