I haven't heard of anyone supplying lab seals for S series cranks - you might email Charlie at Triplecranks, he has access to plenty of suppliers. I know your heart is set on lab seals, but there are hundreds of S series bikes out there running perfectly with 40 year old rubber seals in them...

Has anyone in the UK taken over with the Chris Ritchie lab seals?

Has anyone in the UK taken over with the Chris Ritchie lab seals? Gary Clarke now does the cranks. And he has now received 15-20 (as far as I know) H2 cranks With lab seals, that needs a rebuild due to lab seals failure. I have seen a Chris Ritchie crank With my own eyes, 1500 miles, where one of the lab seals had gone to pieces. Maybe this is a H2 phenomenon due to vibrations or something, I don't know. But I know one thing: No way in h... I am gonna use lab seals in my H2. Never. |

First I've heard of this regarding Chris Ritchie seals... I believe there were issues with other designs that did not have the o-ring on the od to keep it set.
Could it be a function of installation?
I've had labs on my bike for about 20-25k now. I did take the time to make sure the labs were in the middle of the axial play before I clamped the cases together.

I have absolutely NO doubt Chris Ritchie did those cranks 100% correct. But I really doubt the lab seals are suited for a H2 crank. However, I have not heard of H1 cranks With lab seals fail. Which may lead to there are issues H2 crank vs lab seals. Vibrations??? Play?  Don't know |

Good to know! I'll never own a H2 so I'm Good to go... I guess.

I started running lab seals exclusively as soon as I found out Nev was making them, maybe 10-15 years ago. I had a brand new rubber seal go out almost immediately on a double rebuilt crank making the crank a very expensive door stop. I said never again, and went to the labs. Not sure why anyone had problems, other than bad install, or maybe a possible machining problem. I have spend years racing and track days with no problems. Maybe I just got lucky a bunch of times. But for sure, someday the rubber seals will go bad, and I never want that worry again.

You may remember my left outer seal going bad after 1 season of service from last year?!? That's a weird one for sure but it does show that failures are going to happen out of the norm.
Not to flog a dead horse Jorgen but this is the first I've heard of these seals failing. It was obvious to me why the other design that commonly would fail because there was no outer o-ring to stake it but fail to see why the H2 is any different than the H1. The bearings would have a similar axial play.
For now I'm going with theory of a poor install of the crank with the failure you saw or an anomaly.

Yup, same old arguments. Both types are the only way to go, and I'd never use anything else.  |

Maybe the lab seals John used were different than the seals used in all those cranks Gary now has repaired?
Strange thing when looking at the Ritchie crank, the lab seal had gone into many pieces. It was probably pure Luck the piston/bore was not damaged bythe metal pieces.

It's like a lot of things, many guys still won't run forged pistons because they all "seize". We all go off of what we know.....
Saying that, there was a guy recently on FB that had a new crank seize on him. It ended up he didn't center the lab seals and one was against a bearing. One would think it wouldn't be a huge deal, but the heat did seize the crank solid. It could be possible that happened and broke a lab seal apart in Chris's crank.

Correctio on my latest post:
Not 15-20 Chris Ritchie cranks, but 5. BUT Gary has repaired several other cranks lately from other crank Builders.....all of them With same lab seal failure.
