1977 400F2 first restore project
McCabe-Thiele (Ted):
Camshaft top cover is looking good Steve,
I know it's not a race but I'm in Groundhog Day mode awaiting my upper crankcase return from having the Helicoils done on the cam tensioner arm.
It will be next week before the Zinc plated bolts are done for the crankcase bolts.
I am looking forward to assembling the crankcase halves (again) and fitting the pistons & barrels.
It's all about the build as they say on American Chopper!

Serviced the oil pump today with new O Rings from Julie. I don't know if the dots on the pump rotors should both be facing the same way up, but they weren't. Having stripped, cleaned and measured for wear I put it back together the same way as it was before I took it apart. General condition was excellent but certainly some wear on the O Rings.

Nurse Julie:
Both dots should be facing you, one dot opposite the other, so you get the Gerotor in the correct position. But, yours will already be worn in with the dot not showing, so agree, put it back as it was.

Thanks Julie, I was a bit worried about which way to go, as well as confused by the Haynes gibberish, but I figure that the dots are just there to aid getting the drive spindle in easily. I can't see it matters too much provided it all goes back together and turns freely when tightened up, which it does.

Have started rebuilding the engine and looking at the main and big ends at the moment. On disassembly I thought the main and big end shells looked good to re-use, however...Fitted No 1 conrod dry and there is visible movement when "waggling" the rod, so much so that I wouldn't even bother with plastigauge. I was really hoping to dodge this bullet! Not on grounds of cost but from reading many baffling posts on shell colours, crank markings, case lettering, unmeasurable journals etc etc. However it looks like I'm stuck with the problem so here goes. I'll stick with the big end shells for a start. There are no visible colours on any of them, where do I go from here?
Pictures of crank showing all visible markings.
Edit, added a close up of a big end shell to show the lack of paint marking. The brown colour that is there wipes off and is the same colour as all of the internals that were covered in brown grime.
