They NEVER mix colours on one pin but different colours on different pins is common.Non of the numbers on the shells mean anything apart from production code, last thing done in production is measure thickness to 0.001mm and colour code them
What journal was the green shell on Ted?Must be either 2 or 4.
"I'm learning here I have never encountered a car with such complications as different coded journals on the same crank - wonder why STD didn't mean just that with oversize being +0.1 or whatever."It is, in essence, a view of the lengths they went to in production tolerancing. Ordinarily in most process as it advances the tolerances are accumilative (unless by happy accident one error cancels another) with the accepted machine accuracy and repeatability available producing the components being recognized, the range of 5 different shell dimensions is planned to compensate for that process capability. It effectively pulls all of that production line tolerance back to as close to zero that they could get it.In terms of "old money" a BMC A series built with en40b crank fully balanced, ground, nitrided, micro polished to perfection, with rods balanced end to end and rod to rod, etc etc, effectively the best hand finished blue printing only gets close to what these engines came off the production line as absolute standard. With near 100bhp/litre and usually ten thousand rpm ceiling to go with it, that really shows just how good this design and production was, that's in mid to late sixties and early seventies, there's nothing that came close to them.
Lol, Ted the numbers on the rods don’t refer to the cylinders they are fitted to, it’s how Honda identified the journal size so further down the production line whoever was assembling the engine just needed to check those markings and the letters on the crankshaft to know what colour to fit. It sounds complicated but once you get your head around it it’s really very easy and logical
Ted, I strongly suggest that you buy a Clymer or Haynes manual for your bike and read the section on measuring and selection of bearing shells. It will save you having to ask so many questions on here. These engines and tolerances are nothing like old car engines. The colour codes are selected for a brand new engine assembly with no wear on the journals.If there is any wear on the journals now then the codes probably don't apply any more. The journals need to be measured very accurately, as has already been mentioned.
Ted, I didn't mean to criticise you, just pointing you in the direction of the knowledge that is necessary to get these engines right.The manual section on bearing codes clearly explains the colours/sizes available. It helps me to have prior knowledge on things like that before I get into the guts of the motor.
