With the work I was asked to do all done on this engine, this is just a short recap on what that entailed and some of the new components which were fitted.
G'day Paul, the owner will be pleased with great job you have done, l myself would have had you build the whole motor for pease of mind, cheers mate, Neil 🤠.
Great work as ever The theory behind leaving the seals on the bearings is basically if the bearing has a design like of say 100,000 miles thats how long its designed to last with the factory sealed lubricant If you open it up to the gearbox oil there's a possibility of micro debris suspended in the oil and entering the bearing and shortening its life That's the theory anyway I guess if you change the gearbox oil regularly and don't see any debris or sludge in the bottom the bearing will last longer?
I still want to know how they assembled these engines at BSA? Now I've worked with limits and fits from the Zeus book data but to hit 0.0015" to 0.003" dia and less than 0.002" endfloat is tight for production assembly.
Looks like the owner went with current advice and upgraded the con rods too...Great job all round. What's your preferences for a crankcase sealant Paul please?
@markmetzger5430 I've seen Allen millyard use Permatex Ultra Grey on his Norton nemesis rebuild series and Frank at vintage British motorcycle repair uses Permatex anaerobic 51813
Nice job. A timing side roller conversion is nice but not always necessary if the bush is well engineered and an uprated oil pump. Are those Carillo rods?
