Hi

My primary chain case has a drain plug, is this not normal?

Regards Mick

Hi Lee

Can't really help with the level question - my FH is still under restoration. When I get to the point of filling the chain case I plan to fill it until the chain is just dipping, (around 1/8"), into the oil based on my experience with other marques.

Hi Lee

Yes mine does the same, I just nip it up with a ring spanner whilst applying downward pressure - it doesn't need to be tight, just nipped to remove any slack.

Hi Roger / Lee As I said, once the primary chain tension is set and the gearbox mounting studs tightened the adjuster has no function, the torque on the mounting studs maintains the position of the gearbox and therefore primary chain adjustment. Nipping the eye bolt nut in the tighten direction safe...

Hi

The position of the selector drum is not critical, it can be set in any gear or neutral for assembly - but as a guide the photo below shows the selector in the neutral position.

Hi

On the stand my rear wheel is around 2" off of the ground, your modified feet may be responsible for this discrepancy or the stops at the top of the legs, (adjacent to the pivots), may be worn on your stand and/or frame.

Hi That nut and eye bolt assembly moves the gearbox fore and aft to adjust the tension of the primary chain, make sure the secondary chain is slack during and adjusted after the primary is set. Before adjusting the primary chain you need to slacken the gearbox to plate attachments in order that the ...

I had drained the oil and put it back in the tank Hi I don't think you can drain the chamber surrounding the oil pump unless you remove the timing cover and my estimation is that it will hold around 150ml - 200ml. My engine had not run since 1995 and it had not wet sumped - you need to drain the su...

Most likely it has “Wet sumped” , Hi Not necessarily, the area below the oil pump is not scavenged, it's level is determined by the port joining it's chamber to the crank case, (arrowed in the photo). as I understand the system there will always be oil in this area and to this level, (this is how t...

Hi If you look at the gasket between the outer and inner timing cover you will see there are three distinct chambers: The upper forward one should only have grease in it which lubricates the dynamo drive. The upper rear may be wet with engine oil but any fluid should drain from here into the sump. T...
