Re: Fitting Allen screws to rocker box on B50.

I fitted UNF Helicoil thread inserts to the cylinder head of my B44 during restoration, counter-boring the rocker box to accept the Allen screw heads to a near flush finish. The arrangement has been oil-tight and in my opinion, gives a more pleasing appearance than studs and nuts, together with the ...

Hello Francois,

Best practice is to fine-tune the fully advanced timing position using a strobe timing light, once these marks have been used to get the engine running.

Re: Final Drive Sprocket

I've been going over a fix for this persistent oil leak in my mind. I am now wondering if it could be caused by the primary backplate oil seal (40-0243) being distorted by the felt washer. Could it be that an excessively proud felt washer ( i.e. too thick) is making the oil seal lip flare outward, a...

Re: Replacing gear box main oil seal

Yes, the seal is 40-0243 and also known by the (Triumph) number 70-3833. You may also need the felt washer 90-6074 which sits in front of the sprocket securing nut.

Re: Final Drive Sprocket

Hello Ian,

I'm pretty certain that it is primary oil, being thin and containing what looks like clutch plate debris ( blackish). It only weeps down the back of the casing directly after a run. All is OK during storage on prop stand, with no further leakage.
