1964 Jubilee cams

Hello there,

I am not sure what you have in mind. As far as I know all Jubilees use the same camshafts for all years from 1959 to end of production.

I have a Jubilee inlet cam sitting here on my bench and it has a number stamped on 22235 but I think this is only a casting number. On the end of the cam it is marked I 7 but this is very hard to read. As far as I know the casting number is the same on all lightweight cams and it is the number on the end of the cam which identifies it. So I(nlet) and E(xhaust) ; the number 7 means Jubilee and the number 5 means Navigator/Electra.

Therefore Jubilee cams are marked on the thrust end of the cam with the I7 or E7.

Hi,

I think there must be a difference as on the NOC shop there are two types of Jubilee camshaft:-

Early non thrust plug type.

Thrust plug type.

I have no idea of the difference.

The man who would know is Andy Sochanik, I know he does not always have the time to read the forum so I will email him with the question.

Regards

Tony

Hi James,

Both answer given so far are correct.

Very early engines used cams without thrust springs at the opposite end the the cam gear. They are obvious by nothaving a hollow to accept the springs. Beware of using the later cams with thrust springs & plungers on earlier engines, unless you also have the metal thrust plate under the camshaft bush at the far end!

To identify the cams..

Inlet Jubilee has I7 stamped on end away from gear

Exhaust Jubilee has E7 stamped on end away from gear

Inlet Navigator has I5 stamped on end away from gear

Exhaust Navigator has E5 stamped on end away from gear

Electra has Navigator cams fitted as standard (TBC)
