Ferodo fan belt number.
Anyone know the Ferodo fan belt number for a 1962 948cc Minor please?
Re: Ferodo fan belt number.
Standard dynamo or converted to alternator? The belts are slightly different.

Re: Ferodo fan belt number.
That appears to be Series II only which had a thicker belt. There seems to be some difference between the 948 and 1098 fan belts, but I'm not sure what.

Re: Ferodo fan belt number.
V500 is NOT the right belt for the 1000. It is indeed the thick belt for the Series II.
The correct belt for a 948 engine appears to be Unipart GFB102.
Interestingly, the Mintex belt WFT 319 is listed to fit a 1098 Minor engine from 1963, but a 948 Minor is not listed in spite of said belt's suitability for an A35 and A40 948. But WFT 319 is also listed for a 5 cwt. Minor van from 1957.
Bizarre. I am still no closer to a definite answer if the 948 and 1098 belts differ. There's probably not much in it, but there could be an important subtle difference in V angle or belt length.

Re: Ferodo fan belt number.
Are the 1098blocks a slightly different depth, or just a larger bore.JOWETTJAVELIN wrote: ↑Sun Oct 25, 2020 9:21 pm That appears to be Series II only which had a thicker belt. There seems to be some difference between the 948 and 1098 fan belts, but I'm not sure what.
That's the only reason I can think of for there to be a different size.
A different depth/height to the block would chance the overall size of the triangle formed between the 3 pulley centres.
But there again, any difference is probably so small the adjustment to tighten the belt would likely cope with it

Re: Ferodo fan belt number.
Part way through Series III production, around 1960 a higher output dynamo was introduced. It has a smaller pulley to run at a higher RPM. Thus the belt is a little shorter. They higher output dynamo body has a step down in diameter and the older one has a straight cylindrical body.

Re: Ferodo fan belt number.
There is a limit to the rpm a dynamo can continually run at.
If the dynamo is run at too high a revs the commutator can fly to pieces.
To overcome the problem BMC/BL fitted a larger diameter pulley to reduce the rotational forces acting on the commutator so keeping it all together.
