Hi, One thing to note is their is not much contact between a belt and the driven pully on the crank, two belts double the contact surface. I think my belt had been slipping before failure, quite an inertia on that fan and windage produced from the blades. When I eventually change out this engine for a wartime flattie it will be twin belts for sure. On closer examination it was the wrong size belt in width.
kev.

Not knowing where you obtain your replacement belts from, but worth checking the angles of the pulley grooves on your engine in comparison to the belts used. Belts available in UK are usually the British Standard sizes with A, B and C widths, but these do not always correspond with pulleys on older engines, as there was a British Standard for Automotive belts at one time and the vee angle was slightly different, to use a B or C in these old pulleys, they tend to ride high and do not make a lot of gripping contact on the belt flanks.

Kevin. I think you will find these old fords used a special profile belt (as Richard has aluded to) I have an original belt here, Autolite 7RA 8620C the belt width is 17mm wide, but the depth is 13mm (a B section is 11mm)
I think this will mean the angles of the side of the belts are different. To do it right, you might have to go to the trouble of getting belts from a Ford dealer (e.g. Vanpelts in the U.S)

Did the belts on a mates carrier a few months ago. Didn't have any trouble getting them here in little old New Zealand.

my experience with this is to check the insides of the pulleys very very carefully the slightest burr or bit off crap and you will eat through belts..... there is always the issue with over tension but knowing how anal (meant as compliment mate) you are Kev i doubt you would have done this

My carrier chewed up a fan belt last summer, and with the Chevy 350 setup there is only the one. Noticed the temperature guage climbing and shut her down in time to avoid damage. They do get very hot very quick as there is little natural airflow over the radiator.
