1966 V8 Saloon Generator Belt Size

Post by Clive » Sat Nov 10, 2018 9:01 pm


Does anybody know the original belt dimensions for the fan/generator belt on a V8 Saloon?

The one I took off was an old Dayton 9.5mm x 605mm. The replacement from SNG is 10mm x 617mm (Dayton 10A0617C) and too long - I have the generator set at the maximum adjustment to get correct tension. The old one was in the middle of the adjustment range.

The widths also look to be a bit narrow, although they do not bottom out on the pulleys. I see Dayton sell a 11mm x 610mm x 36 degrees, but I don't know if the V angle is correct (Dayton Part 15240).

I would appreciate knowing what belts others have found suitable.

After ordering a dynamo belt from various places and none of them fitting properly, I measured the width of the pulley and and the length it should be and went to my local motor factors and they looked in their belt catalogue and found me the correct belt just from the sizes I gave them. It fitted perfectly. Worth a try.

Hello Clive,

Further to John's comment, if you take your belt to a motor factor such as EBC they have a the correct tool for measuring the belt. From there they can supply you with the correct dimensions.

Normally a Gates belt will be ideal for your requirement. The belt width should be 9.5mm / 10mm (11mm is too wide) and the length of 605mm is a readily made belt.

Gates make excellent cogged belts so I believe this would be the way forward.

Of interest another good make is Dayco - and for less than £5 this belt may well assist your quest:

Good luck.

Hi From down under,
I recently replaced my 1964 saloon generator belt with a Gates brand belt part no. 13A 0620. The adjustment is about halfway up the slot.
When I purchased my Daimler about 3 years ago it came with a genuine Jaguar generator belt and some other bits in the boote. Driving it home a distance of about 200km. the generator light came on and on inspection I found the generator belt had failed so I completed the drive home on the battery. At home I fitted the Jaguar belt a bit of a mission getting the fan blades off the pulley. This Jaguar belt has also failed hence the universal belt now fitted.
