Thanks for the info Guy and yes I will have a closer look but the belt is nice and tight with no slippage.

Had a look at the adjuster assembly and I have 15mm give in the belt which is about right, to have any less would put pressure on the bearings.

Hi Paul
In my experience I would say the belt is too narrow and not driving on the flanks but on its inner face and it will be prone to slipping. The outside of the belt should be nearly flush with edge of pulley. Take a photo of crank pulley so we can see how belt sits. I think this is what is causing your problem, belt slip.

Default belts

I discovered that modern V belts don't always match well with the older type pullies. There is a standard for V belts that's been around many years , the "B" type is commonly seen in older machinery.

My series 1 Land Rover is always a problem, finding the correct belt . I have fitted a modern belt that functions but somehow the modern belts don't quite fit correctly, the new belt makes a squeeling sound , as if something is rubbing . I believe the series 1 club in the UK had a special batch of belts made .

Yes I agree with the comments, that C8 belt isn't sitting as it should be , the profile is too narrow or the "v" angle isn't correct.

Hi Mike,
You are correct on the belt V-angles. The standard A,B,C etc used on machinery and general engineering is still around and a lot of vehicle and engine makers used them, but, there was another British Standard for Automotive belts with a slightly different angle, no longer available now, I find that Austin, Morris and Rootes group engines were on this standard, and probably many others. The replacement belts are a compromise, and usually touch on outer edge, but will bed in without issues.
Looking at Paul's photo, as he was unaware that the pump pulley was adjustable, then I assume it is still set for an old belt, and it is the crank pulley that will define that. It would be impossible to fit the correct width belt without opening up the top pulley first, so my reckoning is the pump and fan was not turning fast enough as the belt was driving on the inner circumference and losing grip at times. The new belt needs to fit the crank pulley and likely will stand proud by about a millimetre or so, not sure if it would be a B or a C section.

Lots of info to take in and hopefully the picture has uploaded, what kind of fan-belt do you suggest Richard? Difficult to find old belts these days, I will take it off tomorrow after the Anzac service and will go ahead with replacing the individual bits as they are worn. Spring I should have an answer on Wednesday for replacement.

Paul, have you checked for a head gasket leak or cracks as a possibility for blowing the water out?

Hi Paul.
You need to determine the width of the top of the Vee on the crankshaft pulley. If approx. 16mm, then try a B section belt, but if 22mm then use a C section belt. The supplier should be familiar with B and C section belts as it is an International designation. As for length, you will need to open up your pump pulley and when belt is fitted the sheaves are adjusted up and engine turned over a few times, then recheck adjustment. When the belt reached the top of the vee on pump pulley it is near end of adjustment.

From what I have read here you fitted the belt without opening the adjustable pulley, is that is correct?

A Morris C8 owner might know the replacement belt number.

This might be of interest:

Richard and Lynn thanks for the info and I replaced the head gasket as there was a problem with "water" ingestion due to no4 spark plug being very loose when I first got the truck, on stripping the head off I found two gaskets fitted but I have replaced them with a copper gasket and there is no water in the oil or blowing out the exhaust so all seems good. When I replaced the water pump and belt I didn't realise where the adjustment was so even though it was a tight fit I got the belt on, I will replace the belt with your spec's Richard and have an auto spares place I use that employs people over 21. The coolant blows out on reaching running temp so I believe the problem to be a combination of all the things you guy's have mentioned so as I have said spring, filler funnel and threaded lock ring will be replaced with new and I will search out a replacement belt.
Regards and will keep you all posted
Paul

Thanks Richard and it looks like a C section belt I need, by the looks of the belt removed it has been rubbing on the sides as you say and the length can be longer to take up the adjustment, will source another tomorrow.

She is correct in that Dave and we have an Auto pro store that only employs people over 25 so you have half a chance, the one thing I hate is when they say "whats it off" so you haven't connected, I will probably get roasted alive and hung drawn and quartered for saying when we go to the check-out at the supermarket I always choose the ugly check out chick but they are better than the eye candy ones. Shouldn't have said it but there it is.
