Featured Posts

Hello, my timing belt snapped and needs replacing, though it broke right on the part number to google it for a replacement.

could anybody suggest where I may be able to contact whom would know the correct part for this engine? 
I have already tried ASAP solutions and force 4 chandlery.

 

thank you in advance

Do you mean alternator belt? The 1.5 and most boat engines use a timing chain or gears. If it is the timing chain that has snapped, you can expect a lot of engine damage.

 

You can measure the length on the broken belt, then you only need to get the width and profile correct.

Hi Tony, yes, you are correct, it is the belt for the alternator and water pump config, not a chain.

BMC engines have timing chains. They stretch but do not snap

I had a Vauxhall Zafira on which the timing chain snapped. In the Loire Valley, just as we were about to set off to drive to the ferry home on the last day of a holiday. Thank heaven for AA Five Star insurance, who got us and the car back home. But the car turned out to be not economically repairable.

I don't know about the Zafira but BMC B series have substantial chains. With regular oil changes they will last as long as other parts of the engine.

Take the old belt to any motor factors. The number on the outside relates to its length in cm. They will be able to match it and at a price that is a lot less than one with a marine mark up. Make sure it is a notched one. I can see some of the part number in a picture of the broken bit, but there should be an undamaged section of belt with the number on too. They can match length, width and section type.

And if they don't have an exact match for the belt length (they don't usually have a full range in 10mm increments but different manufacturers may have different steps between sizes) pick the closest length with consideration for your setup - if the broken belt still had plenty of adjustment left on the quadrant before it broke then a shorter one may be difficult to get over the pulleys even when the adjustment is at minimum, on the other hand if the adjuster was always 3/4 out then a slightly longer belt may not tension properly.

Or try an online supplier such as https://www.bearingboys.co.uk/AX-Cogged-Belts-13mm-x-8mm-1519-c (other suppliers are available), who will probably have a larger selection than your local motor factor.

Don't try the likes of Halfords, who can only supply a belt if you can tell them which make and model of car it is for.

Yes, and telling them its off a A60 taxi or a diesel J4 will still have them stummed.

Halfords have moved on. They want a registration number before they can help you nowadays. In most cases it will then take them 24 hours to order it in.

 

The air cooled beetles were still built in Mexico a long time after the German factory moved on to more modern engineering.

It is so they can employ a spotty 17 year old on the parts desk, instead of someone with years of experience who will need paying more. Again, having the parts stored centrally and sent to the outlet only when ordered saves cash. It works for 99% of enquiries, but not for the last 1%, which will include boaters trying to find an equivalent part for their diesel engine. The parts database cross referenced to registration number is a brilliant idea, helping you get the right part for a conventional car, but as soon as a customer needs something a little unusual the 17 year old is at a loss, acne, or no. Better to find a place that still employs the knowledgable. They still exist.

And who have a plethora of catalogues and can read them so they can cross-reference and find parts for the odd uns.
