Pulley

Featured Posts

Do you have a part no. for the 'Diesel' pulley ?

 

The part number for a BMC 1.5 diesel pulley is 12H 253 or 12H 1460 according to the BMC parts book I've got .Both numbers are listed as alternatives.

Did you find one?

I had to use calcutt in the end and that was for one off of another engine. All up and running again now.

If that isn't the most helpful post I've ever seen, I don't remember what the better ones were! I don't have a BMC engine, but I might go and buy one just to ask questions about it now! Nice one, Richard, have a greenie. smile.png

 

Indeed.

I've just bought a spare pulley for my MG ( plan to fit a trigger wheel to it ). When it arrives I'll measure it and post the dimensions in case someone else needs a replacement.

But how are you going to test the frequency of torsional oscillation the rubber member is designed to damp?

 

I know that if its is not correct it can snap the crankshaft and the MG has a petrol engine not diesel so the frequency MIGHT be different. I would say part numbers or input from whoever designed them is the only way to really know if they will do the job.

 

I am not saying there is a difference or even if there is that difference would snap a crank but is it worth the risk? Richard has shown how the split boss can be overcome.

If its running at the same speed, with the same no of cylinders, the firing frequency will of cause be the same.

 

A petrol engine will also have a less harsh firing force, however, if its designed to have a damper removing it is obviously always a risk to an extent.
