[Healeys] Stripped Water Pump Stud - now fan belt size

...if that's a 45 inch belt Patrick you should be able to go to BSC or similar and ask for a 44 inch (or whatever) belt. I've just gone through that exercise (4 times!) to get a belt the right length for the blower drive on my MG TC. There are calculators online into which you put the pulley sizes and distance between centres, but for my application it said I needed a 50 inch belt –  a 47 inch turned out to be correct!

Thank you to those who responded about the stripped stud. Managed to remove it by using an angle grinder to flatten two sides of the stud and then used a shifting spanner (crescent wrench) to unscrew it.


I fitted a brand new water pump that has a slightly smaller pulley than fitted originally to early six-cylinder engines. That went okay, but after fitting the fan belt now find that the generator hits the steering column due to the smaller pulley. Fitting a six-cylinder into a four-cylinder engine bay has more complications than meets the eye.


There are two fan belts sitting next to me as follows:-


Dayco 15455 11A1155

Flennor AVX10X1150LA A5115


Both belts are recommended for fitting to a standard six-cylinder Austin-Healey (not BJ8) with a length of 45.05 inches, width .44 inch and an angle of 36 degrees. However these are now too long.


I have looked for a website that would allow me to punch in the length needed (say 44 or 43 inches – open to suggestions) but can’t find one. Has anyone come across such a site or can offer advice?

Had a half hour to spare this afternoon so I thought I would fit the new water pump to the BN3’s six-cylinder engine.


Of the four nuts, three tightened without a problem. but I managed to strip the thread the stud thread on the fourth.


Normally I would use the twin nut method, but with the stud stripped that’s not possible. So what to do? My 40+ year old vice-grips (mole-grips) can’t handle the strain and I don’t have a welder to weld on a nut, nor do I have an extractor.


Was thinking about filing the end of the stud flat on two sides and using a crescent wrench or what we call a shifting spanner. Any experienced advice out there?


Many thanks
