BMD serpentine pulley - issues with bottom pulley

[Marriedblonde]

I've bought a serpentine pulley for my new lump.

The bottom pulley - am I missing something, the crank is keyed. I slot the pulley on. How doesn't it hit the engine case? I can't seen anything in there to stop it catching on the case...

Thanks,

J.

Are you saying it does catch on the case?

From memory, the crank nose is machined to a certain depth, then there is a shoulder that stops the pulley found on further.

I have the Iron Cross pulley, nice bit if kit.

I am not certain, it just looks like it will!!!

PM zed on latebay he had to throw his serpentine pulley out for exactly the same reason. From memory he had to go back to stock pulley, might be a bad batch I guess?

Thanks Md. Will do.

Zed's problem was to do with case clearance, not the pulley.

if you have a stock pulley to hand measure the depth of the shoulder and compare them.

Not wishing to sound funny but everyone that's had these serpentine pulley kits has had problems. They look great but if it were me I'd either stick an OEM pulley on or an equaliser.

Put a shim behind the pulley. There are some kits for sale made to align crank pulley to alternator pulley. Just buy it and use all the shims needed.

When I asked my engine builder what he thinks of them his response was: their on equal par with Porsche fans.... ****, they over complicate a proven design :| We're going with a Berg equaliser and a spin-tru on my 2110. Even before Hector said that I'd heard bad things about them.

The jury is out on the serpentine kits. I think you will find one engine builder who is VERY highly regarded recommends them...

Anyway back to my question. It appears a lack of knowledge on my part is the reason I thought I had an issue. What I didn't know, and couldn't see, is there is a washer thingy at the end of the crank, it looked to be the same as my case, hence I thought it was... But its not, so no problem after all. Just need to get it fitted, was due to be done today but with one thing and another it will be monday.

I've had one on my 1776 for the last couple of years as I destroyed my stock top pulley whilst giving it some welli leaving vanfest
Haven't had any problem
It's a BMD iron cross
