My Alternator has decided to give up on me!

 

I just wanted to check if anyone knows if this is the correct replacement for my car?

Mmm could be that one or this http://www.minispare...rs/GNU2521.aspx
The belt will give the clue if no part number on your original one.

Had a chance to look at it over the weekend and it seams that the belt has just stretched so its slipping.

 

Have you ever had to replace the same belt on your 35th anniversary cooper? which belt would it be?

 

Thanks!

Hi,

That's an MPI belt for multi groove pulleys, I didn't think they fitted them on SPI cars?

Cheers  :proud:

If it's a JDM car it'll likely be distributorless and have the multi groove pulley - my 1998 Cooper certainly is. They're a mongrel of an MPi engine with SPi throttle body / radiator etc. and can be a bit of a nightmare choosing the correct bits!

Hi,

I knew it was dizzy less and SPI but didn't realise it had the MPI belt setup too.

Cheers  :proud:

For information, the poly-v belt needed for the air-con / alternator is a 5PK1010ES (Minispares are as cheap as anywhere if not cheaper), useful to know if you get caught out.

What are these later cars (mine happens to be a UK 94 Spi so no AC) alt supposed to be putting out? With my wipers, blower motor, and lights on, it seems mine can't really keep up. With the lights and interior fan on, when the wipers go (I installed intermittent wipers) I can hear the fan motor dip.

Sorry been away for business...

My Anni is different as it’s a 1996 so an SPi block with the MPi alternator bracket on the head and combination of very short drive belt from air con and longer belt on rest.

Give me a shout and I can take a look if you want.

Depends on year, earlier ones (pre U.K. MPi) are SPi block and dizzy but with different bracketry to mount alternator in similar high position but with standard single v belts combo 1 long, 1 very short.

As per FlyingScots comment, if you have that type of JDM SPi (as I do) you need these belts. Rare to get in the UK so I get them from David Ainley, who ships them over from Japan. Your engine clutter will look something like the other picture if these are the belts you need, the alternator is mounted very high in the engine bay.

Seems we might need a forum section just for JDM Minis!
