tonedef 9 Posted April 15, 2022 Does anyone know of a reliable source of alternators with the original 7 groove pulley? Everything I look at seems to be 6 groove and when I quote the part number 037 903 023 suppliers just tell me the 6 groove is a direct replacement even when I show them a photo and say count the grooves!

Cressa 44 Posted April 15, 2022 I got mine from TPS in Nottingham. Was a couple of years ago now but worth a try Quote Share this post Link to post Share on other sites
Dox 23 Posted April 15, 2022 (edited) Swap over pulleys? Golf v5 / v6 is usual upgrade with a pulley swap? Edited April 15, 2022 by Dox Quote Share this post Link to post Share on other sites
fendervg 32 Posted April 15, 2022 Yeah, swapping over the pulley is now the standard approach. Everything else is a straight fit. Quote Share this post Link to post Share on other sites
tonedef 9 Posted April 15, 2022 Thanks for the replies, as I thought. I had looked at swapping the pulleys but didn’t have a long enough 10mm 12 point driver (for the new one) or T45 (for the old one) to go through the centre of a socket and stop the shaft turning. Looks like I’m tool shopping tomorrow! Quote Share this post Link to post Share on other sites
fendervg 32 Posted April 15, 2022 Can you use a water pump pliers or spanner on it to hold it steady?You can also get them undone one by one by holding the other one steady in the other direction - but the last one will be a pain then! Quote Share this post Link to post Share on other sites
Dox 23 Posted April 15, 2022 Old belt around the pulley and clamp in a vice? You'll need an assistant and rattle gun if possible Quote Share this post Link to post Share on other sites
tonedef 9 Posted April 15, 2022 I’m sure I’ll manage to heath something up to do it, now I know there’s no better alternative I’ll go for it! Quote Share this post Link to post Share on other sites

Ask Vince who he sends his off to be refurbished- my replacement was a Bosch and upgraded to 120 amp form memory it was a 90 before so bonus ha.

Don't clamp the pulley, wrap the pulley with the belt and clamp the belt into the vice, pulley above the vice Quote Share this post Link to post Share on other sites
tonedef 9 Posted April 16, 2022 Step 1, 7 groove pulley removed without too much grief, same can’t yet be said for the one in the new alternator! Quote Share this post Link to post Share on other sites
