Alternator Removal
 

According to the great book of lies I need to remove the alternator in order to facilitate the splitting of the crank cases. Now the first question is, do I have to?

The reason I ask is I don't have a rotor puller tool. So is there a work around for this?

The second question assumes the answer to the first is "yep, you gotta". Now I have found this thread, which gives the specifications for a removal tool (a bolt M20 x 1.5 mm pitch). And I've found them listed in a pack of 25 at Screwfix, I assume the pitch is a typo in the other thread and should read M20 x 150 mm, please correct me if I'm wrong.

But as I don't need 25 of them is there a bolt on the SV that can be used in its place or does anyone know of somewhere that will be open on a Sunday and sale these bolts separately?

Not done it myself so don't know but no it's not a typo, it's not the length (as 150mm would be) but the pitch. The pitch essentially being the distance 1 turn would screw in the bolt but is defined as the distance between two adjacent thread peaks.

Any decent fastener place should be able to get you just one, something like this http://coburnmyers.thomasnet.com/ite...-12-9?&seo=110 is what you want.

Thanks for the clarification there Druid.

Thought it was wrong as all the bolts in B&Q were listing the M size followed by 150mm, 80mm, 60mm etc. Coincidently B&Q only go up to M12 bolts.

Re: Alternator Removal
 

When listed like that it assumes the 'coarse' pitch which for M20 would be 2.5 or M20-2.5, a M20-2.0 or M20-1.5 would be "fine"

In the end I got one for a few quid from Wessex Fasteners after the first fasteners place I tried didn't have any.

The shop is run by a couple of old boys who were like a double act. But as soon as I asked for the bolt they replied, "Making a puller?", at last somewhere that new more than what was written in the catalogue. Just a shame they weren't open on a Sunday…

Heh, some of the "put in with the foundations" type old boys in engineering are a great source of info about all sorts of stuff, so long as you can nod with interest about tales of methanol burning velocettes and stuff :-P

I had to take off the alternator to replace the starter clutch.

I ended up buying the proper bolt for the puller, but used a big adjustable spanner in place of a rotor holder. Just required a LOT of weight on there to loosen it, like 11 stone of body weight...

Brothers are good for something! lol

Re: Alternator Removal
 

Out of interest the proper Suzuki puller, is it just a bolt then?

And I completely agree about it needing a lot of weight. I was using a 32mm spanner locking against the table to stop the rotor from turning and then a 2ft breaker bar on the bolt. I then had to put my weight on the bar while making sure the spanner didn't slip and holding the rest of the engine in a sort of headlock arrangement to stop it from tipping over.

Not looking forward to tightening the thing back up.

just get breaker bar under load then wack it sharp and hard, the rotor will come off easier
if you have a impact drill, it will make it soooo much easier
