Pullers

Its true that the clutch can be pulled off by hand. I have a brand new clutch puller tool thats never been used although they are relatively cheap to buy.

The engine sprocket is another matter and if its not been off for ages, a substantial sprocket puller is needed. Original Norton pullers occasionally turn up on eBay butthey command a high price. I have never seen a similar tool for sale anywhere.

The engine sprocket pullers for alternator engines are unobtainable (NEVER lend one to a friend) but Russell Motors does have engine sprocket pullers for dynamo engines. Worth giving them a call.

With an engine sprocket, you wind the puller on and then give the end a sharp blow with a hammer. That jars the taper and the sprocket and puller fall off. Don't do what I did the first time I tried to shift an engine sprocket. Couldn't pull it off with the standard puller, so I borrowed a 3 legged hydraulic puller. I wound that up as tight as I could, then stuck some tube on the the tommy bar and wound it up some more. I was just standing up from peering at it when there was an almighty bang and the sprocket and puller shot off, straight through a galloncan of oil and embedded themselves in the brick garage wall. Had it let go 3 second earlier, it would have been skull fragments (but not much brain) as well as oil all over the garage floor. Safety first kids!

First time I took my Dommie engine pulley off it was a nightmare. Eventually I left my three legged pulled on, screwed up as hard as I dared, and left it overnight. It was on the floor in the morning. Meanwhile my 16H mag drive sprocket (the one on the engine) has proved to be impossible.

Hello I am trying to find out the correct number of teeth on the camshaft sprocket on a 16h side valve engine,would you be kind enough to let me know please? I assume that the mag end is the same? Thank you. Ian

Yes Safety first at all times you need to sit and think out your forward planing and have your tools in order first and dump bins to put your nuts and bolts in, so nothing is lost, and digital camera comes in handy so it can be use as you go , so you can remember where things came from, so Have fun guys in your Sheds or Garages or workshops, but keep out small children its to dangerous for them

too be around these old motorcycles as they manage to get there fingers in just about anything, yours anna J

Ian Assuming you mean the magneto drive sprocket on the inlet cam, they have fifteen teeth. I believe that AMC had an identical form but one tooth less ? This is not a problem unless you have one of each, in which case it only fires very occasionally !

I do have a genuine NORTON sprocket puller .Think i got it from Russels. A small but deceptively powerfull 2 leg thing made of real steel!.Fine thread and direct pull,(not angled) works a treat. Probably made by Shelleys for Norton. And No i won't lend it!.

Robert, would you take a photograph of it ? It won't take away its soul, honestly ! I sort of bodge and worry my mag sprockets, which is officially approved in the M&I Manual but it doesn't seem right !

Hi Richard, My puller is a crank one, never tried it on a mag. Don't know how to post a photo, may give it a go,As its You!.

Reminds me of many moons ago when I was trying to remove the flywheel on a mini, it would not move, so wound up the puller as hard as I could and decided to leave it overnight, just after midnight the neighbour was banging on the front door to tell me there had been an explosion in the garage, the flywheel was of, so be careful to cover any pullers left in tension with some good padding to catch the bits.
