The bad part is you are going to be buying a lot of new parts. The good part is they are readily available.

Hi Lads,

I have no plans, at the moment, to rebuild this engine. My main purpose for stripping was to learn, through a hands on approach, about the MK3 Norton Commando engine.

The secondary purpose was to yeild some spares for my current on the road MK3. The cylinder head & barrels seem fine, I've yet to check the clutch bit + ES parts but so far they all look OK.

I have a feeling the gearbox is going to be mainly full of rust which as others have said does not bode well for the repurposing of the gears!! There's a chap I know who has a beautiful Norton cafe racer who could use the gearbox so I'll donate it to him.

I'm presuming the crank + crankcases will be OK, so all in all I hope to end up with all the major lumps of metal that make up a Norton as spares I can recondition these parts as I see fit and when funds allow :roll:

The engine didn't cost me much and the education I'm getting was/is well worth the price of admission :mrgreen:

Hi Lads,

Small update.

I donated the gearbox to a fellow Norton owner who said he had a use for it.

I'm going to wait until I get a few specific tools before I split the cases. I don't want to cause damage to the cases or any other parts with the tools I have at the moment + it gives me an excuse to get more tools :mrgreen:

Hi J,

This is the list so far:

I know some of these tools are not absolutely necessary but I'm in no hurry & don't want to cause damage to a part.

I'm also considering an investment in a electric hammer wrench, Clarke seem to do an OK one.

That's a head of steam on the tool list. The postie,s going to be humphy backin carrying that lot.

The pinion extractor and a bit of round bar would probably get it to bits, they're not that expensive but if you want a loan you can have mine. A good hide mallet should split the cases,it's always worked for me.

J,

Thanks for the offer, that's very kind of you.

I suppose it's the classic debate we guys tend to have, need or want, do I really need these tools! or . . . . . . :mrgreen:

As I said from the outset I'm looking upon this engine strip as a course in the University of Norton, I'll learn lots, probably from my mistakes

Due to work commitments things will be slowing down but I'll pop up a post now & then as I know you guys are on the edge of your seats waiting for the next instalment

Hi Click

I have several pullers for commando including the 3 jaw pinion puller. I live near Mullingar and you are welcome to a loan of them. I would like to discuss with you a smoking right hand pot which is using a lot of oil of late.

Hi,

Thanks for the offer of the pullers, most kind.

I'll send you a PM with my contact details so we can chat about that smoking RH pot.

I made my own equivalent of this tool. I ground the heads of 3 bolts to fit in behind the timing gear. I made up 3 "z" plates which joined the bolts to a 3 jaw puller. I used a strong hose clamp to compress the modified bolts hard in on the gear and pulled the timing gear off.
