bloody hell!

I left the rotor on the crank until the motor was completely stripped. It’s quite easy to tap the alternator rotor off using a well placed piece of wood and hammer. Undo the alternator rotor bolt now though.

The primary drive can be removed using the 16mm long engine mounting bolt, using it as an improvised slide hammer.

Bring it up Roo, just let me know so i find mine from its safe place!

M16 x 1.5. Used a car wheel bolt that I bought for a few quid. Shape the end. Used it four/five times.

Thanks chaps,
Still waiting for the puller so carried on after you all saying that it’s easy removable whilst off so carried on as I had a free afternoon.

Well that was a bugger!
Everything that could get stuck, was and everything that was stuck was encased in thick shite, tar, and black goo. Presumably from the weeping motor, left for years.??

The whole lots apart and I now have the hideous job of degreasing the lot prior to getting it off to get vapour blasted in Yeovil.

There was some interesting goo in the pan, the consistency of extra thick peanut butter, a bugger to shift but it’s coming out with a great deal of hot water and elbow.
The motor is blathered and once split……there was a whiff of sealant between the cases and only in certain places. Where there wasn’t any the motor has pissed oil out and presumably moisture also, the oil thst came out was definitely on the browner side of awful!.

The primary chain is proper goosed, as is the cam chain, but strangely I forgot to have a look to see the extent of the chaffing of the cases to see how destructive it’s been whilst I was out in the shed.

It’s been standing for years as half of some of the internals have a mist of rust on where some bits have been out of the oil whilst laid up, like the selector drum

All should nanny up but I’ve not been here with one of these motors before to this level so brace yerselves
 for all the daft questions as they’re coming, just don’t know when yet

Just from observations whilst stripping it I’ve a few questions but I’ll make a list and bob em on here nearer the time of need. For now it’s degrease tastic for the foreseeable ‍

Yup, that primary is totally knackered.

How’s the rest looking Roo?

[Laverdaroo]

The whole thing is a lot of a shitter but I WILL bring it back, it deserves it

[Sesman]

👍👏

How’s the rest looking Roo?

To be honest, better than expected. I didnt neck any bolts off so thats good!
Like I said a few bits witha bit of rust on but nothing that a good nanny wont sort out. I havent had alook at the bearings at all yet, nor the shells etc. I was just on for a strip down, bag up an tidy up.

Ill order some more bags later and then as I take something out of a bag to work on it gets put away fettled in a clean bag ready to re fit. Thats the plan any way but for now i need to get the cases gone as they take up a lot of bench space .

I have a few questions but until its in my hands its only half a question so I'll wait but for now the bikes stripped and bagged the barrels are off for a rebore and only show minimal marks from standing but Itll be done as a matter of course.

The first set of pics you sent me Roo show a snapped off bolt just above number 2 spark plug.
