When is a motor not worth working on?

Interested in as to why?
Also, because I kinda don't wanna buy new bearings if I can avoid it, but also don't have a slide hammer, are there any alternatives in cleaning the engine, where I can leave the bearings be?

Cos its a bugger to pick up all the bits!
Oddjob:
You don't need a slide hammer, to remove the primary shaft leave a footrest on the footrest hanger bolt and use that to screw into the end of the primary shaft, using the footrest you can get the primary shaft out easily.
If your not prepared for the gears falling off it's easy for it to catch you unawares, one of the needle roller bearings has the bearing loose inside, the other uses a cage to hold them, if the loose bearing falls off it's a bitch to find them all. Also easy to misplace some of the thrust washers that fall off at the same time.

Thank you, that foot peg tip is quite a useful hack :) I've noticed people taking these engines apart, usually use a slide hammer to get these bearings off (outlined in red on attached picture). Is there an alternative way of getting them out, or am I getting a slide hammer? I can't really picture how the foot peg trick will get the whole thing out actually. Do I just pull really hard and hope it isn't stuck? Also, will I damage these bearing getting them out either way, or is there a way to get them out without ruining them? Is there any other bearings that will pose me any problems?

And last one - I see a lot of cir clips in the bottom end. Can I reuse them, or is it best to replace them with new ones when taking the engine back together again?

I stripped my motor with no special tools,other than using the footrest mount bolt dodge. Leave the alternator rotor on until the moor is split than use judicious blows with a piece of wood and heavy hammer or similar to remove it. ;
Of course, there is no substitute for the correct tools….or is there. ;D
