Engine removal question
 

Could any of you SV boffins out there tell me:

When removing the engine from a K4 650 there are slotted knurled type nuts on 2 of the left side engine mounting bolts which presumably locate the motor correctly. Do I need to turn these to remove the motor and if so, do I need a special tool to do this?

There is a similar thing on the right side on the swingarm mounting bolt. Do I need to turn this to remove the swingarm?

Thx in advance.

yes you do, the outside ring needs to be backed off in order to undo the the inner bit, you need either a castled socket (special tool) or make one, or carefully use a drift and hammer (if you know what you're doing.

If you don't release these, you may get the bolt out, however getting the engine in again will be a nightmare.

Cheers Mark.

As Mark said...

But you can make a castle nut adaptor out of an old socket with a dremmel if you so wish. It might make things a bit easier putting it all back togeather....

Halfords have a peg spanner for, I think, £3.99 which very nearly fits- it'll need the pegs thinned down with a grinder or dremel is all. Hidden away in the cycle tools and spares section... It doesn't have a 1/2 drive, so you either need to work it with a wrench or with a truly monstrous socket. Easier than grinding down a socket I suspect, for the lazy.

Could you use the peg spanner to remove the swinger on a curvy?

Pretty sure you could, yep. I've not actually done it yet though.

Would it be the right size to use on steering stem castle nuts as well?

Don't think so... It's quite bulky on the inside, I think the stem would be an issue.
