Hi, I'm dismantling my NC21 to recon and rebuild. Have removed the back end, swing arm etc.
Engine bolts top middle and lower, the stubborn one is "The lower rear"
On the left side is a 17mm nut ( undone), on the right side its a 30mm nut (undone).
What now?
Does the bolt/sleeve go all the way through the frame?
Does it exit on the right?
Thank you for helping,
Derek

Not familar with nc21 but if its like nc30 can be problematic long steel rod running through alloy engine cases can seize 25+ years of sitting in front off rear wheel
Have a search through forum i think if plus gas heat etc doesnt work some have resorted to cutting to get engine out then dealing with it.

If you already undid the locknut off the one side its probably sized.

Wow!
I see the problem now. Helps but how do you get the lubrication into it?
I can see the need for a blow torch now.
There is a hex slot un the right side, I'm assuming that's too twist the rod to assist with removal from the right.

Thanks guys appreciate your support in this one.

The hex is a small bolt, that needs to be removed before removing the rod. You use that to tension up the rod then lock it off with the locknut.

So, i believe there's a wee rubber plug in the hex slot.
I'm not fully understanding the concept of removing the hex bolt which tensions the rod.
Do i pick out the bung and use a hex socket to remove one end?
And as before, does it come out on right side?
Cheers

Thank you for the great advice. I picked out the wee bung to allow more of the allen/hex socket to insert into the right hand rod end, with a good bit of effort it undid the threaded section and the long rod.

Phew, i was thinking this would be a nightmare.

Ok next difficulty is removing the dog bone from the swing arm.
Ive removed the clamp bolt but am not sure how the rod/bolt removes!

Grateful for guidance once again.
Cheers Derek
