CL450 - Crank split? to replace the bearing retainers

<< < (2/2)

Bryanj:
Yes you will have to split it, its the only way to get the head off, and re rivet a new link in

I have never worked on one of these engines before.  I have rebuilt a cb360 and cd175 engine ages ago.  I thought these 450 engines were bulletproof, or a good as.
I have changed the oil regularly, but something has failed or will soon.

And I have noticed that the cylinder head is a large one piece lump.  And it's obvious now that the head won't come off with the camchain still in place.

And the engine has to be out of the frame to get the head off............. And I thought it was a Sunday afternoon jobbie with a couple of spanners.

I tested one of the lumps of metal that dropped out of the oil drain hole and its magnetic.  Maybe I should have waited before buying 4 new bearing retainers from DSS.
