Rocker removal
1.

I can see and feel the flat spot in this rocker.
2

I remover the cover using an impact driver. I use threadlock on therse when I replace them.
on this model there are threads in the rocker shaft.
3

I place a small washer over the rocker cover...
4.

then a few more and a bolt long enough to fit into the thread in the shaft
and I turn the bolt using a spanner.
5.

Then I remove the bolt, add more washers, and replace bolt
again I tighten it, this draws the shaft out further each time.
6.

The  bottom washers must have big enough holes to...
7.

allow part of the shaft to clear the casing.
adding more of these you can pull the whole shaft free for inspection.
8.

Eventualy the rocker comes free.
To refin thaft, just use a drift and light hammer and tap it back into position.
If you are about to do your own maintenance, using these pages, I take no responsibility if you get things wrong!
