removing rocker arm pins

Actually, it took me no time at all- maybe 30 seconds apiece. As I had no idea what I was in for I assumed it was going to be tricky, but they all came right out with minimal force. Should it be harder? Sometimes when things are too easy I start to imagine the worst.

As far as compressing my valve springs to remove the retainers... that's HARDER than I imagined, so I guess it all balances out!

They aren't tight at all.
The trick is when ya install them later and have to get them in the correct locations. ...........lm

Well, I 'bagged and tagged' each one. I hope that's enough. I TRY to pay as much attention to a part's location and special features etc when I'm dismantling, but sometimes I get too caught up in the act and my attention to detail suffers. There's a learning curve here, that's for sure, but I'm getting better all the time. At least...I hope I am.

The secret is to put the right side parts on the left.
That way ya have a smooth surface on the pins at all 4 corners. ......lm

Ah-HA!
It's been said here before, but it bears repeating: there's no substitute for experience. Thanks as always, LM.

The key is that intake pins and exhaust pins have 0.5mm difference in diameter IIRC.

Where the rocker arms ride is the same, but where they go into the head is different. On engines that have been torn down a few times the holes often end up slightly oversized from fitting the wrong pins.
