While I'm waiting for parts to arrive I'm getting on with things that just need time.
Tonight I stripped down the rockers to get the rocker cam follower pads polished up so that the new cams don't get wrecked.
Those pads are hard! Looking at them under a magnifying glass they look like they have a layer of what is probably Stellite fused onto them. Whatever it is, it took a fair bit of work to remove all the marks made by the old cams.
When I came to assemble them back into the cam carrier, I was concerned by the amount of wear on the rocker spindles. Needless to say, I had checked every thing else on the heads except them!
Then, BRAINWAVE!
Take a look at the pic. What do you see?
Look carefully at the lower rocker spindle.
Both rocker spindles are identical and, due to the way the rockers sit on their respective spindles, the spindles can be swapped from one side to the other so that the rockers now sit on fresh metal.
If you are doing the valves or valve seals you will already have the cam carrier off, so take five minutes and do this. The spindles will just push out (or a light tap with a soft drift) leaving the valves and springs just sitting there if you're careful.
Swap the spindles over and turn them end for end. Make sure that the oil holes point down towards the cams.
I also noticed that the springs can obscure the oil holes so make sure that they are turned so that the holes are clear. I don't know whether or not the springs turn of their own accord when the engine is running; there is nothing to stop them which seems poor design to me.
JOB DONE!
