What is 'end float?'

[BegesRus]

I'm used to doing the valve/ tappet adjustments OK but what's all this I hear about first checking end-float?
I've checked my Clymer and yes it refers to end-float but - where do you check it? where is it?
HEEEEEEELLLLLLLLPPPPPPPPPP

End-float is the amount of side-to-side movement of something along a shaft. It could be a gear or a bearing or perhaps a rocker etc.

I'm not familiar with airhead engines but I would imagine that it refers to the movement of the rocker along the rocker shaft. Measure by sliding a feeler gauge between the rocker and something else along the shaft length. Change or add/remove shims as required.

PS If, in error, you've picked up an 'artistic' magazine instead of your Clymer manual, end-float means something else altogether

Just as Greg says it's the end float in the rocker arm. This is my Mono g/s being checked after the heads were rebuilt.

You can slacken the bolts holding the rocker arms in place and simply pull the studs together to take up the slack but it's better to shim them.

Cheers guys - I can see what's it's about now.
