Which type should I get ? Saw some cheap ones in Bunnings which is digital and have a resolution of 0.1mm. Is this 'precise' enough?

If not, what brand should I get (and from where) ?

Mic's sould at least measure 0.01mm. A 0-25mm Mic will be all you'll need for shim's. Really the only way to go as far as brands is Mititoyo. Try and stay away from digital ones, I have found them to be not as accurate as the normal veriety and see, to be a bit gimicky to me.

I am with Stace

all my measuring gear (caliper dial gauges etc ) are Mititoyo
...which are not cheap btw
and
measuring shims????
all the shims I have ever seen have their thickness screen printed
on 'em ...so no need for micrometers

Thats what I thought..

Hey that's genius !!! So you think they don't change in thickness (due to wear) ?

Come back of the year to Andi LMAO :wink:

Isnt it generally the distance between the shim and the valve clearence, rather than the shim that changes? hence you measure the distance between the two at a certain point - and find the correct shim for it ?

Yes, However shims will wear over time

Shimmy shimmy!!!

Damn!! I need a micrometer then :cry:

by **Smitty** » Mon Aug 21, 2006 3:12 pm

no...
if you think the shim is worn....
buy new ones

by **Duane** » Mon Aug 21, 2006 3:15 pm

But you still have to measure the distance of the valve clearence no? to decide what shim to buy, hence you still need the tool.

by **javaman** » Mon Aug 21, 2006 3:31 pm

From reading, the process of shims replacement is not as simple as buying a new size shim. As the thickness of the shim will be based on overall condition (determined using a feeler gauge while still installed). Obtaining this number we can get the desired gap if the true thickness of current shim is known

Stop trying to make it more technical than it needs to be.
Shim size printed on 'em is all I've ever gone by as I ain't trying to blueprint the engine
