I'm trying to work out my idler gear end float and need to know the thickness of the transfer case gasket when compressed.

I've been told that the typical size is 0.032 and will compress to 0.030, however the gasket I was supplied by minispares is 0.036 thick.

Am I right in thinking that It's compressed size will be 0.034. Sorry if it seems a stupid question but I want to het this right!

You need to use the genuine gasket sets as the no gen ones have gaskets that are too thick.

Best thing to do is dry-assemble the transfer case and box with the idller, but no engine and measure the end float.

As above, but I have one here which I use for dry building and it measures between 0.133 and 0.134 (compressed), this is the one which comes in the AJM804B gearbox gasket set.

Do you mean 0.033 - 0.034?

in my experience when I used to do loads of boxes, the gasket sets often contained different thicknesses of the transfer case gasket - all seemed to be down to what day of the week the gasket set was put together...

Ording a transfer case gasket on its own would result in a different thickness one all together too...

Different suppliers... different thicknesses..

so, as above, only way to be sue is to dry build it and measure as necessary....

Yes, sorry....

I had one which looked to be the correct one but which came up 0.005" too thin. Good job I did a trial build first as I hadn't touched the gearbox or transfer case and it should have been a straight re-assembly.
In fact, you can roughly check the transfer gear float with the engine on the box if you remove the 'red' seal and the primary gear to gain access.

I keep back all the gaskets from previous builds.The variation in thickness between them can be used to your advantage to get the idler float right.Damn site cheaper than purchasing 2 idler thrust washers.
