    LT230 intermediate preload problem

    I'm on (almost) the last step of rebuilding my LT230 - setting the bearing preload on the intermediate gears with the collapsable spacer. I have the collapsable spacer inside the gears, intermediate shaft in place with taper bearings, but stake nut doesn't take any end float away.

    I'm up to 100Nm and there is still tons of end float in the intermediate gears.

    I found this on youtube and it shows close to how much movement I still have in the intermediate gears.

    What have I done wrong?

    You haven't got it tight enough yet to begin collapsing the spacer. It IS a collapsible spacer isnt it that you have been given???

    I sure hope so! It came in a rebuild kit from Ashcroft's, so I reckon so.

    Thanks JC, I will break out the breaker bar then. If it is no surprise it hasn't started taking up at 100Nm, then no worries. I wasn't expecting that much - didn't want to snap something on the last step!

    If you go to the Gold Coast section and read through Presto's rebuild of his 110 you'll find a post about doing exactly that.

    It takes quite a bit of pressure at first but once it starts to collapse you feel it lighten up and then start the preload.

    I'm done. Once I got out the breaker bar it was much easier.

    Questions Damien?

    Are you replacing the input gear?
    If you are I am just seeing if you need to re shim it?
    And the rear cover that the bearing race is in, does a gasket go under it? (Between it and the tcase)

    I have just fitted my modded input gear I got from ancient mariner, and either I need a gasket for that plate or to reduce my shim by .95mm.
    It has been a while since I stripped this box and can't remember if it has a gasket or not.

    Early ones had gaskets, later ones are sealant. Before serial 288709E is gaskets and after is sealant.

    Either way, yes if you change the input gear you'll need to re-shim it. The shims are behind the tapered bearing track in the plate. I doubt the gasket would ever be that thick anyway. I would re-shim it and just use (a very small bead of) sealant.

    You must have changed the input bearings / bearing tracks if you're using a new input gear?
