    I think the position of the number changed and if you mix & match gearboxes & transfer boxes you either end up with two numbers or no number !
    There was somthing like that on Wallit, I think it has no number.

    Look at the 'sticky' at the top....Series Gearbox ID

    A quick question.
    If a mark is put at TDC on the input shaft at the bell housing,
    And a mark put at TDC on the hand brake drum.
    4 gear is 1:1 ratio ?
    The marks should both be at TDC after one complete rotation ????
    Thanks.

    4th is 1 to 1 IIRC, but you will need to take into account any ratio change through the transfercase.

    And transfer high range is 1.148:1. High range remained the same throughout Series production, but low range changed at Series 2a gearbox suffix B to C, from 2.888 to 2.350 at the same time that main gearbox ratios changed to retain the same maximum reduction in 1st-low, but with wider spaced gears in the main gearbox.

    This means you can get lower low range gears by combining the later main box with the earlier transfer case.

    Midified Gearbox

    So here it is.
    Carton of beer or so later,
    Modified to give higher gear in 4th, by Full Boar 4X4 Toowoomba. They still operate, I think, so will ring on Monday and see if they Still have mods done 10 years ago, on the computer still. ($2,000)
    I think it may be a later S3, S2 gear lever. Lever sits further forward when in reverse position, than in 1 or 3 position.
    Has syncro in 1st and 2nd, confirmed when I took the top cover off.
    Alloy welded number on top cover. 01-81 or 18-10 depending where you read it from.
    Strange JJ mark on gearbox and top cover.
    All comments welcome.

    Also noted 3 types of sealant used.
    White, original ?
    Black. bell housing and Gearbox to Transfer case
    Blue, top cover, square inspection cover, 1/2 inch bolt heads and rear plate, where overdrive/PTO would be fitted.
    Doesn't look like Transfer and other box have been separated. Will look for sealant when I turn the box over and look underneath.
    Will an engine stand take the weight of the box, if I bolt the bell housing to it ????
    Just remembered I have an Inspection camera, the kids bought me so I could look inside Gilberts Chassis rails.
    Thanks.
