4 speed 1.9 waterboxer to 5 speed td (AAZ/TDI)

Post by seanadams »

Hi All,

got my first camper, now thinking of getting rid of the fuel guzzeling waterboxer with something more reliable/fuel efficient.

i'm after the following answers please if some one can advise:

1. will a five speed diesel gearbox go straight in?

2. will a AAZ or TDI engine fit straight onto a 5 speed diesel box.

3. does anyone have a list of what you need if fitting a AAZ or TDI (I taking it, that the AAZ is the old 1.9td lumb thats been knocking around for years)?

that will do for the moment.

Cheers, Sean

yes, ideally you use the diesel specific 5 speed mount which you get with the box, if you are at present 4 speed you'll need the gear linkages too, esp get the rear part from a diesel as the cup is a different length, but the stick and the front linkage is speed specific
yes, you may have to swap the seal "pooh" plate depending on the engine I think, but I don't do diesel, see below
there's a section on brickyard with aaz conversion stuff

ps fuel economy will probably not reap you the cost of conversion anytime before the shell rusts away unless you do hefty mileages and why would you want a tractor engine in it anyway, horrible noisy ,dirty rough things :twisted:
to do a tdi properly you'll need to mod the box ideally, not cheap.....

lpg it and stay as you are imho, but unless you do more than 5k miles a year just drive it as it is as the cost benefit and space lost doesn't justify it
:idea


runs away :rofl
