Another fella in the UK has done the same to his 110, and here's his conversion shaft.. Still worries me how this shaft will handle 200+ hp and 500nm of torque...

The Jack shaft that goes with the 1:1003 Transfer box is hollow, as a bolt is fitted into the end of the output shaft on the Torqueflite 727, I have included the bolt with the Jack shaft and adapter housing. The Jack shaft looks to be a similar length to the pictured one.

I also solved my hang up with the hand brake actuator mechanism, so happy now to pass that on as well, along with the gear change parts.

As for the torque the shafts can stand, compare it's size with the shaft on a 200 HP, 1000 RPM, tractor PTO, however those tractor shafts do sometimes snap under load as you probably already know.

Now who is doing a car trip to Tassie that can act as a courier to bring a transfer box back with them?
But I think AULRO protocol dictates that this request be formally put in the courier section.
.

Been following this shaft discussion with interest and to say if it is welded it will break is crap .A LT230 transfer case is completely different to a series in that the gear is fully supported and the shaft can be designed as fully floating If properly done it can still break but it won`t be because of the weld
Just my 2 cents worth

The man makes a good point, not something that had registered with me either.

I don't think the ones that have been done are babied by any means, so if they were going to present a problem then it's likely have happened by now?

Either that or 'Rakeway Engineering' offer an LT230 input shaft with a drive flange machined into it to allow conversion to remote operation.
Might make length an issue though?

Actually, they do a lot of shiney bits for the LT230. Clicky

The shortened output shaft is something that tempts me for my 101s lt230

They've got some nice stuff.... I'm wondering if that input shaft (pictured) uses the input shaft that's hopefully coming with the 'Tazzie Transfer Case'...

Once I work out what's behind that back cover, that might be coming off too.... If not, Ill be modifying that prop flange into a shaft pictured earlier like Nick and Tim did in their Cummins powered Defenders... That 4 bolt face lends itself to becoming a plate mount or something!! That nice big hydraulic pump will drive a big rear under floor mounted hydraulic winch nicely!!!

Nice work AM! Did you make it yourself?
