Thread: Gearbox swap - issues

G'day Scott, Bit of a bugger having to pull it all out again . Which throwout bearing did you use. The Isuzu one has a metal sleeve extension between the bearing and the plastic sleeve whereas the RR one does not. Also did you use the correct pushrod as there are 3 types, one for RR LT95, one for Isuzu LT85 and another for the Isuzu LT95. The Isuzu LT95 one is the longest.

I used the bearing that came out of the LT85, which didn't have the metal sleeve as I read in another thread they were the same bearing for both.
http://www.aulro.com/afvb/isuzu-land...fferences.html I have the sleeved one sitting there as well.

You live , you learn.

I used the long pushrod which is for the LT95/Isuzu combo. My father suggested making up a new longer pushrod out of a V8 pushrod. I'm not sure if this will over extend the throw of the bearing and push it off the shaft.

Actually, I have also noticed that the front drive shaft I have seems to be slightly shorter than the LT85 one. It still fots, but the slide joint is extended out around 30mm. I might have to source the correct one before I take any trips off road.

Maybe the bearing came from a V8.

My question is why change trans? The 5 speed overdrive absolutely makes the 110 Isuzu as a touring vehicle.

It may have, but I'm wondering how it worked with the LT85. Maybe it had a longer pushrod to make it work. Is it possible to just use a longer pushrod, or will it push the bearing off the end of the sleeve it slides along?

I've alreado got the drive shafts back off, so it's just the bell housing bolts and gb mount bolts to go. The engine crane makes light work of the actual lifting and moving.

As for changing the box, the overall gearing will be the same, give or take 50 rpm at 100 clicks. Swapping to the Lt95 will be more durable and is cheaper than rebuilding the LT85.

Wrong. Do a gear split chart and see for yourself. 100 in 5th =2000 rpm. 100 in 4th = 2400 rpm.
