Thread: Isuzu MSA Gearbox to LT230

I thought the adapter housing was dry. Isn't there a seal on the transfer case end of that adapter shaft, and a seal on the gearbox output flange?

I've thought a bit about the spline lubrication previously and considered just running it wet and allowing free flow to/from the transfer case (added advantage of increased transfer oil capacity), or just keeping it dry and fitting a grease nipple in the drive flange and an access plug in the adapter to get a grease gun onto it.
Like a axle drive flanges, I don't think it would take much lube to make a huge difference to the spline life.

Yeah steve, housing is dry, adapter shaft bolts to output flange on gearbox.
My thought was to bolt a flange on there made to suit the seals with an internal spline and then run a small axle/shaft from it to the intermediate gear, oil should run along the shaft oiling both splines, this shaft runs solely in the transcase.

Not sure on how you could apply the sals flange?

Just a matter of a register and re drilling to suit or you can go as mine

Using it as a drive flange bolted to the gearbox output flange.
Stub shaft from there into the transfer like AM has done.

Noel - I like your lubrication idea.

Wonder if HTE would be interested in doing some drive flanges with only 4 holes, and some stub shafts to match

Steve

Cheers AM, thats exactly what i was thinking. I will be contacting hte or the likes as soon as i get home.

Steve if you are interested i will get a few made, i will be sending 1 mockey's way for his help.
Cheers

If the Outcast unit should go south then I might be interested in one for spare, or even more for future projects.

AM, whats the shaft out of?
