Thread: Chev V8 Diesel to Isuzu MSA

Looks good Sheldon. The fixing bolt at 6 o clock is 155 mm from centre so should be OK

4L80 out now. Big heavy lump of a thing. Its certainly a strong box.
Just as well this truck sits high, heaps of room to slide it out.

Getting the "new" transfer box ready for Sheldons adaptor housing by transferring the mounting hole positions from the 4L80 adaptor.

Finally decided where the gearstick is to go. Not much option really. The two cables curve down in front of the engine and will lead back to the box when I get it in.

Picked up The Grubbs housing this week. Looks good. Sat the LT 95 T Box on it to see what it looks like. Had to put it all in for a dummy run to get the T Box level with the chassis mounts before I drill the bolt holes joining the T Box to the adapter housing.
Cant do much more untill the engineer in Gympie gets the splined shaft done. Said call back tuesday.

Picked up the shaft yesterday. Gave it a spin in the lathe and it runs true.
Looks strong as well and I guess the weak point will be the mainshaft gear splines. The engineer said coarse splines like that are for slow speed like a tractor PTO. High speed splines should be fine like the ones he has fitted.
If the mainshaft gear flogs out again I will have him make a new fine spline shaft and cut out the gear centre and fit a fine spline to suit. Has to be a better way of secureing than that circlip surely.

Got the MSA bolted up to the Dellows adaptor. Next step is gear linkage , clutch, and driveshafts.

The Grubbs LT 95 adaptor is on with studs and bolt holes drilled. Have to drill new holes for the T box to chassis mounts as 90 mm shorter than the 4L80 and 20 mm shorter than the T 700 positions.

No room for a clutch pedalbox but since removing the two transmission oil coolers I have room in front so drilled a hole in floor and put in pedal like a series one.

Made a little rocker arrangement with a nylon bush in it so have a straight shaft. This goes to a reworked Isuzu clutch arm and pivot. Picking up the sleeved master tomorrow.
