Thread: Hmm total carnage

Well the autopsy has been done on the gear box. Now it seem I have yet again inherited some one else's less than perfect workmanship The bozo that did the marriage of the 4bb1 to the range gear box had some distance issues. So he had made a extension that fitted on to the tube that would normally guide the throw out bearing. Idea was ok. Just did not make it strong enough for the clutch I`m now using. When I got the box on the ground I soon discovered the shattered remains of the tube and the plastic piece that the clutch fork would have pushed against scattered around the inside of the bell housing Soon as the new clutch statrted the normal Isuzu death rattle ( old one for some reason did not, was a smaller clutch ) it all went horribly, horribly wrong. Another area of damage is the main shaft. Part of the spline has been worn by the thrust bearing bouncing around after it separated from the tube. Sooo have to now make some new and hopefully stronger bits.

Just have found that some thing were done better than others. The clutch has been one problem. To make the fitting of the gear box to the motor easier a early series three clutch was used. This clutch was not adequate for the torque produced by the motor. The clutch plate spline tore free of the clutch plate. I then fitted a Isuzu cltuch that will handle the torque. But now the throw out mechanism has packed it in.
Justin you are mostly correct. The conversion is based on the earlier conversion. And thanks for that bit of info. But although my motor is a Isuzu it is a 4bb1 , not a 4bd1 as used in the Defenders. It was sourced from a small truck and has a part bell housing that covers the clutch. Which then moves the gear box back a long way. Not sure if the 4bd1 had a part bell housing as well. Would like to see one of these later bell housings. Would the bolt pattern be the same?
One problem now. If I alter the over all length of the motor and gear box it will mean altering the mounts and tail shafts. Not some thing I`m keen to do.

Sounds like its up to you now to do the job right
