Thread: Chev V8 Diesel to Isuzu MSA

Personally, before proceeding I would manually jack the clutch fork to the point of full release, you could use a scrap of angle iron on the slave mount and a piece of threaded rod. That way you know exactly how much travel you will need, or if there is another fault, eg clutch plate binding on the spline.

Thats a good idea bee-utey. Been in the back of my mind but because its all new stuff I havnt bothered. Took the slave to town to get sleeved to 3/4" today so might fiddle with it tomorrow.

Made up a plate and buka rod with nut.
Started truck in gear with one back wheel jacked up.
Got under and screwed up nut till wheel stopped. 24mm of travel.
Got in cab and could not engage 5th & Rev without graunching.
Screwed up some more untill could engage all gears without noise. 29mm of travel.
Should be picking up sleeved slave this PM. Then have to turn up a matching brass piston on the lathe, fit the seals and keep fingers crossed.

Picked up the slave. They had to put two sleeves in it to get it down to 3/4". You dont want to know what he charged.
Turned up a piston in steel as the clutch bloke said brass was too soft. I dont think it is but never mind. Put everything together, bled it and cranked it up. Can now engage all gears with one wheel up. No crunches. Pedal is a bit heavy but cant complain.
Plug all the pipes etc back on tomorrow and go for a road test.

So size matters...

Yup, and just sometimes bigger ISN'T better.

Good to hear its working.

Went for the first test drive today around the bottom paddock.
Buying from a wrecker is always a fingers crossed event but all the gears work without too much noise except I dont have synchro on 1st & 2nd. Bit of a worry as the book says synchro on all gears. Anyway should get me to Sydney and back I hope.
The other thing is the gearchange is upside down and back to front. Seems the cable shift should come out the front not the back. No time to change it before Expo so will have to get used to it.
Anyone rebuilt a MSA? Any hints on fixing synchros.
If all goes well I will fit the third axle drive and bottom PTO when we get back.

Try an oil change first. someone may have filled it with EP gear oil.
