Cheers for that Phil. Hey GT i cant find F60L recent pics thread. Also a big shout out to Hugh Davies we were going to work on the truck tonight. However i gave him a call to see if he was still coming over and the answer was no... thats because hes over in NSW fighting the fires, thats right Hugh has put something else in front of a blitz truck and for those that know him thats just well......a miracle.

Hi all.

Would just like to know what the best thing is to flush out the diff. I am not going to take it apart so i was hoping either diesel or thin oil would work the best. Also is there any danger taking the booster apart?

Hi Shane

Concerning flushing the differential are you going to remove it from the axle or try and do it in place?

Trying to flush in the housing has some issues as you probably guessed of loosening dirt and gunk up but with out really not getting it out of the housing and having work into the axle bearings. When I first restored my HUP and C60S years ago I flushed the differentials by draining the gear lube and refilling with a 50/50 mixture of kero and gear lube and then drove the thing up and down my drive I think all this did was flush out the old lube because it really didn't come out with much stuff.

On my C60L and recent HUP overhaul I pulled the differential units and really cleaned them. One thing I can say about trying to clean the housing and the gear units is the only way to really get them clean is with real hot water or steam. I used Gunk to really loosen up the old gear lube, then washed them with 170F water.

Concerning dis-assembly of the brake booster, do you have the manual? Don't try without it and pay particular attention to the actual valve assemble very easy to damage. With care you can take these apart clean and reassemble without problem. Checking them on the bench for leaks is much much easier than installing in the truck. Look/listen particularly for leaks around the piston barrel.

Cheers Phil

Hi Phil
Thanks for your advice mate i have just put the wheels and axels back on so i wont be taking the diff apart this time. I have drained the diff oil and you could stand a stick up in it however not to much grit. So just boil water and pour it into the diff? Do i have the bottom plug in then let it drain or allow the water to run right through? I dont have a manual for the booster im thinking i should send it away to get fixed, Hugh Davies has a mate who sent us the booster i dont know if he is part of the MLU clan hope he is so i can thank him. Thanks again Phil
