Getting used to no synchro on 1st and 2nd and can start in 2nd even pulling the trailer. Clutch is a bit heavy but works well. Get used to it.

Yeah! Good to hear! Other than the synchro...

Now the gearbox has proven OK I can bolt the other bits back on.
I am leaving the bottom chain drive PTO off however as I am trying to source an Isuzu hydraulic PTO to drive the winch. I understand they will always drive in one direction even if reverse is selected which is not the case with the pump on the bottom PTO on the T,box.
For those that have not seen a third axle drive here is a photo.

Be interested to see how they get around the pump running in reverse. The transfer input is already running in reverse so the pump will be running backwards unless they get really funky.

Time flies. Cant believe it was 2011 I did that.
I have been running around without the winch connected all this time.
OK now I have decided to leave the bottom PTO off and have an Isuzu PTO with Hyd pump I can bolt to the MSA. This will allow me to run the winch no matter what gear I am in and even reverse.

Most truck pto's run off the reverse gear on the layshaft, hence why they will run in forward or reverse!

How have I missed this thread! Yup, same here.. Have the truck box PTO that came with it, which also has a large hydraulic pump.. Ideal for big under floor hydraulic winches!

Well its all in.
I had to move the oil tank that was inside the chassis so I could get the PTO in.
Winch rotates but I still have to set the pressure relief valve and make up the linkage for the PTO and wire up the switching solenoid.




Also determine if I have to overwind or underwind the cable.
It was a tight fit as I had to grind a bit off here and there

I also had to make a spacer from 2mm alloy to put under the PTO as a shim. without it the gears butted up without letting the PTO meet the box.

Put an AGM house battery where the tank was and moved the tank back a bit.
Not much room under a 6x6.
