Re: thwaites 4 tonne year 2000 forward & reverse spool valve

Try cleaning up ALL the electrical connections and try what has been suggested by kaos, that is a simple and safe test. If you get the result from swapping over the terminals then you need to look at the linkage that must move to make the solenoids switch on and off. So check there is free and easy ...

Re: thwaites 4 tonne year 2000 dumper wiring diagram

That was definitely a dirty contact inside the switch. For your forward and reverse issue now you will need a multimeter but if there is a switch connected to the forward and reverse lever/foot pedal I would guess that is the problem child. Find that switch and drown it in WD40 or similar and make s...

Re: Petter PH1 difficult to start

Just as a bit of help in the future. When I change rings I actually use my ring compressor to help with the removal and fitting of the rings to the piston. When removing I slide the compressor down to the top ring and tease the ring up onto the outside of the compressor then slide the lot off. Repea...

Re: thwaites 4 tonne year 2000 dumper wiring diagram

Never assume anything mate as it will make an ass out of u and me. Grab a spare relay and start to swap them about but new parts can and do fail so check everything methodically. I had a relay in my 9 ton truck misbehave and it was not working and by accident I dropped it as I was pulling my arm out...

Re: thwaites 4 tonne year 2000 dumper wiring diagram

G'Day smarttee. The wiring for these dumpers are very simple and straight forward. Look at any wiring diagram to find out how it is done. Basically there is a main thick battery cable going directly to the solenoid. Power from the battery or voltage regulator to your ignition switch then your igniti...

Re: Petter PH1 difficult to start

Sounds like you are having fun with this challenge. The 0.060" over size could have been done at any time in its life but yes it has been bored. When you had the barrel off did you think of checking the ring gap? Check that both valves are not sticking slightly open. Next is the fuel system. Do...

Re: Dumper identification

I took out a fair bit of slack from the Bishop steering box on my Liner by welding up and grinding the pin back to shape. I like your one too it is a real gem with Family history.

Re: Dumper identification

Quite possibly it is Whitworth and they have a 55' angle thread, if not then maybe SAE with a 60' thread angle. TPI is the next thing (threads per inch) and this will confirm the thread size when we know the angle. May be have a Google search for a thread chart online then using a metal rule count t...
