View attachment 64514This is the only solenoid we can find but think it’s to do with the safety cut off switch when you lift the left joystick arm

Show me offset ram!

 

[Graham]

looks like your rotary coupling taking oil to the tracks and blade with presumably return circuits/second services also
follow the hoses from the offset ram to the change over valve - should be the easiest to follow

I think we may have found it under the seat. Seems to have 6 pipes and a solonoid on it. Think we might be getting somewhere Chaps

Sounds like you have found it
It may have an override button on the end of the solenoid that you can push with a small screwdriver

Apart from that! Put a live and earth to it, after engine started and operate slew

In that picture top and bottom live or earth, the one to the side don’t use a that

It’s getting exciting !! Thanks for chipping in

If that is a 6 port valve, there must be another solenoid opposite that one to drag or push in the opposite direction!

Too dark to work now guys will start again in the morning. Will read through all your replies over a beer and restart in the the morning thanks for all your input so far

not if it's a 6x2 diverter Mick .....
one set of ports will be default (say C + D) and the other set will be when actuated (say E + F) ..
twin solenoids'd be a Cetop double acting valve

6x 2 diverters

3 x 1 diverter

cetop

Nice set of cetops

 

[V8Druid]

Nice set of C cups

fixed that for you

 

[Mick-the-fitter]

Agreed couldn’t see the left side in the pic!

 

[Graham]

Thanks guys, I’ll clean the crud off in the morning and try to take some better pictures. Theres 24 years worth of oil grease and mud in there.

 

[Graham]

You guys are absolute stars. Broken wire and a blown fuse going to the solenoid on the diverter valve.
