KH 41 wont start

[Hambo]

Not sure, you need to check the levers and blade control, if its trying to lift when starting the definitely something not right.

I think your machine is linkage controlled rather than servo. So id have a look at the linkage etc to start with

Yes it will be linkage I would expect she is 1996 model KH41, I will just have to wait till I get home and lift the floor and see what linkage is stuck or out of line, but thanks for all the pointers, makes me feel a bit more optimistic.

Sorry I may have given you the wrong impression, the boom will lift if you engage the lever whilst the starter is turning the engine over

That’s normal. You’re turning the pump over with the engine.

Although he never started it he said that it offered to start when he put the track levers forward ? So still the same problem ?

Thanks for info, what could have done that as was working fine until I parked her up for the night?

trodden on a pedal, getting off perhaps??

Yes I definitely did that and heard the revs change when i got out the cab, so I flipped the pedal the opposite way to get revs back to normal, but never noticed the change back, the machine was still running fine so I carried on working then I tracked her back to the barn and laid bucket to rest and shut her down…
The rest is history…

Yes its very frustrating being out here and cant get the floor up for inspection, but thanks for getting back with all the replies, just gives me confidence to try and find whats wrong!
My brother has offered to have a look but I said I would rather wait till I got home.
So thanks again.
Hamish.

Has it got high speed tracking (and if so so is the button stuck)?

Here is a crazy idea. Why not buy a service manual? I know it's cheating, but even people with great mechanical aptitude begin life with no actual knowledge. And some manuals are fantastic. I firmly believe every technical writer should have to read the Detroit Diesel 71 series manual to see how it should be done. Course that was written during WW2.

A manual is a great place to start, but not a substitute for someone who has 'been there before'.

[Mogman]

explain how the dead man isolates mechanical controls then please Aiden??????

On my Komogsu there is a little spring loaded hydraulic ram that locks the travel levers and needs pressure to pull the ram back to release the levers

 

[Mick-the-fitter]

KH 41 all mechanical controls as I remember, so could be a stuck cable or lever! Before starting or trying to, move all levers fully in all direction
