Timberwolf 230 DBH In feed roller not working

[wood cutter]

Hi all.

 

After some advice. We have a at timber wolf 230 dbh diesel wood chipper, which has started to play up.

 

The in feed function of the rollers has stopped working?? The reverse  roller works however nothing happens when you press the in feed button.

 

Have changed the fuse and relays in the control box, however the h box is showing a speed fault ( not sure if the light should illuminate when at full chat?) do you guys have any other ideas as to what it could be?

 

Have also taken the control switch off the side of the machine one side and everything looks connected as it should, also have chase the wiring loom to the connection plug and all seems OK there?

 

Or does anyone know a decent plant mechanic? I am located in Birmingham and any advice would greatly be appreciated. 

 

many thanks

Initial thoughts, is it running fast enough?

I'm not familiar with the workings of the timberwolf but is the engine reaching sufficient rpm? The feed rollers on other chippers with stress control will not feed unless the engine is running fast enough. Also some machines sense their speed from the alternator and if the belt is slipping it will not reach speed.

Beat me to it

the throttle cable has stopped working/gone veryu slack and needs replacing, so i slipped the side cover off and held it down to rev it up to full chat, it worked but as soon as the stress came on it wouldn't go again, 

 

It was also showing a speed 2 fault (light illuminated and not flashing) on the H box??  could it just need the throttle cable replacing?

‘Puter might need to reset, same on my Schliesing when I replaced the throttle cable.

But I’m guessing now, you need an expert.

Twas that piece of shit stop bar switch for me when mine stopped working.... they let water in and corrode like no one's business.... this means no power to the fwd button to allow rollers to work .

 

 

Glad I don't own one now

We’ve had this happen a few times .

Once it was water in the connection in the wiring loom going back to the stop bar and forward/reverse.

Another time it was the bi-directional solenoid valve. Try swooping the plugs and see if rollers will work forward but not reverse. IIRC there are little lights in plugs to show if they are getting power when you press button.
