Timberwolf TW230 tracked chipper feed roller problems

[vdubber79]

Hi, recently bought a 2003 TW75 230H tracked chipper and often when the rollers get jammed/ you stop them / or move the chipper and go to restart the blades they won't go forward , the backwards button works fine but forward won't, doesn't seem to be the bar switch I've tried messing with that when it does the problem, only way to get it to work again is to drop revs, turn off the engine restart and pull up revs again, this seems to always do the trick but it's a real pain in the ass! It started doing it today and seemed to do it more often as the day went on . Also does anyone know where I can buy or download the manual for this model

Many thanks

Neil

Anyone ??

Phone TW on Monday morning or put your post into the TW technical section.

Check the relay connections, they are pretty poor to be honest we recently removed ours pulled the female part of the spades from their position in the mount and crimped them up to make a firmer connection. In time we will probably replace the female part of the spades with better quality connections.

 

Hope that makes sense and would be one of my first areas to check, you can do it without taking to much apart by simply removing the cover for the relays held on with 2 butterfly nuts, then whilst the machine is running and the feed rollers not going forward wiggle the relays whilst having someone press the forward button, if it starts feeding that's your fault.

 

Otherwise call Timberwolf they are helpful and will point you in the right direction.

Cheers guys , are the relays under the small cover below the dash panel where starter button ,key etc is ? I heard someone say there's also relays under the forward and reverse feed buttons as well or have I misread ? It's just weird how everytime i restart machine it's ok again. If it was a bad relay connection wouldn't it be doing it anytime and not only after the rollers have been running and stopped ? Either way I'll check it out

Thanks

That's right remove the side panel on the same side as the starter, then it's under another small panel held on with butterfly bolts, there are 3 relays there, to start with get the machine to stop feeding whilst it is running then with the covers removed try pushing and wiggle the relays and see if it starts running again.

If the connection is poor it may start and work fine on restart but the vibration whilst running interrupts the connection and the feed rollers stop, if pushing and wiggling them starts it again it confirms you have poor contacts.

You will then need to remove the relay holder which is held on by a bolt behind the panel and then remove the relays and push out the female spades which are held within the plastic relay mount and crimp them lightly so they make a firm contact with the relay spades.

 

Another way to check the contacts are good is remove the relays one by one and look at the spades themselves they should have clear marks on them where the female part is gripping the male part.

Yes I'm with you that does sound like it could be the issue I'll check them out and hope it's that, I take it both relays are the same for forward and reverse so if it's not the contacts and possibly the relay it's self if I swap them and the problem is now with reverse it must be a duff relay

I am not sure, about switching relays something tells me if one is duff it will send a faulty to the other regardless worth a try though.

Ok cheers I will post up my findings when I get chance to have a look at it

Hi did you find a manual?
