chipper rollers

[Gavin]

hi guys

my little tw125's twin rollers started messing about yesterday

advice please

was not pulling 4in+ stuff in only every now and then ? could it be this lovely weather got in the control box ? or maybe the belts to hydraulic motor slipping ?

havent had to do anything to this macine since owning it ?

should i get it looked at before anything goes bang.

i remember reading a old post about throttle being fully opened and checked it

help and advice appreciated

on our pto tw, we had similar prob, it turned out to be the relay vibration, theeres two relays one for the two paddles for feed and reverse, try swopping them round might cure it - but not sure if yours has electrical relays on them

If the other fixes don't work, you could try bypassing the stress control and see if they continue to do it. I had a similar problem with one of these machines, and it turned out the flywheel axle was scored as a result of worn bearings. The bearings must have a very tight interference fit on the flywheel. (I'm not sure if it still the case as I moved to Greenmech as a result of this, but you never used to be able to grease the bearings as they are 'sealed for life', which unfortunately let down what was otherwise a very good little machine). This slight movement threw out the stress control sensor's ability to sense the flywheel spinning. If the disconnected stress control cures it, this might be your (unfortunately rather expensive) problem. If you suspect this is the case, slacken all the drive belts and try and coaxe some lateral movement out of the flywheel pulley with a pry bar - if it moves at all then you'd better get your cheque book ready...

Hi Gavin

Sorry to hear that you have got a problem.

Some simple checks to make are

 

1. Ensure full throttle is established in operation mode

2, Engine revs should be around 3400 rpm

3, check drive train belt tension - shouyld be very tight

4, check hydraulic belt tension - should be tight

5. check in line hydraulic filter is not blocked, and condition of hydraulic oil.

6, check air filter is not blocked

7, Check that the speed sensor for the no stress system is set as close as possible to the trigger wheel without touching

8, check SRB500 relays are OK and connections to base are secure.

 

Further checks can be carried out using the no stress bypass but before you do this please contact me for the safe operation of what to do.

 

Tel no. 01449 765820 during office hours

 

Hope that the above cures your problem but call ifyou need further help, if you call please have the serial number of the unit available as I can look up the database for the unit for all the settings
