TW190 rollers

[armchairarborist]

noticed the bottom feedroller was way over to the left and starting to gouge a circle in the housing, pulled a couple of bits off the machine to investigate and found some polyprop rope/string round the rollershaft on rhs, removed it and refitted but the rollers were central until i greased the nipples then they jammed hard against the left hand side, levered them back a bit but they seem biased to the left now, ran machine to make sure its ready for tomorrow but they still seem to sit to the left a bit much, will it be ok to use?

 

oh the rope must have been in the last load of branches last week or we would have noticed it sooner.. thanks Ed.

Hi Armchairarbourist

 

Thanks for the pics they are most informative.

 

From them it appears that you are using a graphite based grease, this is a big NO NO, as graphite acts as a grinding paste and will wear your parts away, please use a mulit purpose grease at all times on the chipper.

 

It is not uncommon for the roller to be pushed to the end when grease is applied, but if you run the machine for a couple of secs then regrease then run again and by performing this action a couple of times the grease will run and even itself out in the cavity.

 

You must check that the bearings have not been damaged by the twine getting jammed, when the unit is isolated try moving the bottom roller and if there is more than 1mm of play your bearing will need checking.

 

The gouges in the rollerbox side has been caused by the twine, it would be safe to use the machine but be aware of debris wrapping itself around the extra space.

 

Hope that this help

 

Regards

graphite grease? must have been previous person who greased it as i'm on regular grease, only bought machine from orange plant (york) in december 2009, looks like i'll be removing all that grease now and set to worry about the damage already caused by graphite grease then..
