Ok, so why are people ending up changing bearings every 40 hours then???

 

Are they?

 

Last few i changed bearings on had done 900+ hours and barely been greased or maintained.

Shouldn’t make any difference if blades are not sharp
These sub 750 machines are not built to last

Let me give you some advice... Timberwolf have not got a CLUE when it come to looking after their own machines. When it comes to belt tensioning, they just pluck a figure out of the air.. Take my own 13/75. I have two copies of the makers manual here. One gives a tension about TWICE as tight as the other one, and all for the same machine.. They have not got a clue sad to say... Needless to say, with the belts too tight, the bearings are not going to last very long..

Think you're about 10 years late with that advice, looking back in the thread. Be interesting to know what did happen to the chipper in the end though.

No need to buy a sub 750 now😄

That's one person.

 

Also makes me think they were installed wrong or not greased. Also said after 40 hours, not every 40 hours.

Damaged pressing them in i would think?? An idiot once fitted a car wheel bearing for me [before i had a press] Lasted about 1000 miles... Pressed the thing in by pushing on the centre i would think..

 

Bet they are not fun to fit either..

Mine lasted 12 years till I sold it, probably still going strong.

Older sub 750s still fetch strong money.

 

Whether they are built to last or not, they clearly do.

I'd strongly disagree with that statement and know plenty of chipper mechanics that would too but never mind.
I'd also say it's down to who does a bearing replacement and it they replace other worn parts and actually know what they are doing is the key to longevity.
