Timberwolf TW190 flywheel bearings

[Treemover]

Chipper is making a right noise and have ordered new bearings, is it a big job? Ive changed bearings on stuff before so hoping this wont be any different. But would be great to get some advice and tips from anyone that has done this?

 

Im thinking we chipped those bloody Cabbage Palms Cordyline australis way back and that did the damage as it blocked the chipper and problems started after!

Bob, your a star; thanks for that, should be able to manage that; I'll bring to a engineering shop to press off and on bearings. I think its worth being able to fix our own stuff; as its a great skill. 

That big nut, I have a torgue multiplier, so if I get the socket, I should manage it!! Thats a fair weapon you have there!! Thanks again, Drew

Is there a way the post @aspenarb has pointed to can be tagged with #timberwolf #bearing #replace or some such that a search would find? As the thread title is not a help here.

First pic, I think I need a flat 24mm wrench! Cant get it with current one

 

second pic, which way does this come out, engine or hopper?

Just to update and incase this helps anyone; the flywheel will come out without having to remove the top cover; so hats off to the engineer;  going to try get bearings pressed on and off tomorrow. Def play in one of the bearings; just hope its the bearings and not the shaft.

Have to say; it’s not the worst job; I had to get bearings pressed off and on; and is a great lesson in how to deal with other issues such as tightening belts etc. 
 

was def bearings as knocks and vibration gone. How long these bearings last is anyone’s ; prob not as long as it’s my first time; 

 

with the amount of bearings I have in kit; Im looking at a hydraulic press.

Well they didn't get it right with the 150, half the chipper has to come apart to get the flywheel out and then the piddy bearings off!
