Cam bearings on the feed intake rotor need to be replaced every season. A cam bearing costs around €25 plus VAT. It is also important to check the pickup chain; while this won't need to be replaced every season, it still needs to be checked for wear. If it looks worn, go ahead and replace it to avoid downtime midseason. A new pickup chain costs around €150 plus VAT.
In this picture you can see the feed auger just above the intake rotor. This baler has about 16,000 bales made and, though some wear is now visible on the auger, it doesn't need replacing this season. You can also see some pickup tines - replacement tines cost about €3 plus VAT.
One thing that must be changed each season is the gearbox oil.
As can be seen from the picture, the bung on the gearbox on the Fusion 2 is more accessible than it was on the original Fusion. No check in this area is complete without mentioning safety - if the PTO shaft cover is anything but perfect, it should be replaced.
The knives need to be taken out and sharpened, while any cracked or broken knives should be replaced.
A new knife costs about €25 plus VAT. Roll pins on knives also need to be checked as they too can break (though McHale made an improvement on the Fusion 2 by increasing roll pin diameter from 10mm to 12mm). A replacement roll pin costs about €1.
Check the chamber rollers and bearings for movement. Run the baler for 10-15 minutes before servicing. This will help to clarify what needs to be replaced (as opposed to maybe just having a rattling stone stuck in the chamber).
It is a bad sign if rollers are screeching for long periods as they rotate. An automatically greasing baler costs a bit more, but tends to prolong roller bearing life because dirt is pushed out of the bearings by the incoming grease.
Keep a spare cartridge of grease in the tractor at all times. A cartridge will do for about 300 bales and costs €2.50.
A good supply of grease will act as a preventative measure for the likes of roller bearings as the grease pushes out dirt and grime from inside the bearings.
