Greasebanks on chippers, a good idea?

[Mick Dempsey]

I have a Forst st8, great chipper blah blah.

 

Anyway I'm very keen on maintenance and try and keep all my machines running as they should.

 

So I keep an eye on everything and noticed that at least two of the pipes have split at the back of the bank.

 

I've traced them to the roller bearings which from the outside look like the have grease for the moment, so no panic.

 

I don't trust 'em! I've checked that the two main bearing supplies are functioning.

 

I'm an owner operator so keep an eagle eye on stuff but you could be pumping away thinking you're doing the right thing and all the time it's running dry.

 

I'm going to contact Forst after the weekend to see if I can put nipples on the flywheel bearings at least.

 

 

Picture of the two pipes.

I've a TR6 and am considering removing the central greasing bank also, because like you I don't trust it either! Mines not that old only ninety hours so nothing split yet, but it's only a matter of time.

Love the convenience of them, but our lads had been pumping grease into thin air for an unknown length of time recently. Okay if they're visually inspected frequently as they're convenient and easy to use solo.

 

I'm fairly sure that it's a straight swop for a normal metric nipple onto the flywheel bearings, I think (may be wrong) that the bank has a fine thread but not the other end.

The pipes usually don't give any trouble but going at it a bit too hard can cause splitting.

 

Most lube work happens before work and before the machine is warmed up, try greasing when the chipper is warmed up, failing that there are semi fluid lubes available that are less viscous and less likely to cause problems but speak to the manufacturers about intervals

 

The plastic pipes are a recent thing, in days of yore they were steel and if you are willing to pay for the extra work, they can be again.

 

Swapping to a nipple on the bearing is as simple as can be, you could probably take the one off the remote bank and put it into the housing.

Ok, I'm not alone then. I'll defo change the ones on the flywheel.

Think jensen went to high pressure pipes on the grease bank, my be some thing forst need too look at.

Bit of a shocker on the R&D front since the remote bank is supposedly a "plus" selling point for convenience / ease of dailies etc.

Thats the way to go Ian, the long flexi rubber ones like a hydraulic hose,fit and forget. Those plastic pipes are only good on static kit inside factories, not good on kit outside in the elements that are rattling themselves to death.

We took two off our QuadChip when we made it easier to get to the nipples. Cannot see the point of remotes when access to bearing is good enough to go direct!

[Mick Dempsey]

Too right Pete, plus you can feel/see the grease get where it's needed.
