The most overlooked place that has to be greased on a Chainsaw is in a place that most people overlook mainly because they don't know about it and where it's at. The inner needle bearing that is on end of crank shaft that is part of the clutch assembly.I have seen many that were bone dry and probably had no grease since the saw lett the factory. Now I will tell you where to access it and this may surprise you, first and foremost it is hidden from plain eyesight. To access it you have to take the clutch cover off just like you would if were going to change bar and chain, now look at the end of crank and to will see a hole, that hole is there so you can pump some grease in it so your needle bearing can be greased, you use the same grease on it that you use on the end of your bar tip, using same applicator. Hope this tech tip my help someone.
Agreed that the clutch drum bearing needs attention (I personally grease em, there's debate about it, though). I'm curious about your way of doing it. Hole in the crankshaft? What brands?
Most ,not all, saws with an outboard clutch can be greased as described above . About the only saw that I'm aware of with the inboard clutch that can be serviced like that is the 390xp . More than likely a few others .
Yes I grease my clutch bearings some of my Husky's have the hole in the shaft and some I have to remove the clutch to grease them. It doesn't take much , the only time this bearing spins is when the saw is at idle
Not to hijack ,or derail the op's post . But one thing that might well have been added to the list of what to do when servicing the clutch bearing is to look at the rim / spur sprocket for excessive wear .They seem to suffer more abuse and neglect than even the clutch bearing does .
I grease mine but every time I pull the drum, the grease is gone. It never seems to stick around for long.
