chainsaw clutch drum needle roller lubrication?

[David Heaf]

If anyone wants a clean Dolmar 123, I have a nice one ready to go and looks low hours! It wont break the bank.

 

I'm the grateful recipient of this clean machine. Many thanks!

No worries, it is in a very clean state, you should put some pics up to piss everyone off:lol:

I've got a still MS261 as my main saw and after reading the horror stories about their needle bearings, I took it apart.

 

The failing needle bearing - part no. 39 in your diagram - should be lubricated. Apparently it's a common failure on 261's so it's either because the spindle oscilates or poor maintenence. So I got some ZX1 grease, which I consider to be the finest there is, and put a smear on the spindle and some inside the bearing and some on the outside too. Put it all back together.

 

At the same time, I dressed the bar, did the usual inbetween jobs/service and the difference is mega. Engine off the chain just spins around - you only need a good pull. A huge difference in performance.

 

And why not? There's more to chainsaw maintenance than pouring chain oil in.

It is surprising the amount of guys that want the most performance from a saw and send it in for porting and the first thing I find is a bunged up airfilter:001_rolleyes:

 

Guys......run 100 yards and then, when recovered, do it with an oily cloth over your nose and mouth and understand what I am saying!!!!

Always amazes me how little attention some people pay to air filters: it's basic DAILY maintenance! (Twice a day if we're felling Norway spruce or similar)

Ah, but they probably already know that finding spares for an antique Sachs Dolmar is getting harder and harder.

 

As Makita supplies only plastic cage needle roller bearings, I eventually sourced a metal cage one that fits (NTN Needle Roller Bearings (Japan)) from the stockist in Germany mentioned in my earlier post.

... and four times a day if you are milling
