I have a Stihl KM130 Kombi with the older(good) HT-KM pole saw head. After 5 years of continuous abuse the bearings in the saw head fragged. The shrapnel ate the oil pump too. It looks like I may be able to "save" it by replacing the driven shaft bearings. Stihl PN# {inboard, sprocket end} 9503-003-5190 (6001-2RS) and PN# {outboard} 9503-003-5860 (609-2RS) are about $20 US Dollars each locally, but only about 10 British Pounds ($13 US) each from L&S Engineers. Apparently Stihl platinum plates each US part...
Anyway, I will source aftermarket bearings at about $5 each and reassemble to check the gears for livability. If that works, I'll replace the oil pump and add a couple fill & drain screws so I can run gear oil instead of hoping that the grease happens to find the rubbing surfaces.
The US techs all hate the new saw heads; they said that Stihl is going to revert to the older style this year.
Wish me luck...GM

Hi Green Man, and welcome to TGMF.  :tup:

Must admit the new pruner attachment seems a bit Micky Mouse build wise compared to the older ones.  The castings are ultra thin a don't look very strong, almost looks like it was designed specifically for a battery machine.   

So I don't blame you for trying to resurrect your old unit.  ;)  Let us know how you get on with it.
