Oil Pump upgrade, Part 1

[tawilson]

There was just another thread going on that and I believe the result was the 044 and 440 did not have a higher output oiler available.

Yes, BUT, I was wondering if these HOutput parts from the 460R pump would fit into the 044 pump...I am guessing they would.

Lake is not around anymore but still a good thread...

having trouble with my new MS660 oiling enough with a 36in bar.
already checked everything and nothing is plugged.

does anyone know if USA 660 have all been upgraded to high output oil pumps?

when was your 660 built? upgrade one built aug 2010.

but stihl in their 2009 tech info states its going to install the HO on all 660 but no start serial number mentioned.

On the IPL there is a HO pump labeled (AUS). That's the HO pump. You can also get the individual parts to upgrade.

these two parts were $60 at our local Stihl dealership

1128 647 4802 New Control Bolt
1122 647 0602 New Piston

I don't remember what was how much but the total is right around $40.00.
