MS460 H.O. Oil Pump

[Swamp Yankee]

Not a lot of experience with Stihl oilers

Friend of mine bought a MS460 a month ago with a 25 inch bar. His chain was running pretty dry and the bar was discoloring when he was in big stuff. I showed him how to adjust the oiler, we turned it all the way up. It's better, but still seems like it's not putting out enough. I had the same issue when I bought my MS441 C-M a few weeks back. The dealer popped a high flow oil pump in and it's working perfectly.

Anyway never having played with the oil pump on a Stihl, are there any issues with swapping one out? I've done a couple of Husky's over the years and they're pretty straight forward, but if anybody has any helpful hints I'm listening.

By the way, the dealer he bought it from has never heard of a high flow oil pump, so that leaves two choices, I can do it for him if it's straightforward and won't void his warranty or I can take it to the Stihl shop I frequent and have it done. I'm assuming as the stock pump is working as it should, similar to my 441, Stihl won't pick up the tab.

Thanks in advance for any and all help.

piece of cake.

remove rim, drum, clutch, cover and your there. put back in reverse. clutch is reverse threaded. stihl torque spec is 50 Nm on the clutch.

edit: also remove brake band.

That's what I was hoping for.

What kind of bar? Stihl ES bars are "discolored" along the rails from flame hardening. A lot of bars have that under the paint...

Rep sent for this info. I know mine with a 28" bar is light I think on oil. Might try the upgrade as you posted.
Thanks

 

[blsnelling]

yes, also fits ms440

Those parts will not fit the 440. It has a different pump.

your right. pump piston is different. but the control bolt will work. pointless without the pump piston thou.

Be for you spend the money on a HO oil pump.

Have you checked that the existing one is working as it should?

When was the last time you checked the oil pick up, tank pump etc.

If that is all good and you need more oil then check out modifying the oiler.

there are some threads, mods on how to increase oiler output while you have it apart.

[wigglesworth]

I just mod the existing oiler. Easy peasy to get em pumping like the Exxon Valdez. There is a thread here somewhere...

Edit: this isn't the thread I was thinking of, but along these lines.

Hi All
This problem can be avoided when buying a new Stihl pro saw if you buy the ( R model saw ), it comes with the HO oiler from the factory plus 3/4 wrap top handle / the large dual dogs / over sized clutch cover with roller chain catcher and extended chip deflector, well worth the extra $65.00 premium.
Safe cutting
