660 needin more oil on the 36" bar

[TexasTreemonkey]

Hey i got a 660 pulling a 36" bar. I got the oil turned all the way up and it still dont oil like i want it to (there is still over half a tank of oil per ever tank of gas). Maybe since the 36" is the biggest bar its suppose to run i could c that but what do people do if they put on a bigger bar? I know several people that run 44s on thier 660s. Can you drill that little hole out on the bar?

there should be less than a half tank left in the saw at fillup...Lakeside did a thread on here one time about upgrading to the HO pump that is on the full wrap saws...nothing too hard to do..i don't believe it was too expensive either

You can only do it with a full wrap bar??? why does that matter?

 

[sILlogger]

no no no....the full wraps come out of the factory with a HO oil pump..so if you have a half wrap and need more oil you need to upgrade to the HO pump

you can drill out the bar but you need to use a drillpress and lots of lube the bars are made of hardened steel you might need to grind the drill at 15 to 20 degrees less than normal. The guys who mill are the only ones I know of that do it.

an end mill bit would work good to...since it is flat across the cutting face

no need to research a different saw..just upgrade the pump..or if buying new have the dealer upgrade it and pay the difference in parts

Drilling out the hole in the bar will do little for the oil flow. The pump upgrade does.

+1, the only bar ive ever did it on was an ArborPro that the hole wasn't big enough
