Chainsaw Repair

Oregon is introducing a new line of lightweight 'professional' guide bars.  As I understand, they are laminated bars with an aluminum core, and no sprocket lubrication holes (big change for Oregon).  No RSN models planned.  Available in 'Spring - Summer 2016'?

(Quoted from an Oregon Rep - edited for length.)

"These bars use completely new sprocket nose assemblies which are designed to outlast the bar rails. Our lab testing and field testing . . . have confirmed this.

. . . the nose shield is packed with grease at assembly and its purpose is twofold: 1) it keeps the grease in the nose while still allowing the bar and chain oil to enter the nose assembly for continual lubrication and 2) it prevents debris from entering the nose and causing wear on the nose components. So there will no longer be a need to add grease to the nose as long as you are using bar and chain oil.

. . . the new design(s) also feature our LubriTec system which has an angled oil hole at the tail that increases the velocity of the oil that is delivered to the chain and bar for better lubrication.

. . . these bars will eventually replace the Pro-Lite family.

- 'SpeedCut' is a narrow kerf (micro-lite) bar . . . for use . . . on saws up to 55 cc

- 'ControlCut' are standard kerf bars (.050, .058 and .063 gauge) with small nose radius which helps prevent kickback . . .

- 'VersaCut' are standard kerf bars (.050, .058 and .063 gauge) with large nose radius which are suitable for use in a variety of applications."
