This is a brief note to cover proper lubrication of the 300 reel. All too often reels come in for service that are stuffed with grease. A lot of the time the grease closest to moving parts has dried, and hardened.
There is no need to pack the gear box with grease. A thin film of grease on the gears and bearing surfaces is all the grease you need. Application of a good reel oil occasionally ( we highly recommend ReelX ) through the oil port in the back of the reel, and into the drive gear shaft ( on most versions ) with the crank handle removed, is all that is needed to keep the grease soft, and the reel properly lubed.
We sell bottles of ReelX for 5.95 plus shipping.
