A BIG " THANKS" to the Vortex and Aerotech Owners
Jeff, Scott has it right. I have only owned 3 blowers in my short career. A 47, 68 and 6008. The 47 and 68, had and have plugs with a HOLE drilled in them to release the grease when it's running at speed and temp. The 6008 has a fitting with a spring loaded plunger to release the grease at a specific pressure. I had removed them and cleaned them ( they weren't plugged up) when I realized grease was not being released (I was wondering, where is the grease going). No mess to clean-up, nice but not good. The grease was bypassing the shaft seals and building up in the chamber. My guess is that on one cold day the blower was just not going to turn do to the build up. So I pulled it and replaced it with my rebuilt 68. This is going to cost around a Grand, plus down time. I will have them replace bearings also. The blower was only in service 4.5 years.
I was curious if all 6008's have these and if anyone else has experienced this problem. My thought is to replace relief side with hose barbs and clear plastic tubes, that will go into a can and catch the expelled grease. Voila: no more mess and hopefully no more seal problems. CB. PS I post this knowing Marty will not be reading it.
