I have an American Turbine AT-309 in my boat with a droop and Place Diverter, there is a Thrust Bearing and Bowl Bearings, how often should I be greasing these? Someone told me to grease the Thrust Bearing every time I put the boat in the water and grease the Bowl Bearings twice a season. Can anyone confirm this for me? Also the same person told that I can use the same grease in both of the Pump bearings that I put into my trailer bearings? I want to make sure I am doing the right thing, especially since I had to completely rebuild the pump at the beginning of this season. Any info would be very much appreciated.
Barry the recommendation (A/T) is to grease every 30 hrs of operation or if the jet/boat "sets" for more than two months , recommended lube is "EP" (extreme pressure grease with moly (we use the A/T grease or Valvoline . Overfilling /overgreasing (much more than 2/3 full) the grease/bearing cavity can cause the bearing to run hot not to mention making a mess . One of most common causes of brg failure is moisture instrusion BTW. Tom
Thanks for the info guys. It seems that I am over greasing the pump by doing it each trip, once a month or every three trips should be more then sufficient. Tom, where can I buy the grease that you use? I have been using the wheel bearing grease and after reading the AT manual it specifically says do not use wheel bearing grease. Should I flush the bearing somehow when I put in the new grease? Again, I want to thank you guys for the great info.
The red Mobile One synthetic grease is the shiat!!
The ONLY grease that will hold up on the axle splines/caps on a Sprint Cup full floating axle (especilay in the old rear camber days).
Most teams either take it out of the tube or cover the tube with duct tape to hide it from their oil sponsors (did I just say that?)
