Printable Version of Topic -HD Forums +--Forum: Boat Tech +---Topic: Dominator lube question started by Havasu Doug Posted by: Havasu Doug on Jan. 27 2003,4:16 pm I have a Dominator jet in my '78 Challenger. I think it's a model 12S. Anyway, there is neither a lube canister or Zerk fitting to lube the thrust bearing on it. Has anyone installed one themselves?   Posted by: miller19j on Jan. 27 2003,7:22 pm Doug, I have never worked on a Dominator so I am no expert by any stretch of the imagination. But I did stay at a Holiday Inn Express once. According to my jet pump rebuilding book both the 12S and the 12TD have a jet lube canister.  It should be located on the front part of the suction piece around the bearing. If you are looking over your transom at the jet it should be on the Right side. If you do not have a fitting or a lube canister there should be an empty threaded hole there. The 12S has the hand hole in the boat and the 12TD has the hand hole outside the boat.

Posted by: miller19j on Jan. 27 2003,8:53 pm That seems strange that it doesn't have anything. Does it look like it was filled in at one time? I find it hard to believe that they originally made it that way unless they are using a sealed bearing that does not need to be lubed. I would give dominator a call on that one. And yes we are reading the same book. But don't forget that I have stayed in a Holiday Inn Express!

Posted by: miller19j on Jan. 27 2003,9:23 pm That's no fun you can't sit in her and drink beer when you are bored.   Posted by: Havasu Doug on Jan. 27 2003,9:42 pm ---------------------QUOTE BEGIN------------------- <000000'>That's no fun you can't sit in her and drink beer when you are bored.   -----------------------QUOTE END-------------------- When I rented a duplex, I stored her outside next to the garage.  I sat in her many days and nights thinking about the river, while drinking beer and listening to the tunes. When I rented a home and at the home I owned, I did the same thing while she was stored in the garage.  This house has too much in the garage already, so she's stored remotely. Posted by: miller19j on Jan. 28 2003,2:48 pm Doug did you get this figured out? Posted by: Havasu Doug on Jan. 28 2003,2:57 pm ---------------------QUOTE BEGIN------------------- Doug did you get this figured out? -----------------------QUOTE END-------------------- Yeah I got some good news today.  Thanks Miller.  When I visited Miss American Pie in her temporary quarters, I found a fitting. I was dark and I didn't have a flashlight with me, but I felt where the fitting should be and it was there. Posted by: miller19j on Jan. 28 2003,3:02 pm Now you need to put some Grease in it! It sounds like it has been a while since she has been lubed.   Posted by: Havasu Doug on Jan. 28 2003,3:15 pm ---------------------QUOTE BEGIN------------------- <000000'>Now you need to put some Grease in it!

Posted by: JustMVG on Feb. 01 2003,2:42 pm Just what type of lube do you use for the Dominator, i have to do some work on mine a 128? or 12S A, is it a grease or like the Berk's gear oil.

Thanks Mike VG -----------------------QUOTE END-------------------- My Dominator is a model 12S.  The only text reference material I have on it is "Marine Jet Drive" by Seloc Publications.  It calls for "an extreme pressure high temperature moly disulphide grease, such as Pennzoil 704, Kendall L-424, or equivalent".  "Multi-purpose" grease is NOT to be used.  I'm going to look into getting a "lube cannister" for it, too, because mine currently doesn't have one. end
