Dominator Jet Oil?

[90 Laveycraft]

I have a 12 TD drive, cannot find any oil port just one grease zert on the side of the front bearing.
Is this the only lubrication the drive has(other than water)?:readpb:

HELLO, THERE IS NO OIL IN IT. YOU NEED TO LUBE THE FRONT ZERT EVERY TIME YOU RUN THE MOTOR, DID I MENTION EVERYTIME". ALSO YOU NEED TO USE RED GREASE IN IT. LUCAS MAKES A AWESOME HIGH TEMP GREASE(RED) AND IT WORKS GREAT. NEVER MIX YOUR GREASE IN THAT BEARING EITHER, ALWAYS USE THE SAME. HOPE THIS HELPS,:skull

Contrary to the previous post, there is indeed lubrication for the tail of the shaft. On a 12TD, you pull off the steering adapter and look into the rear of the bowl. Right in the center you should see an endcap with a zert on it. This is how you lube the rear of the shaft. AT/Dominator uses a double lipped seal which supposedly helps keep the lube in/water and debris out. This provides for less frequent lubrication changes/top offs so you don't have to pull steering adapter off. In theory, if you don't have a diverter or droop on there, you could probably use a grease gun with a long extension on it to get to the zert without disassembly.

Hope that helps,
Chris

Edit:
If AT's site allows hot linking, you should be able to see the cap and zert in the diagram below

Old school dominators do not have a way to grease the internals. It was basically water lubed. When you fired the motor after sitting it sounded aweful until some water got to pumping.

I had to have mine retrofitted/upgraded when I had my pump cleaned up.

You are 100% correct in you statement about the older Dominators. I made an assumption about the relative age of his pump based on the pic in his avatar. It could be a bad assumption, so thanks for bringing that up.

Running the engine on the trailer with the driveline connected is one of those practices that will be debated until the end of time. If the OP has an older setup it's one more reason to disconnect the driveline before firing up the engine. I will always contend that if you have a relatively tight/efficient pump, you don't want to be spining the pump out of water, and that stuffing a hose up the intake, the nozzle or anywhere else is no substitute for an impeller that is loaded properly by being in the water.

Thanks guys - lucky me, the boat and jet are 1990 - 1 zert only(I just checked).
Good input:thumbsup

THATS WHAT I FIGURED ABOUT THE FRONT ZERT! ALSO EVERYBODY HAS THERE OWN IDEA ABOUT RUNNING IT OUT OF WATER BUT IVE RAN MINE WITH NO TROUBLE SO FAR. I HAVE NEVER RAN MINE OVER 30 SECONDS THOUGH WHICH FELLS" LIKE 3 MINUTES, SO ILL THINK YOU WILL BE FINE. IF YOUR TUNING JUST GET IT CLOSE AT THE HOUSE AND DO THE REST AT THE LAKE. THE IDEAL SETUP WOULD BE A "JETAWAY" WHICH BASICLY IS A BREAKAWAY COUPLER THAT YOU CAN DISENGAGE THE MOTOR FROM THE PUMP. BUT" VERY EXPENSIVE AND THERE IS SOME WORK INVOLVED AS THE MOTOR NEEDS TO BE MOVED FORWARD!! GOODLUCK!!

Although lubrication is "prefered" whether it be "oil bath" , grease lube or yes even water (Old school Domy) , all the modern DU/Garlock rear shaft bushings most often used by us in this field are PTFE coated , self lubricating will work with or without added lubrication Tom
