I just replaced the timing cover and oil pump on my '67 GS 400. I packed the pump full of vaseline and even poured about a half of a quart of oil in the filter. I have spun the pump with the drill a number of times but still haven't gotten it to prime. Do I need to take it apart and put more vaseline in it? Are there any other ways to get it to prime? Any suggestions are appreciated.o No:
Are you sure that you are spinning the pump clockwise? Sometimes it takes awhile. You will feel the drill load up when the pump starts to build pressure.
LaMarr How long did you let it spin each time? It could take a couple of minutes to pick up the pressure.
You know it's primed when you see smoke coming out of the drill motor:grin: A good way to tell if it's priming is to take the filter off and spin it. Just make sure you have a catch can.:shock:
I like Adam's description. I used a basic typical 3/8 drill, took one of those drywall-type bits (with the point cut off and filed smooth). I spun the pump shaft for what was probably a minute or so. When I smelled the drill motor heat up I figured it was ready.
LaMarr, if you assembled everything correctly I would bet the drill motor is not spinning fast enough. Mike
I am going to try my plug in electric drill tonight. It spins a lot faster than the battery operated one. More later!:grin:
You definitely need a plug-in drill. A battery-operated one won't have enough torque. Give it all the juice for a minute or so and you'll be good to go.
My 19.2 Craftsman drill did the job just fine, but it's a torque monster. And 18v DeWalt is nice for this too.
Whew! Finally got it to prime. Had to change the releif spring.? The electric plug in drill got pretty hot but did the job. Thanks for the suggestions. :grin:
gear oil Get one of those tall, skinny gear oil bottles. Take the filter off, and squeeze some of it into the threaded tube that the filter spins on to. I have done this before and I think it helps.
Nothing like a good prime job to end the life of a drill...:Brow: When I need to prime a pump, I'll actually go buy a 20 dollar drill. its a one time user, but it really saves the life of my expensive one. I wouldn't say 1 time user, 2-3 primes, depending on your clearances...:laugh: :laugh: ou:
