Trick to getting intermediate shaft out of 340

-
Well, put the priming rod in to make sure the pump is spinning freely..... it's not.

Was gonna replace the pump when I replaced the rear main....but it looked good and had been working fine so I figured I'd keep it... F%#K! I really hate this car sometimes.

Took this one while contemplating whether to shoot holes thru it, or pour a few fingers of bourbon. My wife talked me off the ledge. And I opted for the bourbon. Just kicking myself for cheaping out. I'm and idiot.

Gotta love it!!!
 
The oil pump drives to avoid are the ones that are not tapered at the hex end. The sharp transition from round stock to hex create a stress riser and crack with a hv pump or heavy oil and high rpm.

I pull the shaft out with a magnet after twisting with the screwdriver.

Make sure you are not mistaking normal turning resistance with oil in the pump versus something dragging. When things are primed, the turning resistance is not trivial; I use a large drill to prime with 10W30 oil and 20W50 non-synthetic oil at room temp is gonna make it a bear to turn the pump at any speed.

Having said that, I too would be concerned on the condition of the shaft's interface into the pump gear, so would want to pull the pump.

FWIW, the SBM HV pump gears are only 20% taller than the standard pump's gears, so, as HV pumps go, it is a pretty small increment over a standard pump. Your oil's heavy weight is going to have far more effect on pump torque than the fact that is is an HV pump.

Ya, not the normal resistance, it's grinding and near seized in spots. So, new parts going in! Major PITA...but that's part of the addiction we have right? Good thing is it decided to crap out in the garage and not cruising.

Be well,
Pat
 
Prime the new one by pouring a cap full of oil into the inlet while spinning the pump. Wet will draw oil quicker and with certainty

Hopefully there isn't any debris in the engine could be though more than likely

YES! Glad you caught it there! Wow... Lady Luck was on your side in this one.

If you don't mind, please find the issue and post a pix or 2 so we all can learn.
 
Finally got back in town and got some time to work on the Duster (Side Note: Why do the temps always seem to approach those of the sun when I find time to work in the garage?! Ugh). Came in to cool off and figured I'd post the update. Anyways, I was fortunate to be able to get the pan out without removing the headers, which was a relief! Pulled the pump and found the cause of the failure. The housing that the shaft slips into had cracked and let loose. I am so frigging fortunate that this happened in my garage! Had I not been looking at the oil pressure gauge and notice is starting to fluctuate then go away after I had started the 340 it would have really sucked. Gonna clean up the pan/gasket surface area etc and prep everything now, then hit it again in the morning when it's cooler to put in the new pieces in and button everything up.

Here's a few pics:

Lucky in an unlucky way.
I've got to pull the pan off mine and fix an oil leak. What headers are you running?
 
I've seen it more than once, when the shaft spins like that it always blows up the pump, make it a rule if you change the pump change the shaft.
 

Just a tip for next time, I make a little lasso with light wire. Light enough to bend easily and fit between the teeth. BIG flat screwdriver with the lasso around the shaft, pre-bent to a circle a hair bigger than the gear Turn clockwise, slip it under, and out they come!
 
It's alive again. And miraculously after the mandatory leaking, not tight enough, 90 adapter, no leaks yet. LOL.

Thanks for all the input, suggestions and levity folks. I do appreciate it!

Pat

 
Bet you have a smile on your face a mile wide.... I usually don't watch the videos clips but I did this one to share in your good results.

(BTW, what was all that smoke in the garage at the end? LOL :D)
