Ok, I just bought this '56 wagon and have been tinkering with it. I noticed that one of the previous owners had installed an electric fuel pump back by the tank. I wanted to put a mechanical pump back on and found that the fuel pump push rod is stuck in the bore. I've tried vice-grips but can't get a good grip on it since it's a hardened rod. If I pull the intake off, would there be any way to drive the shaft out from above? I can't recall if it's accessible from above. Any other suggestions????

It would be necessary to remove the cam shaft to get at the other end.If I recall correctly some mechanics would install a longer front motor mount bolt to hold the rod up while installing a fuel pump.Try loosening the motor mount bolt that in line with the push rod.Someone may have install one that is too long.(the bolt hole intersects with the push rod hole-on all engines????....worth a try

The fuel pump rod can be bent and stuck in the bore. Take out the bolts as mentioned. I would pull my inner fender so you can get a straight shot at it. You could grind two flat spots on it with a Dremel motor, and then grip it with vise grips.
Or grind and then weld something to it for pulling it out.
I have done it before, but it just takes time.

If It has been on a elect. pump It could be carbon up. When you pull the bolt squirt some WD-40 In the hole and blow air in the hole If you have a compressor. Then try to tap It back up on the low side of the cam lobe, then turn the motor over to push It back down. Keep working It.

If you can get Vise-Grips on it could you get a 3/8 inch drill on it then spin it with the drill to get it unstuck?

Hi jay,

As the others mentioned, I would suspect the engine mount bolt is too long.

I sure hope that pushrod didn't wear the eccentric on the cam - since it can't move.

Remove the steel plate behind the fuel pump. If you can't get a vice grip on the rod - then I would weld a rod onto it - and give it a good yank.

Hey, if and when you get it out - tell us if its "hollow" or "solid"?

I agree with those who suggest loosening the engine mount bolts (no need to remove entirely just to free the push-rod, but you must replace with shorter ones when re-assembling for use) for a start.

But, what you really want to accomplish after this is to simply get the push-rod to move. I'd grind two flats on the end as already suggested, but grind them such that you can put a wrench on the end and try ROTATING the push-rod. An yes, I agree that spraying with a good penetrating oil would be wise also. Once you initially break it loose, the remainder of the removal job will be much easier.

Okay, the engine mount bolt is not holding in the push rod. It looks like they are the original short bolts. If I pull the timing chain cover off and pull out the cam, maybe I can force it out from the top. I can't even rotate the damn thing! I already pulled the intake off and am going to pull off the timing chain cover and pull out the cam tonight. If nothing else, I can at least see what kind of condition the valve train and the fuel pump push rod cam lobe is in. If it looks bad, then there's no sense even trying to get that rod out. And even if I could get the rod out from below, I'd never now what the cam lobe condition was, so I think the smart thing to do is pull the cam out. I'm in no hurry, so I might as well do it right.

hey jayspot
its a good idea to check that cam lobe,but can you tell if its stuck at its lowest point in the block,like when the pump is out it will normaly slide down.if so the cam may be ok,but if it is stuck further up in the block it just may have damaged the lobe plus you may not be able to get the cam out because the other lobes may not slide by the rod,if so you will still have to remove it from the bottom using the methods the others have stated.
good luck

I got my rod out of the hole!! ........ fuel pump rod, that is

I ended up welding a small chain to the end of the push rod, which gave me something to pry on. The rod is slightly bent which causes it to get stuck. Thanks for all the helpful advice!
