fuel pump push rod

[lil mac]

Been having trouble w/blowing diaphrams and gas going into oil pan. After removing the fuel pump to replace the diaphram I discovered I cannot remove the push rod. Normally I can pull it out w/no problem. It comes out about 1/4 to 1/2" and hits a wall like feeling. I turn it around same thing. Its not tight. Anybody ever had this problem?

Forgot to mention the tractor is a Farmall F-14

sounds like the rod is mushroomed on the end. need to get another rod.
check camshaft essentric also.

Mac,Youve got a problem ive never heard,If you remove the oil pan you should be able to get to it.I think that pushrod goes through a peice of the block to hold it in place.Might take a grinder to clean up the end or you might have to cut it off

I have a new rod and diaphram from Rice. I put a new rod in about 3-years ago and the old slipped rite out as did the new one. If it was bent it would slowly tighten up but I put vice grip on and it feels like it is hitting th wall all around. When I pull hard it still turns 360 easily.

thats because the end is mushroomed as i said. need to remove pan and check out the problem. as suggested need to grind the mushroom off to get it out. cam essentric is probably buggard too. i have seen this before.
