puel pump and distrib. not functioning

[terryb]

hello gentlemen, I experienced a problem with my '51cj3a today. I took it for a drive after doing some steering repairs, I got about 1/8 mile down the road and it quit on me. after cranking it over for a few sec. I noticed no fuel in the fuel pump sight glass. I assumed it was out so I dumped in 3 gals. and still no good. towed it home and after some investigating found the fuel pump not pumping and the distributor not turning. i have gone any further yet.  was wondering if anyone else ran into this problem. im hoping its just a sheared key on the cam. 
thank you for any and all possibilities

Both run off of the camshaft. It doesn't sound good.You can take off your valve cover and see if camshaft is turning. The oil pump and distributor are linked but the fuel pump has it's own lobe on the camshaft

Pull your dip stick and smell your oil. Pump diaphragm has possibly failed dumping fuel into your oil. Distributor runs directly off oil pump. Gasoline-diluted oil does not lubricate very well at all. Oil pump may have seized. Just got through with the fix for this. Another fuel pump and another oil pump. I replaced my distributor while I was at it.[/b]

thanks guys,  i'll check these out...

thanks for the replies, Steve and Scoutpilot. I was finely able to tear into the jeep today, I pulled the line off the fuel pump and it was pumping fuel. I pulled the distributor and it seems ok. I pulled the oil pump out and its missing 3 teeth on the gear.   not sure where to go from here.   any suggestions as why this happened. I cannot turn the pump gear and don't know why it would have locked up and sheared off the teeth. the fuel pump and distributor are new parts. the oil pump is the original pump. I guess I will have to pull the pan to retrieve the teeth. im hoping the teeth on the cam are ok.
thanks again for all replies

Can you post a picture of the oil pump? There has been issues with new ones locking up. I'm wondering if it is a new one or original.

[terryb]

sorry but im not good at posting pic. as far as I know this is the original pump. the pump has 2 gears inside that run side by side. after taking off the end cover, every thing is free but still wondering why this happened.

[scoutpilot]

It is an older pump and likely the original. Do you recall how much oil pressure was indicated at the time of failure? Did you smell your oil? How long was it between this last run and the previous run? Had the pump been off the motor at any time prior to this last run?

[terryb]

I didn't notice the oil pressure when this happened. I had just finished some steering part replacements and took it down the road. the pump has been on since the motor was rebuilt. oil is fairly fresh and at full mark. I have taken about 2 dozen short trips in my jeep since the rebuild.
thanks guys

Did you remove valve cover and see if camshaft is turning? If it is then hopefully the hardness of the camshaft won out over the oil pump and a new pump may be the solution to it although not sure about fuel pump going empty before and not now.

[terryb]

hi Steve, took your advice and removed the valve cover and the cam seems to be ok. the valves are working up and down.
my next step will be a new oil pump from Walcks. It will probably be a week or so before I get one and get it installed.   I do appreciate all the advice and answers I get on the forum. it makes it a lot easier for a guy like me to where I am with this old willys.

Before you place that order take a really good look with a flashlight at the gear teeth on the camshaft and make sure there isn't any damage you might have missed. Hopefully the cam is OK and just an oil pump will fix the problem.
When you do install the oil pump make sure there is adequate end clearance so it doesn't seize up and cause a similar issue. Also might be a good idea to pull the pickup tube and screen and make sure they are clean.

2 gears side by side sound like a new style one. The original would have had one gear inside the other. I'll post some pictures later on.

According to the manual the "old" style pump before engine #44417 had the pressure relief in the pump cover, and the "new" pump has it in the body of the pump. But my new-this-year pump has the relief valve in the cap/cover, but no drain plug/cover plug as in the old-old pumps..

Perfectly clear...

Why Willys, Why?
