I have a 1953 Jubilee with the 134 ci engine that I just completely rebuilt due to a broken valve going through one of the pistons. I had the block 'boiled', re-sleeved and decked. I have installed new pistons and rings. I had the head redone with new valve guides etc. I have replaced all the bearings and have mike'd the diameters and verified the correct bearings are in place. The crank was polished as well.

My problem is that I am getting no oil pressure reading and no oil to the top of the engine (rocker arms & head). I have checked the guage with air and it works fine through the sending tube. I have a new oil pump, a rubber gasket in the sending tube from the oil pump to the filter as well as at the base of the tube taking oil up to the head. I have verified that the pickup and sending tubes are not cracked in any way and have verified that the channels in the block are not blocked. Additionally, I believe that plenty of oil is getting to the cam and crank journals as they are dripping oil from one end to the other. It is about forty degrees out and I am using SAE 30 oil. I am at a loss as to what the problem is. Any ideas would be appreciated. Thanks.

Andy

I never worked on a 134 before and not sure if they are the same as a 172 in the later tractors but on the 172 the cam has to be turning to get oil to the head. There is a hole in the center cam bearing that has to line up with the oil passages and it takes quite awhile to get to the head the first time you fire it up. I just rebuilt may 63 4000 with the 172 and I dumped a good amount of oil an the valve train first and I used assembly lube too first. I'd have to agree though that it sounds like you might have a plug missing somewhere as to your other oil pressure problems. my 2cents worth Greg NE

Thanks for the quick replies. To answer Dan"s questions, I did use lots of STP in putting the motor back together. I had already spun the oil pump while in the motor with a screwdriver bit on the end of a drill and the pump is well primed as it pushes oil into the filter very well and into the crank and camshafts. I even took the pump out and spun it while in a bucket of oil just to make sure it was pumping. Technically, this is the second pump I have tried. It just does not have enough to push the oil up top for some reason. I know that it is installed correctly as I have pulled the distributer to make sure that the slot is turning with the distributor as well. Should I see oil coming out of the upper tube when turning with the drill or does the motor need to be running as well? I have not had the motor actually running for more than a few seconds at a time because of the concern with the oil pressure. Also, I have been manually adding oil to the head and valve train while working on it.

I learned about STP the hard way. About 35 years ago I rebuilt a 390 and coated everything with STP. Fired it up and 30 minutes later one lobe on a brand new camshaft was flat. I had put STP on each lobe and on each lifter and it failed. I now use nothing but engine assembly moly grease that comes in a plastic tube.

Good to hear you lubed everything up good when you re-assembled. Well then - did you put the oil galley plugs back in on both ends like fnhtech mentioned? They are very easy to forget - heck a few weeks ago I had to pull off my cam shaft gear back off to replace one I left out of my 8N rebuild.

Did you pull the oil intake tube off the top of the rocker shaft to see if oil comes out while spinning the oil pump? Until you get to fairly high RPMs, you don't really see a lot of oil coming out of the rocker shaft while running.

The other posters have you on the track with the things that are usually wrong. Here are some "head slappers".

Did you put the oil pump drive shaft in?

Are the splines on the drive shaft in good condition or worn? If it is bad it will slip and not spin the pump.

Did you use the correct oil pump? As I understand it, at one point the OP was changed and that requires different piping. Memory is fuzzy here.... could be all wrong.

Did you pack the OP gears with grease or oil them to help prime? Shouldn't be needed, but...

Dan has you on the right track. I just wanted to mention something that is occasionally overlooked...the main oil galley plugs at the front and rear of the block. Another easily overlooked item is the small plugs in the ends of the rocker arm shaft.

Once I also encountered a problem with the relief valve in a brand new oil pump. In that case the valve was stuck shut and allowed exteme oil pressure. If the valve would be stuck open it would result in low/no oil pressure.

Just a couple of thoughts off the top of my head.
Good luck!!

Andy - hope you put plenty of assembly oil/grease on the moving parts when you put it back together. DO NOT start it again until you get the oil pressure problem solved. You should be able to remove the oil pressure gauge line and see oil pushing through with just cranking power unless your battery is real weak. Or, simply remove the oil filter and watch it there.

You may need to spin the pump faster to get it to prime. The easiest way is to remove the distributor (after marking the rotor direction so you can return it to the right spot) and use a long flat bladed bit chucked up to a drill. This will spin the oil pump much faster than the starter will if that method fails. Make sure you are turning it clockwise. Unless your oil pump cover or cover gasket is warped and alowing air to suck in, this should do the trick.

If all else fails, you will need to pull the oil pan and pull the oil pump to discover what is going on. If it comes to that, fill the oil pump with assembly grease for an easy prime on startup.

Good luck,
Dan
