Hello all, I"ve had other tractors before, but this is my first fergy, I"ve owned a 8N a Case VAC a Long 445, and a Farmall H I"ve always done my own work, but I have found the best way to learn about a tractor is to talk to people who own the same tractor. I picked up my TO20 Sat. runs real good but after, putting a new oil pressure guage on it I find out it has no oil pressure. I ordered a rebuild kit for the oil pump last night, since I was off work today I decided to go ahead and take her oil pan off, and see what was going on. Bear with me I don"t have a manual yet so part of this may sound dumb. 1st thing I find is what I think is the strainer, bucket shaped deal with 2 holes in it, appears to me to be in wrong. Shouldn"t the open end be pointing down, so you could get a oil filter in there? 2nd thing it has no oil filter, shouldn"t the filter go in the open end of the strainer? 3rd thing the oil line coming from the pump to the pick up tube was loose, could this cause the no oil press. problem? The pump is off and seems to work, when turned by hand seems like it should have worked, but it is off now and the kit is on the way so I"m going to rebuild it anyway. Anybody has any suggestions on the best way to go about rebuilding the pump? I took the #4 rod cap off the check the bearings, they looked good, but I went ahead and ordered a new set form my local dealer this evening, thought since I was ther I might as well change them to. Any suggestions as to what else to look at while the pan is off. Thanks for taking the time to read this, the search an this site has been a great help, but some of this stuff I couldn"t find. Thanks again jeff

Jeff, sounds like you know more about the Z120 Continental engine than you thought. Right on all accounts, loose strainer means your pump is sucking air instead of oil, stainer does go on open end down so you can access filter thru the plate on the bottom of your oil pan... yes you are suppose to have a filter on there. You may not need a pump rebuild at all.
Note on the filters, check Ebay, I got a good deal on a set of 4 oil filters a while back. I won't have to buy any more oil filters for several years and the price was great!

I rebuilt my oil pump several years back. What the other guys say is right, the rebuild kit has an aluminum gear, you have to drill 1/2 in the steel shaft and 1/2 in the aluminum and tap it for the setscrew. Pretty much impossible to do by hand. I was able to do it easily enough with a drill press though. Wait for your manual before doing the job. You will want to check your clearances, backlash etc. I didn't press in new bushings for the pump shaft, mine didn't seem to need it. My pressure relief valve was SHOT, and probably the main cause for my low pressure. Parts to rebuild the relief valve come in the pump rebuild kit. An easy job.

A loose pickup tube certainly could have been your problem if it was sucking air. On the Oil filter installation: There should be two pipes coming down, one off to the side which is the oil pump pickup, and one down center coming from the center crank bearing. This center tube delivers oil to the center of the filter through a tiny hole in the side of the tube. Don�t enlarge this hole or you could cause a drop in oil pressure! A spring should go on this tube first, then the �bucket� with the closed end with holes on top so the spring can push down on it, then the strainer (same direction as the bucket) then the filter in the bottom. Usually you do this with the oil pan installed and work through the large hand hole in the bottom of the pan. The previous owner had welded the bottom cover shut on my TO20 so it was tricky getting all that in place and then installing the pan!

Good luck with your new fergy.
Dan

Answer to your various queries, - yes. Pump overhaul - make sure gear is properly fitted to shaft. Usual problem is gear turning on shaft. Some kits supply an alloy gear & a grubscrew. You"re supposed to drill / tap half in gear / half in shaft to accept screw. Ever tried drilling half in soft alloy / half in steel? Drill bypasses steel into alloy. I didn"t even bother fitting alloy gear - used old steel one - much easier to drill/tap half in each.
