    5040 Loader inoperative

    We had part of this discussion a while back about the interaction of the 3-point and the auxiliary remotes. You can have either one but not both at the same time. I found that the 3 point lever was frozen in place, how its frozen, I'm not sure but the selection lever does operate and when 3...

    5040 Loader inoperative

    I had used the loader (Allied 394) once before to move a little gravel-very little. I was working on other parts of the 5040 tractor and needed to fill a small mud puddle. The loader worked OK but very slow. Sometime later, I thought I had all repairs under control. I decided to move about two...

    5040 Remote Selection

    Is anybody still there? I'm still fighting the remote vs. 3-point problem. The number 10 lever easily moves to the horizontal position and disconnects the remotes. Thank you, but now, the number 1 lever for the uplift/down lift remains frozen in the mid position, as is the draft control lever in...

    5040 Remote Selection

    No such luck. The loader is totally dependent on the engine driven pump through the remotes, not an A-C loader. The PTO is free for other jobs. Thanks for the thought.

    5040 Remote Selection

    Thanks Harry, Suspicions confirmed. Over the years I have reclaimed Farmall letter series and Ford N and 100 series to keep busy, this 5040 is quite a step up. The whole idea was to help a neighbor level up a pasture so the loader/box blade interaction will be interesting. I'm not sure where I'm...

    5040 Remote Selection

    I have a dumb question, the remote selector valve in the photo (# 10) seems to select between normal 3-point hydraulics and the remote hoses. At the moment the #10 lever is vertical, and the front-end loader works perfectly. The 3-point operation is nonfunctional. I am new to this tractor, and I...

    AC 5040 Safety Switch

    Thats great and yes, it is on top of transmission, and I found some great pictures of the part by you (gatz271) in a forum search published in 2019. I'll pull it out again and fool with it, but I'm sure it's beyond my pay grade to fix. I think my plan will be to go around it until I find me a...

    AC 5040 Safety Switch

    Thanks Jim, I have a parts book that shows a part number 2091942 as safety start switch with the boot included. I have surfed through the AGCO listings with both 2091942 and 70291924v and can't seem to connect. I also noticed that several 5040's I looked at had the safety switch disconnected so...

    AC 5040 Safety Switch

    I recently acquired a 5040 and found the safety switch inoperative. I have manuals and parts book, but I have found safety switches for a great many tractors. Not so for a 5040. Can anyone tell me if the switch is a problem with this model and where I might find one? I do lurk on the Ford...

    5040 oil and lube question

    Thank you all. 15W40 and TSC it is. As soon as I get it cleaned up. WE can start making it a neat old working tractor. By the way, it came from the cold country and is equipped with a heater. Thanks again guys.

    5040 oil and lube question

    I just acquired a really nice barn find, 5040 (diesel) and the book calls for Allis Chalmers 831 power fluid in hydraulics and SAE 30 in the oil. Does anyone see any problem with Tractor Supply universal hydraulic fluid and a 10W-40 oil synthetic or non-synthetic? I never fooled with this...

    550 hydraulic oil specs

    Thanks guys, I was pretty sure it was OK but needed a little hand holding. I think I got the 550 project that I always wanted, but it is really a full resurrecting job and there is a long road ahead.

    550 hydraulic oil specs

    Just started using my Oliver 550 between tear downs and discovered that my hydraulic oil is at the fill mark. I have all the manuals and the book calls for SAE 30 with Oliver 102 082 A additive. The fluid on the stick looks like new, clear light weight oil so would you just add oil, universal...

    Thanks for the response SW3. I suspected that it was OK but needed some backup and your help was just the ticket. Thanks again

    550 hydraulic pump

    After a year and a half, I have finally got my salvage 550 operational (sort of). I took it out to do some leveling on an irrigated pasture today and really go a shock at how hot the hydraulic pump exterior got. I could not hold my leg against the unit - not boiling hot but measured at shut down...

    550 Missing Gears

    As some of you may remember, I have been trying to resurrect a former Highway Department cast off Oliver 550 these past 18 months. Poor thing was scheduled for scrap. I never tried to redo an Oliver before, and this looked to be the ultimate test. I recently got it up and running after a...

    550, what's this thing?

    I cut the buzzer out of the equation on my 550 with a simple wire from ignition switch to light to oil sensor. No oil pressure the sensor is grounded and light works. Oil pressure pushes plunger and ground is lost and no light. I think I want to replace the light system with a real oil pressure...

    550 carburetor application

    WHOO. I found it..the Zenith 14644 was used on the Cockshutt and its application can be seen on Mike's Carb Parts which also indicates use on the 550. Also data on page 192 of Zenith's carb spec sheet. Near as I can tell from Mike's is that their repair kit K676 is not available. I wonder if the...
