ford 640

Hello, recently my hydraulic lift was slow to respond, I finally got it to lift and encountered a loud knocking and rattling in the pump area. I pulled the pump and found play on the gear and wobble shaft. Replaced the gear, bolted the pump back on and encountered the same knocking noise under...

When I try to start i t distributor spins and knock the cap off . I am trying to time it so I do not have it tightened all the way.

I have been working on this for a few days, I loosened the fan belt, connected a booster battery between the armature and field terminal and the generator turns, so the generator is OK. I just put in a new voltage regulator and still not charging?? I disconnected the field wire from the new...

1957 Ford 640 Fuel line replacement - has a NAA tank I've got a 57 ford 640 that I have been trying to bring back to life through the summer. I'm finally taking care of the fuel system and I'm replacing the fuel line. The one that was in place looks like old brake line mixed with 5/16 fuel line...

I'm working on renewing the bushings/bearings on the front of my 1955 Ford 640 but I have a question before I put it all back together. I've ordered a new bushing from Steiner tractor (ABC379) and had to order a threaded pivot pin (NCA3127A) from a different vendor as Steiner doesn't have the...

Hi all, been snooping for a long time but this is my first post. Tried searching and haven't been able to come up with an answer so hopefully I didn't overlook something simple. I have a 1955 Ford 640 with a square vane style hydraulic pump and a cast manifold. I've been researching switching...

Greetings all. I've been tinkering around with this Ford 600 series most of the winter. When I bought it, the hydraulic front loader worked pretty well. but then sporadically, it would not raise at times and then all of the sudden work just fine. I completely drained and replace the fluid...

I have a Ford 640 tractor. It is about 18F out side the 3pt. hitch will not work. The tractor is keep in a unheated barn, i had the space heater (110,000 BTU) blowing on it for about 45 min form about 3 to 4 feet and it still did not come up. What could be wrong with it ?

Been having problems with the battery going down on my 640 that I bought about a month ago. Previous owner done a 12 volt conversion. When I started tracking single wire from alternator back, I found that it wasn't attached to anything just loose. I have pulled up different wiring diagrams and...

New to the forums. Search didn't give up an answer. Crank pulley rim separated from the hub portion the other day. I figured 1955 to 2014 it has had a good life. I have a new pulley to put on but am stumped as to how to remove the old hub part and install the new one. Straight forward, 4...

Last year I had to do some work on my tractor with it not starting and ultimately traced it down to the starter. However, I wanted to clean everything up in there as there were jumper wires going nowhere, wire nuts, etc from the previous owner. So, I am finally getting time to work on it...

First off, this is my first post and I want to say thank you for everyone being as helpful as they are. I would have needed to post a long time ago if it wasnt for the knowledge base that has made this site so great....... I went to go fire my 640 the other day(the coldest morning we have had...

I'm trying to mount a drawbar on the underside of my Ford 640. It seems like a pretty straightforward operation, but there is some kind of flange around the PTO shaft that is in the way. Has anyone else run into this? Not sure what the flange does but it looks factory, and is heavily bolted on...

I bought this tractor well after the 12 Volt conversion was done to it. I was told the charging system worked but the Volt Meter wouldn't so I wasn't too concerned. I knew the 12V sealed beam lights didn't work but I figured that would be a fairly easy fix. Now that I have the hood off to fix a...

I ended up as the caretaker for a community owned tractor. She ran pretty good in the 800- 1700 RPM range but wouldn稚 idle lower and was balky at higher RPM痴. Today I put a timing light to her and confirmed the mechanical advance simply doesn稚. A look inside the distributor revealed 50+ years...

For a ford 640 what kind and how much do i need for transmission fluid, and for the Differential. Forgive my ignorance I'm a tractor owner as of 5 months ago, I probably didnt' even ask the question correctly. BUT>>>if you know what the heck I am taking about, some guidance would be...

I all, hope this is in the right place. I have a 640 ford and it is always worked hard and running great. It is time for a clean sweep on ignition, everything is due for replacement. The tractor is 12 volt by the way. I was reading and thinking about going all msd ignition. Has anyone done...

Hello All, Wondering how much oil should go in the differential of my 1955 Ford Model 640. My owners manual (fairly new reprint) and factory manual say 8.5 quarts; however, I drained more than 12 quarts a little while ago. Putting 8.5 back in does not raise the level to the plug on the side...

Ford 640 oil & Hydraulic Leak I have a new to me 1954 Ford 640. I am in the process of getting some years of abuse corrected. One of the problems I am having is 2 different leaks. The first, was a watered down hydraulic leak coming from near the inspection plate (?) by the hydraulic pump. I have...

Ford 640 3 Point Problem Hello, I just picked up a 1954 Ford 640 that has sat for a few years. Luckily, I got it for a great price and with an included 711 loader with brackets (not hooked up). However, the 3 point is dead. The previous owner said that the hydraulics stopped working a year or 2...

:confused2:I have 1957 Ford 640. The pto works fine until I hit a small sapling. The pto then kicks out. I opened the side cover and all berrings look and feel tight. The engagement arm looks fine. But Bushhog vibrates bad. can this make pto kick out. Thanks Steven

I would appreciate opinions on the value of a 1954 Ford 640. It isn't very nice to look at, paint spotted with rust, but not deep pitting or holes, a few dings and dents as well. It seems to run well and sounds good to my inexperianced ears. I drove it breifly and it seemed to have plenty of...

I have a situation of motor oil blowing out around oil filter adapter plate. No visable damage to adaptor or adaptor gasket. I have pulled oil pump and checked and cleaned pressure release. This old tractor had been flooded in local river and sat for several days.(Of course, no one mentioned...

Hydraulic fluid is gray and seems like range will vary sometimes, will raise 5' brush hog slow one time and fast another. Lever under seat seems like has 3 positions, up center or level and down. Would like to know what all 3 positions of lever are for, currently lever is wired in up...

Starting to rebuild this oldie but goodie of a tractor. Tractor runs, like to change to 12v

Didn't someone post a link on here to a guy who made power steering kits for Ford tractors? I can't find the link and am curious about the kits for a Ford 640. Thanks.

Picked up a \'57 Ford 640 Brought home my Dad's 640 over the weekend. She's a little ugly but mostly straight. Fenders are about the worst sheet metal spot. Bent in toward the seat and a few rust holes around the bolt heads. Runs out real fine. Needs some rewiring. Anyone have a wire diagram...

What's involved and what's the approximate cost to switch a 1956 Ford 640 to 12 volts???

Finally got some photos up in my gallery of my 1955 Ford 640. Here's a link. Slydogs Gallery
