OLD SIZE/NEW SIZE
It has been years since tire manufacturers changed the numbering system on rear tractor tires. For those who have the older tires on your antique tractors, the change to the new system can be confusing.
When rubber tires were first used on tractors (1932-1938), the widest rear rim produced was 8”. With larger tires, the sidewalls were pulled in, causing the tire to be very rounded.
The first tire sizes (I) were the approximate tread width measured to the closest one-fourth inch.
In 1938, wider rims were used for better tire performance. With wider rims the tire beads were not pulled in as far, which allowed the tread to flatten and with a deeper tread the tires became more efficient. With the wider rim the same size tire has a wider tread width.
The second sizes (II) still used the approximate tread width. This method measured to the closest inch with no decimal points.
In the mid-50’s, the third number (III) method began. The new numbers referred to the overall width of the tire (sidewall to sidewall). This method measured to the closest tenth of an inch. The tires basically still had the same overall diameter and width as method (II), but a new number size. /

Cooling System

Cavitation Analysis- I blew an engine and Ford made good on it during the warranty period!

Source:

A very frequent question I receive via e-mail and on the Chat Board is about cavitation in the Ford diesels. It's a well-known problem, but doesn't seem to be as common as some people think. I myself have never personally seen one with the problem. Cavitation is not an inherent problem with Ford diesels, almost all diesel engines are subject to it without proper maintenance. The problem with Ford is that they originally neglected to put cavitation maintenance procedures in their owner's manuals. They have since remedied this with 94+ Power Strokes Owner's Manuals.

What is cavitation? One of our diesel experts offered this explanation:

Cavitation is a localized low pressure zone that forms adjacent to the outer wall of the cylinder. It is caused by by the flexing of the cylinder wall due to the high cylinder pressures experienced in diesel engine ignition. Gasoline engines don't typically get this failure mode due to lower cylinder pressures during ignition. Basically what happens is the cylinder wall quickly expands due to ignition then returns to its original geometry. This expansion of the cylinder wall is more pronounced as you increase the demand for power. Bascially when you increase your demand for power you are pumping more fuel into the cylinder. If you have a turbo charged unit you are also increasing air charge. This increase in fuel and air causes a more violent ignition which further increases cylinder pressures and thus increases the flexing of the cylinder wall. This fast cylinder wall movement causes a low pressure zone to be created in the coolant adjacent to the cylinder wall. When this pressure zone drops below the vapor pressure point (temperature, coolant ratio, and additive dependant) a vapor bubble is formed. When this low pressure zone returns to a high pressure zone, the vapor bubble collapses, causing an implosion, or pitting phenomena on the cylinder wall (like hitting the surface with a microscopic ball peen hammer). If left unchecked, it will eventually eat all the way through the cylinder wall.

The next question is probably What do I do to prevent cavitation? The answer is simple, add the appropriate coolant additive at 15,000 mile intervals and perform a complete coolant change every 30,000. By following these procedures, you'll never have a coolant-related failure. The additives include Ford's FW-16 (replacement for the older FW-15), Fleetguard's DCA4, Penray'sPencool, and others. A new alternative is to use Cat and Fleetguard's new extended life coolant. It is impregnated with the proper additive and mixed to the proper antifreeze/water combination at the factory. You simply pour it in.

ELECTRICAL

Troubleshooting:

Gauges don't work: Check the 7.5 amp in line fuse behind back of operator cab toolbox - This fuse holder is not visible but you can feel it with your hand if you reach through the back of the toolbox up onto the top of the torque converter.

Charging Problem: First place to look is the wire from the ignition switch to the voltage regulator. This is the only wire that is not direct between the alternator and voltage regulator. This setup is basically a one wire alternator like a GM. Three wires connect the voltage regulator to the alternator. The fourth wire goes to the back of the ignition switch. Check continuity on all four wires. Then replace your voltage regulator and finally your alternator (don't bother having it rebuilt it is cheaper to buy new on ebay - less than $100 incl. shipping).

Fuel System

If you live in cold climate where freezing is common, keep an eye on the fuel sending unit located under the cover above the fuel tank. It has supply and return fuel connections as well as electric. Remove three bolts that hold the cover in place and inspect around the sending unit for fuel leaks due to ice working in and around the hoses. A fuel leak will cause problems here. You could fill this area with open cell expanding foam to prevent problems.

This can also cause fuel starvation as the machine is running - symptoms might include engine runs well for awhile then begins to starve for fuel and die out, even completely - so before you go crazy on the fuel injectors or injection pump make sure there are no fuel or air leaks in the lines. See next paragraph.

I also had a problem with the machine starving for fuel intermittently while I was using it. It would just bog down, then, pick back up again and be normal after letting it idle. Usually the problem did not show up until the machine had been running awhile. I can not say for sure, but I fixed my fuel supply and return leaks at the sending unit and the problem has not returned. It seems to me that one way to check this is to fill the tank all the way to the fuel tank cap - 100% full - then let it sit - in a few days look at the area around the sending unit for leaks.

Power Steering Troubleshooting:

I found that poor or weak steering can be caused by old or contaminated fluid. Try draining the fluid , even use a siphon, put in new multi purpose lube as discussed above, and try that. Use of automotive power steering fluid will result in especially bad steering.

BRAKES

Brakes are adjusted through the linkage as it enters the rear differential case.

Tip: I ran my machine for 20+ years and never replaced the internal brake disks, but at one point I thought I would have to. What I found was a linkage problem instead. The linkage had become ceased and I was not getting full travel on the threaded rod going into the rear end. I disconnected the linkage below the cab and tried the pedals. They were ceased up behind the cowl in the operators cab just behind the brake pedal. I had to cut the pins at a shackle joint, carefully, so that I did not ruin the shackle. Then using jacks and other devices along with lots of PB blaster, worked the linkage until I got good movement. Problem solved.

STARTER

Cold Weather Starting

Cold Weather Starting

Cold Weather Starting: 1. Move fuel ON-Off lever full forward to ON. 2. Move the manual throttle lever to maximum speed, go outside the machine and push in the excess fuel button (on side of fuel injection pump) in the pivot shaft for the fuel shut off lever. You should hear a click as the rack springs back past its normal max fuel delivery position. If you push the excess fuel button in and it does not "click" and stay in, that is a good indication that the rack is stuck in the "off" position. 3. Crank engine and IMMEDIATELY move manual throttle back to minimum speed. Failure to move throttle back can damage the turbo and other components due to lack of good oil flow. 4. If after three or four cranks you do not have good smoke from exhaust pipe then a few squirts of starting fluid into the breather could help. No smoke = it will not start

Bleeding fuel system after you replace the fuel filter:

First bleed the fuel filter. I would fill the filter with fuel before putting it on, but either way open the bleed nut on top of the filter and pump the fuel hand pump until you get fuel out the bleeder. Close the bleeder. Then remove two fuel lines at the injectors. Crank engine until you get fuel out these lines. Tighten, engine should now start.
