    8n parts catalog page 189 - bolt part numbers

    Thank you very much for your help about the 's'. I just found the info and turns out to be the finish of the bolt. I have used the catalog a lot but I have overlooked that page and now I feel just a little bit dumb. As for the 8n9807, the one on my tractor is not straight but is bent at a...

    8n parts catalog page 189 - bolt part numbers

    I have a question about the part numbers found on page 189 of the 8n parts catalog. When I look at the part on page 50, the bolt that connects the lever to the rod is identified as 20405-s. When I look at the bolts on page 189, I find bolt 20405-s8. There are other pn's with only the s at the...

    rear tires

    thank you for all of your comments so far. However, I still do not know what to do about the tires seeming to be low on air but the tire pressure is above 12 psi. is this a matter of old tires and the fluid inside the tires or tires just being old. I have trouble keeping my own pressure up to...

    rear tires

    i am sure that the tires are tubeless. the date that the automobile tires are made is encoded in the dot code. for example, i just bought a set of tires for my toyota. on the side of the tire is this code:1PLOF3C1R1523, the 1523 is the date that tire was made. the 15 is the week of the year...

    rear tires

    I have a 1951 8n. I know that the manuals say set tire pressure at about 12 psi if no load or maybe bush hog. My tractor was showing a lot of 'squat', ie, it looked low on air. to fix the squat, i put in air until the tire was looking more full. the right tire showed over 20 psi and the left...

    measure rpms on 1951 ford 8n tractor

    First of all, I would like to thank all of you that helped me with your responses. Here is the current status: I brought a non-contact tachometer and placed reflective tape on three different places. One on the PTO shaft, one on the crank shaft pulley and one on the alternator. I cranked up the...

    measure rpms on 1951 ford 8n tractor

    How would I get to a place to get the rpms on the crank shaft pulley? The belt on the alternator is adjusted to the half inch stack and seems to be OK. I made a mistake about the PTO calculation. If the the PTO rpms is 600 (for example), the engine rpm would be 600 times 2.75 = 1650. I had...

    measure rpms on 1951 ford 8n tractor

    I have a 1951 ford 8n and I want to know if I can measure rpms with non-contact tach. I want to get an accurate reading of the current rpms so I can tell if the other stuff is accurate. I need a baseline. I want the rpms not depending on proofmeters that may be wrong or carb adjustments, etc...

    8N wiring

    In my ammeter research I did not find an explanation for 30-0-30 in the description. Please let me know what this means.

    8N wiring

    I did a little more research on ammeters. Some ammeters have a + and a - post that is marked. Others have a +L and a +B. Wikilink says that this is non-standard but a lot of manufacturer use it. The +L and +B is totaly confusing since the +L connects to the battery and the +B connects to the...

    8N wiring

    First of all I would like to thank you all for the responses to my question about moving the connections for the ignition switch. I may try the change later. I did not mean to start a big argument about the wiring. I did not properly describe what I had. I used the wiring diagram...

    8N wiring

    I was trying to give a reference to the wiring that I used. Here is a description of part of the wiring: one wire from alternator to negative post on ammeter. There are two wires on the positive post of the ammeter. One to the solenoid and one to ignition switch. The ignition switch's other wire...

    8N wiring

    I have 1951 8N tractor that has been converted to 12 volts. Can the Ignition switch be wired between the wire from the solenoid and the ammeter gauge. Since the ignition switch is really an on/off switch, that seems to be a way to cut the power in case of an electrical problem. This also seems...
