The threads are 1/8 inch pipe threads, the early TD6 did not have a lube fitting there, the later TD6's do, the parts catalog shows after serial number TBK 31068 (1952 model) they had the zerk fitting, yours is an earlier tractor, a previous owner many have upgraded to the newer steering clutch release fork at some time. That happens a lot when the tractor has been through different owners, lots of parts get changed with no record. Item 1 is your zerk fitting.

Yes there is a difference, 1956 TD6 would be a 61 series, 1959 the 62 series came out, 62 series used a D282 direct start (glow plugs) 6 cylinder engine, the 61 series used the D264 or D281 4 cylinder gas start diesel engine. The earlier TD6 tractors used the D248 gas start diesel engine. The later (62 series) have 1000 hour rollers, top idler, gear shift lever is located on the right side of the compartment. There are other small changes, mostly cosmetic. Some parts are interchangeable.

Where is this plate located? It looks to be the tractor serial number plate; it should be located on the dash in front of the right brake pedal. Can you take a better picture of this plate and its location.

Serial number plate should be located above the right brake pedal on the early TD6's.

Thats an early TD6, not a TD6-61 (1956-1959) or TD6-62 series, (late 1958, '59 model to 1969.

Power washer with the drain plug out, then lube all the fittings and work the tractor to get it hot in there. Is this a bare tractor, loader, bulldozer?

Yes, between the two-brake inspection covers, you may need to slide the drawbar to one side to see it as mmi stated. There is a lot of oil (16 quarts) in the transmission as it is common with the ring and pinion section. Check ebay for a manual, try to get an original IH operators manual, the reproduction manuals sometime are missing pages and also can be hard to read as they are reprints. My question about being a 61 or 62 series is you call it out as a 1956, 62 series began with the '58 models, do you have a serial number for the tractor? The 61 and 62 series use a lot of the same common parts. Post some pictures of your tractor.

Get yourself an operator's manual, I've attached a couple of pages from the operator's manual, be sure and lube the clutch zerk fittings, the pilot bearing too, also the brake pedal zerk fittings that are in the clutch compartment, use a flashlight to find them. The final drives and transmission use 90 weight gear oil. Is this a 61 or 62 series?

Nice straight looking TD6-62 series, they first came out late 1958, what is the serial number of your tractor, the plate riveted on the lower left of the dash has the model and serial number.

Yes they are interchangeable, The D236, D282 and D301 use the same head, the early heads have smaller valves, IN 1.647-1.657, EX 1.295-1.305 for the early heads, IN 1.674-1.684, EX 1.370-1.380 for the late heads. Be sure you have the heads checked for cracks, they are notorious for cracking the heads, the cracks are repairable, leave the engine idle for a minimum of 3 minutes at shutdown.

edca, Put a breather vent in place of that hose, it will keep dirt out of the transmission, also check to see if there is a breather on the torque converter, the C series has them, IH or Dresser may have done away with the torque converter breather with the later series, the breather for the torque converter is located on the right side behind the engine in front of the dash, you can see it below the air filter. These tractors have a torque converter (fluid coupling), they need full rpm to transmit the power to the transmission.

edca, can you take a picture of the hose in question, is the hose in question on the transmission or the torque converter? These power shift tractors need to have the transmission oil warm to work properly, they also need full throttle when operating.

gxr2001 Yes you can put the zerk in as is, it is tight but it is the only way as you need to remove the zerk to pull the clutch, the engine clutch shaft will not move far enough back with the zerk fitting in place to remove the clutch. Be sure you use a zerk fitting that is extended with a 45 degree angle nipple.

GXR2000, Get a zerk fitting into the end of your engine clutch shaft(13) the pilot bearing is a ball bearing it needs grease, it takes a lot of grease to reach the pilot bearing if the shaft is dry, it took over thirty pumps on the grease gun to reach the pilot bearing on a new shaft install. It looks like you are missing the engine clutch brake disc(9) it should be riveted to the engine clutch coupling (10). Adjust the clutch so that it takes 40 lbs of pull on the clutch lever. That looks like a 62 series TD6.

Dave, good tractors, they are a construction tractor with full power shift, 3 forward, 3 reverse. You can put a winch on it, IH never offered a PTO or three point hitch for the TD7C or TD7E, you could build your own three point, it would not have draft control. What are you intending to use the tractor for? With that serial number it is a very late model, 1989 was the last year they were produced.

Does it look like either one of these blades, these are the ag blades for the T340 series crawlers, the TD5 may be similar.

Try Quality Diesel Parts, Portland OR, 1-800-877-2810, they show the part listed for $98.00, it may be a dead end. You can have that clamp made if you can't find one.

I am not on the Heavy Equipment Forums site; do you need more info than what's on the brochures? I do not have a TD-7C, I have a 100C which uses the same platform as the TD-7C, I can post more info from my owner's manual or from the service manual if you need it. Hy-Tran oil or equivalent is used in the power shift transmission and the rear main frame. I have been using NAPA 85-405 in my 100C for over 30 years with no issues.

Here you go, T-7C, TD-7C. I don't know if IH produced any gas T-7C's, they would be very rare.

Nice straight looking crawlers, save them.

HydroTek is correct, they are not shown in the parts book.

WIX 33148 NAPA 3148

Bought new in '69, that picture is January '84 after we put undercarriage, clutches, brakes and paint, turbo was put on in '72, in-frame and undercarriage going on right now, still is a daily worker for us.

TD6 5 roller (extended track frame option) have two top idlers.

They rust, I have also seen a lot of sprocket shields damaged, the owners take them off instead of replacing or repairing.
