New member IH 300 stuck motor?

[Dr. EVIL]

IH normally used STELLITE exhaust valves, VERY expensive alloy compared to the high grade steel of their intake valves. That's why the high cost. Hardened valve seat inserts in most of their tractor engines too, plus forged crankshafts, rods, etc. They were designed to run hour after hour at full load.

Well that makes sense, but that begs the question, if I find exhaust valves that are cheaper, does that mean they are not alloy?? Reason I ask, is because after seeing an average price of $30 per valve for the exhaust, I crossed the IH number to a Federal Mogul part, V1229x, and found them on line for $22 each.

Just read what Stellite is. Guy who invented it was named Elwood Haynes, and graduated from the Worcester Polytechnic Institute, coll thing is, I drove by there today, and my older brother graduated from there..........small world.

Well the head is off at the machine shop, awaiting it's turn in the jet cleaner, and bake oven. I oredered new intake valves, all new springs, and new guides. Decided to pull the pistons to better inspect them, and ran into a few snags.

First, I have been assuming thus tractor is a 300 utility, and thought it had a C169 motor. turns out it is a C175 motor. It is stamped right onto the block. So then I questioned if it might not be a 350 utility, then I found info that suggests they may have used C175 in the 300 near the end of the run. I had already ordered the valves, guides, and springs before realixing my error. Was mad at first, but then found the C169 and 175 share the same head

Problem now is to figure out exactly what piston/cylinder this motor uses. I found on the IH site they list only one number for the C175, but when crossing to a Clevite/Mahle number, they list 2 differant ones based on serial #.

The tops of the pistons I have are the "firecrater" style, but I think the differance might be in the wrist pin diameter.

Went to pull the oil pan, and get this, it won't clear the large support arm that comes from the front axle towards the rear.

Do I actually have to remove the front axle assembly to get the oil pan off

Here is another weird thing. What I can see for serial numbers does not coincide with what the online parts manual says I should be seeing.

The manual states all 300u engine serial numbers start with 9501 with a c169 prefix, and 350u engine numbers start with a 501, and a c175 prefix. My engine serial number appears to be 3615?2, the ? looks like either a 5 or a 6. This number is stamped into the block in a flat area just above where it is embossed C-175. Also below where the firing order is embossed, there are numbers seperated by little screw heads *3*17*0*.

The tractor serial # on a tag on the clutch housing is also not making much sense to me.
The parts manual says the chassis serial numbers for both the 300 and 350 should start with 501, but mine appears to be 18267, then a long space followed by a letter R. The suffix codes in the manual say the R would designate a tractor with Torque amplifier attachment, and if mine has a TA, great, but why is it missing the lever?

I'll post part 5 of the video soon.

Greetings from the USA.

Here is an update on the tractor:

Turns out it is not a 300, it is a 1958 model 350, and one of the last 350's ever made!

Bad news, I got the oil pan off, removed the #2 rod cap, and there is scoring on the bearing, and crank journal. I've gone as far as I want to in this guys yard, time to bring it home so I can pull the block and do a complete motor rebuild.

The torque amplifier is still a mystery. Tractor serial number has an R suffix indicating it was built with one, but parts of the linkage are missing. When I split the tractor, I'll learn if there is anything in the housing.

Does this motor have a full flow oil filter?
If not then add one.
Get a bracket like this

Older engines sometimes just had a bypass filter. That is ok, but not alone, imo.

In case anybody is subscribed to this thread, just wanted to let you know I am starting a new thread, since the stuck motor is no longer an issue, and since it is actually a model 350. So i'll be posting links to future videos on the new thread, titled " Utility 350 project"

Thanks to all who replied to this thread with input/advice,
