300 center section.

[Ohio-H]

Should there be oil in a 300 center section?

 

[Janicholson]

At the clutch, no. Do a paper test with the Hytran and engine oil to see which it is! It is a split either way. If TA leak it could be a double split. Jim

The areas with the red lines around them should not have oil in them. The rectangular area more on the center of the photo is the 7” direct drive TA clutch cavity. There is two weep holes about a 1/2” in diameter on the bottom of that to drain away oil that has leaked by failed seals. That area has an odd shaped oval bumped out cover of the top of it, has 4 5/16” cap screws in it. A metal cover goes over all that area and reduces the size of the cover I am talking about.

Thanks for the picture and explanation. I have 3- 300's, a 330 and a 350, all utilities but none have a TA. Never had one or seen one opened up....James

Are the center sections shorter on a utility? Are the utilitys shorter without a TA, or the same length. I know a 300 Farmall center sections looks longer than an H but there were no 00 series Farmalls around here. There just wasn't much field farming going on in the 40's, 50's and 60's. Livestock and orchards, a little grain farming, mostly for farm use. Very poor farming area, lot of stump one horse homesteads. Timber was king. Dad milked 40 cows and grew 20 acres of grain on old cleared orchard land. Worn out prune orchards were planted to subterranean clover for seed or pasture or put in soil bank and planted to vetch. Steep land was farmed with crawler tractors or utility tractors for haying. Just never see a TA or fast hitch tractor here. Very seldom ever saw a fast hitch implement here in the Willamette Valley. IHC W 12 was a favorite tractor, low and stable, Fords were dangerous....James

It is longer on the mta, hundred, and fifty series than the h and m. The hood amd gas tank are longer on an mta than an m to make up for it.
They just put a shaft in place of the TA when ordered without.

Utility and Farmall used the same size center and transmission housings. H and SH center housings had the same length as a 300 but won't work on each other,

Where is this video so a person could watch it?

Where is this video so a person could watch it?

I should have known this would come up. The video I found several years ago. It is a 16 second clip of two participants at a Red Power show operating the cut away TA display unit. The problem is the person cranking the engine input end turns it backwards so it does not provide a true representation of the action of the driven parts because the one way clutch never locks due to everything is being turned in the “free wheeling” direction. I added a blue arrow to the photo showing the location of the one way clutch. I have no idea what tractor the TA section is out of, I tried a web search of what I think the casting number is but it gave no results. The mechanical TA was used in many different sized tractors, I am not sure if the 300 was about the smallest tractor it was put in. It was used in models up the the 686. Through the range of different models many of the internal parts are the same part numbers, on our farm we had a 300, 350 and a 656 Farmall. For that reason I looked up the parts in the TAs of both the smaller and larger tractors. One of the main parts of the one way clutch that IH called the “ramp assembly” PN365402R11 is the same in both sizes of tractors. I have posted this before, the highest horsepower application that the mechanical TA was used in was the 660 at 95 engine hp, 70 hp at the drawbar.

Picture is a 300-type housing. Only difference between most T/A unit and clutch between a 300 ETC. and a 400 ETC. is at shaft and housing for unit that fits in transmission. Both the same back to and including ramp and roller assembly. 300 with t/A had a change part way through production that changed cover on top of center housing to use a 3-bolt cover instead of 4-bolt cover over the clutch plate and disc. Three bolt cover used in later series tractors. When second picture is added to rear of first picture a 300 or 400 is the same to that point. Other pictures is parts from a complete tear down and repair.
