What in the world, is that tin baffel for, in the belt pulley housing, and how come it is held in place by a 90 deg. brass fitting? It looks like someone disconected a line and threw it away. can;t figgure why a line there, or where it might have went to. My IT manual doesn;t address it, but does show it without a line attatched. The Jensales manual does simular! I want to close it up with a new gasket, and don;t want to do that till I know more.

It has never been clear to me either; somehow the vent apparently allowed oil into the clutch housing which caused it to slip.
They apparently then came up with this tube to reroute the vent.
See if this info clears anything up.

Well according to your schematic, If there is no line going to the 90 fitting, then it must be supposed to be turned down, so oil can't enter. I had a lot of oil inside my bellhousing, because of the seal leaking around the jack shaft. I got it cleaned out and went to Bearings INC. and bought a seal that works well. the old seal didn't have a number on it, and my manuals didn't list a part number, so I took the old seal in and had it measured. They used a co2 fire extinguisher to quick freeze the rubber on the old seal, so it would not depress the rubber when using their calipers. I am going to post the replacement seal number here for anyone that might need to replace one. It is a CR12830, and fits snugly on the shaft, and is a press fit in the bellhousing recess.Acording to their measurements, it measures 1.281 ID and costs $6.49+ tax.

I wonder why they did't just put a pipe plug in the hole, and put a rain proof pressure relief hole in the hatch cover.

That is a splash guard to keep oil away from the elbow which acts as a breather. Don't plug this hole. The opening in the elbow should be down. As things warm up and the oil and air inside expand this breather allows air to escape and keeps oil from leaking past the seals. Every gearbox on those tractors is vented. The transmission and rearend vents through the gear shift tower. The rubber boot covers a groove on the front of the casting. Both final drives have small vent holes below the input shafts that vents into the cast tube.

If you tie up the rear lift arms, the cylinders stay full of oil. If you then fill up the hydraulic reservoir, be very careful if you lower the arms later. There is a vent for the hydraulic reservoir under the inspection plate under the starter (one of the little traps that AC engineering created.) (usually a brass elbow installed in a threaded hole) This vent will squirt any over filled oil directly onto the foot clutch!!! On my tractors, I have plugged this vent with a pipe plug. Then I drilled a hole and welded a pipe coupler in the inspection plate under the starter, at an angle, to miss the starter and installed a cylinder vent. The result is a dry clutch as oil fumes and any overfill are vented to the outside.
