Transmission Fluid Fill and Brake Drum, Model A

Two last questions regarding my '49 Model A

I went to change the transmission fluid emptying both drain plugs and it looks like about 6-7 gallons came out. Checking the manual it looks like the tractor takes 8 gallons. I measured out and added 8 gallons to the fill hole (see picture) and as soon as I pulled the funnel, a lot of fluid poured back out. Am I filling it wrong? To check the proper level of the transmission oil, is it just level to the top of the fill hole in the picture I've attached (where the cap is off)?

Second, I can't for the life of me figure out how to get this brake drum off (see second picture). I read about three bolts somewhere and don't see any. Any thoughts on how to get it off?

Thanks for the help over the last couple days. I appreciate your time, these should be the last questions..at least for a while!

Fill oil to level of hole. How ever much it takes.
There are 3 bolts that hold the complete brake assy. to the main case. You have to remove the whole thing first. Then loosen the castle nut on the brake shaft and drop the assy. onto a wood block while holding it stable and the shaft will pop out.

The 3 bolts hold the entire brake assembly to the tractor. Once you remove the brake assembly there is a nut on the inner end of the drum shaft to remove. I wouldn't be to worried about the transmission oil, there are some areas that the oil needs to seep through a bearing to fill a cavity in the transmission, like under the 4/6 gear tin cover.

When you get the three bolts out, you will need to work something into the edge of the flange to start it out, then pry with a bar. There is an alignment dowel as well as the three bolts. They can be somewhat stubborn sometimes.
Now that I think about it, the bottom bolt is more than likely a stud into the case with a nut on it.

Your tractor probably has a few quarts of sludge in the bottom of the transmission from the past 60 plus years. I'd just fill it to the top of the plug threads and call it good.

Take a look at the table below.



Note that [b:654c4848f0]OPERATOR'S MANUAL No. OM-R2001R[/b:654c4848f0] "[i:654c4848f0]contains correct information about the lubrication, operation, and preventative maintenance of your John Deere Tractor[/i:654c4848f0]" for serial numbers 584000 to 647999.

Reviewed the above operator's manual under the [b:654c4848f0]TRANSMISSION LUBRICATION[/b:654c4848f0] topic on page 23 and it lists 7 gallons as the oil capacity.

Take a look at the [b:654c4848f0]BRAKES[/b:654c4848f0] diagram below.





Note the cap screw(Key 19), stud (L.H. Side only)(Key 23), and housing (Key 24).

Take a look at the photo below of the left side of "Old John" Nancy's 48A.





Take a look at the end of the brake shaft with 1" nut.



Remove the cotter pin (Key 35), 1" nut (Key 34), washer (Key 33), and pinion (Key 35).





Loosen the adjusting screw (Key 15) by turning it clockwise to remove tension on the springs.







Remove the brake drum (Key 1) and brake shaft (Key 2).



Hope this helps.

Thanks very much for the great advise and pictures, I'm good to go now.
