I just read a post about the cotter key... didnt find it in the owners manual.. Where is it located and what should I check and is there any maintenance on it. I have a 1955 TO35
 
Should be two of them under the machine. You will only see the "ears" hanging down. They should freely rotate.
Those are the vibrating mechanical dirt scrubbers that keep the weep holes open and able to drain if needed.
 
The TO 35 has one according to my parts book number 693 063 M4 on page 160 and #7 in the description on page 161. It should go in the bottom of the bell housing. My TO 30 has two both located in the bell housing area 15 inches apart.
 
Richard,
Can a new cotter key be installed in the transmission case weep hole on a 1957 TO35 without taking the bell house loose from the motor block?

Say go through the inspection plate under the clutch area.

If not, could you drill a weep hole in the clutch inspection plate and insert a up side down cotter key in the plate. Would it be of any value to keep the transmission housing drained of seepage oil?

Thanks,
Fred
 
Maxwell good question. I had to go find an answer for you. If it can be done your way a person will have to have thinner hands and longer fingers than I have. After putting hand into hole there is a decent drop down so if you are able to keep the cotter pin in the very extreme tips of the fingers it is possible you may get the pin into the hole. I won't say it CAN NOT be done. Good luck. I would think if you checked that hole once a month to make sure it is open or more often if you have reason to believe it may have gotten plugged that would be a better idea than drilling another hole in it. The TO 20/30 does have two holes in the bell housing area however my TO 35 only has one hole.
 
Thanks,

I will just check the weep hole and be sure it's open from time to time, that sounds like my best bet for now.
