Brake Pedal Shaft, Clutch, & Steering

Postby WildFarmall » Mon Mar 18, 2019 3:08 pm

More questions from WildFarmall!
1. When I took the fill plugs out of my steering housing nothing came out. Looking further I see that someone before me put a bunch of grease in there instead of 90 wt. oil. Should I flush out the grease with kerosene and then fill with oil? My guess is that it was done to keep the front housing from leaking. I am not keen on doing that now as I am running out of energy and time. What do you all recommend?
2. I have the best picture of my clutch that I could take. I will put grease in the fitting but is there anything else I should do or not do?
3. The shaft that my brake pedal is on has a hole in it where it looks like a cotter pin should go and a washer so that the shaft does not slide in. There was not one there when I took it apart and it seemed to work fine without it. Should there be a washer and cotter pin?
THanks so much everyone!

1) You are probably correct that the previous owner substituted grease for oil to stop the oil leak. There should be a vent hole in fill plug. If the hole is plugged up, that could have caused the leak. Although grease was not part of the original manufacturer’s design, It does minimize leakage and will provide some gear lubrication. Problem is that it tends to “pool” in one location which limits its ability to provide uniform lubrication. It is difficult to flush out without disassembling the steering assembly. If you are pressed for time, you might consider adding some cornhead grease, as I have heard it flows better than regular grease.
2). Grease the throughout bearing with very cheap grease that will allow the oils to separate. Also check the height of the clutch fingers from the bottom base plate, and make sure they are all at the same height.
3) I just checked my brake shaft and it had the same hole, without a cotter-pin and washer. I believe that is normal.

Hi,
The throwout bearing looks good, lots of graphite still there. Check the graphite for being flat on the front side, except for maybe a little wear into it from the fingers, and check it for cracks.

You could also wipe a thin layer of grease on the front surface of the throwout bearing. Part way around is ok, the clutch fingers will spread it around.

The hole in the left brake shaft is supposed to have a cotter key in it, and a washer between the cotter key and the brake pedal mounting. The washer and cotter key keep the left brake pedal and shaft from moving to the right.

Below are pages from the Cub parts manual, showing the shaft, number 8 in the pic. Then on the 2nd page at the description for number 8, it lists the cotter key, and washer. They have evidently made a mistake in the ID of the washer, the shaft is 3/4" on my Cub.
The OD of the washer shows the right size.

My Cub has the cotter key, and washer on the shaft.

Glen, thanks for calling my attention to the parts manual in regards to the brake shaft cotter pin and washer. Now I know mine is missing those. I did review the parts manual for a 49 Cub, and it does list the correct washer ID at 13/16”. It also identifies the washer thickness as 10 Ga.

For the steering gear box, bill is exactly right. But I recommend cotton picker grease instead of corn head grease. Corn head is #0 while cotton picker grease is #00. Little bit thinner and flow better but still thick enough to be grease.

Cotton Picker grease and Corn Head Grease? Never heard of these. Would Tractor Supply have these?

TS has the “00” grease but they don’t stock it with all of the other oil and grease products. For some unknown to me reason it is with the 3-point hitch parts. We have 5 TS stores in our area and that is where all of them have it. Most of the employees don’t know where it is.

Yep what clownfish said. Around here they stock it. But then again we are in cotton country.

My Ariens Snow blower has a high speed worm gear drive for the auger. The recommended grease is their "Ariens Liquid Grease". It comes in a squeeze tube. That should work good for you.

One comment, after you grease the TOB and check/adjust the finger heights, make sure you have the proper gap between the TOB and the fingers. You don't want them constantly touching (as it appears in the photo) or too far apart. If you have the later style adjustment for this, it is done at the clutch pedal. The earlier ones are a bit more difficult, but I don't have personal experience with them.
