Is there a set screw on a Farmall 300 worm bearing retainer?

ShawnAgne · Feb 2, 2018

Was getting ready to remove the worm bearing retainer and it is on pretty tight. However it looks like there is a set screw at about 1 o'clock. Is this common?

If you are referring to the shaft that goes towards the steering wheel I am only seeing bushings in the parts list. If you are referring to the vertical shaft, that top bearing is a thrust bearing so it may have some type of setscrew. Some bearings are made with an off set sleeve that goes in them and then turns to lock bearing to shaft, with a set screw to lock it.

Yeah I'm refering to the one for the steering shaft. All I see is bearings also, looks liek there is a screw on mine. Maybe its just a casting anomaly.

Here is a picture of it. It is most definitely a screw.

Does anybody have an idea what it is screwing into?

Thats not really a screw just a casting marker, if you look closely around your tractor you'll find more.

Ok thank you sure looked like a screw head to me. Didn't want to use the impact gun and break somthing.

Weather that is a screw or not, take a soft drift punch and hammer
and give that end cap a few healthy wacks in normal direction of a
right hand thread to loosen it. It has been wacked before from
looks on picture.

The picture is large to be on here, bu to me it looks like a screw someone has put into it either to check fluid level or add oil with a squirt can. If it is in threads they may have had trouble with it loosening and put it in to lock it in place. That is the wrong color metal to be a casting mark.

John you are correct, I can't get a wrench or a socket on the impact driver to fit the nut real well but it is in there tight.

Janicholson · Feb 3, 2018

There is nothing for it to screw into. So it is no way a setscrew. A metric 6 point socket may fit the Hex better than an inch
socket. Jim

Takes bigger than an inch 1 1/8" doesn't fit it and 1 1/4" rotates around those are the marks you see on it. Darn thing is on there tight.

A good penetrating oil given some time to work and a few gentle taps with a hammer to send a vibration thru the metal has worked for me in the past to loosen rusty parts.

Also , both the M I owned and my 400 have that same "screwhead" mark on the casting.

Thanks, wonder why the casting had a screw head mark like that kind of interesting.

john *.?-!.* cub owner · Feb 3, 2018

Never noticed that casting mark on my H, and I am not going to pull the hood nose off to look either. :lol: A large pipe wrench woks good on that cap. If I remember correctly the flats on the nut part are tapered, so nothing fits them real good.

Is there a set screw on a Farmall 300 worm bearing retainer?
