grease fittings

[reddog6601]

I have a 1635 with a factory cab. Under floor mat on either side of the hump under the dash is a rubber plug. Behind that plug is a grease fitting, one on each side of the hump. I think it greases the shaft that the brake peddles hang on. I think the fitting on the lerft side might be damaged because I can't get to take grease, it just oozes out from around the fitting. It is in such tight spot that I am afraid that if I can get it out in hopes of replacing it, I will never get a new one screwed back in without making a huge hole in the floor. Has anyone ever had to work on them? I think the fittings were installed first then the cab was set in place. I can feel the grease gun snap on to the fitting but it will not take the grease.
Thanks

You need to get a small shorty socket that will fit on the fitting and take it out to replace it, then see if it will take grease. You may have to heat up the shaft a bit to melt the many years of hardened grease that is already in there.

You could try a "Grease Fitting Cleaner" like this: IPA Grease Fitting Cleaner | Hoses, Valves Fittings| Northern Tool + Equipment. I haven't had much luck with the one I bought, but it might work for you.

I had one on my tractor that was painted over. Had to be done at the factory, because I bought the tractor new and never painted it. I removed the fitting and cleaned it up with my pocket knife, blew some solvent through it and it worked fine after that. You might be dealing with a similar problem. If you can get a grease gun on it, you should be able to get a deep socket wrench on it.

Best luck.

The fitting on my 1734E brake pivot is similar, in my case it feels like it is not taking any grease but since I can see the ends I noticed that it was in fact taking some. I think the tolerances are so tight that it is really hard to squeeze the grease into it.

Thanks for the info. I can't get a socket on it because it is a 45 degree fitting and I hate to use a tool onI it that I have to hammer for fear of breaking the fitting. Then I will be in big trouble. I think the only thing to do it to inlarge the access hole so I can get more of a swing on the wrench

A lot of the 45 and 90 zerks are two piece. You can unscrew the little nipple and then fit a socket onto the body. At least from what I have encountered.

IF you have a second socket of the same size as the fitting you might try cutting the socket lengthwise from the open end up about 1/2 way. I am talking a 6 point socket here. That will allow the bent part of the fitting someplace to go. The torque on grease fittings isn't all that much. It is just a thought.

Everybody has, at one time or another, had a "difficult" zerk. Rather than trying to remove it - I would use a heat gun or the wife's gun style hair dryer to heat it up, melt the old grease and see if it now will accept new grease. I hesitate to suggest the use of a propane torch because of possible fires.

Also, have a helper sit on the seat depress the pedal and then see if the zerk will accept grease. Many times the moving of the internal hole to an alternate location - by depressing the pedal - will allow the zerk to accept grease.

Good point, I had forgotten about that.
