9/22/12 - I ask that you please add a signature line to your profiles on the Cletrac Forum to help me to determine who is spam and who is not. You don't need to drop everything and do this immediately, but please do it when you get a minute and you are visiting the forum. Just go to http://cletrac.org/forum2010/index.php?action=profile and put something in the signature area. If you no longer want to be a member on the Cletrac Forum, please remove your membership.

8/10/11 - Added a new board: Trucking and Hauling

5/30/11 - Just added several new pictures to the Photo Gallery, including several Alfta Track OC-4 working in snow logging, several from the Chicago Road Show, and some from a logging show (not all Oliver/Cletrac). All these pictures are from around 1963 and were scanned from old slides given to me by my late friend John W. Davis. Go to the Photo Gallery and click on "NEW" to see these pictures. Quality is marginal, but I think you will enjoy them.

2/13/11 - Just added a new board "New members introduce yourselves here".

Folks, I just added a new photo gallery where you can upload your own pictures with descriptions, etc. Right now this is in the beta testing stage to see how it works out. Give it a try, but please keep a backup copy of your pictures just in case we decide to use something else. I would prefer you use your real name on the photo gallery, but if you really don't want to, please use the same username as on the forum. Please put your images into the proper categories and take care when your write out your descriptions and image names so people can search for them. I am learning this as we go. At least at the beginning, I have it set up where the administrator has to approve members. I am afraid we may get porn spam in here if we leave it open. To get to the photo gallery, use this link: http://cletrac.org/photos/

Folks, when you join the forum, or when you get the chance to update your Profile, please be sure to put your location and interests. Filling out your signature would help as well. I've been getting some spammers joining and posting links to sites that are completely unrelated to Cletrac or Oliver, or anything to do with tractors. It would make it easier for me, as well as all the other members, if you guys would put your location and interest in your profile. See http://cletrac.org/forum2010/index.php?topic=1299.msg5184#msg5184

I have been unable to locate a fitting that will allow me to lubricate the wheels and rollers on my OC3.  The fittings are button head and are in very tight places.  I have a "pull" type fitting, but need a "push" type fitting to fit them.  can anyone help?  Or should I put zerk fittings on instead?

Zimmerman has an adapter for the lower roller oil fittings that screws into a standard 1/8NPT grease gun. Remove the existing spring/plunger assembly, secure the hole left at the back of the grease gun with Permatex gasket maker, and you have your oil gun.

Thanks.

I was thinking about using a regular grease gun filled with oil, but I could not find the fitting that fits the button heads.

I got one from our local caterpillar distributer, they also have the pumps but the pump is very pricey. Sam

Thanks, Sam.

My plan is to use a regular spring plunger type grease gun with the plunger out of it and the end cap welded shut.  I see it only working pointed down though...

Thinking it over, why wouldn't a hand oil pump on a 5 gallon pail work once I have the fitting on the button head?

I like the idea of the modified grease gun, might have to try it myself. I don't think the hand pump will put out enough pressure.

We used to use an empty gun, put type A transmission fluid in the empty guy and tested some hydraulic relive valves with them. We never changed a thing on the gun, of course we had a hose on it instead of the metal tube. We had no problem developing 2000 psi.

Not sure about the smaller cletracs, but to properly oil the rollers on my BD would probably require you to fill standard sized grease gun a few times to do all of them.  You should keep oiling until oil runs from the seal to wash any dirt away. sam

has anyone tried using that corn head grease to lube the rollers?  i heard it could be described as real runny grease, or real thick gear lube.  the local JD dealer has it for $2.50 a tube.

I just got an OC-3, ran into the button head problem, read about the corn head grease, so I am using that, but don't have any feedback for you on it yet.  I got the grease gun adapter from Graingers for about $11 locally.  It is a pain to use, need about 3 hands, and I had to pull a bolt out of the front roller to put it on one of the fittings on each side, but it works.

I think I posted this before, but I just parked the crawler on a side hill, pulled the fittings out  and filled the cavities with a pump oiler untill it poured back out, then quickly screwed them back in. Messy, but better than nothing.

Thanks,guys.

I can only find the kind of coupler that pulls onto the button.  It sure would be better to do the track rollers with a push on type.

I think removing the fitting and filling with oil is a good idea.  How about using a pipe nipple with a few bushings or coupling to go to 1 inch to make filling easier?  then putting the fittings back in after filling?  The fitting looks like it has a small pipe thread.  Any idea what thread it is?

The original roller shafts button head zerk thread size is 1/2" fine thread, the zerk on the front wheel and track frame hangers are 1/4" pipe thread. if you have any of our new roller shafts, the thread size on those are 1/4" pipe thread.

on mine you can tourn it around as there is a blanked out hole on the oposite side to the pipe going into the fitting. Sam

The regular zerk grease fittings work just as well  as the buttonheads - except - being pointed they are damaged more easily, and they sometimes require two hands to use instead of one.  There are many places you can buy buttonhead fittings, and greasegun adapters.  John Deere is one.  Deere also sells "cornhead grease" which is formulated for applications like track rollers.  Deere used to market it as "track and roller" grease, but it is now labelled as "cornhead" grease.
