D7 17A track lubrication

Thanks,

After re-reading your thread, I am thinking you may also have another type, if they are not the buttonhead fittings, I understand that these require you to take out the plug and fill with 30 Wt. oil.

The button head type have a hex shape under the button head a flared kind of mushroom shaped head that the Alemite coupler slides over and attaches to, pressure forces the check valve to open in the middle, the other later type is just a plug if I am correct I do stand to be corrected here, see if you can determine if it is a button head or not and definitely refer the the manual for your serial number tractor. Might be an upgrade and not in the book. I'm not sure about lifetime rollers, if they are one in the same that use the 30 wt oil, I think modern ones are sealed completely. Taking a stab at it here, correct me if I am wrong. First there were the alemite type, I forget what came next and if it is applicable to the 17A series, and is the one that takes 30 Wt., but if the older button head type, that is the procedure. This gets asked a lot, many different preferences on the alemite types,as to what grease can be found and used, as well as what is used to pump it in, you just have to be careful and not use too much pressure on those, I have not done or used mine in awhile though, used to lube them lightly as I wanted to play it safe with the seals, and I was not running it heavily, you certainly want the rollers lubed even if the seals leak.

I see them often, most look well used, but are reasonable, I recall someone on another board found a cache of these in AZ, all were N.O.S. still in the box, amazing what people hoard, and in the condition described he could get quite a bit for them now I would think. There are other means to lube these, like a regular grease gun, with the button head adapter that you can get from Cat, with the pressure relief valve, you would need to speak to someone who has used one of these for this purpose instead of the big volume pump, really need to pay attention and not over pressurize it, blowing out the seals. I recall someone stating that you shouild be able to feel when enough is enough, but that is all I know about it so far.
