A Alemite volume compressor produces 500 psi max. A Alemite battery powered grease gun will produce 10,000 psi max. So one sees why a grease gun can easlily destroy seals.

Hi, G2D2.
They're YOUR track rollers AND you HAVE been told about the perils of using a normal grease gun to fill them - an electric or air powered grease gun is WAY worse - so if you want to use your electric grease gun on them, PLEEEZ, feel free.

BUTTTTTTT, if you come back complaining about blown seals in your rollers and idlers, DON'T be surprised to be greeted by a chorus of, "We told you so."

For quite a few of the people on this BB, it AIN'T quite their first rodeo.

Just my 0.02.

 

You have a wonderful day. Best wishes. Deas Plant.

cotton picker grease or corn header grease. both are ngli 00. any regional fuel distributor should carry the grease or order it in for you not a problem. go to any john deere or caseIH dealer and they will have it in stock or order it in. there are few other greases that are ngli00 viscosity too but picker grease is readily available in all cotton and grain growing countries.

oh and DONT use a cordless grease gun unless you make a relief adapter like i said you will blow the seals at least with a manual gun you have a chance to feel when its full.
from memory the pressure is no more than 12psi i read that in another topic cant remember which one.

yes cat use the larger 7/8th button head fittings that are 3/8th NPT thread remember that all the threads one these old girls are SAE threads all fittings are NPT

I was able to purchase a good bucket Alamite grease gun for $20.00 last year on Facebook Marketplace. The guy had 5 of them and would have sloe all 5 for $20 ea, I only needed one so that is all I bought. I remember as a kid back in the 50's I had the job of greasing the D4's rollers, I remember Dad instructing me to only pump in grease until you feel resistance, you do not want to blow the seal, cause then I have to take the track apart and pull the roller and replace the seal. It is very hard work and takes a long time so you be careful. I always was. We had a disk plow that had button head fittings too, same advice, do not over pressure, you can feel a sudden increase in resistance, STOP, so you do not blow the seal. Sound advice.

Thank you all ! I will look for a old hand pumper for the grease! A pressure relief valve would be nice but On a quick search I came up with mixed results. However if I take the bolt out on the other side of the rollers the grease will just ooze out when it’s full?! I’m a noob when it comes the the tracks and I did order a operation and service manual yet to arrive. Thank you for all the Sage advice!

Hi, G2D2.
As I understand it, the low pressure volume gun intended for the job has enough pressure to push any air out of the roller past the seals without damaging the seals themselves. If you pull the bolt/plug out of the other side, you are NOT gonna get the full fill.

There were some pretty smart cookies 'figgered' all this out close to 100 years ago and it has worked for all of that time since. Is there any need to 're-invent the wheel'?????????

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

This is what I found 
www.amazon.com/Alemite-7118-1-Alemite-71...strial%2C170&sr=1-19
It's for loading grease guns but produces 500 lbs Probably hose it up and throw on an adapter expensive but...

That is much better than a regular grease gun but think about the gizmo on top, moving it around, keeping the lid on, making a handle etc. Why not find a used volume pump and be done with it? It appears you are trying to make an easily solvable problem into a difficult one.
