JD grease gun...

[BCnT]

was reading my newly acquired 350B owners manual and it states that there is a "special" grease gun for dozers...i been around the block a time or 3 and as far as i ever knew a grease gun is a grease gun...whats the difference if any???

Maybe it's yellow with JD on it and sells for double the price of a standard one? LoL Dave

prolly means the special "button" tip that goes on the end of the gun's hose. Its used only for grease added to the track adjustor to tighten the tracks. If your adjustor has the regular Zerk fitting, someone has replaced the originals.

some state " low pressure" grease gun for rollers so the seals dont get blowin out. i dont if there is a real diff in grease guns or not. i use corn head grease couse my seals are shot

They did make a "special" gun. You don't need it. Buy Lubriplate 5555 or cornhead grease and inject it with a tube through the hole. I made a tool that screws in and has a long tube to fill from the back to the front. Below the tube in the threaded plug I drilled a hole to let water out and so that I can't build up too much pressure inside the bottom roller.

The one we got pushes oil or grease. Called a buttonhead zerk.

What they are referencing is the low pressure grease gun for greasing the bottom rollers and front idlers. If you use a standard grease gun, you will have already blown the seals up before you know it. They use a bellows type seal that will not tolerate pressure, it blows the side out, and then your seals are shot.
A pistol grip gun makes it a little easier to fell the resistance, and you are less likely to damage anything.

As Lavoy said, there are high-flow/low-pressure guns, and also low-flow/high-pressure. High flow has a big diameter plunger, and the low flow a smaller one. You certainly can use either if you're careful. I've never had a problem with either. You just have to use a little finese and be careful not to over-pressurize the roller-seals. I can see though that somebody not cautious could blow out a seal pretty fast with a high-pressure gun. If you stop as soon as you feel resistance, you'll be fine.

I got looking at some of my grease guns. I've got three versions. High pressure gun has a 3/8" diameter plunger and is rated up to 7000 PSI. My low pressure gun has a 5/8" diameter plunger and is rated a 3000 PSI max. I have another that is "covertible" and has a high and low setting by changing a pin.

I'm sure more than most people care to know about grease guns - but some specs for guns made and sold under Lincoln and Deere names:

# 1013 and # 1145 - low and high pressure, 1 ounce of grease per 18 strokes at 7000 PSI, or 1 ounce of grease per 33 srokes at 4000 PSI.

# 1037 low pressure gun - 1 ounce per 9 strokes at 3000 PSI max.

# 1035 high pressure gun - 1 ounce per 25 strokes at 7000 PSI max.

all the years i've spent turning wrenches for a living the only difference i knew was armstrong vs pneumatic...evidently a previous owner didnt know any different either cause its got standard zerks everywhere.

Alemite, low pressure, volume pump is what the old style caterpillar Alemited buttonhead fittings required on the old style rollers that you had to lube with a 0 or 00 like grease/oil. As JD says, you can rupture roller seals, say if you fill a common grease gun set up for the fittings you have, some used to use em on the caterpillars, just have to be real careful to feel for that resistance, safer to use the volume pump I suppose, because it is not high pressure, regular grease gun can produce high PSI's etc.

Button head fittings are still around. If you decide you want to switch it back, I have fittings and gun ends on hand.
