The Alemite 4015 A4 is the one you want - name brand and 1,800 psi.

The best price I found was here - https://www.autotoolworld.com/Alemite-4 ... 80203.html The problem with auto tool world is that they don't send notifications or shipping info and don't answer the phone or reply to emails, so I thought I got scammed and then I bought one off eBay.

And soon after the one from eBay was shipped, I got the one in the mail from auto tool world, so they are legit.

If you want the one that I got off eBay you can have it for $120 + shipping (I paid $140 including tax and shipping). It should be here in a few days.

My grease gun is whatever Auto Zone had 20 years ago. IMO there’s nothing special needed to grease a 350.

I bought a button head adapter from Amazon and grab it whenever I need it without needing multiple guns to grease all my things.


$17…works great for me.

I'm far from an expert, but there are a lot of folks posting about the requirement for a low-pressure grease gun here and Yesterday's Tractors. Here's an example - viewtopic.php?t=12163

I'm using JD Grade 0 corn head grease in my low pressure gun for the rollers and idlers. The pins and bushings get JD moly grease from the Milwaukee M18 grease gun.

Yeah, that’s a good read and good advice. Stan and the guys would know, but I never knew there was a difference…learn something new everyday.

Hi,

A low pressure gun will stop pumping once the bellows seals hit the end of their travel. A regular, high pressure, gun will blow them out and ruin them.

The idea is the light No 0 grease (or heavy oil) will push out as you operate the machine and carry the dirt away from the inside of the rollers. In other words, this application for grease is not like the usual applications one uses No 2 grease for.

The grease and gun issue caused enough problems with folks using the incorrect guns and grease to where the design was changed to permanently lubed rollers. At a higher cost, of course.

Lavoy stocks a low pressure gun and the button head end. Get one and then go to the JD Ag dealer for the Corn Head grease. Get several tubes, as these rollers can take quite a lot of it.

Deere' spec'd gun was 1200PSI, impossible to find that now. I keep 1800PSI guns in stock, best I can come up with.

@Lavoy, is there a replacement part for the main electrical junction block for the early 350 (1969)?

N9, and I think it is obsolete from Deere.
