Service on Wood Mizer

[Magicman]

The last I knew they were still pressed in.  I have had to tap and replace a couple mine which wasn't a big deal.  The failures were not due to the fact that they were pressed in.  I broke them off.

I use a red grease and it's a moly grease...
For stopped up fitting I use a grease hammer.

Never seen one of them, must need sandpaper gloves to swing it. Just kidding.....now show me your grease hammer... Merry Christmas

Hello,
  Yes the grease fittings are pressed in. Sometimes we learn which battle to fight and which one to leave alone. Frequent cycling your grease gun on the fitting would solve most of the issue of the fittings coming out. I drill many out and tap with new fittings. 7/32 dill and 1/4" 28 tpi.
I have purchased the grease hammer tool, not had much luck with it.

The grease hammers work great, but you have to fill them with a light oil, I usually just use diesel.

[Kbeitz]

I just use motor oil...

Marty, I don'tremember having any trouble with the grease fittings coming out, but I don't know how many different things I have worked on that has had busted grease fittings, I have even had some new ones here lately lose the ball out of them. What I was talking about, is some folks don't know what to do with a pressed inone, when they might have changed it if it was a screwed in type.

All grease fittings must not be equal. I've noticed that some on my equipment are really nice and fit/work great. Other equipment has rather crappy ones that either won't accept grease, fall out, or just terrible fit.

I'm guessing it's a scale-of-economics issue whereas if the manufacturer can save a few cents per fitting x 10 fittings x5000 units, that's $1500/yr.

Most if not all of my personal grease fitting woes go back to my using what I "thought" was a good grease.  I was talking with a customer who is a logger and he made a comment about all grease was not equal.  What?  I thought grease was grease.  That is when I found out about NLGI #2.  I have not had a fitting clogged with hardened grease since then.

[PA_Walnut]

I always use Lucas Red'N'Tacky#2 NLGI red grease.
On things that require "more", I use Mobile1's or Amsoil Red synthetic.

Dewalt 18V grease gun and a tube of that, equals fast-n-easy joy!! 

[barbender]

I use Mystic Semi-synthetic, in a Milwaukee grease gun. Anytime I have had to remove a pin on the forwarder, they are still wet with grease, and the forwarders only call for a 40 hour grease schedule. Coming from construction equipment, which we ways greased daily, it was hard to get used to greasing just once or twice a week. In fact, I used to try to be a hero and grease the forwarder daily, I finally had to give up on that because I would have grease all over my windshield🙄 The Mystic is good grease, also, the Ponsse machines use the perforated bronze bushings that hold grease very nicely.

These things have grease fittings?  .... (sorry, couldn`t resist

[JB Griffin]

You would need to tell that to the folks that make grease.

The grease that I use on my sawmill says Lithium and Wheel Bearing.
 

 (Image hidden from quote, click to view.)
The key wording is: NLGI #2.  What I found out is that it will not harden and clog the sawmill's grease fittings.

Point taken, but I'm not going to use that stuff in my bearings. I just don't trust lithium grease for bearings,  too much load. Maybe I'm just too old school.

My 15 foot bush hog style cutter had some frozen grease bearings (and other problems) when the service guy came out within the first year, and he zapped some of them with a propane torch to "wake them up".  Only had to replace one if I recall correctly. It's a delicate operation since grease is "probably" flammable.

[starmac]

I will second that all grease fittings are created equal. It seems like the new ones are built cheaper, if that is even possible. The last two spicer u-joints I have put in my log truck had to have one of them changed right off the bat, and even one of the replacements leaked as soon as we supplied grease, so had to be changed out again.

I keep two assortments handy, one in the shop and one in the service truck.

[MbfVA]

I'll bet cheap grease clogs easier in colder climates, too.  Used to buy cheap then realized I wasn't spending/buying all that much anyway, so I went to better stuff overall.  Fewer problems since, it seems but that is not statistically calculated.  Marty's photos are a wake up regardless if you've been skipping and/or skimping.

If you have lots to grease, might pay to buy a drum(s) and pump your own if you can settle on one type for your stuff?

[4x4American]

I been using schaeffer’s moly 238 supreme for a good while I had bought a case of it and boy thats some tough grease great for pins I’ve never seen a harder grease out there.  But lately in this cold I been using some of that Lucas red n tacky cause its easier to pump.  Also have some of that mobil stuff.  Good grease is good grease I reckon

[MbfVA]

When you say mobil, are you talking about their synthetic?

[PA_Walnut]

Mobile1's synthetic is excellent....well, I think all of the good brand synthetics are. It's super-cheap "insurance" so I use good-quality grease and grease often. Well...err....truth be told: I'm just excited to use my Dewalt electric grease gun! 

I grease my tractor's loader, front end, and the mill's arms every 10 hours or so. It takes 10 minutes.
