An Overlooked Maintenance Item
« on: July 09, 2013, 12:02:35 PM »
Overlooked, neglected, or simply did not realize that it was there.  Fine sawdust and ATF had compacted tightly between the Teflon pads on the mast.  So tightly that it took a screwdriver to pry and loosen and remove it.
 

  
The spaces between the pads were completely compacted with powdered sawdust.
 

 
I'll be sure to keep these overlooked spaces opened up.  Heck, I can even squirt ATF in there now.   ;D

   Better watch, the head might wobble around a little now without that extra padding.

No doubt that is a collection spot, I use short pieces of banding to keep it clean, air would work as well, I do allow a little to build up, kinda figure it works like a wiper when soaked with atf, might be a flawed concept, david
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

I got an education from the school of hard knocks to use ATF.  I had a quantity of hydraulic fluid that had lost its label and was likely for a machine I no longer had so I used to oil the chain,  mast and anything else that needed oiling.  The head got to chattering as it went up or down. I figured the gearbox was going out or a bearing on the cog shaft. Talking it over with ElectricAl, he suggested I clean the mast and apply ATF.  I did and the chatter was reduced dramatically.   

I don't know what else may work but I now know what won't work.

Magic, does your mill still have the middle row of pads on the mast, so 12 pads total instead of 8? WM told me to remove my middle row of pads, they were used on the earlier supers but were found to serve no purpose, only the top and bottom pads make contact with the mast anyhow.

Yes, I have the middle pads.   Actually the corner closest to the clutch lever has 4 pads that are spaced only about 4" apart.  This can be seen in the above picture and was the side with the heaviest and most compacted buildup.

I have not had any luck finding a clear picture in the Operator's Manual.

I'd inquire about them to WM, I don't think they even put those ones on the new mills. I ordered new pads for mine, and WM told me at that time to remove the "extras". I did, and found I wouldn't have had to order new ones- the "in between" pads had never even touched the mast, they were in brand new condition. So I have extras now ;D

OK, I thought that I knew the answer since I dug compacted sawdust out from between them, but I made sure today.  My front mast (toward the control box) has four smaller pads on each side.  The rear mast has two much larger pads on each side.

I am thinking that the front mast must carry more of the weight of the Diesel engine.

We use a lot of ATF, enough that we buy in mini bulk containers.

2 gallon jugs are available at TSC  ( Tractor Supply Company ).

I was starting to get chatter in the raising of the head so talked to Garry about it at Woodmizer West in BC which is why I changed my daily application of ATF to dry graphite spray on the mast about 300 hours ago.

I first did a very through high pressure hot wash  of the entire mill with extra attention to the mast area to ensure it was very well cleaned as per Garry's recommendation.

The graphite works much better than the ATF. I won't go back to ATF on the mill any where. ALL other locations that I was using ATF on now get the Ams Oil metal protectant product instead. I find that I have a lot less cleaning to worry about and no more sticking saw dust or chatter in the head travel. Just over 300 hours total since I switched from ATF and very happy so far. Total hours on the meter are 1103.
   
If you ain't livin on the edge you are takin up way to much room. Of course at my age if I get too close to that edge any more theres a good chance I may fall off.

Bandmill bandit,

Back in 1996 we tried some spray Dry Graphite. It went on like spray paint.
On the second day the Mast Tubes gummed up and the head stopped moving.
In places the Graphite balled up.

Sense you have had success with Graphic, we must have not gotten the good stuff you have.
Our experiment was a complete disaster.

How about sharing some produce information.

ok will do but I am a bit tied up at the moment. Will get a pic of the cans too and post em.

Also Garry tole me that a very THROUGH cleaning was paramount to success with the dry graphite AFTER ATF use.

I used a hot foam acid wash at an oil Rig maintenance wash facility and then a high pressure high temp steam rinse.

Gary told me that the graphite would gum up if mixed with the ATF so I made sure to the tune of 150 bucks worth of high pressure, hot foam acid and steam cleaning to make SURE it was gone. My first can was CRC  "Dry Graphite Lubricant" but the one I am on now and prefer is the GUNK Liquid Wrench  version of the "Dry Graphite sec".

There is another product I MAY try soon. It is a dry lubricant that is used in tight tolerance applications   such as VERY large vault type doors and such. It is a bit expensive at 40 bucks a can but i am gona try it.

I sprayed daily for the first 3 or 4 days and let it dry while I was eating lunch. Now I spray a couple of times a week.

Oh well we live and learn.  :P

I used about a gallon of ATF a month before the switch and was having chatter issues with head up down and minor chatter with the log clamp in out up down too some times. Took that apart and cleaned the bushings and had them knurled and then used the Ams Oil metal protectant there. No issues since. My mill will ONLY see ATF on the top rail Felt and if I can figure out a product that will eliminate it there it will be gone there too.
