1. [TowerTalk] Belt Slippage on LM-470 Towers (score: 1)

Both my LM-470s tend to slip when I attempt to raise them, especially in cold WX. I have tightened the belts about as much as possible on several occasions. In one case, wire brushed the large pulley

I have not had any problem with the belt on my '470 slipping, but then we don't have cold WX in Arizona <grin>. It could be the clutch on the driven pulley that is slipping, and that is adjustable. J

Rubber begins to decay almost immediately after it is pressed into shape. That is why tires on RVs although they have only a few thousand miles have to be replaced. They aren't safe after more than t

The hub of the driven pulley is a clutch. This is true on my LM-470 and was true on my HZN-354. (Not true on my Tristao TX-455). What I call the driven pulley hub is mounted on the keyed worm gear th

Paul... Interesting. I'm gonna send a photo to your email address, would like to see if you can steer me to what you mean by "hub of the driven pulley is a clutch". I either have no clutch, or it is

Thanks, Paul, Dan, Skip, both Daves and Roger. To answer several questions, I had recently changed to a new belt, applied grease to the drum via the fitting and changed the gearbox oil. Frankly, I ma

It could also be that the belt is too narrow and rides in the bottom of the pulleys. The belt dressing is a good idea. Even if it slips when first applied it will (should) reduce slippage in the futu

I have several spare belts on hand here: 4L-420 (1/2"X 42"). Not sure if that's the size I'm using, or these are leftovers after having switched to a smaller belt. I do recall switching to a smaller

Well, I changed the belt this morning to one 1/2" shorter. Frankly, it still slipped until I removed the residue remaining from the Belt Dressing on both pulleys with alcohol. The temperature was abo

Back on the farm a long time ago, before grinder/mixers, there were John Deere tractors with belt pulleys ('48A) that we used on the old hammermill. (Am I old or what). Belt dressing was used on the

The last time I bought a belt for a tower motor, I got it at an ACE Hardware store ... they had a large selection, and it worky-worky swell! Mark AA6DX -- Original Message -- From: "k0dan" <k0dan@com

Jim, several people have insisted that the Belt Dressing does indeed reduce slippage. I may have used too much or not waited long enough for it to dry. I am going to check the local farmers' supply f
