Grinding when Turning

[woodlandfarms]

Oh, and the final chapter for today. Everytime I turn the PT it is metal on metal grinding. I was really worried.

I lubed, and tightened the jesus nut and still grinding...

Finally got a can of wd-40 and hit the hydraulic joints. Wow.. guess there is some rust in there.

You have helicopter background? :laughing:

Trying to produce a movie on slick pilots (actually dustoff pilots) from Nam. Couldn't think of a better word than the Jesus nut. So between that, my love for flying and the fact I do do a lot of helicopter work (car commercials mainly), I guess I have some experience with them that most people don't.

Carl has mentioned that he raises his mower up in the air pretty high.

I worked 6 years at the F.B.O. at two local airports. One of the mechanics came out of the shop with a (I kid you not) 6' aluminum crescent wrench! :shocked:I asked him what that was for and he said "tightening the Jesus nut." So, of course, I had to ask what that was. :laughing:

Hee. Hee. That would be like the Osprey, wouldn't it?

Um... at the risk of sounding like a noob, what's a hydraulic joint?

Rob, you are such not a newb. You are dealing with one, that is for sure. I was referring to the ball joints on the hydraulic rams.

My engrish not so good...

Carl,

You may want to put something else in there that has better lubrication under pressure now that you have the joint moving. Magic liquid that it is, WD40 is after all a "Water Displacement" oil (recipe #40). How about some teflon chain lube? Or Terry's favorite SuperLube? Or Triflow? Or Tufoil? I struggle with what the best lube is for those ball joints, since they are down in the water, dirt, and mud, and yet have quite a bit of force on them.

I've been using the dry teflon chain lube on lots of the minor joints on the PT; engine cover hinges, etc. It seems to work well, and doesn't attract dust.

All the best,

Peter

Thanks guys.

I do use SuperLube. It is actually a thin "spray-able" grease that contains Teflon. It has a small amount of solvent as a carrier, which allows it to be in an aerosol spray form. I find that it will penetrate the ball joint, and tends to drive out dirt and moisture, cleaning the joint with the solvent. After the solvent evaporates (which usually takes several hours), you are left with a thin coating of grease and Teflon. I believe this is probably the best kind of lubricant to use.

It's not perfect - I do think that it tends to attract dirt, which is unfortunate, but since I am constantly wiping the joints, or rinsing them (with a garden hose) and then drying and lubricating them again, I am hopeful it doesn't cause a problem.

In any event, my PT is still running like new after 7 years. Granted, I only have 168 hours on it.

Thank you for clarifying that, Carl. I'm sure you're not a noob either... I just didn't know what you meant...

Where are you finding superlube? I have checked some automotive stores and they point to wd-40 and I don't want that.

Thanks

I got mine here:
Ideal TrueValue Home Page
search for Super Lube

I did not realize there is more than one kind which is why the earlier post puzzled me - i have the dry film one which dries in seconds and does not collect dirt at all.

I called the manufacturer. It is retailed by both Ace and True Value Hardware stores nationwide.

I also have the dri-film... I am concerned that it doesn't have enough lubrication for load-bearing ball joints, which is what we have on the PTs. I usually use it for stuff like the sliding door track on the mini-van door.

I agree. I think most of the dry lubes don't have enough pressure resistant properties. That's why I've shifted toward the dry chain lubes- they go on in a solvent and dry to a film, but they are rated for extreme pressure. Mcmaster.com, part # 8710T35 is a dry teflon chain lubricant with molybdenum high pressure additives. (Just below it, they have the kit to lubricate your throttle cable, #1437K1)

All the best,

Peter

What do you guys think of these products?

DuPont? Teflon? Dry-Film Lubricants

I use the Dupont Teflon Multilube on my PT joints now. I used to use Super Lube and found it did a poor job on my Leatherman scissors. I don't know if they compare in lubrication needs, but it seems to me that if Super Lube cannot lube scissors, then it's not good for my tractor. We need some real test data or long term experience. Anybody seen any.

 

[ponytug]

I use the second one down, the teflon chain lubricant, cross referenced to the McMaster-Carr # 8710T35. It seems to work well. You do have to shake the can pretty well to get the teflon in suspension.

I have never seen comprehensive data. Tufoil used to have some on their website, but I don't think they do any longer. I used to dissolve the tufoil 50/50 in some solvent and put it in a sprayer. It still is the best thing I have found for lubricating under corrosive conditions, but it is oil based and therefore attracts dirt.

I do know that it is very hard to get the DuPont name on a product, so I do take it as something of an endorsement.

Here's an interesting review.

DuPont Teflon Chain Saver - DuPont Teflon Chain Lube - webBikeWorld

 

[BobRip]

Interesting review, but as usual with lubricants there is no measurement of wear on one product versus another.
When I put the Super Lube on my scissors, after about 10 to 20 operations the scissors were sticking again. With the Du Pont Lube I cycled them about 80 times and they worked fine. I quit cycling at the time and quit using Super Lube.
