I'm getting ready to lube the chassis. The maintenance manual I have says the coach requires "NLGI - 2 Extreme Pressure Grease". I currently have "NLGI - 2" grease in my grease gun (it does not say "extreme pressure"). Are they one in the same, or is there a different "extreme pressure" variant that I need to use?
Thanks as always ^.^d
It isn't the same. I use 3 different NGLI#2 greases on farm stuff. 2 of them are EP rated and are for different applications.
We used good chassis grease for all fittings, BUT do not put any grease in the 2 grease fittings on the brake caliper and , which take special grease and require special purging after greasing.
So we would use your grease.
Don't forget rear axle U Joints where we try to get grease into both fittings and see some push out of all 4 bearing ends, sometimes by working grease gun with fast pushes.
Also drive shaft splines need grease.
Go for it and have fun under there.
Elliott can you find out if both greases have the same mil spec ?
I don't see it on the tube I have. I ordered some EP grease off of Amazon...probably overkill but it'll let me sleep easy.
To be clear, #2 and #9 in the attached doc are the ones that require special grease, correct?
#2: "Disc Brake Caliper Slide Rails"
#9: "Disc Brake Caliper (3 fittings each brake)
I have the original service bulletin from FT where they clarified greasing the brakes and in there is says they only need to be lubed twice in the life of the pads. Is that still the prevailing conventional wisdom?
" twice in the life of the pads". That could be a lot of miles.
I'm easy on the brakes, on one PU I put over 60,000 before a pad change.
Follow on to Robert & Susan. . .
Thanks to Allison retarder, how about far from worn, original brake pads with 150,000 miles on a 25-yr old coach.
We also exercise brakes by several short hard brake forward & reverse actions before taking off after sitting for a while. Maybe that helps?
BTW, Surprised how many technical questions and discussions are found on a scan of FACEBOOK FORETRAVEL OWNERS GROUP. Facebook format does not seem to work as well as Steve & Michelle's ForeForums. Wonder if many Facebookers do not even use this ForeForum.
I might be missing something in my 16 years of owning and servicing my coach. I don't know of any caliper slide rails#2, and I don't think # 10and 11 use #2 grease.
I have seen FB members come here just to get one problem solved then disappear without even a thanks. I stretched myself on one because I understood that the coach was in a shop on the road and I feel for a person in that fix. It didn't cost me a dime but I did make some phone calls to people that would help me help someone and those people had plenty other calls to deal with. I've been helped a plenty but believe me I remember it and I don't like to bother my sources for nada.
I tried to quote B&C FB comment but guess either my computer or the web page is broken on that part. All I get is XLoading....
I think we could start a new thread on this subject.
What I am seeing is the newer coach owners are going to FB for answers instead of to this forum. I think the reason for that is they know about the Motorcade FB group and then also learn about the regular FT FB group. This is a two fold problem. First there are very few of us with newer coaches on FF (Mine is already 8 years old) Of the ones of us that do have newer coaches, A lot of us do not know a lot of the answers to problems that the newer coaches have. There are a number of the systems that are the same but there are also a lot that are not and FT has a habit of making changes almost every year.
If we could get more of the newer coach owners on here, I think it would help everyone way more then just being on FB. Anyone with ideas as to get the FB people to know about FF? I do not have FB but my wife will bring to my attention to some of the problems people are having that she things I might know the answer too. I try to also direct them to this site.
Didn't mean to go off topic, sort of followed Barry's comment. I see no "problem" on my part that a please or thank you wouldn't fix. Back to the OP, I've greased equipment for a long time with plain old "red grease" it has served me well in every application until the HD Meritor caliper "requiring" clay based grease so I bought it. Teach me something here, all I can imagine as a difference in PM grease and clay based grease is temperature without failure reads to be higher on the clay base. I have purged red pm grease out of a meritor caliper with clay base and the pm grease was still soft and pliable. I'm on board enough with the clay base to have spent 25.00 a tube for it and suppose I will continue. Temperature isn't my concern vs staying pliable because I don't plan to get my brakes hot enough to damage any type grease. I'm a curious sort, ok with a change I just like to know why in Detail. Probably a dumb question but I bet other inquiring minds would like to know.
What I do is answer them by saying go to the forum,my thinking is it's just easier to be on facebook then the forum,my thinking
on the newer coach thing is the guy with a brand new coach is not going to work on it,Brad's was a 2010 and he paid a million
for it,there are exceptions but if I had a newer coach and could afford to someone else would be working on it.
One thing about Facebook and not here- I have to delete lots of trolls hawking deaths of celebrities and their T-shirt ads.
FWIW semantically slide rails and slide pins are the same thing.
I don't "do" acronyms so I looked up "Googled" NLGI:
"The National Lubricating Grease Institute is an international trade association that serves the grease and gear lubricant industry. It exists to promote research and development of lubrication technology. It also publishes industry standards for greases."
And also found:
?What is the difference between NLGI #1 and #2?
NLGI #1 Grease versus NLGI #2 Grease"
"Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications."
And from memory:
And for Dub' question, Bentonite Clay. The special caliper grease is thickened with bentonite clay and without that specification a manufacturer could be using chopped manila rope.
For Elliott, you dun good kid. There's petroleum based lubricants, synthetic lubricants made from propane, and high pressure additives. Those king pins need the high pressure additives. Again from memory think of a range of adulterants from lead to molybdenum. sulfur compounds are somewhere in between and do nasty things to brass and bronze.
