Mojave shock end cap screws rusted

[KB34]

People interchange them but don't know the exact definition of either one..... OK.... End rant by the Mechanical Engineer....

Seems some folks mix up engine and motor as well along with spelling errors, mostly with synonyms.
[/QUOTE]

Yea people use them interchangeably and I’m not normally one to get nit picky about which is which, unless I’m corrected and the correction is wrong lol. Then I get nit picky about calling one the other.

Either engine OR motor are correct. Technically, it was motor first.
Motorcycle or enginecycle?
Motorized bike or enginized bike?


The text below is from MIT - and there's even more out there confirming, you DO have a motor in your Jeep with 3.6 but you don't have an engine in your vacuum cleaner...... it's just car guys that INSIST motor is incorrect. Motor is correct - I guess it just sounds so wimpy to those who can't handle using such a word to define what provides the motive, the motion, to their big truck. How dare they call it motor!

What’s the difference between a motor and an engine?

As technologies and devices evolve, language must stay on its toes if we expect to understand each other when we talk about them. English-speakers are particularly flexible at adapting to progress. They’re willing to coin new terms, modify old meanings, and allow words that are no longer useful to pass from common usage. “The etymologies of ‘motor’ and ‘engine’ reflect the way language evolves to represent what’s happening in the world,” says MIT literature professor Mary Fuller.

The Oxford English Dictionary defines “motor” as a machine that supplies motive power for a vehicle or other device with moving parts. Similarly, it tells us that an engine is a machine with moving parts that converts power into motion. “We use the words interchangeably now,” says Fuller. “But originally, they meant very different things.”

“Motor” is rooted in the Classical Latin movere, “to move.” It first referred to propulsive force, and later, to the person or device that moved something or caused movement. “As the word came through French into English, it was used in the sense of ‘initiator,’” says Fuller. “A person could be the motor of a plot or a political organization.” By the end of the 19th century, the Second Industrial Revolution had dotted the landscape with steel mills and factories, steamships and railways, and a new word was needed for the mechanisms that powered them. Rooted in the concept of motion, “motor” was the logical choice, and by 1899, it had entered the vernacular as the word for Duryea and Olds’ newfangled horseless carriages.

“Engine” is from the Latin ingenium: character, mental powers, talent, intellect, or cleverness. In its journey through French and into English, the word came to mean ingenuity, contrivance, and trick or malice. “In the 15th century, it also referred to a physical device: an instrument of torture, an apparatus for catching game, a net, trap, or decoy,” says Fuller.

In the early 19th century, the meanings of motor and engine had already begun to converge, both referring to a mechanism providing propulsive force. “The first recorded use of ‘engine’ to mean an electrical machine driven by a petroleum motor occurs in 1853,” says Fuller.

Today, the words are virtually synonymous. “Language evolves to take on new tasks,” she explains. “Without thinking about it, we adapt to new meanings and leave the old behind.” We talk about our computer’s dashboard, unaware that in the 1840s, the word referred to the board at the front of a carriage that stopped mud from being splashed on the coachman. Similarly, the term “search engine” harks back to the older meaning of “engine” as a contrivance, suggests Fuller. First used in 1984 to mean “a piece of hardware or software,” the phrase may have been informed by Charles Babbage’s 1822 use of “engine” to mean a calculating machine.

An engine is a kind of motor that uses heat to generate power. Or more explicitly convert heat energy into mechanical energy. The heat for an engine usually comes from chemical energy.

After the chemical energy comes thermal energy from the combustion and after combustion comes mechanical energy Wich.......AND Wich turns into mechanical energy and bam your truck moves forward ........
This thread is slowly starting into a meme page instead ?

Your definition. As I pasted before - MIT says otherwise.
Interesting how people on fakebook and in forums are the ones saying "if it burns gas it's an engine" while colleges/universities, including MIT, and dictionaries say otherwise.

When the internal combustion engine was invented, the term motor was initially used to distinguish it from the steam engine—which was in wide use at the time, powering locomotives and other vehicles such as steam rollers.
The term motor derives from the Latin verb moto which means 'to set in motion', or 'maintain motion'.
Thus a motor is a device that imparts motion.
Rocketry uses the term rocket motor, even though they consume fuel.

And from another source -

Engine:

A machine for converting thermal energy into mechanical energy or power to produce force and motion.
A railroad locomotive.
A fire engine.
Any mechanical contrivance.
A machine or instrument used in warfare, as a battering ram, catapult, or piece of artillery.
Obsolete. An instrument of torture, especially the rack.

Motor:

A comparatively small and powerful engine, especially an internal-combustion engine in an automobile, motorboat, or the like.
Any self-powered vehicle.
A person or thing that imparts motion, especially a contrivance, as a steam engine, that receives and modifies energy from some natural source in order to utilize it in driving machinery.
Also called electric motor. Electricity. A machine that converts electrical energy into mechanical energy, as an induction motor.

Another thread ruined…

 

[rubber_ducky]

I disagree that the thread is ruined… I still find it quite entertaining. I can’t wait to hear what the dealership has to say about the demand for replacement units.

perhaps the request of a single individual will force Fox to find a suitable alternative screw. Then we all win!

if a previous poster was correct that the screw is a bung for a nitrogen charge, Fox use small nylon screws/plugs on their mountain bike shocks for this purpose. These are great wrt corrosion resistance but they likely wouldn’t stand the test of time on a vehicle that is orders of magnitude heavier, more oil displacement, higher shaft speeds, etc.

Anyway, I hope that it works out to the OP’s satisfaction.

I wonder how much pressure these are under internally - and what the function of THAT screw is. That's what I'm really waiting for - and his resolution.
I'm especially interested in some of that because I do plating for restorations - the finish and how it lasts is more than important - correct finish and lack of rust is a must, even years down the road.
Since the OP is involved in finishes and so on, I'd love to see the specs and how this one failed.
And Jeep should be interested, too.

Hmm. Thanks. I learned something.

As a fellow Engineer, you are picking the fly shit out of the pepper on this one.

 

[JeepCares]

While swapping out my plastic bumper on my Mojave I noticed the end cap screws on the fox remote reservoirs were completely rusted. My Gladiator only has 850 miles on it. These definitely did not pass the FCA/Stellantis salt spray test requirements. I will be taking it to the dealer this weekend and getting them to order new shocks and replace these.

I haven't checked the rears yet, but will do it this afternoon.

Mojave Owners, I would suggest you check yours out as well. If they aren't rusted yet, they might soon be, so keep an eye on it.

@JeepCares

Thanks for tagging us and bringing your concerns to our attention. Feel free to let us know how your appointment goes and we can provide extra support if needed.

Assuming these screws are just caps to protect the nitrogen fill ports ...
I think I'll wait for the TSB to come out on this one, then just order the 4 new screws and replace them myself.

 

[bac]

Sorry to wrestle this thread back on track, but I just checked my Mojave and found rusted screws like the OP.

Waiting to hear the outcome.

2200 miles. Build date of early June 2021.

 

[Radio Guy]

How bout if someone could post the screw size and type so we could all order some in stainless and put the rust problem to bed?

Just take one out, walk into Lowes and use the metric thread selector they have in the hardware section to determine what it is then just buy four of them while you are there in SS.
