Disassemble geared hubs

[Mogman]

There's a pinion gear in a hub??????????? Too much time on the beach is my guess.

Well golly gee, look what I stumbled across, AMG calls these pinions also

Goes to prove even AMG can be wrong.................

Pinion Gear – A pinion is the smaller of two meshed gears in an assembly. Pinions can be either spur or helical type gears, and be either the driving or driven gear, depending on the application. Pinion gears are used in many different types of gearing systems such as ring and pinion or rack and pinion systems.

The small gear attached to a motor is referred to as a pinion gear, think starter or small dc motor. The small gear attached to a "shaft" is referred to as a spur gear. JUST my 2 cents.

Every definition I can find online just says the smaller of two gears. It doesn't specify it by any applications.
The definition I find for spur gears is gears that are on parallel shafts.
According to that, it can be both a pinion gear AND a spur gear in this application.

Just started raining here, and I'm supposed to go help my ex wife move to a different apartment. She's moving into a 4th floor apartment, so 3 flights of stairs with her furniture. I'd rather be mowing the grass.

That is just wrong, spur refers to the type of teeth a gear has not its application.
What about a ring and pinion gear, no small DC motor there.

This is probably similar to the difference between cranking an engine and turning it over.
On more than one occasion I've read where someone's engine will crank but won't turn over, or will turn over but won't crank.
To me both mean the exact same thing; when you crank the motor you are making it turn over.

I guess this shows when one makes a comment with the INTENT of making another person look stupid it can certainly backfire.

I thought it was pretty light hearted until now, didn't mean to offend you. Me thinks your skin may be a bit too thin. Just my 2 cents.

Pinion gear in my book !!!

A quick trip to the TM will reveal it’s referred to as “upper spur gear” and it always has been…at least it has in the 25yrs I’ve worked on them,.

I rest my case. And I am not going to discuss what the bearing on the front drive shaft is called either.
BUT, I do want to apologise to VAPOR TRAIL for hijacking his post to air our silly BS to argue about a GEAR. My hat is off to anyone ambitious and talented enough to tear one of these down and repair it!
Hope everyone has a nice day.
THANKS STEVE

Both of the gears in the hub called spur gears and that is technically correct, if you live in the narrow minded would of the HMMWV only then I can understand, but the rest of the mechanical world understands what a pinion gear is.
Even the folks that built it called it a pinion gear.
EDIT: To say it is a spur gear is correct, to say it is not a pinion gear is just plain wrong.
I wonder what the TM calls the helical top gear, to call that a spur gear would be incorrect.

LOL, you’re just looking for an argument, not interested…but you’re an expert on everything now that someone gave you mod access.
When a customer calls my shop and is looking for this part, and they do, they ask for the upper spur gear, that’s it…plain and simple, no one in 25yrs has asked for an upper pinion gear, I frankly don’t give a s**t what all the other part names are because I have to go look it up to get the part number, in the PDF using “spur” which produces results….
Now run along

So why do you care so much about what I call it???
I'm not going anywhere!

Tomato....Tomahto. In a salad or on a sandwich, All tastes the same.

Extra pickles please, CAMO

 

[Vapor Trail]

My thread was meant to be informative for something that there is hardly any information on at all and it turns into this?

 

[Milcommoguy]

There are plenty of videos on YouTube of assembling the portal axles hubs but none that I found of disassembly. I’ve got the gears out and all the plates off but I don’t know how to get the spindle bearing off and the small gear bearings off without hurting them. Any help would be appreciated. Thank you

From gears to pickle's... I thought there was a lot of great information shared. Once and a while the guys in the shop will hide a lunch pail or toss a wrench.

OK, which one of you monkeys ate all the pickles.

Just another day on the internet shop floor, CAMO
