What size is the crown nut holding the pintle?

[TOBASH]

What size is the large crown nut screwed to the pintle. The really large one.

I was told incorrectly that it is 1 and 3/4. That size socket will not fit so I'm out 50 clams.

Before I purchase another I would like to see what the real size is. I need to transfer the pintle to the pintle extension I am placing on the airlift bum,per.

Thanks In Advance,

mine is
1.85"

remove the cotter pin, clean the threads and unscrew it. It should not be on there tight, unless rusted.

Is they, |We, Him, Us, not allowed to do that anymore?

Everything you would like to know about your vehicle is in the TM,s

Action is correct
Really the TMs tell you what size socket to use on bolts and nuts???

The TM indicates in a drawing the part and the next or previous page has the NSN of that part.
Put that NSN into part target and it shows everything there is to know about the part.

Thanks one and all.

I appreciate all the feedback as I was unsure about TM having this info.

RWH, I thank you for the idea about the pipe wrench. I’m like you, but about tools. You usually say when you need a part get the proper part. I usually say when you need a tool, get the proper tool.

I bought and used a 1-7/8 1/2 inch drive impact socket. I had prelubricated the crown nut two or three days ago. The rusted spindle tried to resist, then gave way. I think a pipe wrench might not have worked as I had no leverage with the rear short small bumper off the rig.

Best,

T

I see you have resolved the issue but I wanted to share a trick I use often at work to mearsure diameters or in this case the size of a large nut. Maybe in the future it will come in handy. By placing 2 squares as shown, you can slide them to fit like a caliper and as long as the bottom edges remain in the same line, you can get a pretty accurate measurement.

Just put a breaker bar into the pintle and crank away, most folks dont have a 1 7/8 socket, but many have a pipe wrench or large channel locks, hit it with some heat and it’s off in seconds. I do a bumper a week, it’s become a tedious process on the M1123’s...
