What size nut is the transfer case fill port and the tranny drain and fill port. I have the transfercase drained and I don't have the size wrench to get them off.

 

WRENCH LIST:
Transmission: Fill 17mm, Drain 24mm (15/16" if you do not have 24mm)
Transfer Case: Fill 24mm (15/16" if you do not have 24mm), Drain 17
Front Diff: Fill & Drain 24mm (15/16" if you do not have 24mm)
Rear Diff: Fill & Drain 24mm (15/16" if you do not have 24mm)

CRUSH WASHER LIST (I.D.):
Transmission: 11/16
Transfer Case: 3/4
Front Diff: 3/4
Rear Diff: 3/4

 

You should never need a SAE wrench to get off any of those bolts. I understand there close, but just use the right size.

Besides...that wrench list is wrong

It should be a 24mm Wrench/socket. The bolt itself is a M18x1.50 thread pitch. That is the exact same for the front/rear diffs, the transmission, and the Transfer case fill/drain bolts.

Yep, 24mm if you have it. Right tool for the job eh?
I don't have a 24mm wrench, so closest is
(15/16 inch) / (25.4mm/inch) = 23.8125mm >> 24mm

Thanks for the help guys, I didn't have either so I went to the local pawn shop and found one for $1. There still is deals out there just got to look for them. Thanks

 

Uh, yeah. If you think deals can be found in pawn shops.

Or, you could get a set of IMPACT sockets brand new for avg $1.30 each. http://www.harborfreight.com/10-piec...set-67899.html Keep the set together, and you won't be fishing around that old ammo box looking for the right size wrench.

Your choice.

 

Good deal and good idea. Never mind the snobs. Wrench list revised to be "proper". Snobs happy now?

 

If I don't have a 15/16", can I use a pipe wrench?

I hate to be a "snob," but using the wrong sized wrench on your $2,000 vehicle is just wrong. If you're going to go to the trouble to get the right transmission fluid and the correct gear oil, why not just get a set of wrenches you can use on vehicles (do you know of any cars/trucks made in the last 30 years that use SAE wrenches? My 1974 Ford Mustang II was all metric.)

 

Is there anything wrong with using an SAE wrench/socket on metric hardware? No, as long as it's a tight fit. Have I done it in a pinch? Hell ya.

But...these old trucks are mostly if not all metric. If you own one, why in the hell would your first advice be to use SAE tools on it? Whatever works, works, but I don't usually eat soup with a fork unless I have to. If that makes me a snob, so be it.

 

Pipe wrench works best to remove them. Then throw them away & replace with Marlin Crawler or WabFab Allen wrench models with the built in magnet.

 

Sorry guys. Bad joke but really just kidding see the ""
Seriously now, My Craftsman set from 1986 (still in great condition) did not have the bigger metric sockets, but it has the15/16" that's actually a tighter fit than 24mm.
Happy weekend,

Sorry but...

Don't like to cut a steak with a butter knife
Don't like to take a bath with dirty water
Don't like to shovel snow with a rake
Don't like to take a knife to a gun fight

I could go on and on, but the point has been missed by you. Use the right tool for the job. Period. There is no excuses for not having a metric socket set if you do your own work on your truck. Harbor freight sells them for dirt cheap. It's too expensive to be cheap.

 

One more time...?
