Been digging through TMs and part #s trying to determine what size socket I need to remove the fill plug on my transfer case to check fill level. I also searched some posts here and saw someone had asked a similar question a while back with directives to research the TMs, crawl under the truck and also a suggestion that it was a 33MM socket. That being said, I have searched TMs finding the part, but no info on size (and I may just be missing), checked NSN part references, checked under the truck (determined that the plug was way bigger than any socket I had already), and searched locally for a 33MM socket, but could only find 30MM, 34MM, & 36MM. I grabbed an assortment to test, just have not done so yet, but planning to this weekend and figured would check to see if any advice here before I crawl back under to test my assortment and find none fit.

33mm is close to 1 1/4 , maybe 1 5/16 standard sizes try them
Thank you...I did grab an SAE 1 1/4 in my assortment, so glad possibly heading down right path.

Even overhere in metricland, 33mm is an odd size indeed. 32 and 34 are common, but I´ve never seen a 33mm socket in any tool set.

. That was going to be my last resort. Was just worried could tear up the head.

Shouldn't be that tight . Autozone and many others have them ( common spindle nut for disposable cars).Noted

autozone will usually let you try a size to make sure it fits before you buy it. As long as you try it in the parking lot and not at home. Or just ask them to measure it with a caliper for you.

Ah, it´s 30mm on the NP218, too; interesting.
I had to work on my NP242 on Friday, and measured 30mm there. But I wasn´t sure wether the NP218 might have a different plug.
So it´s 30mm on both transfers. Now that´s a pretty common socket size overhere.
