Does anyone know if the HMMWV 6.2 pan will fit in our chassis? I just bought 4 rebuilt hmmwv engines and want to know if I would need to swap pans with my current 6.2 if I were to swap one in. Also, is there something special about the Hummer pans? I looked on ebay at them and damned if they are listing 125-150 per pan and I got 3 extras! I went ahead and listed on on ebay for the heck of it, but is there something special I need to know about?
 
I would think they would hold more oil and be made of a thicker steel. But I dont know if they would fit in our chassis.

I just looked up some pics, I'm pretty sure it will fit.

Also, where did you buy the engine from?
 
A guy I know rebuilds engines for govt contracts. Hes got a crapload of engines down there for all kinds of military vehicles. He rebuilt these, the government declined on getting them back and these were the last ones out of that lot that he had, he gave me a price and said thats for 1 or all 4, what you dont take goes to the scrapyard on monday. So I loaded up and grabbed em all. He threw in an extra single plane j code manifold and 3 extra hummer pans.

After I posted this I was dicking around on steel soldiers and someone else asked the same question and the reply was that they would fit.
 
The humvee pans have a different angle at the front of the pan that could possibly interfere with the front differential at extreme articulation but it should fit on a 4x4. I dont know about the clearance on a 2 wheel drive with the A-arm crossmember though. I have a Humvee pan That looks brand new except for the hole in the side of it from where the motor threw a rod. I bought 2 6.5's from GL back in 2007. They both had a head gasket leak and hydrolocked snapping the connecting rod in half. Both blocks checked out ok, sold one and have the other (2001) Block sitting in the garage waiting for a rebuild.
