Need help identifying "hole" in undercarriage of M925A2 M939

[PapaPumpSD]

Hi all,

I was inspecting the underside of my M925A2 yesterday and I noticed a threaded hole that appeared to be missing the bolt. Is this normal or am I actually missing something? The photos are near the front axle and the viewing angle is me looking up.

Thank you for your help!

All is normal. Not to worry

Hi av80r,

Is that a vent by chance?

That's the bell housing. The pipe plug that is threaded in just behind it is removed and installed into that hole when the vehicles is forded.

Thank you for the info! I didn't know you had to modify the truck at all before fording.

Thanks porky. I have the manuals but I haven't had the luxury of pouring through all of the pages yet. I recently acquired the truck and I've been making my way though the manual, slowy but surely!

I wouldn't call it a luxury reading the -10 tm , it's more of a necessity as it will save you from some expensive repairs caused by improper use . There are a lot of things on these trucks that don't operate like a civilian truck.

Very well said and so true!!

READING the TMs = NECESSARY + REQUIRED PRIOR to OPERATION.

At least that is what I was told when I got my first MV.

Just sayin'.

Carry on.

I bet it was Doghead that told you that.

My lips are sealed...

... and, unless somehow prohibited, I ALWAYS read the TMs before consulting the SS Forums.
