Drain Plug ?

[tklm539]

Should there be a plug in the drain hole at the bottom of the clutch housing? Mine does not have a plug and I am thinking it should be there.

I have been going through the TM's and have yet to find it.

Thanks

It's only plugged for fording ops, the plug should be in a boss next to it.

You know I can post a picture if you wanted it.

Earlier trucks were to have the drain plug stored in the map compartment for installation before fording. At some point in production, the bell housing casting was changed to include a boss next to the drain hole where the plug could be screwed on for storage, leaving the drain open... My deuce has the boss, my V-18A/MTQ does not.

Check your Operator's Manual in the Special Purpose Kits Controls and Indicators Section , look in Deepwater Fording Kit. Explains it with picture.

Guess I was thinking wrong!!

No boss that I can find. Thanks for the info. I removed the plug that I had put in and a small quantity (back of plug) motor oil came out. Is this a bad thing? I figured it needed a plug there because I saw the oil drip out.

I am new to this but I am pretty sure that I am looking at the clutch. Large round disc shaped housing just behind motor?

Thanks
Tom

Yup... the clutch is in there, and that's why the drain needs to be open. If the bell housing were plugged and the rear seal leaked, it would fill the housing with oil and ruin the clutch. Most deuces seem to leak a bit from the rear seal, I wouldn't worry unless it was real bad.

My favorite quote from Recovry4x4 was regarding the dripping oil from the bellhousing:

R4x4: "Is it a stream?"
Me: "No - it drips"
R4x4: "They're called road oilers for a reason!"

I think that I am beginning to realize that some drips are to be expected. That it is not a brand new passenger car!!!

When it stops leaking... you know your crankcase is empty!!!!!

And, in a related note -

When I was trouble shooting my slobbering deuce (burning oil that seeps past the turbo seals), I found a pretty interesting troubleshooting procedure:
1. Fill the truck's oil up to full.
2. Drive truck on highway, fully loaded
3. Stop periodically and note how long it takes for the dipstick to record 1 quart low.

If the mileage from step 3 is greater than 60 miles, then that is "acceptable oil consumption."

So 60 miles to the quart is OK! Thats good news. If I were driving to Aberdeen that would give me a 20 quart ride each way.

my bellhousing does not have the boss for the folding plug. I have to store mine the the glove box too.

That's great. Everything I own drips something

Thank you search engine!

I know this is kinda old but I was under my new deuce and noticed the same thing and got a little worried. Sounds like I'm good to go by the explanations here.

Just thought I'd bump this topic in case any other newbs out there had the same questions.

Thanks guys, this site is AMAZING!

I will say this,the boss idea was not real bright!Mine has the boss but I broke a breaker bar trying to get the plug out for the heck of it once.That sucker is rusted shut....Making it worthless in a real Military situtation.....I could heat it up with a torch and or take an impact but in the field you wouldn't have access to those tools.....I will just use a boat plug if I ever do something stupid again....like floor deep mud.....

I guess my deuce just likes to slobber out the slobber pipe when Idleing for more then 5 minutes- being as she's normally aspirated, she also does it a little after being run hard without idleing her down, I'll have to check her for the drain plug boss. I know her last owner went fording in 2' of water- I just hope he knew about the drain plug, being a serving Armor crewman in Iraq with III 3/3Cav. So far she's shown no ill effects in the gearboxes and axles, and the knuckle boots are solid.
She does, however, smoke like an EMD GP-9 or Alco RS-3 ( with injectors off set) when coming of a long idle or when accellerating at certain RPM's, and she will bark very loudly at the stack now and then on accellerating (Freight Train will explain the RS-3 to you all), so like the one gentlemen says "We won't be able to sneak up on them, they'll hear our Detroits (but at least I can bring my own smoke screen and obfuscate the matter).
And the Unimog likes to backfire on sharp decellerations- so I can't sneak up there either( I guess that's why the Swiss never attacked anyone with Unimogs)!


Thanks again, Sincerely,

I don't like to "slow idle" an engine. A diesel engine will tend to run cold anyway, and the Deuce has excessive cooling capacity anyway, as does most MV's. When they run slow, they load up, there is incomplete combustion, etc, that leads to oil dilution. The longest I idle any of my engines is at a Stop Light (I have to go 100 miles to the 1st one here). Otherwise, when stopped, pull that throttle out to 11 or 12 hundred RPM, and be happy about it. Watch the complaints listed above, be none existent! They should be running at 190 to 200 f. They will run cleaner there!
