Oil drain valve

[JonM934]

I did not like the process of changing the oil on these trucks. Having the oil shoot out the side of the oil pan and head straight for the tire seems like a bad idea.

Also, I am using 5 gallon buckets and the Cat C-12 holds a lot more than one bucket so then I had to switch buckets while the oil is flying out. Not much fun.

So I thought I would suck the oil out by using a transfer pump. I have done it with other vehicles and it is a lot cleaner but not a lot faster.

So I had a transfer pump and a large hose so I stuck the "suck" end into the fill tube on the engine. Then my plan fell apart. The hose will only go a few inches into the fill tube before it hits something and it cannot make it all the way to the pan.

Dang it.

So my plan B was to just bite the bullet and drain the oil the regular way. BOY! It made a mess.

Awhile ago I found a place selling the oil drain VALVES and I had seen them before I thought it would be great if they made one for the 7 Ton. THEY DO!

I bought one and it works great. Now I can turn the draining oil off and switch the 5 gallon bucket. Then turn it on again to finish draining. They also sell a hose that attaches to the valve so I can drain the oil right into the bucket without it ever getting onto anything including the floor.

So while the engine was empty of oil, I installed the valve. My next oil change will be fast, simple, and clean. I installed my valve on the passenger side drain plug because it seemed to have a little more room. Here are the photos that show everything.

This is the package for the valve and I also show the drain plug it replaces.





I know I used a lot of gasket sealant but I do not want it coming off.

This is the hose and a 90 degree fitting.



Better shot.

I could use the 90 right at the valve and then the hose would point straight down but it seems better for me if the hose is by the tire because then it is easier to get the full bucket out from under the truck.

Here are the Fumoto.com part numbers.

One thought...

Everyone has an opinion, but I think you need some sort of safety wire to hold that valve in the OFF position. Truck & Motor vibrations and a valve that dumps the "life giving fluid" out of your truck really fast could cause a really bad day!

The valve has a couple of features to prevent the valve from moving by itself. No safety wire is needed.

Guess it does make things easer but how will it fair when off road. Seen someone put one on a Deuce and with the bottom two drains on the Deuce and going off road a good size stick or a rock could knock it off. Looks like at least on your truck the drain plugs are on the side of the pan and a little more out of the way.

I use them on all my trucks and they work great. I like that you can add a hose and go right into a 5gal. bucket. There is a little plastic clip you can get form them that will keep it from being opened.

Nice but it’s gonna leave a gallon of old oil in the pan.

I did a test on that and on the NHC250 and you only get out about 4 oz more with the standard plug.

The 7 Tons are very different from the 5 and 2.5 tons. There is no comparison. For example, the 7 tons have the engine mounted high and several frame members are below it. The bottom of the engine is very well protected and it is obvious. In fact, it is all the protection that makes changing the oil difficult.

Other studies have shown that it is impossible to get all the oil out of the engine anyway. Even if you drain all the oil you can, there is still a lot in passages, lines, the pump, oil cooler, etc. Plus, you don't want to get all the oil out for obvious reasons.

EXCELLENT!

Good work!

I have used the Fumoto valves for many years on all my trucks and have never had a problem. They work great and won't open accidentally like many people think. The lever locks into a detent. I will be ordering one for the MTVR right now!

Thanks for the part number.

I also have the Fumoto on my M939 trucks also. They work great. Just a little slow on draining.

The HETs use a JIC cap on a parker quarter turn shut off valve.
