95 U240 Engine Removal

August 25, 2016, 12:50:18 pm

My 95 u240 is now using more oil. The engine can be sleeved/bored to repair damage, but must be done in machine shop. How can the cat 3116 engine be remove from the MH for overhaul?

Pat,

Pat,

Some have found that the cylinders can be done in frame if memory serves me

The 3116 is a linered engine,you remove the old liners and put new ones in along with new pistons and rings,and a new head.
Have you priced a cat reman block?

If doing it yourself could probably rent a forklift.

Correct.

I have seen it done (boring and sleeving) at Mustang Caterpillar in Houston. An outside vendor did it in their shop-- that is all the vendor does for a living.

If your Caterpillar dealer is not familiar with it, call Mustang Caterpillar: (713) 861-0777.

No, the Caterpillar 3116, just like the 3126 is NOT a liner engine. It is a parent bore engine.

I agree with wolfe, the 3116 is a parent bore engine. I need help on getting the engine out of MH.

NO, only the head has to come off, assuming you can drop the pan to remove the rods/pistons. I observed it being done "in frame" at Mustang Caterpillar.

Yikes! Is my pic like yours with side radiator like ours? It won't come out the stern without major, major body removal + frame rail.
What happened to a usually bullet-proof engine? If it HAS to come out, from under looks like the only way. I'd be thinking, (unless you are a CAT mechanic) of finding another opinion, there are other reasons for oil consumption (bad turbo, for instance). What's the mileage and what oil & have oil changes (+ filters) been done on time? Does she smoke, what color? I if it is rings, tearing out the bed housing should work from above, and bearings can be done from below. I don't think ours has sleeves. Again, mileage and history of service would most certainly be of interest to we CAT 3116 owners.

I am all for opinions on non-factual subjects.

BUT, whether a particular engine is a parent bore or linered, is a FACT.

The 3116 is a parent bore engine. Yes, it can be bored and sleeved.

Contrary to popular belief, "an opinion expressed strongly enough (especially on the internet) does NOT overcome FACTS.

And as Mike asked, please give us particulars on what happened/caused the issue. Particularly after you tear into it to determine exactly what failed.

But, at 21+ years old, many times it is difficult to know its "care and feeding" since new. Was it ever severely overheated? Air filter neglected and ate some dust, etc. There are a number of causes of engine failure.

Hmmm......... put on lift and pull all accessory parts off sides of engine,then mounts and cross member and do a plop & drop out the bottom?? like a VW

The way to remove the engines on these RV's is to drop it out the bottom--unless you want to cut out cross members and slide it out the rear.

It's very simple, drop engine down to floor, and then lift the RV up using wheel lifts around it.

Yes find a pit drop engine down roll bus ahead and hoist the engine out.

Thanks for all the responses, and so quick. For the background of this issue/problem read the topic I started a year ago

Topic: Cat 3116 Excessive Oil Consumption by pthurman48.

I got it hot(temp and tranny alarms went off, engine temp was about 240) one time due to uphill grades, pulled over and let cool off and continued on to Myrtle Beach with no other problems.

an update to the last thread is

went to Ogden Utah on July 2, 2016 thru CO and WY, came home thru Moab,UT and Albuquerque,NM and home to Lufkin,TX. All the way I used a gallon a day(about 350-400 miles/day) same since problem started. Last 2 days coming home used 2 gallons a day of oil. The oil pressure also dropped off by about 8-10 lbs. I ran in 5th(2200 rpm@60mph) a lot of the time due to heating and or hills.

mine is a 95 with a large opening on rear, no bumper. you can read the last thread about

Topic: Cat 3116 Excessive Oil Consumption pthurman48

Still no smoke anytime, no leaks, runs good, just lower oil pressure and more consumption.

Had a customer put two liners in his in separate repairs.

In frame

What is the proper oil pressure for a 3126??...I am at 35psi

Re: 95 U240 Engine Removal

Reply #17 – August 25, 2016, 03:44:04 pm

Just checked for oil in the diesel, there was none in it, diesel was clear and slight green color. I also took the outlet(cool side) of the turbo off and checked for oil in turbo, it was clear and dry, no oil.

Can't read the link, but i'm still thinking turbo seals are leaking by, causing what appears to be a serious oil loss and gauge indicating low psi. With the rear exhausts we have, you might not even notice that she's smoking. Two gallons a day has "turbo" written all over it.

my 3116 oil pressure at 60mph@1900rpm running 6th gear, normal temps(182-195) is 39-40lbs.

My guy mentioned the oil control ring losing tension.

I can see the exhaust well, it will smoke(black) while running slow in higher gear with light throttle., but at any other time I don't even get that smoke. Oil smoke is white, I never get that.

I only hope that is the problem, I hate to think that it is broken and scoring the walls.

Same oil consumption issue. Cylinders were out of round also if memory serves me. Two liners installed

If compression ring(s) are bad and/or cylinder(s) are scored, you will have a LOT of blowby (1" ID hose on passenger's side below engine.

Do you have a lot of blow by?
