Cummins Engine Replacement: has anyone done this?
« on: September 29, 2015, 07:54:36 AM »
It's a long story, but cliffnote version is 1997 Discovery was brought into Coach Care Service Center where they performed engine diagnostics per our request to replace a fuel pump.  After $860 of engine diagnostics, they confirmed we needed  a fuel pump.  My husband decided that he would make the repair himself, paid the bill and left. 8.5 miles down the road the engine exploded!  Destroyed!  Needs to be replaced.  Coach Care will take no responsibility stating that it was inevitable.  We argue that if the engine was in such catastrophic state why is it not stated on the service order, why not tell us?  So now we are left with either replacing the engine or scrapping the motorhome.  We are devastated.

Has anyone every had an engine replaced?  If so, how much did it cost (ballpark is fine).  We are getting outrageous quotes from the Coach Care Center that did the original engine diagnostic work.  $18K for the labor and some misc. parts as we have located a diesel engine.

The motorhome is not driveable so it's just sitting on the Coach Care lot for 3 months.   HELP!!!!!

Sorry to hear about your problem.

Not sure any of us can give considered opinions on what they should have/should not have foreseen-- certainly not without a lot more facts.

Please tell us exactly what the root cause of the "engine exploded" was and what parts are damaged.

Hi , cannot understand how a engine exploded via working on a fuel pump mainly on a non
Electrontic Engine. First of all what failed ( injection pump, connecting rod go through side of
engine block or what. ) there has been a tech bulletin on the 1997 cummins engine pertaining,
dowel pin in front timing cover that is located next to injection pump gear. This dowel pin comes
Loose and falls into the gear train in timing cover. This bulletin was for just the 1997 engines
only. Cummins has a repair fix for this dowel pin coming loose long time ago but many people
Did not recieve information. My suggestion buy a used takeout engine and put in engine in
Motorhome and re power with a used take out cat 3126 engine. The cause of problem did not
have anything again with checking injection pump. Dave Atherton Retired Cat mechanic

Engine Failure, Cummins Engine. The $ 18,000. Cost is in line or below what repair or replacement
would be. You are correct in one sense, weight what is your motorhome worth in running condition
with another engine. Get what you can for present Motorhome way it sets and take money for
repair and apply it to another Motorhome. We had a case last spring party lost engine and decided
to repair engine. $ 30,000. Later has a rebuilt engine on a Motorhome worth $ 15,000 to 16,000.
A person can find good running takeout engines for $ 5,500. To 6,500 the labor to change out
In Motorhome is where all the cost is. Dave Atherton Retired Cat Mechanic

I did a quick search and found many running take outs for under $3000.00 and a place selling Reman long blocks for $3500.00.

It aggravates me when shops quote such outrages high prices.
Hope the OP comes back for a progress report.

Wildebill, this job is not as bad as it may seem. You're correct there are good running takeout
Engines out there and as you indicated starting around $ 3,000. price range. Myself would go
little higher like I have Posted above and engine would be dyno. When you get all done with
Remove and install you will have around $ 10,000 involved. With rear mounted radiator setup
We would very neat cut opening in the bottom of rear cap. Than build and bolt a extension to
frame rails after you remove radiator. Make a cradle for floor jack ( need 2 ). Remove engine
and  transmission as one unit sliding ahead on extended frame rails. Note: it is a lot easer to
Remove an install transmission and engine parts out in the open. We have also raised up coach
and dropped engine out from below. Personally would not go this way too much extra safety
involved. Going back to cost depending what labor rate for two people you should plan for $ 5,000.

$10,000 is a lot cheaper than $30,000 that you were throwing around. I think with a little shopping the $10,000 could be shaved quite a bit.

Wildebill, you are correct but allow extra money to send radiator out and have boiled
( in most cases limed up inside.) we again extended the frame rails and cradled engine
so it would not tip, than used come along to inch engine to outside rolling on 2 floor jacks.
Going back in same used come along and pulled in place as one unit. This will really go
fast once new engine is dressed and in place. There is enough money where you can
really do a first class job. Just a little welder fab work to start. We taken the fiber glass
End cap we cut out very neat and made plates where both saw cuts , used two pieces of
Crome and bolted everything back in place. Dave Atherton Retired Cat mechanic

Does anyone know the final verdict?
