I agree with you too Clifford & Kevin.
Just say'n IF the engine needs replaced American Fleet Service is a good source.

If you get to the point of getting another engine, I'm with B_K.  Lots of good stuff about American Fleet.

OK, So the engine is hurt. We all agree on that. This is how you got here now.

As an independent diesel repair shop, I'm having a hard time believing this. Oil and filter and a botched fuel filter replacement isn't gonna need in inframe. if they can't start it now, How are they gonna start it after overhaul?

I have plenty of thoughts on this, I don't know your specific arrangement. Has anyone put a gauge on the secondary filter and read the fuel pressure? That would tell us if the blower/fuel pump is turning.

Do you have any type of emergency shutdown system/device. Do you have Jakes, Are they on?
Has anyone pulled a V/C and verified the injectors are in the fuel/run position?

Time for basics here, Sure, there's a lot of moving parts on a 92, But it'll run with a couple of weak holes.

Kevin -  the mechanic did all that.  Checked pressure, got under the valve covers and made sure the rack was operating properly and injectors were working correctly.  Key was on.  Jake's are off.  I wish one of you guys were here.  I'm only confirming cause I'm watching this mech go through all the stops.  I'm just not skilled enough to call him out on anything.

Waiting for a quote.

Waiting.

Agree with Clifford and Kevin.  It will run.  I would have them go around that electric priming pump-eliminate it- prime it conventionally, use ether if needed and fire it up.  Then I would get it outta there, either back to IPS in Billings or on to Hillsboro Diesel in Oregon.  Busted rings or scored walls, it's still gonna run, if you want to overhaul it, Hillsboro would be cheaper I believe than IPS, no sales tax either.  Two hard pulls going back to Billings, one short one over Lookout going west to Portland.  Hillsboro has a huge stock of serviceable used 2 stroke parts so you wouldn't get hooked on the high priced MTU parts.  JMO  Mail me if you need further help Sean.

What boomer said, Sean WILL IT RUN ON ETHER? If you can have someone press the starter while using judicious ether at the intake and it runs for a bit, that would tell volumes

Just catching up on where your at Sean, sorry to hear this. We'll be praying, not sure if we know anyone you could stay with there, I'll ask around. Craig

Sean said it won't run on ether (starting spray anyway, I don't think there is any ether in it any more).  If it won't even kick on ether, there might be more wrong with it than a couple of weak cylinders.  It got really hot, too, excessively hot to make the engine compartment door hot to touch.  One thing I didn't notice - is there any smoke when it is cranking?  No white smoke to me means no fuel is getting injected - or the injection event timing has been lost and it's not being injected during the compression stroke.  Clifford said maybe geartrain, and I wonder if it has a idler gear that is failing.

Let me say I hate to hear about your problems.  I have been there, done that on the road.  Cost me $7,000. to get a $1.00 part in my engine.  None of us want you to go through that.
I don't care for the 2 strokes, but they will most of the time get you home.  You didn't say if there was smoke out the exhaust when you tried to start the engine.  If you have smoke the engine should fire.  If there is no fuel smoke out the exhaust then there is another problem.  The Trailways shops used to change an engine in one shift.  No way it should take 40 hrs just to pull and replace.  Try to not have to make a fast decision, they can be wrong lots of times. 
Wishing you the best

Hi Sean

Sorry to hear of your problem.  That 6v92 will not run with a clogged exhaust.  Try opening the system someplace ahead of the muffler and give it a spin. 

[Scott & Heather]

Oh ok Brian. Then that complicates things....I wish we knew someone up that way that could take them in for a few weeks. If our spare bus were converted I would just mail you the keys Sean and have you fly out to Michigan and pick it up...but I assume you don't want to camp out in a steel tent

Hi Sean,

Very sorry to hear of your troubles.  Your family is in our prayers.

What was the actual pressure reading at the secondary filter? What about the suction reading at the primary filter? Have the filters been dropped and inspected? Maybe there's a defect?


You drove it in there, It's pretty hard to mess up the oil change, so since they botched the fuel filter replacement, I'm concentrating on that.

These aren't that tough to bleed. they'll catch on 1 or 2 then pickup the rest. Has he opened the return to see if there's good flow? Did someone remove the restrictor fitting during testing?
Have they plugged in the block heater?

How does it sound while cranking? I've had these start while barring over during tune-up.

I wish him the best it is a tough position to be in with a family and at the mercy of shop,but that engine should run if he didn't lose rear main bearing or a gear train,I have taken 2 cylinder out of play by jumping the injectors to get one to the shop a 4V92 is not much on power but it will run

[thomasinnv]

Yeah I smell something. It ran in, it should run out. They need to get it started again, and you need not to pay for their screwup.
