froze turbo

[crown]

 found out that water got in the turbo it wont move
how can i free it up john

[NJT 5573]

Sounds like its toast. Did the water get in the bearings or the intake side? Bent shaft? Cracked housing? Did you try to turn it with your fingers from both sides togather? Was it out in the rain or what? What engine is it on?

its on a cummins 8.3 95 model water got in and sat
moter was not running so nothing bent can i put the
turbo in a bucket of old moter oil will that free it up ?

[Len Silva]

Even if you soaked it in penetrating oil and freed it up, I don't think I would trust it.  Turbos turn pretty fast and if it seizes up while you are driving, it may cause a lot more damage than the cost of a rebuild or replacement unit.

I would not chance it.

Crown, if the water only caused corrison interference between the wheels and the housing it is possible to spray some light penetrating oil on the wheels and housing and put a wrench on either of the shaft nuts and try to turn it.  You can also remove the housings and use some scotchbrite to clean up the housings.  As long as the binding is not in the bearing assembly You would probably be okay.  I used to overhaul turbo actually opened a shop for industrial turbo's for a aviation turbine company that thought it would be a money maker.  Learned more than i ever wanted to know.  YMMV,John

Either you buy a new bearing kit for it, or have it professionally rebuilt.  Considering turbos can spin over 10,000rpm, it'll be best to have it overhauled, rather risking it blow and possibly pass metal parts directly into your engine ($$$). Good Luck, TomC

Just to add one piece of info to help garner the most helpful advice, the engine and the turbo (and the rest of the motorhome) were fully submerged when the Monaco went into a freshwater lake.

I would guess that a frozen turbo is going to be among the least of your problems.  I would run it without the turbo until you are satisfied that everything else is OK.

If the turbocharger was submerged in water, most likely than not, the turbine wheel sealings rings are corroded/seized to the turbine wheel.   And the sealing rings are corroded/seized to the bearing housing seal bore.    

At idle this turbocharger is running about 9K RPM.   I would rebuild the Holset turbocharger (at least replace the center cartridge assy) and pull the cylinder head off the engine to inspect your cylinder/liners and pistons.   And pull the oil pan and inspect the bearings.

Was the engine running when it was submerged?  That would make a world of difference in it's condition.

hi the moter was not running when it rolled in to lake
the pan has been pulled and lookes like new the vavle
cover was pulled and all lookes good no signs of rust
all clean and well oiled the water went in through the
turbo and there is water on top of a few pistons but
overall looks like not to much damage moter has only
62.000 miles  as for the turbo water sat at the bottom
untill it dryed out thats where its stuck i think a berring
kit is a must any other thoughts on moter or turbo
thanks john

A couple of things come to mind......not sure what all you have checked so TIWAGOS (take it with a grain of salt

  Anything that has a breather on it may have let in water:
     Differential, transmission, some steering pumps.
     Then there is the air compressor.
      of coarse anything that is electrical could be compromised (if the circuit was hot at dunking time)
       alternator and even maybe the batteries.

    I have stripped some old cars that had been in a flood (yes a little diff than your present situation) but
    I was always so surprised how much silt was built up in what I would consider in-accessable ie 3 inches of
    silt inside the door etc.

Corwn ;

take the hot housing and cold side off of the turbo. If the center section will spin freely I would squirt oil in while turning it over, clean the housings and reinstall them and recheck. Tom said a turbo spins at over 10,000 rpm he is correct they turn at between 75,000 and 120,000 rpm when under load. Don't take a chance if you don't like the way it feels rebuild it.

Hope this helps

Don

 don how do you rebuild a turbo ? do they sell a kit ?
thanks john

Crown, do you still have the Holset tag on the turbocharger? 

Does it read HX40 or H1E??   If you can remove the turbine housing (hot side) determine if the turbine wheel is still frozen.   Look at the heat shield, if it is rusted to the bearing housing.  It might be better to order and purchase a new center section> NEW from a turbocharger company or a Cummins dealer.   The corrosion most likely will have pitted the seal area.   Installing a new service kit is a waste of monies.   The HX series cartridges are inexpensive compared to a new turbocharger.   

BTW if you give me your Engine CPL number I can tell you the turbocharger part numbers, or give me your Holset turbocharger number and I can give you the cartridge number.
