Cat 3406B crankshaft seal

yes it can but it requires special tooling. i suggest you contact your local dealer for the tools or techinal drawings so that you can manufacture such tools.  (Apr 21, 2011 | post #2)

g3520c major overhauling

perhaps using 3516 or 18 kits... and order the head, manifold & service hatch gaskets that you need to cover the rest. yeah its a pain in the ass that cat doesn't offer kits for the less common engines. in such cases i have ordered a kit for the same engine family, the main gaskets and the majority of the rest fits all in the family.  (Apr 4, 2011 | post #2)

Cat C13 Crankcase pressurized

excessive crankcase pressure is a symptom of: - a plugged or clogged crankcase breather. - a restriction on the breather hose or piping. - if equipped, a major failure in the air compressor. - excessive cylinder blowby caused by broken rings, overly worn cylinder, or a piston failure. start by checking the breather and the breather hose or piping for restrictions. if no air compressor is attached or the crankcase pressure buildup stops once you disable the compressor, it is most likely you need an engine overhaul. ask for more info  (Feb 16, 2011 | post #2)

cat 3126

how any hours does it have? is the engine under signicant loads normally or does it run most of the time at low loads? does the blowby gas stream coming from your blowby pipe pulsate or is it constant?  (Sep 25, 2010 | post #2)

Queries on C9 caterpillar engine

yes the water found in your inlet piping between the core and engine inlet is indeed condensed moisture from the surrounding atmospheric humidity. the normal range for inlet manifold measured air temperature is 10 DegC to 50DegC with electronic Cat engines, there are few exceptions though. if youre normally running on 30 DegC (86DegF) it means you have pretty much sized your aftercooler correcly. the collection of condensed water is unavoidable and does not affect engine performance, attleast not in the worse direction.  (Sep 25, 2010 | post #2)

cat 3406 engine

all mechanical 3406 engines have the same displacement which is 14633cc (893 cu in). marketed displacement is 14.6 liters.  (Sep 4, 2010 | post #2)

High exhaust gas temps cat 3406, what could be the reason

the conditions that elevate combustion temperature (starting from the most likely ones) are: - collapsed or clogged air filter(s) or air inlet piping/hosing. - incorrect fuel injection timing. - engine runs under extreme loads. - clogged or failed aftercooler core. - fuel injection modifications, such as adjustments for higher power that exceed the engine nominal power range. - a cylinder failure. ask for more info.  (Sep 1, 2010 | post #2)

rear oil seal on a 3406e engine

both the front and rear crankchaft seals are meant to be installed with the inner ring, which indeed is a wear sleeve protecting the crankshaft from grooving. if someone has gone and replaced only the seal itsel that means the person cannot read the instruction that come along with the package of the new seal group. the seals that are available now are universally fit for all 3400-family cat engines and do not have a separatable wear sleeve, thus making it even more clear that the seal group should only be installed as a unit, not separately. the current seal is a hydrodynamic seal and does not function with the older generation wear sleeve, especially if the old sleeve has a worn groove from the old lip-type seal. also it is nearly impossible to remove the wear sleeve from these current seals without destroying the hydrodynamic seal itself. these seals are meant to be installed with special tooling and cannot be installed separately or onto a housing thats off the engine. also removing the wear sleeve requires special tooling. the rear seal should be blue or purple coloured and must have a counter-clockwise rotation cymbol, hence the engine rotation is counter-clockwise. the front seal should be green coloured and must have a clockwise rotation cymbol. if these are mixed they will definately leak as the hydrodynamic function will be inverted if the shaft rotates in the wrong direction. ask for more info.  (Aug 8, 2010 | post #2)

cat c12

the most likely cause would be a failed fuel injector o-ring. remove the valve covers and check is there are any drainmarks around any of the injectors. if not you should start the engine snd carefully inspect the injectors for fuel leaks. remember: once the engine is operating the main fuel gallery has a fuel pressure of approx 500kpa (72psi) and if leaks are presesnt they might cause personal injuries.  (Jul 27, 2010 | post #2)

3208 oil blowing out exhaust at idle

turbocharged or naturally aspirated? it could be a worn turbo shaft seal, broken piston rings (or worn piston ring grooves), or the engine actual hours are way greater than the seller promised.  (Jul 11, 2010 | post #2)

cat c12 misfires

sounds like air in fuel. or it could be an issue with the timing sensory circuit fex. a failed secondary speed/timing sensor. does the engine dashligh indicate any faults?  (Jul 11, 2010 | post #2)

Cat 3204 di engine

you will need the original cat part number for the nozzles so that you can start searching for aftermarket ones. give me the engine serial number and i'll give you the part number.  (Jul 11, 2010 | post #5)
