I have a 1999 freightliner with a dead Cat C12 engine. I am thinking of replacing the C12 with a 3406 or 3208. Can some experienced expert tell me if this will work, and if yes what extra parts will be needed to make it work? Please help. I guess the real question is, is 3406 A,B,C or D compatible with a C12? Are the configurations the same?

c12 only have 5 feet long; 3406 a,b,c,e have 6 feet long and if your fld is 112hood, the place is too short for a bigcat. you need big ratiator too. 3208 is too small in comparison with c12 it is beteer to fix your motor.you may look for it at any junk yard around for 8gs or your can put a 3176 b which is very cheap.

a,b,c, are mechanical engines. then 3406e is your electrical. there is the peek one that is in there between c and the e and it is part mechanical and part electical.

an old 3406A, by the time you got to 980c it should be a 63x serial number machine and a possible late 3406 70v or early 11n serial number. thats a difference you want, not a 3406a they had to update 3406a around the rocker brackets to cyl. head and block, by reaming out the spacer plate and putting in sleeve to direct the oil up the head bolt hole to the rocker brackets. the cyl. block does not have oil dowels in it, like the later blocks do. also most 3406a were pre-chombustion chambered engines, they could have been up-dated to direct injection but you would have to check that out.
if you were in ca. you would want to put in a c-15 retro-fit to met air board new spec. other wise it might not be able to work in some counties or cities.
to answer you question, 3406 engine are part for parts changable to a point. early blocks would not take the later fuel systems, rear housings changed number of bolts in the rear housing, but have used old housings on new engines and new housings on old,have to use gasket of the housing it matches to the cyl. block. at the front the 3406b change the front plate and front housing and gear train. earlier crankshaft differs from the new ones.
then there's the pistons and spray tubes, there have been so many changes I would hate to start, but there's straight rods, 6 degree, 9 degree tappered, they can not be mixed in the same engine. different weights.
if you do your home work, you can build or swop engines.

Need help! Our Fire Dept was given a Cat 3208 / Modification # 9E0687-03 Arrangement # 9N0634. We know absolutely nothing about this engine; what it can be used for, what it's worth, only that it was donated. Would like to get specifics on it so we can sell/trade towards a badly needed brush truck. ANY guidance/info would be greatly appreciated.

Have a 1993 Peterbilt 379. Any suggestions out there on what to do with the CAT 3406B engine to bring it up to the new C.A.R.B and EPA Codes that take effect 2010? What is the least expensive route?

this truck was overheated - low on water due to hole in radiator- found water in oil, changed oil,pressure tested cooling system and it will hold pressure for a couple of days. Engine will run for a week in the yard and not get water in oil but as soon as I take it on the road the water goes back in the oil. Can anyone help with what I should look at first or how to determine where the leak is?????

93 f-liner i suspect your waterpump may be leaking oil to your system. if the system was dry while using it, the carbon seal on the waterpump shaft may have damaged so badly it leaks internally. check the indicator hole on the waterpump housing. once the hole is open the possible water leak from the carbon seal should drain from the hole. if the hole is not open the leaking water breaches the outer lip seal causing water to leak into the front housing. the carbon seal may not leak once idling the engine. once the engine runs at higher rpm the pressure inside the pump impeller housing inceases causing a possible leak.

1993 Peterbilt 379 the only option is to install a DPF (diesel particulate filter). there's no other way i believe. and since it's a mechanical engine there's virtually no way to do it otherwise.
