The sender in the middle of the engine with two terminals is oil pressure. Behind the alternator with two terminals is alternator energizing switch and single terminal is oil alarm switch.

Colly, Yes the engine block is identical, but the bolt on supports may be different dimensions so just swap them. Also the trans to flywheel housing are identical, but on some engines a 200#...

Hi, Sorry to say this coupling is no longer available. However you may find the pump side coupling on ebay It was a browning CHFS2X5/8 A local machine shop can make you a nylon centerpiece. For the...

Joe, Transmission Marine 800-462-8848 ext.427 has parts for your trans.

Joe, I believe you have turned the lock ring in too far. Back it off two notches and try again.

Hi, Need more info. Why was head removed? Overheated? Is the oil pan off? How do you know water goes up and down? When pressurized can you turn it 4 or more times with out locking up?

Hi Scott Free, no , it will come off fairly easy.

Hi Scott Free, Did you put #2 permatex or rtv on the splines and under the coupling nut?? If not it will leak. Also if the seal riding surface on the coupling is worn you should replace it....

Thanks for the info. doubtful that this is an injection pump problem. I have seen similar problems when fuel tank vent lines droop down over time and if the tanks are overfilled the vent lines fill...

Hi, Can you tell me the year of your engine ? In the meantime i would try running out of a five gallon container of clean fuel connected to the lift pump to see what happens.

Hi Jim, It would be best to change gauges and senders at the same time. Check with American diesel, they may still have some original VDO's or equivalent. 804-435-3107

Hi. The oil sample should tell you whats going on, but at 3000 hrs it's most likely cam and crank bearings. are you using a Fram PH8A oil filter or equiv.? If you do replace bearings, change oil...

George, assuming everything was checked ,the engine should be good for another 6000 hours. Have the head bolts torqued after 20 hours then normal maintenance.

Hardin 45, give me any casting numbers you see on the head and block and i will tell you what you have.

Hi Ematty, on the front top of your exhaust manifold should be an air bleed petcock. always bleed the air out at this point when filling the expansion tank. a larger tank should not be necessary and...

Hi hanno, that gear was heated and pressed on at the factory and trying to remove it should be done by a machine shop. Unless the engine was rebuilt there is no way for the gears to change. Timing...

Hi, most likely a worn shaft seal in the pump.

Harry, Without seeing the piston it's a tough call, however pitting can cause hot spots and preignition ending in destruction of engine. you will probably find pitted valves in that cylinder also....

Rubber Duck, sounds like you need to have those injectors rebuilt. You may have a few that are not seating properly and in some cases let compression leak back causing air in fuel system.
