Cummins 450hp Engine Overheats - Impeller Shaft Breaks

[3Mudbone1]

One of my co-workers forgot to open the seachest valve on a U.S.C.G. 41' aluminum boat with Cummins V-903M main propulsion engines and fried both Jabsco rubber impellers. He reenlisted and may have retired in the C.G. We had trouble picking up suction after that, probably because of pieces of rubber being in the passages. I went on to be an engineer in the best merchant marine unions in the world, then a west coast longshoreman refrigeration technician/ longshoreman.

Water pump failures are always a fun problem to have, around 200 degrees is nothing to worry about one of my diesels went to almost 300 and the hose going to the header tank exploded but the engine was fine (sucked up a plastic bag in the intake) One thing you should worry about though is all of those exposed hose clamp bands waiting to slice your arm open, you shoud get some Clamp-aid end guards on those.

@3Mudbone1 You're still an idiot.

[3Mudbone1]

@fnulnuable Are you fucking your mother and sucking your father off again! How sick! You should blow the shit out of you head!

@3Mudbone1 You forgot to put the "r" in your. You ruined your entire put down.

You keep returning to homosexuality when you are angry. Now you're adding incest. You have strange thoughts which are likely created from deep interest in the subjects. Pervert.

@3Mudbone1 o ok sorry

why not rebuild the pumps with new shafts, bearings and seals

that pump looks very similar to the vacuum pumps that are used on the 5.9l cummins i6 engines in dodge trucks.
