preventive maintenance on Cummins engines [Archive

Another soft point on the B's is the fuel cooler hoses The raw water pressure is greatest right after the pump and fuel cooler hoses have been known to blow I change mine annually As for the POS OEM Sherwood pump it will last 3-5 years if the impeller is changed annually then scrap em' for Tony's

How can this be

2017-9-5Case gasket is simple to replace if the shaft seals are leaking the pump should probably be rebuilt or a new one depending on hours condition I keep a replacement pump ready to go swap out the whole pump then service the removed pump at convenience My current pump has over 2000 hrs Impeller is about due has about 600 hrs _____

Source for Sherwood Water Pumps

2007-3-26Also there is/was shaft breakage issues on the 17000 series of Sherwood pumps but those are on the smaller Cummins B and C series engines Some leakage around the oil seals of Sherwood pumps seems to be a common issue after about 500 hours or so from the boatdiesel threads I'm not one for oil leaks though I hate oil leaks on anything

Trailer boat diesel inboard or petrol

2007-9-10The flush is basically a bucket under the sternleg with the flush mix and then a small bilge pump or similar to pump it up to the other side of the raw water pump (I remove a intercooler anode and screw in a hose fitting on my engines) Turn the bilge pump on and let it circulate through the engine for a few hours (I leave mine overnight if I can)

Sea Water Pumps Gone Bad

2011-1-3I know they are identical engines in this range and the +380~480 QSB's are same again except larger heat exchanger and turbo etc Maybe with the larger heat exchanger it needs a larger (therefore different) raw water pump Anybody know I have had t change the STB engine raw water pump twice now each after about 75hours because of leaking

Penta 2003T water leak

2014-12-31Apart from the pipe running from the gearbox to the water pumpraw water pump there are no other sources of water on that side of the engine (except maybe the head gasket) There is a multitude of connections on the other side which could leak Funny enough although many owners complain about water leaks I never had any on my 2003T during the five years I had it

The Hull Truth

A cheaper alternative to dripless shaft seals in the case's where the stuffing boxes get hot is to drill and tap the stuffing box assy install a small pipe to barbed fitting and run a cooling hose off the engine This injects enough water to cool the packing and keep it from failing prematurely

PSS Dripless Cummins 6bta Manual

2010-3-17Looking for feedback from those that have gone with a pss dripless Where did you hookup the water line? materials? Your thoughts? Pros and cons? Any pics? Any suggestions on a maintenance manual for a 94 6bta (unknown hours) with aftercooler? (I like the hard paper type with pictures ) Mostly for the periodic maintenance stuff

Is an Engine Survey Worth it?

ips problems

2011-12-31The new mechanic worked on the system for two days while we waited and replaced seals and gaskets on both drive trains and the oil pump on the port drive A sea trial revealed that the problem was fixed on the starboard side but it was determined conclusively that the re-built port transmission is defective and must be replaced

Perkins:6 354 Series

The raw water pump is flange mounted to the shaft on the engine fresh water pump The fresh water pump and the alternator are driven by the crankshaft pulley The belt tension has absolutely no effect on the raw water pump All the side load pressure from the belt is on the freshwater pump bearings not the raw water pump /i"

2010-6-6Two points are worth noting The system uses a raw water heat exchanger It is a very good idea to keep the discharge port as close to the waterline as possible (our installer put it about 2' off the waterline and the noise is unmistakable Second the raw water circulation pump is not self-priming

Rebuilding Sherwood Raw Water Pump

2016-3-5Rebuilding Sherwood Raw Water Pump It had 430 Hours on the Cummins QSB 5 9 engine but the water pump was failing as noted by Cummins service when PO had engine reprogrammed form 230 to 380 HP Evidently that is common for these Sherwood pumps

American Marine Ltd (Grand Banks)

The raw water pump is driven by the injection pump The single lower seal on the wet cylinder liners tend to fail leaking coolant into the crankcase Engines built prior to approximately April 1961 had no upper sealing ring for the cylinder liner and were fitted with a lower sealing ring only ( see Ford UK "Fixes" )
