C lectric, thank you for your response and providing a Great Point about going with higher pressure for safety margins...

Have what appears to be a faulty Oil Pressure switch for my engine Alarms. Can anyone please tell me what PSI, thread size, and NC/NO switch I need to purchase? I believe it is a NC (Normally closed) but I have no idea what the pressure to operate the switch should be. Alarms were working, but...

Ted, the alignment was done in the water. The engine remained on blocks while the transmission was out. Long story short, the original repair and to be fixed again, the transmission still leaked after the repair. After correcting the rear seal again (this time not removing the transmission...

Thanks Steve. So the repair was 1100 for transmission rebuild, and 5200 for labor (remove and install) 16 hours with 2 mechanics. The repair resulted in my boat being in worse shape than when I started. Several things needed to be fixed that should not have been necessary. Safety Neutral...

Twistedtree, The motor was lifted about 4 inches (measured from the oil pan bottom -before and after). The mechanics had to come back because the leak continued. They brought the technician that rebuilt the transmission, and he stated the alignment needs to be redone and the mechanics brought...

Thank you Lepke. I agree that it was excessive. It was and additional rework had to be done to include lowering the motor back to it's near original position.

The transmission is part of the engine mounting system.

Thanks for the great information. I talked to the actual person who rebuilt the transmission. He stated all the clutches and gears looked good. He did not replace any cast parts, just put in new clutches. After the install was complete, the repair still leaked. In fact when I started the...

My 1973 California Trawler (42LRC) had a rear shaft leak on the port velvet drive. The mechanic stated that the entire transmission would have to be replaced/rebuilt. 6K dollars later he stated that the shaft had to be aligned and the motor was adjusted to bring the rear up almost 8 inches and...

I have been searching everywhere so I am at a loss. I have taken my Perkins t6.354 heat exchanger apart to clean and inspect. The gaskets on the end caps had to be scoured off, I used a Scotch-Brite pad to remove all the material and the end cap is clean and shiny... I ordered new gaskets from...

Update to my post. I pulled the steering control out and had a local hydraulic mechanic look at it. He said that it was a bad seal located in the rear of the clevis pin. Replaced all three seals and no leaks...

I have seen several posts about this but nothing seems to fit my situation so looking for advice and help. My steering is leaking fluid at the cylinder. I have checked to see if it is running down from any of the hose connections, it is not. I checked to see if it is coming from the the piston...

I am about to do this same procedure on my two Perkins T6.354 motors. I love all the great tips, especially the vacuum trick to get all the pieces.

I installed solar on a 30 foot RV (lots of research prior to install). Ran Two 165 watt panels in series using 10 gage solar wire to a combining box (each panel fused with 10 amp fuse). Ran 6 Gage copper from combining box to MMPT controller. This prevented voltage loss (30 foot run). The MMPT...

Looking to replace the original oil sending units on my perkins TE 6.354 motors. I searched for replacement sending units and there are two different types. I do not really want to spend 100-200 dollars each for sending units. Can the originals be cleaned? Is there a substitute for the...

T6.354 (mgt) Air Filter instal Thanks everyone for the info. Sounds like, "If it aint broke, don't fix it". I will keep it the way it is with the stock screens.

Thank you for the information. I just replaced the clamps and exhaust elbows for both of my engines. They were both very corroded and one elbow had a leak. If you have any pics, I would deeply appreciate it. These motors are starting to cost me more than what I paid for the boat....

Looking for guidance. My mechanic suggested I install air filters on my Perkins T6.354 (MGT) motors. The only place I can see to install them is at the turbo inlet screens. Has anyone added air filters on their boat? How and what did you use? 1979 43 California Marshal. Thank you

Update: I have been tracing the wires and switches and they were for equipment no longer there: 2 electronic fuel pumps, fuel transfer pump, a removed water pump system, removed Radar system, and Autopilot system. Thank you everyone for all of your responses.

Since I have a motor boat (dingy) attached to my vessel, I call it a yacht.

Thank you everyone. It appears the starting issue is related to other mechanical issues (Fuel injector pump and possibly the atomizers. Having both of systems serviced. I do like the use of the hair dryer. Cheap, available and less maintenance. Once again thank you.

Would like to install a cold start device (heater/glow plug) to my 78 Perkins TE-6354M motor. Perkins Parts manual shows there is one available. Does anyone know where it is installed? Any special items needed other than the plug/device itself? Does it go on the round plug located on the aft...

Update: Sea water spraying near exhaust manifold Thank you everyone who provided assistance. Here is an update to my situation: Had a Diesel mechanic look at the motors and he confirmed it was the exhaust manifold and not to run the motor until fixed to prevent any further damage. I was able...

Trying to load pictures but not having much luck

I am trying to load some pictures of the issue, but am struggling. I did see the inside of the manifold has sever corrosion near the Valve Cover.
