@jnaiken wonder if you have any insights as to the diaphragm replacement on the TDZ pump. My OM636 is revving up when going from gear to neutral. My diaphragm should arrive today. Any tips as to how to remove the old one and install the new one? How do you actually pull the thing out? Any...

Installed new end cups with new jubilee clips and hi temp silicone and the problem stopped

Thank you, Yes this is very helpful. I want to eliminate the option it’s a hole in the inner tubes. I’m in touch with Manfred. Just trying to understand exactly- the overflow stopped but not by tightening the hose clamps (which jubilees- on the end cups?) or extracting and installing the inner...

Did you fix the overflow issue? Check the end cups? Exchange the inner tubes in the heat exchanger? Did you run it for long with salt water and where did you let the overflow go?

I have exactly the same scenario with the filler neck breaking twice. My heat exchanger expels water while running at normal temperature. HowDid you fix it?

I used the dipstick but under the heavy roll after the squall the readings were so extreme I could not tell what the level is. However my knowledge with Diesel engines is so meager I thought I should see oil in the container below the cap.now I know all oil is in the sump and not in the container.

Yes, turns out it was a fuel block at the diesel tank outlet which is less than 2mm wide and it is just fw of the diesel faucet. I removed the extra oil. Cleared the fuel block - a piece of sticky gunk, cleared the filters and the lines I could remove. Primary was slightly dirty, secondary...

Mercedes OM 636. 4-4.3 liter oil

Today while sailing I started the engine during a squall and the engine quit after 15-20 minutes. Checked the oil by removing the cap. The whole oil container was empty. Filled in 4 liters oil. Still empty. No oil in the bilge or heat converter water or out of the exhaust. No smoke in the engine...

It gives resistance readings at the CPU end, as the RFU arm is moved. Not sure which numbers I am looking for at which angle. I am reluctant to open the thing up and possibky damage it. I removed the black arm , there's a center shaft and a plastic nut on it. How do you open it?

It’s possible the RFU is faulty, however when moving the wheel it does display full range of movement on the screen so this may indicate the sensor is working. But when going through the calibration settings it stops after the first hardover and indicates it’s at 15 degrees.

I can set it manually and tried 30, 35, 40 (quadrant arm degrees was measured and it actually 35&40 from center when on hard starboard and port respectively). These manual changes only made it not complete the whole movement range on the first center to hard starboard and it always stopped on...

reinstalled the RFU to be always parallel to the quadrant arm and dots are aligned when rudder is centered but the controller now displays 5 degrees to port when rudder is centered. Went through doc side settings and sea trial settings. Entered the rudder center point manually as well as rudder...

The controller of my Cetrek 730 autopilot is displaying the rudder is 10 degrees to port although it is midship. The autopilot never had any issues other than a fading LCD controller screen. I did drop the Rudder recently and reinstalled it but the Rudder Feedback Unit 930 809 arm was only...

Very sad to hear. Kevan surveyed my first boat in Lefkada, which was an identical model to his own boat. He did an amazing job, was super friendly and a pleasure to be with. I will remember him with great appreciation forever
