After a full inspection of the Yanmar 3TN75RJ diesel engine, I came to the conclusion that this engine had suffered from excess heat. Once I had a good look at all the parts I needed to figure out where I can find a rebuild kit and luckily there was an online supplier that had everything I needed.
Once the rebuild kit was on the way, I cleaned up all the parts and got everything ready for the machine shop. I always try and give the guys clean parts to start off with, so they do not have to do the cleaning for me!
Either way, they machined the cylinder block to fit brand new dry-sleeves. This way I will have each bore back to the original size (~3.000"). I could have gone oversize by 0.010" or 0.020", but then it would have been modified and I really like going back to the original standards.

The cylinder head received brand new valve seats and valve guides at the machine shop and these parts were also in the rebuild kit. This step does cost a fair bit more, so you can double-check to see if your original parts are still in good condition.

With all the machining done, I brought the parts back to the workshop and I was able to start the rebuild process. This video will show you every step from the engine block to the water pump and in the end, I'll have a complete Yanmar 3-cylinder diesel engine.
