Re: Universal 5424 Diesel
Generally, it's a very good engine. Tough and long lasting, but a bit noisy and vibratory. It should have ample power for that Pearson.
Transmissions are available, rebuilt, or you can put in a ZF.
So far on my 5424, the Sherwood raw water pump has been lasting for 2 years / 200 hrs before the shaft seals fail. Watch for corrosion on the block under the pump, which indicates a leak. A slight leak is not too disastrous for a short while, until the corrosion blocks the hole in the pump that allows water to escape, then it starts getting forced into the engine oil!
You can get the parts to rebuild the Sherwood, or replace with an Oberdorfer. The Sherwood is nudging $400 for a replacement, the Oberdorfer around $200 right now. I've installed an Oberdorfer, and hoping for longer life. I also rebuilt the Sherwood to use as a spare.
The manual says to change the transmission oil every 100 hours, and it needs it. There isn't much oil quantity and it's under some heat stress.
Heat exchangers are easily available.
The main issue seems to be the exhaust manifold, hard to find.
All the engine parts common to the Kubota block are easily available. Just bought a starter motor for $80.
