I have built a small diesel generator but the mechanical governor does not seem to respond quick enough.I would like to build an electronic governor that will also have overspeed shutdown protection. I have built a couple of simple electronic controllers for my biogas projects from schematics but I am certainly not an electronics tech. The engine is from a refridgeration unit that was electroniclly controlled so their is a sensor over the flywheel for speed siginal to the controller. If anyone out their can help with this project it would be very much appreciated.

My 11 year-old 1000-hour 38 HP Yanmar 3JH2E Diesel on my 36 foot sailboat experienced crankshaft bearing failure. The center bearing disintegrated while the other two bearings remained in perfect condition. The circumstances were the prop shaft became entangled in lobster fishing gear during a passage through the Cape Cod Canal. In order to make any headway to keep control and get to a safe anchorage, I had to apply full emergency power to a heavily overloaded engine. The center crankshaft bearing failed, while the other two survived. Because the crankshaft was heavily scored, the engine was a total loss, and needed replacement. The insurance surveyor, claimed that this was a "mechanical failure due to latent defect" "or possibly faulty maintenance" and recommended that the claim be denied, despite clear evidence that the prop and shaft were entangled. I would like your opinion of the possibility that heavy lugging at high power settings caused he...

Description: Peugeot Sport 106 maxi flywheel. This is a homoligated flywheel for 106. Banned for Super 1600 but is fine to use under Group A6. This flywheel is very light and not suitable for gearboxes with long final drives. As you will struggle on touring stages (hill starts). However the pickup of the engine in the stage is chalk and cheese compared to the standard flywheel.

I believe in maximizing the rigidity of the block / transmission assembly. We had to reconfigure Honda's brace to fit properly with the Moroso oil pan. Details like this are important to building a long-lasting combination.

Lots of pieces fit into small spaces with this package. Note the sculpting to reduce flywheel mass and the small diameter of the pressure plate, disks and floaters. This set-up is extremely lightweight and capable of handling a lot of abuse, including shifts over 10K.

Note that the header primary pipes are configured to work with our raised port roofs. Oil heater? We'll make sure there's some separation here before installation. I'm also raising secondary pipes and collector about 1.5" for better in-vehicle ground clearance, which is important on the streets of Ft. Worth.

Don't be mislead by the picture, but it's imperative that the header (and intake) gaskets do not hang in the way of the flow. If you don't trim the gaskets, you're potentially sacrificing any possible gains from porting. We trim the gaskets to be approximately .050" larger all the way around the port. This gasket is situated ahead of the flange on the studs, producing the illusion that the openings are much larger than the ports.
