The trailer will mearly be a dry safe place to house the generator and ancillary items. Also will make moving it easy.

Perkins/Cat/Kubota/Yanmar/Isuzu / 3TNV70 Questions
June 24, 2012, 08:23:20 PM
I have a 3TNV70 Yanmar engine that was salvaged from a utility vehicle. The PO ran gasoline thru it and wanted a new engine. So we replaced it with a new engine. No core on the old one and it was being scrapped. It got scrapped into the back of my pickup! I took it home, changed oil and fuel filters, disassembled and inspected injectors and glowplugs. All looked good. I removed the cylinder head and inspected the pistons and bores. All looked good. There was only 135 hr on the clock when removed. I temp mounted it to some wooden skid material for a test run. I gave it some fresh fuel and fired it up. My plan is to belt drive a 7k gen head for temp power. Eventually this will all be mounted in an enclosed trailer.
One concern I have is that this is a variable speed unit. My funding says I will have to go with a 2 bearing, 2 pole, 3600 rpm gen head. If I match the drive pulleys so that the engine turns at 2200 to 2400 rpm, will the engine, being a variable speed unit, pick up the load without dipping too low?

Howdy from NC.
Justa lil info on myself and my current project.
I retired from the Army after 20 yrs as a helicopter mechanic. Since then I have been working mostly on construction equipment. Had a short stint as a power generation tech for a global company but the travel became too intense. I now work for a John Deere dealership as a technician.
My current project involves a Yanmar 3tnv70 engine. My goal is to couple this up to a 7.5 to 10k gen head and provide backup power. I also have plans to belt drive an air compressor off of an electric clutch to use as needed. All this will be housed in an enclosed trailer. Exhaust fans will provide air exchange within the container while running. I am also thinking about having 8 6v batteries in the trailer hooked up in series/parrell to provide 24v. Then thru an invertor to provide silent a/c power when needed. Any thoughts or help as I go along with this project will be appreciated.
