    Ford 3400 compression

    Good evening. Newbie with a 1974 Ford 3400 3-cyl diesel industrial tractor that won't start. I replaced the battery, fuel filter and fuel. Turns but doesn't catch even with ether. I suspect not enough compression. Front loader and backhoe are dug in, so pull starting is not an option. What...

The tractor came to me very uncared for and...

    Engine Compression

Last try I decided to adjust the valves and I was able to put a 8" wrench on one of the front pulley nuts and turn the crank fairly...
