Been awhile since I have posted. Just had my C603 crawler engine overhauled. It spun a rod bearing in the field. 3 cylinder air-cooled diesel, weighs about 850 lbs at least. And its finally ready to be reinstalled. It was a bear to remove it since the pilot bearing stuck to the spline shaft. I plan to use a pallet jack to support the engine on the way back in since my engine hoist legs do not fit between the tracks. This is the first time for me to reinstall an engine in any tractor. Any sage advice or tips regarding how best to do this? What should I watch out for? Thanks
