Seating new rings

Put it on a chassis dynamometer. Run at part load and speed for 30 minutes, then full load and rated speed for 4 hours. See photo of rebuilt D311 in No. 212 Grader.

Mark,
If you don't have a place to work it right now, I would say just run it enough to know it's going to stay together and has good oil pressure etc as well as making sure the injectors, valves etc are working properly and then let it sit until you get a chance to work it properly.

The chasis dyno is cool if you have access to one.

Hi Mark Reindeau
I note with interest your query re how you cpuld run in an overhauled engine.

A few years ago I overhauled a six cylinder "Case" diesel, without any work drawbar for the tractor, the method used was as follows - firstly do not allow the engine to idle at low revs, if you have accsess to a good road, just go down the road in top gear, then just constantly open and close the throttle. In doing this upon opening the throttle the engine is put under full load - then upon reaching full revs immediately close the throttle again which will flood the cyliners with oil.when you close the throttle each ime allow the engine to get down to idle speed, them imediately open the throttle fully again. and I did this with my tractor over a distance of about 15 miles, and the engine does not use a drop of oil, runs and starts perfectly.

Just a suggestion for what it is worth.
