I've got an Allis 160 with about 15 hours on an engine rebuild. How hard or gently should I be running that engine? I plan on blowing snow with it this winter.

thanks

If it runs and sounds OK and has good oil pressure it should be ready to work.

Change the oil and filter if you have not yet done so since the rebuild.

Actually a good steady load would be good for it to seat the rings in. I usually try not to let a new rebuilt engine idle too long or lug it too hard for the first 100 hours or so.

Have had a few tractors that where rebuilt for collector fellows and just paraded. They never would run them hard enough to seat the rings. Had two that would burn oil. So I now run all of my rebuilt engines on the Dyno for a few hours at half rated hp and then a full hour at full hp.
Have not had any problems since I started doing this. Plus I now can re-torque the head before the guy takes them home.

Have a good family friend that lives in northern Kentucky. He says that they started seeing this issue when guys started to feed round bales of hay. Before that it was common to overhaul a tractor in the winter months. Then the first work to be done in the spring was heavy field work so everything was fine. Then guys started to use round bales. So their tractors where ran at light load in cold weather. So the rings many times would never seat.

It had all new fluids and filters with the rebuild. After the winter, it'll have 25-40 hours, and I'll change the oil and filter then.

thanks for the input

If I'm reading that right, the rebuilt engine had new filters put on it before it was fired and you haven't changed them since. If that's the case you should really change the oil and filter again asap. This will insure that any remaining machining debris, dirt, assembly lube, etc, is removed from the engine before you put more hours on it.
As far as a break-in, you NEED to load the engine to properly seat the rings. Don't be afraid to work it hard, just don't overload it for long periods. Try to keep idling and light load running to a minimum for the next 50-100 hours.

It's grown awfully cold in recent days, but on days off work I'll run it good and warm and then change the oil and filter.
