Start by checking your oil filter to be sure it is clean. If good, then remove one of the valve covers and start it and watch to see if it is oiling. If not, then either you have a smashed oil delivery pipe or a bad oil pump or plugged sump pickup screen - the thimble sized screen with the rubber washer.

Some were equipped with optional electric cooling fans for slow operation in hot weather. If you have one of those and the fan is not working, then completely remove the fan and all the shrouds so cooling air gets to the engine, and it should be fine if you use synthetic oil and are not creeping around in 100 degree heat.
