Well, check the cage for wear, helicals, concave and bars, feed chains. Other usual items, but the cage area would be where I would look it over good as unless it has been "hyperized" the cage will have had some pressure on it in a couple places, mainly just to the left of the concave. You are right, only one more year of the N"s but the P1 R's are pretty similar in the processor area.

Crawl under the machine and check the bottom of the feederhouse floor. They have a tendency to wear a hole there and let crop material fall through and build up on the hydro which gets hot and starts to burn which can really make a big melted, smokey mess of your pretty machine.

Besides the cage and feed chains the obvious thing to look carefully at is the motor. If the motor has not as least been under hauled at nearly 20 years of use--be careful. Motor problems probably kill more of these machines than any other problem.

Cage, accelerator rolls, concave and helicals are where I would start. If that old girl still has the reverse bars in it the cage will be thin where the concave and cage meet. Motors were slowed down by then and were not as prone to putting holes in the block as were the early ones. Crawl under machine and check the separator clutch pins for wear as well as the bushings on the clutch plates. While under there look at the feeder house floor, hydro belt and idler and feeder house drive belt. Check the heads on the bolts on the hydro pulley for wear as the hydro belt tension spring hits the pulley bolt heads if not adjusted properly. Check the bin loading auger for free play. There is a universal joint at the pivot that wears out (easy fix). Check the bin floor for wear and the unloading auger at the pivot collar door for wear. Check to see if the collar balls have been lubed.
