NWC Ohio | Pull the filler plates out of cylinder if not already done. Won’t need them for anything except maybe high moisture corn.
If you have a TitanII series, back your engine speed down to just above when the rpm tach starts to flash. This will help keep all the rest of the shaker system in better condition if it still has the original (faster) Titan II drive gear. My 6620 TII I was able to swap to a different sized belt pulley on clean grain elevator tensioner shaft and was good to go.
Make sure you regularly grease the grease zerk on the end of the main power shaft. You will have to get under seat to get to it as it’s behind a main pulley on the main shaft.
Read the OM and understand how to properly grease the variable drive cylinder sheaves. Make sure you keep it properly greased as well. Keep the primary counter shaft greased as well, and keep an eye on those bearings.
Keep rotating air screen and radiators clean. Make sure you keep the door seal in good condition, especially the seal around the duct that sucks air to keep the rotary air screen clean.
LED replacement lights from Larsen lights or Tiger lights work fine in the old housing. LED will have more light bounce back off the dust if that bothers you. Halogen lights don’t do this as much. At least in my perception. LEDs are nice as low amp draw. I still prefer Hella brand Halogen lights. But I have a mixture on my combine. Can get some whole LED light assembly and just swap out the whole original light housing assemblies as well. If you do a lot of roading at night, keep your light choice (dimmable road lights) in mind so you don’t blind oncoming traffic.
