Before I order any parts what updates or changes can or should I look for. The rotors in it now have 3 sets of rasp bars and the long solid fins on the rear. Seems to me that the later machines had some agitators on the rotors. Can I put those on my rotors and what other machines have the same internals as my TR 86? Need a right hand concave and extension. Use it mostly for soybeans but run corn now and then and a wee bit of barley each year. Thanks for any advice!

my dad upgraded the rotors in our old 86, but to what he cant remember. when we rebuilt them we took them to the plant to have them balanced. i have also done the same on our tr98. balance and timing are so important to this project. make 100% sure you understand the timing instructions in the manual. also, check your gearbox seals. if they so much as drip, go ahead and replace the seals. we did one during harvest when it was raining and it sucked. we also always replace the rotor bearings, this should be given.

by agitators, do you know what you mean? we put pegs in on our tr98 to help pull material through the machine. also, have you thought of having your concaves rebuilt? we usually do ours once ever 5-6 years. it really helps get stuff out of the head.

for sure check the seals. we have a gearbox out right now that had a chunk of wire wrapped around the seal and it wore thru the metal seal face. Dumped all the oil, but we lucked out and the bearings and gears are still good. Must have happened in just the last few acres we put through. Getting parts tomorrow, but for sure not from CNH. Most likely the bearing shop will have them in stock, while the NH dealer I can guarantee will not!

The newer machines have risers on the rotor that are welded on with plastic plugs to put the pegs in. I don't know if yours has the risers, but they can be ordered from new holland and put on yourself. Have a look see at the TR98 rotor diagram on the NH parts site and you'll see what I mean.
