Having just purchased this tr98 I want to ask a few ?'s
It is equipped with 20/42 duals and maurer large bin ext with the tip top ext. Have a 12 row cornhead I would like to run on it. Will it be too much of a load on the drives. Any other things to watch for on NH's? I have been with red for 23 years till now. It has a bubble hyd auger for bin fill. Will I need any extra counterweights?
Thanks,
CC

No experience with that amount of weight on a TR but I am not aware of final drive issues like the earlier IH's. Hopefully you have the heavy single speed feederdrive because I don't think the variable speed drive would be up to running a 12 row head. Does your machine have the heavy bubbleup drive? Later 98's do and older ones may have been retrofitted. Not sure what the capacity of the clean grain elevator is but in good corn I think you will hit the capacity limit. TR99 has a slightly larger elevator but not really sure how much the capacity increased.

I had a 12 row on an 88 and an 89. You shouldn't have any trouble.

Looking for owners of TR98 combines that have had fires and what started them

Had a little bit of smoldering from pea dust. Was running in hot weather and found that opening the top of the engine compartment helped to keep cool depending on what direction we were running (if the wind is at the back and blowing across the machine from left to right the fan seems to be counteracted and won't pull as much air through the rad). Opening the top lets the air escape. But also lets pea dust sift across the exhaust manifold. Then it drops down onto the triangular brace near the shaker system on the left hand side (near the chopper drive pulley). If you run with that side panel in place, the air swirls in there and also doesn't allow for you to see a pile smoldering.

Didn't burn the machine down but smelled it before it even got flames. However, we always run with that panel open (or most of the others are off) and watch that location. That seems to be a possible hot spot. '

Also, when I rebuilt a rotor gearbox I left the triangular sheet metal covers off the sides where you can get at the gearboxes. The engine fan seems to be able to sweep that area clean now without those obstructions, making for less buildup near the gearboxes.

We had ours on fire once the o-rings on the oil cooler started to leak and the are under the exhaust manifold dust and oil built up and finally it started to burn so now every other day we go in the hopper and open the door in there and check it out. We were lucky we smelled it in time and got it out the Hutterites did not and burnt the combine down.

Some of the TR fires can be attributed to the failure of a snap ring in the torque sensing pulley on the rotor drive. When this fails the pulley hub rubs on the frame of the machine and causes the failure of the oil seal in the right hand rotor gearbox which nows drips oil on red hot metal and you get a nice fire going very quickly. If you look at used TR's many have had at least slight damage in this area. New Holland should have updated this problem area but never did. There are several different aftermarket fixes available and any decent machine shop could come up with a permanent repair.

Clean grain system will be the biggest problem, you need to sure you have the newer bubble-up gearbox. You might also want to look at extending the bubble-up auger. You will want the third cylinder for the header lift. The 12 row will limit your speed. Most of the few fire issues on New Hollands are in the exhaust manifold/injector return lines (plastic). The current machines come with an air compressor to blow said areas off daily.

had dust build up on ex manifold and catch on fire. second time it happened it burned up machine!!! tr99 has a dust cover over man that should help. we run a air reel that puts a lot of dust in the air which makes it worse.

TR98 very durable machine, we ran one for 9yrs with no major issues.
The circlip behind the rotor variator is an issue as wtw said earlier. When it breaks it lets the pully rub against the frame. We replaced ours as a matter of course a few years ago.
We also had dust build under the exhaust manifold, we cleaned it daily and never had an issue. You have to lean right over the engine and stick your head down behind to see it, it can't be done when engine is hot.
Overall an excellent machine.

Any counterweight needed ?
Have the above features already.

Do tell. Aftermarket parts can be found where for the rotor drive retrofit?

Atom Jet has done quite a few rotor drive updates. Basically their update converts the snap ring arrangement to a system similar to a valve and keeper arrangement. I could not find it listed on their website but I have talked to them about it. http://www.atomjet.com/2009-09-24-13-13-08
Penno's Machining has also repaired quite a few rotor drives. Their fix basically is to use a heavier ring which they tack weld in place. My present combine has this on it and has been trouble free. Contact info only: http://yp.blogflux.com/directory/ca/mani....honeyman-ave-n/
On my previous TR I had a local machine shop modify the rotor drive by machining the snap ring groove and splines off of the hub and then cutting thread on it. They made a large nut to match the hub and also made provision for a locking setscrew. Was a very economic fix and worry free. I will get done this done on my present machine when I need to disassemble the hub. Any competent machine shop could do this work.

We had ours done and they just widen the snap ring groove and put two thicker ones in.
