Re: TRs fire prone?

I have a TR85, 95, & 97. I have trouble with the 95. Mainly around the turbo. Chaff will fall around it and start to smolder. I always carry water, because the extinguishers seem to spread it more. Usually happens atliest twice per year. Has not hit the ground yet.

Re: TRs fire prone?

Yes I remember this well.
Had that same thing on a 83 TR 95. NewHolland provided a piece of formed sheet metal that directed air from the fan under the turbo thereby keeping it clean, puzzle solved. I don't remember if that piece ever became standard or not but hopefully this lead will help you.

Ran a 83 TR 85 for 10 ten years, red & alsike clover dust used to build on the inside exhaust manifold and start to smolder, no fire just made sure to blow the engine area off several times during the day. As far as cereals and canola never a problem.

Re: TRs fire prone?

Its all got to do with keeping it clean. On TR combines there is space under the graintank, both by the engine and by the cab. On smaller frame models, TR75,85,86,87,88 ect the top of the rotor case is rounded over both rotors making an area that easily catches dust and chaff. I have seen alot of combines that the owners just never blow this dirt off of the machine. So take that situation and then just add dirt on the manifold. Once the manifold dirt starts up it will find its way right down the top of the rotor case toward the front of the machine. On small TR combines the fuel tank sits under the front of the grain tank and just behind the cab so once it hits the rubber fuel hose the machine will burn completely to salvage.
Large size TR combines have a flat surface to the top of the rorot case and are easier to clean but guys do not always clean them either.

Never heard of weak bearings at the rear of the rotors. The rear of the rotor is supported by the drive gearbox shaft not a bearing on the rotor itself. They do have a spherical bushing in the gearbox shaft that aligns the rotor and then a chain coupler that drives it on the gearbox shaft.

Re: TRs fire prone?

I had the hydraulic pump on my TR86 get a crack in the housing at the relief valve threads and it sprayed hydraulic fluid all over the engine. Pretty well soaked the exhaust manifold and turbo, why it didn't start a fire I don't know. I noticed the chopper drive belt alarm beeping a couple of times and got out to check it. As soon as I opened the cab door I smelled hyd fluid and saw smoke under the top engine cover, thought it was a goner. Sure makes a mess of things.

We had a hose blow (power steering) and it sprayed hydrolic fluid all over the manifold last year, and it never burned that time. I was pretty worried and i sat there for a half and hour watching it smoke

Re: TRs fire prone?

Have a TR96, 3208 motor. Had some close calls with fire. The worst area is around the turbo. When cleaning the rad,I always clean the turbo area too, (around the side of it where there is the motor housing that collects dust) with compressed air. Another spot is the left side of the combine where the straw chopper belt runs, there is a ledge that collects chaff right beside the belt (the 2 pulleys where you release the belt tension) and it created enough heat that it started to smoulder, luckey enough the trucker saw it . I then modified and cut out a small piece of steel so the chaff would just drop down and have more space between the belt and ledge.

Re: TRs fire prone?

Don,
Do you have a sketch/draft of such a piece of formed sheet metal. I own a TR 86, and had to put out fire a few times. With the global economic situation as it is at this very moment, I would rather do every thing possible to prevent any unnecessary losses.

Re: TRs fire prone?

Sorry, no I don't.
I talked to my parts guy at the NH shop, he's going to look it up, said call back in 1 hour.

Doesn't look like that's going to help.
I'll try and describe it for you.
A piece of tin I'd say 18" wide bolted under the right side hood support, angled 45 degrees down, large hole in the middle so air intake tube could go through the tin. a couple of tin straps supported the left side of the tin deflector, they bolted to the left side hood support. This than deflected air under the turbo and kept it clean.
25 years ago.
I hope this helps you.

Re: TRs fire prone?

I burnt a late model tr85 hydro to the ground in 400 yards. What i believe happened a hydro hose blew and the pump is inches from the inside exhaust manifold. It was totaled before i got out of the cab. Manifold, turbo fires i think are all due to being clean and not the combines make.
