I HAVE A IH240 UTILITY, AND WHEN IT'S IN IDLE AND WANT TO SHIFT IT IN GEAR - I PUT THE CLUTCH IN ALL THE WAY -(( BUT THE GEARS GRIND )) UNTIL IT SNAPS INTO GEAR -- NOW WHAT WOULD MAKE THAT HAPPEN, THE CLUTCH LOOKS REAL GOOD AS FAR A WEAR AND I PUT A NEW THROW-OUT BEARING IN IT ABOUT A YEAR AGO, BUT THE GEARS SURE DO GRIND -- ANY ONE HAVE A GOOD OPINION ON THIS ONE...

When I was running HYTRAN in the trans/rear end of a couple of my Farmalls, I noticed a lot more gear grinding, as you have described.
I made the switch to honest to goodness gear lube (the actual weight eludes me at the moment, it seems like it was 85 w90) and boy have those gears smoothed out. What are you running in yours?

I buy my stuff from my local oil company, and he uses EMBLEM products. It is a pretty standard gear lube, I know that. I put the Hytran in so that I would only have to keep one type of stuff on hand, but these tractors just don't seem to like it in the rear end/tranny. Good luck!

I did run a friends 140 that it seemed you had to double clutch to get the gears to line up. Even from neutral had to push the clutch, put slight pressure on the shifter toward gear you wanted, then let clutch out and push it in again and it would slip right on in.
If the lube doesn't solve your problem, maybe that will work.

No Clutch brake --- tried to adjust the free-play and that did not help either..

My David Brown does the same thing...I'm going to try the wd-40 trick as I don't see myself splitting this beast anytime soon.

I find that --- when I stop the tractor in gear - then when I start it --- it will go into gear easy -- but if I turn it off in Neutral - then when I start it - the Gears Grind.. so something is making the gears spin... darn...

The transmission input shaft is connected to the engine at two locations, the clutch and the pilot bearing. If either of them drag on the input shaft, it spins and gear grinding results.

Inadequate clutch release due to linkage adjustment or clutch wear is the most commonly blamed. But the pilot bearing is quite capable of causing it as well.

Thank you for your advise, I did replace the Pilot bearing a year ago, so it must be the linkage, now if I can only adjust that correctly -- I'd do good,, thanks again..

you mean it aint suppose to do that. What is it an automatic? In all seriousness, what happens if you hold the clutch pedal down for a little bit longer, you cant just push in the clutch and slap it into gear, there no syncronisers in these trannys.

I do hold the clutch pedal down for a while --- but it don't help --- so it must be out of adjustment, oh well --- now I have to figure out how to adjust the linkage... thanks for your input ...

my 560 did that, the linkage was getting worn, so i adjusted clutch and ta, now it shifts very good, i had set it by book but with worn linkage that dont work very good,my friends 806 gas had clutch trouble and the clutch spline had a little twist in it, but that shouldnt be your problem.

I have a test for you: with engine off, put the tractor in 1st gear and hold in the clutch. try to start it. IF THE STARTER ACTS LIKE IT TRIES TO MOVE THE TRACTOR EVEN WITH THE CLUTCH IN..... ....THEN I know EXACTLY what your problem is. The CLUTCH DISK IS NOT SLIDING ON THE SPLINED TRANNY SHAFT, which makes it stick to the flywheel. It is probably sticking on the shaft because the splines may be dirty, worn, and sticky.

You need to open the access hole, have someone hold in the clutch, and carefully aim some WD-40 on the transmission shaft where the splines meet the disk. keep doing this until you're sure its filtered in between the splines

I did your test --- and the tractor will not move when I start it in First Gear with the clutch in.. odd enough --- when I stop the tractor in any gear position and then --- start it --- the tractor will shift into gear with no problem...

But when I stop the tractor in Neutral -- and then start it --- I grind the gears...

Something is making the gears move some place. I tried to adjust the free-play -- but that didn't help...

Just guessing - perhaps the clutch is not adjusted properly? Perhaps the pilot bearing in the flywheel is bad? Too thin or too little oil in the transmission to arrest the gears/shafts shaft? Perhaps you are just too impatient? Perhaps supergrumpy is right? What engine revs are you using WHEN IT"S IN IDLE AND WANT TO SHIFT IT IN GEAR? BTW, please release the CAPS lock and stop SHOUTING). Perhaps the clutch driven plate was bent when re-assembling? Did it grind before you put in a new throw-out bearing? Is the pressure plate a diapragm, or coil spring, type?
Perhaps it like supergrumpy says....

I thought they did that from the factory, worse on real cold days
