Clutch Question

[NHmitch]

Hi,

I have my new clutch in my G154, and it has been working great, but it occasionally still grinds when I am completely stopped, have it out of gear and ideling, and then re-engage it, and put the tractor in gear. I am worried that it have be the gears, or I may just need to adjust it a bit more? It is a new clutch, throw out bearing, release bearing, and clutch plate. Any thoughts? Thanks!

Adjustment! If it were the gears, as in worn gears than I would guess it would still shift relatively nicely. Just a guess. keep adjusting to get it right. Good luck!!

How much time are you allowing the transmission to "spin down" before putting it in gear? When you push the clutch pedal in you need to wait a second or two before you can select a gear w/o grinding due to the intertia of the rotating parts in the gear case causing it to continue to spin.

Its kind of an interesting issue. It only happens when I let it idle in neutral, and I am off the tractor. I can see the PTO slowly turn when off the tractor when it is in neutral as well. When I drive, and stop to shift gears, it does not do it from gear to gear. Its only from neutral after it has been sitting for a few.

Did you replace the pilot bushing behind the flywheel in the end of the crankshaft?
If its worn it will let input shaft drag on the hole that goes through the flywheel
and may cause problems. But you do need to let input shaft to transmission
spin down before shifting into gear. If you are already in one gear and shifting
to another the input shaft is already stopped.

I didn't replace the pilot bearing because the tractor shop down the road that replaced the clutch told me that it was allright, but now I am very worried that it was not. I couldn't find one online, and he told me that he would look at it, but now I am wondering if the whole clutch job was a wasted effort because I didn't replace that bearing. I put in a new throw out bearing, clutch, and pressure plate. It only happens when I am off the tractor, and it is running in neutral for awhile. Its when I shift it back into gear. While this issue wreck my new clutch? Thanks for the diagram!

So I went out and adjusted the bolt under the tractor all the way, and now it does not seem to be doing grinding. It may have been an adjustment that I made after I got the tractor back? I was trying to adjust the clutch according to the service manual, but I may have adjusted it out too far?

It's probably all in the "adjustment" Mitch. Pilot bearings are rarely, if ever the issue. Unless it showed definate signs of coming apart (making metal) then you probably didn't need to replace it.

While I would agree that a pilot " bearing " should last a long time the TX1300F
has a pilot bushing and technically every time you push the clutch pedal in and stop
the tractor and engine is running the pilot bushing is spinning and the input
shaft is not, there will be some wear of bushing.

can i ask after it came back from the shop ...would you touch anything they worked on .. a good way to end up with a bill and no warranty and no way ever would you get any one to side your way on that one ...just saying

Thanks for the help! He said that the pilot bearing was still good, so it sounds like it should have been ok. The clutch seems to be working allright so far, and I think that it was an adjustment. When I sent it to the shop, it was with the understanding that they did not have the service manual, and I was supplying the clutch, so we discussed me fine tuning the adjustment according to the manual. He really didn't issue a warranty other than gross negligence. I used a digital caliper to attempt to follow the specifications that the manual called for, but I was adjusting old metal parts, and the clutch pedal arm where it attaches to the bolt under the tractor may be bent? I may have been adjusting it it incorrectly, but I am not 100% sure. The service manual says that the clutch pedal travel should be between 15-20mm at the top of the clutch, so I was adjusting it so the clutch engaged at about 18mm when I pushed the clutch pedal, but I am not 100% how I need to adjust the both under the clutch pedal that stops it from going all the way to the floor? Is the 15-20mm where it engages, or is it 15-20mm from when it engages until it reaches the floor? So far so good and hopefully it remains that way! Thanks again for all the help!

When I adjusted the clutch in my 1300 I set the free play to 15 to 20 mm
and then I checked the overall pedal travel which was off.
I adjusted the overall travel and then had to re adjust
the free play because I moved the stop bolt for overall
which did change the free play or gap between
throw out bearing and fingers on pressure plate.

Thanks so much for the diagrams and the help! That answered a lot of questions. I think that I need to go and recheck the adjustments that I made and see if they are allright. Can it cause damage if the stop bolt is adjusted too far out, and there is too much clutch pedal travel? Thanks again!
