Clutch question ...

Recommended Posts

Al C.

On my SK-486 8-speed, half the time when I shift gears I need to release the clutch about a 1/4 inch in order to get the shifter to smoothly engage the gears.  It’s always been this way.  Transmission oil is 90W fresh, clean, and full.  Is this a nuance or the sign of a problem.  I never force the shift.

I'm not sure I can answer  what causes that but my cinnamon horse c-160 is  the same.

That is also an 8-speed. Transmission is in 1977 with unknown but low hours. Very crisp and tight transmission.

I would not say that that is a problem. I would say that it's just the nature of that beast.

 

We have driven several other tractors and most don't do it as often as this one needs to.

 

I notice the same thing with the trucks I drive on the road. You can get me 2 trucks that are supposedly identical and they will behave a little differently.

These are NOT synchro transmissions.  Every gear shift has to be made from FULL STOP.

I think Dave has the answer here --- they are NOT synchro tranneys.

 

Heh,If youre as old as some of old fa##ts then you will remember the term "yah gotta double clutch that dang thing, yah dummy!!" But, even that wont always work with these little horse trannys, just best to come to a complete stop.

I didn't even consider that @Al C. may be shifting while in motion.... What I refer to above happens at a DEAD STOP. I NEVER shift any of our tractors while moving.

My c-160 simply does not want to go into gear probably about a third of the time unless I let my clutch foot out just a little bit. Then it will slide in.

Thanks for everyone’s thoughts.  To clarify, the shifting issue I described is at a dead stop.  NEVER SHIFT WHILE MOVING, here.  It sounds like it is a nuance and nothing to be concerned about.

Even at a dead stop a non-synchro transmission can do this.  For that matter, a synchro trans can do it at a dead stop especially when the synchros are worn.  It just means the teeth on the slider aren't perfectly lined up.  When you release the clutch a little bit it turns the shaft just enough to line them up and allow the shift.  Lots of times you can try to put it in another gear first and it will jostle it around just enough to let you have the gear you want.

If you have the clutch idler set up so a tab on the pulley idler arm holds the belt from tuning when the pedal is down that will prevent the input pulley from turning so the gears can mesh. Let the pedal up enough that the belt brake lets go of the belt but not enough to engage the drive belt and see if it meshes better.

ALC. something you might try, is to verify that all your related linkage movement points  are lubricated and moving easily. those metal to metal areas tend to dry out and collect crud , possibly hindering your clutch action, just a thought , pete

One of my 312-8s is the same way except I need to lift it more like half way, not just a quarter inch in order for it to slide into gear. It's not every gear nor every time, I've gotten used to it. In the spring I'll look at adjustments, it's just too darn cold to be lying on the concrete for something seemingly minor.
