question ?

[TheShagler]

I was driving my truck arownd and all of a suddin it engine disingaged. It was still running but when I hit the gas it didnt move. I let it sit there alittle while and tryied it again. why did that happen? does it have something to do with the slipper clutch and if so what is a sliipper clutch.

The slipper clutch is there to protect the transmission of the vehicle. It allows the spur gear to "slip" under conditions where the engine overtorques the input shaft to the tranny.

As for why your problem happened...could be the slipper clutch, could be you stripped your spur gear, burned up your clutch shoes, or any of a number of problems. Did the truck move again, after you let it rest?

Another forum etiquette issue, try and be as complete in your description of the problem in the initial posting. Saves us from having to play "20 Questions" with you to get to the bottom of the problem.

what didnt move, the truck or the engine when you gave it gas? (was the engine reving when you hit the gas? )

I just had a problem just like that and it was a stripped spur gear, It was four dollars and about two hours work.

I've heard this from other boards. The truck will run and then you give it gas and nothing... If you let it sit there and idle and then hit the gas, the truck goes again. I'd adjust the slipper clutch just to make sure and if that doesn't work, check your clutch shoes. Haven't had the problem occur on mine, but have heard several complaints about it.

yea thats what happend. I let it sit and then I hit the gas and it moved again.

You might check your clutch shoes within the clutch bell. When they get too hot they tend to get slick. They might not be engaging properly. When your truck does this again, check to see if the clutch bell moves when you give the engine gas. If it does, then your shoes might be fine. BTW the clutch bell is that gear on the end of your engine's shaft.

If the clutch bell is moving, then odds are the slipper clutch is doing it's job, too well. You may need to tighten down the slipper clutch nut. This will tighten things up on the spur gear, and allow it to engage properly even if the engine starts to overtorque the input shaft.

Let us know how things work out.

how do you tighten up the slipper clutch

 

[SkyMaxx]

Look at the spur gear. The nut that is near the gas tank on the input shaft to the tranny (the shaft that the spur gear is on) is the means to tightening the slipper clutch. Notice the spring just behind the nut? That is the mechanism that places additional force on the slipper clutch. Tighten the nut a turn and see how the truck handles it. Then go a little more until you do not see the same problems again.

Watch out how tight you go. If you tighten it all the way or too much, you effectively remove the slipper clutch from the drive train. This means that the engine is driving the input shaft to the tranny almost directly (it is geared down but...) This can put undo stress on the tranny and in extreme cases strip gears both external (spur) and internal to the casing.

Hope this helps.
