If you can get if to rev up then it sounds like a secondary or belt issue. Is it the correct belt? if it is too long it will not pull in to the clutches correctly which would load the engine down. Or your sheaves are not moving freely to allow the belt to pull in.

Put it up on a stand, open hood, open throttle up while watching belt... It sound be running at top of primary and bottom of secondary at speed. On a stand it should snap right into the sheaves.

I will try to make it work on a stand and see. I am going to take it to a friends house and we are going to go through the clutches. He has done quite a few and we are going to get it running right. Thanks for the help guys I will let you all know how it turns out.

mine will spin up 7000+ and stay there with the throttle wide open. If you want to check your secondary clutch... just cleaning it and making sure it moves freely may help.

With the help of guys here I have learned the secondary is easy to work with. one bolt holds it on the jack shaft. If your shaft is as lubed as it should be the secondary should slide off very easy. once it is off you will have something like this...

You may have some dust covers on yours making it look a little smoother.
remove the snap ring and washer...


slide the helix up off the shaft, you may want to draw in the parts with a marker to make putting it together a little faster. as you pull the helix up the secondary sheave will unscrew a few inches. you will have to turn it back to your marks to put it together. again...




not a great picture of the spring but, above there is but one hole it can go in and belew on the helix there are 3 or 4 holes.
factory setting is #2.
#3 is for slowing down how fast it shift by adding more rotational tension.


onside the clutch you will find 3 plastic buttons that are replaceable wear surfaces.


they can be pulled ..or pryed out if let go to long and there is nothing to grab any more


the surface of the helix should be checked for wear to see if it went metal to metal and destroyed the surfaces. this will cause it to not work right.


the two halves also separate...


and there will be some shim washers between them to adj distance for belt wear thickness...

OK it revs up after engagement and then settles to 5000 rpm in ditches and fields? Sounds to me like the secondary spring needs to be moved to the 3rd hole for better backshifting.

If it is dropping that much after hitting peak, then you should also check the spring in the primary. Weak or broken spring will also cause this action.

Yep, something up there should not fall that far back.
