This is NOT a case of the nut falling off the crank…although that did happen!! And, it took its toll on the adapter and belt. That was the two days I spent in Mertyl Beech sitting on my tail!! The real problem is that the belts are WAY TOO TIGHT when properly installed. This is NOT a pully alignment issue…theyre properly in line with each other. Its a “Spacing” issue. Its like the inner primary places the engine too far foreward…or the transmission too far to the rear….but ends up with the belts stretched so tight that they can barely be installed. And…when everything heats up…its so tight that theres a real potential for bearing or shaft failure from the pressure. Basically….its just NOT right!! And….the Primo rep looked at this in Mertyl Beech two years ago…and knew what the problem was…and hes the one who told me about the different size belts…with the secret small blob of paint to identify if they cured larger or smaller than spec. And, after buying 3 more belts trying to keep the bike on the road…I basically didnt ride it at all last summer due to this problem. And, the Primo people were supposed to send me the larger belt….but never did. So….the bike just sits!! Just help me fix this one issue…and Ill consider the rest as owner maintenence. But this…shouldnt be. Thanks for your further consideration.

Administrator(1) If you had a nut come off… check the spacer. Im not kidding.
(2) If you are convinced its the inner primary, you can get a new inner primary for around $250. The thing is these are all cast and usually do not vary (but I guess it could happen.)

(3) As Primo indicated the belts do vary, but if youve tried three… When trouble shooting demons its best to go one component at a time.

SubscriberStephen,
I have an 04 Vindicator 6 speed and Ive had the crank shaft nut come off twice now. When you say check the offset spacer thats the splined gear that goes over the crack shaft, the one that is bolted to the 45 tooth front sprocket right?
This spacer dimension of 1.4375″ where do measure this from?
Now I need a new spacer and nut Im sure they dont make a spacer that is 1.4375″, when I have this machined down does it have to be 1.4375 is there a plus or minus there? How did we get such an odd dimension? Is there anything else I should look at before this goes together again?loop-single-reply.php

AdministratorThe spacer is billet and it is between the motor and your inner primary.
Its hard to measure on the bike because you need to put a dial caliper on the spacer to check the dimension.
The 1.4375 is 1-7/16 that is one 1/16 less than 1-1/2. Weve had them taken down to 1.4 and work. The scientists on the group will tell you about rotational force and if the pressure is on the outside it could cause the nut to come loose.
Over the years Ive become convinced we got batch of wide spacers. It seems the issues are in late 04 early 05 bikes.
