Center prop shaft? How tight should it be? Pretty snug? Warranty for bolts breaking in the hub? How do you know if the bolts are too long or too short? And last but not least the center prop shaft ID threads... is there supposed to be a bolt/washer that will tighten down on the spacer? Mine sticks past the spacer about a 1/4" or so...

Thanks for any info you can pass on... just about done with my Superkraft Laser 2000...

The center shaft needs to be tight. The best way I know to set it is to double nut the shaft, put a little silicone on the shaft, and screw it in. Then put a wrench on the outside nut and tap the wrench handle firmly with a hammer. This will snug the center shaft and hold it until the silicone sets.

I'm not sure what to tell you on the rest.

Hope this helps some.

Good luck

You shall never ever tighten a bolt more that the recommended torque that it's label with.

All depends on how much torque you shall use, do a search on the Internet and you will find the momentum of every bolt. On how long the bolt shall extend into the hub is like we use when we design a new construction, if it's steel 1.5 times the bolt diameter but if it's aluminum 3 times the bolt diameter.

Thanks for the input. On the ZDZ the center shaft has OD threads that thread into the hub that is ID threads... so I can't really put a double nut on it. As far as the recommended torque.. I haven't found what the may be... General torque based on 1.5 for steel and 3 for aluminum is a good starting point... I was hoping someone found the torque from ZDZ directly... More than likely I'll just end up snugging it up nice and tight and go from there... just check it from time to time to make sure it's not getting loose... My other concern is the smaller bolts and the warranty issue...

Thanks again for your input...

Have a good one...

1.5 and 3 times the diameter of the bolt is how long the bolt should be.
