    Hello all. I've broken two return springs already, and have talked to several others locally who have broken quite a few as well. Are others having this problem on their Boss V's? Has anyone found a solution for fixing this problem? Thanks

    Boss has introduced newer tapered springs for the wing return on all new v-blades. Your blade can be easily modified to accept these new springs and will solve your problem of breaking springs (provided you are overtightening them) :)
    BOSS Part # MSC07705 and can be found online @ www.cuttingedgesnow.com for $28.45 plus shipping under their Common Replacement Parts Section.

    Broken a few myself and even ripped the bolt hole open. Make sure they are not to tight and put washers on both sides next time.

    The longer springs now reduce the possibility of the installer over tightening them. Which is the main factor in shortening their life span. If you breaking springs often then they're too tight.

    The springs require very very little pre-tension to retract the wings if the center hinge is lubricated as intended. In fact a screen door spring from the local hardware store will retract them if the hinge is greased properly.

    Would a string tied to the end of the wing and pulled from the inside of the truck work just as well?

    Your daughter strong enough to pull the right wing in for you? If so, then yep.

    A snow bank is easier though. :D

    Thats freakin funny Grandview. Maybe we should design a pulley mounted to the center tower where 2 string could go thru one tube and into the cab...

    Make sure they both go to the pass side window. He'd still make his co-pilot pull them both. :D

    I've Busted 2 springs in1 year it ain't from being to tight. both of my springs broke in the same place. when I got replacements I showed the broken one to the boss dealer, he said they all brake there. When I should them to a friend that is a metallurgist he said it was in-proper manufacturing that weekend the spring.

    so I keep 2 on hand.

    How do I go about patenting this?

    Or maybe he will mount another pulley on top of his passenger side mirror

    Are you using the procedure as recommended by Boss?

    He's probably fabricating mounts as we speak to install Western Cylinders:laughing:

    Nice thing about spring return is you only run the pump half as much to move the wings. Easier on the pump, motor, battery and alternator. 3 less valves, 3 less coils, 2 less hoses and related wiring to work with too.

    Simplicity is redundant. Can I borrow some of that popcorn? :D

    I keep what ever springs the part store sells ,Meyer springs work just as good and break just the same.

    Use a business card to gap between the springs. A good trick that Sr. B&B had told me. :drinkup:

    Ditto. Mike I hope the bowl is big enough for me. :nod:

    I agree GV. Also buying extra, longer eye bolts will make things easier.
    It looks like you didnt use enough FF, I hope you have a welder.
