Removing flap springs to install SK 217 doubler

[thediverdude]

I need to remove and then install the flap return springs to install the Service kit M20-217. Is there a spring stretching tool or something that makes this job easier? I am imagining a tool similar to that used on automobile drum brake springs. We broke oneof the spring ends trying to remove it. So will need at least one replacement.

Just had a similar question with respect to the giant gear spring. I think it will work here too. Grab a stack of washers of great diameter than the spring. Bend the spring back and forth to open the coils and insert washers in the openings. This slowly extends the spring to install. Put flap down, spring stretches more and washers are loose or fall out. Let us know how it works.

popsicle sticks work well

Thanks for the reply's. I did the washer trick and it worked great.

Did you have the doublers fabricated or were you able to find a kit? I’d like to get this SB done on my bird as well

Maybe a picture of the doubler for general shape and size and going to  43.13 for the specifics on sheet thickness and rivet

spacing would affect the "repair" appropriately. 

Even if a crack is not visible yet, it is still a repair.   "Repaired bulkhead at flap attachment location with doubler- etc etc" 

Accomplishes the same thing as the kit does.

I bought the  doubler from Laser. They have the whole  kit for $295.40 with a 2 wk lead time for the entire kit or just the doubler for $57.60. I Bought just the doubler as the rest is easily fabricated. The doubler came within a week of order. Now to install it.
