Not sure what the spec is on my Legacy springs for the main gear overcenter link, but they sat around for 5 years, then flew for ~200 cycles in the last six months (since first flight), and are quite robust, exerting at least 20lb force at the fully extended position.

Ed,

Very little force is required to keep the main over-center links over-center. One way to check them out is the emergency gear drop - you should see the gear lock indicators turn green whether the check is done in the air (might be necessary to slip a bit to get a green) or on jacks (it might take a few extra seconds to get the lock because of friction or no more than about 2 lbs of pressure outward against an offending wheel.

TK-5 shocks should have been adjusted to the same length as the donut assembly. This should be checked on jacks. If you have standard gear, the middle gear door may not close properly if the extended shock does not position the gear to the same position that the old donuts did when the middle doors were installed.

While testing gravity drop on my mains with dump valve open, the spring on the overcenter link seems to only exert about 5-10 lbs. force on the link at locked position. Spring is many years old but not in use. Do these get weak? What is recommended force of spring? I just installed the TK-5 shocks. The adjustment moved the tire back so that it no longer touches the hydraulic lines and centers in the wheelwell. Took maximum short position on the adjustment cam to do this. Is this typical?
