Window mechanism repair

This Pella window doesn't want to close enough for the lock mechanism/lever to catch.

Took the wood piece covering the crank mechanism off.  It was held on with three nails that were installed from the bottom of the window assembly.

This bracket has three screws and they were a little loose.  Just tightened them.

This is one o the nails that held on the cover piece.

One of the three nails's head pulled through the base wood.

The third nail is in the bottom left of this picture.

This pivot point is loose.  The screw is loose and is moving around as the window is opened and closed.

There's an aluminum cover (white exterior) over wood behind this hole.  The wood is soft and won't hold the screw.

Installed a plastic expanding drywall screw insert in this hole.  First had to drill the aluminum plate hole to 1/4".

It's also dirty.  Cleaned the dirt before reassembly.

Before cleaing, drilling and inserting the plastic expander.

Special screw with a pivot shaft for the mechanism arm to ride on.

Can't just replace with a larger screw.

back side of the cover piece of wood.

Plastic "cover" over the crank lever mechanism.

After reassembly, the window just needs a little bit of manual help at the end to close enough to lock.  Not perfect but works enough to close.
