The part that the seal and retaining strip are riveted to is the external surround that holds the Plexiglas in place and is bolted to the frame with flush head screws. I think you will have to remove this to replace the seal. There is very little room between this and the aft face of the frame making it very difficult to drill out the existing rivets. Cherry Max rivets will likely not be an option as there is not enough space for the rivet stem. If you are able to get the old rivets out without damaging the very soft retaining strip it may be possible to use short 3/32" POP rivets. > > However, you can remove the surround without removing the windshield or center section glass though you would have to re-seal the glass on re-installation. > > Sorry for the misinformation. > > Walt > > -----Original Message----- From: keithmckinley > Sent: Sunday, October 13, 2013 7:52 PM > To: yak-list@matronics.com > Subject: Yak-List: Re: CJ canopy seal > > > Thanks Walt, > > It's very hard to see looking directly at the area but I do see what you mean looking at the detail in volume 1.

The cable is not stretching, your swedge might be slipping or the gob/ball of solder (on the stock cable) might be giving way, but the cable is not stretching. I would estimate that 75% of the guys who adjusted their cables because of "stretch" had the cable break soon after the adjustment.

Dennis Savarese" Subject: Re: Yak-List: Re: looking for help with "mushy" brakes on CJ 1 - The cable is probably stretched because there isn't much adjustment left 2 - You should remove the wheel assemblies and check for glazed brake pads. Then check for a broken or missing felt grease seal on hub. It's the grease seal that fits into the large "cup" behind the rear bearing. If the felt grease seal is messed up or missing, grease from the rear bearing will sling outward onto the drum and brake pads causing the brake pads to glaze. Once glazed, the brakes will feel 'spongy'. Clean the brake pads with avgas and dry thoroughly. Then scuff the brake pads up with 60 grit wet/dry sandpaper. Dennis A.
