Pre-Install Firewall/Nosegear Spring Assembly

Pre-Install Trial Fit Nose-Gear to Firewall

Lots of parts attach to the firewall and all seem to cross, overlay, or abut so rivet locations must be checked and adjusted against the adjoining parts. Check & double-check locations. Clecoed channel doublers (7F7-8C) in place for the steel sprig arms pin. Drilled out pin holes (5/8" dia) through both 7F7-8C doublers and the 7H7-2C channel. Located and scribed position for the steering arms pass-thru on either side of 7H7-2C. Prepared Rear (7F8-4) and Front (7F8-5) Lower Bearing plates. Nylon Lower Bearing (7H7-4C) will need to be split for mounting to the twp parts of the lower bearing plates so that the nose gear assembly can be removed.

Firewall Modification for Viking Steel Spring

Firewall (7F7-1) Layout for Viking Steel Nose-Wheel Spring

Firewall & Viking Steel Spring Nose Gear Components (Powder Coated)

Cold-snap. Worked in office on firewall components lay-out. Scribed firewall (7F7-1) reference lines. Scribed rivet lines on vertical lower channel (7F7-2C), vertical top channel (7F7-3) left & right firewall stiffeners (7F7-5), and top channel stiffener (7F7-7SP). Scribed rivet locations and bungee pin holes locations in left & right channel doublers (7f7-8C). Verified pre-drilled left & right gear gussets (7F7-9C). Since I am replacing the elastic bungee supplied with the Viking steel bungee, laid out locations for 9mm mounting holes for the upper viking gear assembly on the upper channel (7F7-1SP). The upper channel supplied with my kit came pre-drilled for the spring/gear-tube assembly. Dis-assembled the Viking spring assembly, primed, and painted mounting legs and spring.
