69-7300 MB Mk-H7 Ejection Seat Restoration |
Disassembly |
Since I have two seats, my first seat out of 0286 I left original as it came out of the jet, I figured it would be neat to have one that looks 'Brand New'. So, I decided to do a complete "Ground Up" restoration on this seat. I totally disassembled the seat down to individual nuts and bolts when possible. There are some items that are riveted together. I did not disturb these. It was hard enough finding some of the special hardware never mind MB rivets. Bead blasted everything that was going to be painted. I sent some of the black and green pieces out to be anodized. The black pieces had some scratches and wear marks. The green pieces were faded. Everything that was bead blasted was cleaned, primed and painted. All the nuts and bolts, if I didn't replace with new, were wire brushed with my little Dremel tool. The parachute pack, parachute pack back plate, drogue chute container, ground egress handle, center eject handle, face curtain assembly, leg garters, seat and back cushion are all new. The rocket pack is a duplicate of an original that's on my other seat. Before attempting this project, I would definitely obtain all the manuals for this seat that you can get your hands on. It may look like a simple project, I thought it was, but once you get into it you'll quickly find out different. I even have another seat to go by but, without the manuals......... Oh yes, be prepared to make some "special" tools. You'll need them for both disassembly and assembly. The manuals are a must for disassembly and a larger asset when it comes time to put everything back together. Disassembling the seat, getting everything cleaned and prepared for painting, priming and painting takes a considerable amount of time if you're doing it right. It took me about three months to do the whole project. If you think you can remember how everything goes back together, unless you have a photographic memory, think again. I know I don't. If you have a digital camera, take photos. If you think any of these photos will help you with a seat project, feel free to print them. |
