Found this site with lots of RX7 manuals. The 1988 Diagram is found under the "1988 factory manual" (no pic just text) Link http://www.wankel.net/~krwright/cars/rx7/manuals.html Good luck This is another good one: http://foxed.ca/foxed/index.php?page=rx7manual#firstgen
First, which belt do you mean, the w/p, alternator belt or the w/p-air pump belt? Water pump, alternator belt is the innermost, air pump and w/p is the middle one, a/c is the outermost and has it's own pulley on the crankshaft http://foxed.ca/foxed/index.php?page=rx7manual#firstgen Download the full 1983 manual from here, in it there is an exploded view and steps on removal, disassembly, etc.
I want a good repair book like a haynes or chilton manual like they have for American cars. I know that they are available for the 2nd gen's but I havent been able to find much for the 3rd gens except fot that performance handbook at bookstores which really doesnt offer much to help you maintain the car. If anyone knows of any good repair or maintainence books for the 3rd gens or maintanence websites please let me know, thank you. http://foxed.ca/foxed/index.php?page=rx7manual#firstgen I use rx7club.com as well.
