1993 Mazda Rx7 - Rotary Engine Rebuild - Part 2

Intro - Part 1 - Part 2 - Part 3 - Part 4 - Parts List - Final I have stripped everything down to the short block and now needed to remove the large nut off of the back of the eccentric shaft. The socket needed is either a 2 1/8" or 54mm. If you need either of these I would suggest to ch eck your local Harbor Freight or go to HarborFreight.com. If you have trouble locating the socket online, give them a call to get pricing for a set that includes one of these sockets because I have seen them on the s helves and the whole set is cheaper than any single 2 1/8" socket I have found elsewhere. Next, you will need to secure the flywheel which will prevent the motor from turning so that you can remove the flywheel nut. You can either purchase a flywheel stopper/brake or simply grab a few feet of solid copper wire and wind it through a bolt hole and around one of the clutch alignment pins on the flywheel as I have shown in the photo to the left. This worked perfect for me,
