starter ring

General consensus is to get a small drill bit.. say 1/4 or less and drill a pilot hole between two teeth, beith carefull not to get into the flywheel, and then take a cold chissle and a couple good whacks should pop it off.

Instalation is a tad harder. Usually involves getting the ring gear up to 400 or 500 degrees in an oven, or with a torch, and then dropping it on the flywheel.. tap it into place, and then letting it cool. Either way you heat it.. you have only a few seconds to get it to the flywheel and make sure it is seated, as the clearances are very minute when hot, and get very cozy as it cools.

Preheat the oven to 450, take note of which way you want the ring gear to be oriented, an put it in the oven for 20 minutes, or so.

Have the flywheel sitting an something secure next to the oven, clean and ready for the ring gear. (I often put the flywheel in the freezer overnight to shrink it a tad, and remove it and set it next to the oven just before the ring gear is "done".)

Grab the HOT ring gear with GOOD oven mitts, and drop it in place on the flywheel. Have a hammer and a brass drift punch at hand, to be sure it's seated all the way. (You only have a couple of seconds to be sure it's in place before it shrinks down on the flywheel.)

(You need to disassemble the clutch to get at the flywheel bolts. Match mark the pressure plate to the flywheel. While you're at it, mark the oreintation of the flywheel to the crankshaft, to make installation easy. Note the orientation of the lined clutch disc (which is front or back) and put it back the right way! You will need a clutch alignment tool when reinstalling the clutch. Some use the tranny input shaft, and install a new front transmission seal before putting the shaft back, to eliminate the chance of a leak there.)

Since your 9N is timed by the camshaft/distributor off-set scheme, any timing marks on the flywheel are in-material 'cuz there ain't no timing access flywheel ports on the frontmount 9N engine..... ....Dell
