Before you start this step, go to the link posted two posts below so the crank shaft flange will be correctly aligned with the flywheel or you could be 180 degrees out. (faint arrow on the crank flange should point up and faint arrow on flywheel near center should point up)
Crank shaft flange. Dowel pin/bolts marked in white: Dowel pin close up: Flywheel timing marks: (note new pilot bearing) Flywheel bolt through crank shaft flange. These can't be removed or replaced without removing crank shaft. Slide open end wrench behind flywheel to snug nuts. Torque to 41 foot pounds: Clutch disk marked "flywheel side": Using spare input shaft for alignment tool: Pressure plate snugged to flywheel, only 14 foot pounds torque. Then remove alignment tool. From left to right: Transmission bearing retainer, release bearing carrier, release bearing (throw out bearing) Clutch spring on Passenger side and clutch fulcrum on drivers side of carrier: Drivers side release/throw out bearing with clutch fork fulcrum. Fork fingers fit behind top and bottom tabs on carrier (between tabs and transmission bearing retainer)with indent on fork riding on fulcrum. Edited by ralf - 09 Dec. 2010 at 12:36am |

Good question. don't have answer. Some one who is a real mechanic will have to help us out. All I did was put the bearing in the freezer and the flywheel in the oven. (When my wife wasn't home)

I would freeze the bushing, and remove the flywhell and heat it in the oven, the bushing will drop right in with little or no force. Yes you can tap it in with a similar size socket.
Every clutch that I install I take the the shop to have it surfaced anyway, so just give them the bushing, they normally will not charge anything if you have the flywheel surfaced.
Caution, before installing the bushing, check to make sure it will slide on the end of the transmission first, I have seen more than one bushing that was either too loose or too tight.

I don't think a little rust will hurt. You may want to hit it with steel wool and some fast drying solvent. It gets wet and will rust after installation anyhow.

Just a question about the flywheel bolts and their orientation. When I removed my motor only the dowel pins were installed. The 4 other bolts were put in with the nuts on the motor side not the flywheel side like in the above pic. The motor is currently at the machine shop. Do I need to take the bolts to the machine shop and have them installed into the crank?

The bolts are special bolts that are supposed to be inserted on the engine side of the crankshaft. They have both shallow heads and large and long shoulders that don't allow slop between the bolt and the crankshaft flange and the bolt and the flywheel.

Good info - I have been all over the web looking for the torque - I never would have guessed 14 pounds. I have done them before just guessing, I know I cranked them down real good - a lot more then 14 pounds. I have to hunt for a manual at Gilbert. I thought I could find one on-line, a free download

Ok - I found my old Chilton manual - IT SAYS torque the clutch to 25 pounds. Where did the 14 pounds come from? Good thing I can reach the bolts trough the access cover
