How to change the flywheel

The Fly Wheel provides the necessary inertia to carry the engines pistons through the stroke of the cycle. The teeth that surround the Fly Wheel used by the starter to turn the engine over till it starts up, then the teeth eventually become worn over time. The hardest part in this process is is just trying to acessing it. You will need a wrench, drip pan, flare nut wrench, tranny jack and tranny fluid. First step it removing the drive shaft from the back of the tranny. How you do this is, disconnect the drive shaft from the differential. The driveshaft attaches to the differential with two bolts, which are in the shape of a "u" know as the u joint. Each bolt has a single nut on both ends. You are going to need to remove these with a wrench.




Next pull the driveshaft away from the differential, now put the drip pan under the back of the tranny were the driveshaft enters. Pull driveshaft towards back of car in order to remove. Let all fluid drain. 


Second, Disconnect the speedometer cable, shift linkage, and tranny cooler lines from the transmission. These three components need to be disconnected with a wrench. The cooler lines need to be disconnected with the flare-nut wrench to avoid damage. Third, Put the jack under the drain lift jack until secure under tranny oil pan. Fourth,disconnect tranny from engine. Take off the four remaining nuts used to attach the trannys torque converter to the back of the flywheel from under  the car using a wrench. Disconnect retaining bolts used to attach trannys engine block with a wrench. Fifth, Remove trannys cross member, this holds the tranny to the cars frame. Now pull tranny toward rear of car to reveal the flywheel.

 Remove flywheels retaining bolts located in the center of the flywheel with wrench. Pull the flywheel off of the crankshaft, position the new flywheel against the back of the crankshaft. Then install and tighten the bolts taken out with a wrench. Sixth, attach the tranny back to the engine. Sliding the trannys against the back of  the engine with trannys jack. Make sure that the suds on the torque align with the holes on the flywheel. Install and tighten torque converter with the nuts you took out and again using the wrench to do this. Install the trannys bolts through the front of bellhousing and into the back of the engine, tighten bolts with wrench. Seventh, Install trannys cross member onto the cars frame. Connect the two cooler lines to the tranny with the flare-nut wrench. Also connect the speedometer and shift linkage to tranny with wrench. 


Eighth, pu the driveshaft back in the tranny by sliding it in the back of tranny. Position the rear of the driveshaft against the differential. Lastly install and tighten the four nuts into the two "u" bolts with a wrench. Add transmission fluid into the dipdtick. YOURE DONE !!!
