(Non-Asbestos Ring Gear)
1.
Remove all burrs from flywheel mounting face and pilot bores. Clean the torque converter ring gear flywheel mounting surface
and the ring gear screw tapped holes with solvent. Dry thoroughly, being certain ring gear screw holes are dry and clean.
2.
Check engine flywheel and housing or housing adaptor for conformance to standard S.A.E. No.3 -SAE J927 and J1033
tolerance specifications for pilot bores size, pilot bores eccentricities and mounting face deviations. Measure and record engine
crankshaft end play.
3.
Install torque converter ring gear as shown
NOTE: Assembly of the ring gear must be completed within a fifteen minute period from start of screw
installation. The screws are prepared with an epoxy coating which begins to harden after installation in the
flywheel mounting holes. If not tightened to proper torque within the fifteen minute period insufficient screw
clamping tension will result.
4.
Install backing ring and thirty-two (32) special screws to approximately .06 inch [1,5 mm] of seated position. It is permissible to use a power wrench for
this installation phase. With a calibrated torque wrench tighten screws 23 to 25 pounds feet of torque 131,2 -33,8 N.m].
To obtain maximum effectiveness of the special screw's locking feature, a minimum time period after screw installation of twelve (12) hours is suggested
before engine start-up.
The special screw is to be used for ONE installation only. If the screw is removed for any reason it MUST BE REPLACED. It is recommended that the
epoxy left in the flywheel hole be removed with the proper tap and cleaned with solvent Dry hole thoroughly and use a NEW screw for re-installation.
5.
Assemble torque converter to engine flywheel by sliding converter into position by hand before fastening housing attachment screws. This may require
more than one trial to match the drive gear teeth. Pulling the converter into position with housing attachment bolts is not recommended.
6.
Measure engine crankshaft end play after assembly of torque converter. This value must be within one thousandth 1.001) of an
inch 10,0254mm] of end play recorded (in Paragraph #2) before assembly of torque converter.
