Replacing a ring gear

On a manual transmission flywheel, if the teeth are bad, you don’t have to replace the whole flywheel. The ring gear can be replaced by itself for a lot less money. Here’s how to do it.

    I didn’t have a cutting torch to heat up the ring gear so I put it on the bar-b-que for about 10-15 minutes. Worked great! I’m sure a cooking stove would work too. The BBQ was at about 450 degrees when I pulled it off.

    Absolutely, very nicely Done !!!

    Thank you. Why cant i just clean up teeth with angle ginder and turn ring gear over. Chamfer on my ring gear is big enough on both sides to sit down flat. Also why the shim, surely if clutch is bolted to flywheel the whole assembly just moves back .020″.I have a hydraulic system and i can adjust push rod from slave cylinder to compensate the difference.

    You can also drill a hole through the ring gear and chisel it off on some vehicles

    Great video i never knew how to replace ring gear until i watched your video.Thanks for the good stuff Duane.

    Heating the ring gear makes the teeths softer. How is this afecting the harding of the teeths? Don’t they last less?

    On the install you can also put the fly wheel in the freezer for about an hour if you don’t have a oxy/ace torch. Then a LP torch should work.
    As always great vide!!!! thumbs up!!!

    What do you suppose was the cause of the damage on the original ring gear? Was it a bad starter or was it driver error for starting a vehicle that’s already running?

    @spelunkerd
    The flywheel’s just a thin piece of metal with a non-removable ring gear that bolts to the torque converter with a couple of bolts.

    That’s very cool.I’ve never seen anyone do that befor.Great job and thanks for sharing it with everyone.

    How does this look on an automatic transmission?

    Nice one Dwayne!

    I see you used a cutting attachment. What number cutting tip was that?

    I take it the decision for a cutting attachment is that a rosebud wouldn’t be concentrated enough and would heat the flywheel excessively while a welding nozzle wouldn’t heat a large enough area?

  13. Bushougoma says:

    @boaterbil Material has been removed from the flywheels friction surface. This will cause the pressure plate to push on the clutch plate a further distance when the clutch is engaged reducing pressure plate spring tension and potentially clutch grab.

    The spacer brings the flywheel forward so the distance even with the removed material is back where it was prior to machining.

    Sorry about the multiple removals my Internet connections hit or miss right now.

    Does that ever warp the flywheel?

  15. boaterbil says:

    hi, I dont under stand why machining the flywheel will make the distance from the disc to the flywheel too short. Movine the disc too far towards the end of input shaft of trans, ???

    Nice work guys.

    Another professionally informative video, thanks for everything you do. I’m just a household DIY’er and I enjoy watching your videos.

    if you turn the oxygen and gas down youll go through less gas, theres nothing wrong with having high you just go through gas quicker than you need to
