 Topic: New damper plate doesn’t fit flywheel Alto da106Posted: September-08-2020 at 6:28pm |

I’ve got an ‘87 ski Nautique with a 351w. I’ve pulled the transmission for repair and bought a new damper plate to put in while I am at it. I bought an alto da-106a from ebasicpower. When attempting to bolt the damper to the flywheel, the damper will not sit flat because the rivets holding the center section of the damper together make a circle slightly larger than the circular recess in the center of my flywheel. (Roughly 1/10th” larger)
Has anyone else run into this issue? Can I put spacers behind the damper plate? Or should I grind the flywheel a bit? I don’t want to throw anything off balance. Thanks John |

Other people with the same problem have used washers as spacers.
Here's an old thread in the link below, that discusses washers. It was for a damper plate for a PCM transmission but the idea is still the same Eric in that thread ran a transmission rebuild shop Fantastic Finishes Marine in Ohio. No fair grinding on anything  |

You could call Joe at FFM and discuss it too.
He's the new owner Rumor has it that he did all the real work anyways, while Eric spent his days posting on CCF Here's a link to his contact info |

I just bought one fit perfect on an engine that had a PCM trans in it's past life. As an added bonus I ordered and paid for a 106- was going to trim it myself. Received an already trimmed one. Should have bought 2
