| Hey guys, I’ve got the engine out of my D17 series 1 for some engine work. While it’s out I’m going to replace the clutch. I’ve heard of having to resurface the flywheel. What am I looking for to know if I need to have the flywheel resurfaced? |

| in my opinion, it's SOP with a clutch job unless you like to do things twice. I suppose you could hit it with some 80 grit to break the glaze if you had no chatter issues |

| Resurface for sure. Whatever is removed from the clutch surface must also be removed from the surface the pressure plate bolts to. There is a published dimension for that in the service manual that I don't have access to right now. Maybe others can look it up. |

On the D15 flywheel, if you turned very much off, your clutch will feel limp. Make sure that the clutch and pressure plate are correct. Can't go by most manuals on this one. Most disc are much thicker than originals and cause pressure plate fingers to be too low. With the flywheel turned very much, you won't get needed travel to release pressure. Rick Corder can fix you up with correct clutch and pressure plate. If you notice lots of D14 and D15 tractors have a piece welded to clutch pedal rod, this was because of improper installation. A little wear on clutch then would cause throwout bearing to contact fingers and cause more wear and slippage. HTH Tracy ------------- No greater gift than healthy grandkids! |

| Haven't found a company yet that will warranty their clutch if you didn't resurface the flywheel. One even questioned if it was turned on a lathe or ground on a flywheel grinder. |

| Thanks Tracy . My clutch and pressure plate are on the way to Rick . He told me the flywheel should always be turned . Maybe I should've measured the wear ridge ? |

Is this true even if redoing the clutch on say a WD45? |

Always resurface when replacing the clutch. Asking for problems if you don’t. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

| ACinSC...Doesn't make any difference on the flat flywheels about the wear ridge...just the recessed flywheels. What's taken from the face of the recessed flywheel, has to also be taken off the top flange where the pressure plate bolts down. |

| And, yes...ALWAYS resurface the flywheel when doing a clutch job, to save you the headache later! LOL! |

| Just for the record, lengthening the clutch pedal rod on ANY D14-15-17-19 does nothing but reposition the clutch pedal itself. It does NOTHING for helping release the clutch better/sooner. The throwout brg only has so much travel and it is limited inside the bellhousing. |

| Absolutely correct! Thanks, Dr. Allis for mentioning that. I have had a lot of folks that don't understand that, no matter how much you try to explain it. :) Rick |

Exactly, that is why the height of the clutch fingers need to be set correctly. The pivot point of the fork could have been at a better location to allow for more travel of throw out bearing, with less travel of the foot clutch rod. This is why if the flywheel has been turned much ,there is not sufficient travel to release clutch and have proper clearance from fingers to throw out bearing.Very little use and fingers are rubbing bearing!
