Flywheel Differences
Hi There,
Looking to find out the difference in these 2 flywheels. 986-114-012-05-M37 (for a 99 Boxster) And 986-114-012-06-M37 (for a 2001 Boxster S) Is it possible to install the 986-114-012-06-M37 into a 99 boxster? Will it bolt up to the crank? Will the 5 speed transmission still be mountable? If anyone has drawings or pictures or a good discription of the difference I would appreciate if they could post them Thanks |

Some Extra info
Guess I should of stated that I am still hunting down the no idle issue - Took it to a most recommend shop here in Calgary and after 5 hrs of diagnosis their thought is the fly wheel either has bent teeth, improperly made or is the wrong flywheel. The came to this diagnosis after checking the output of the Crank Position Sensor - They checked to see if it was a bad sensor - it was not - they modified an old sensor to go closer to the teeth on the flywheel and the car fired up but timing is out and car is not drive-able - Loaded up the car brought it home and have just finished pulling everything out of the way to drop the trany on Wed night and take a look at the flywheel. My question is - if they sent me the incorrect flywheel would it actually fit? Thanks |

You might want to call the Schaeffler (Luk) the flywheel manufacture technical hotline and ask them, as they should be able to tell you if they are different. From their web site (see url below) the number is: 1.800.274.5001
Also, I believe the M37 in the part# you provided is the Pelican only suffix. Schaeffler Automotive Aftermarket USA | Products | Flywheels |

Looks like we found the issue.
Correct flywheel - bent teeth We built a stay for the DMF to keep it in place that worked off the teeth on the starter ring - and also had the pin in on the front to stop any movement while it was tourqued so quite sure this must of happened during shipping. Just missed the dang thing Here is a pic - Top is the new - bottom is the old. Still cant believe I missed this.

Flywheel supplier says on occasion the teeth get damaged in transport and asked up to straighten them out and try it first.
Straightened the 3 bent teeth just after the gap. Re installed flywheel, Clutch and Transmission, Did a test start - Fired up immediately - idled nice - WOOOO HOOOO Putting the rest of it back together over the weekend - 4 months and $2000 later we got a winner. What cheesed me is when we called the supplier when this started they had "no ideal what could cause this issue" Then when we pulled the flywheel and noticed the bent teeth and asked them what to do - "They had seen this many times ""Just bend them back in place"" I was so pissed off - Could of saved me a couple grand if they just said - Did you check the teeth on the flywheel as they sometimes get bent in shipping. Really cheesed about that part - but live and learn and send my $$$$$s else where next time. Peace Out to all those that put out ideas. |
