    Hello all. I need to replace my clutch on my celect+ and I see three different part numbers for a flywheel: 3609903, 3609890 and 3609903R

    Is there a variance on these three? I cant re use my current flywheel because the previous owner before my last clutch swap six years ago used a smaller clutch that gouged the FW out of spec.
     
    Rideandrepair and Bean Jr. Thank this.

    I’d check Dealer if you can’t find the answer. Your vin # will tell original build. If your lucky they’ll give you a part #. Maybe ask for an estimate for Clutch job, if you have to. Estimate should show all part #s needed. I’m sure they’ll flywheel is $1600. I bought one on Amazon. $240. Lot of aftermarkets out there. Just as good as Dealers. Mines done a good job.

    Hello, all. Thanks for the replies. I called cummins Southern plains and they said 3609903 and 2309903R have a removable ring gear. Found one at a salvage yard. Because it was $3200+ shipping for a new one.

    Fleetpride had flywheels on sale last month for 135.00. I bought a stack of them for different engines.
