    Clutch for Eaton 15 speed and rear main seal for a 4MG 3406B. Needing some part numbers, thanks.

    The rear main should be a 2W-1734. I can't give you a clutch number, but the opening in the middle of the flywheel is smaller on the B models than newer engines I believe, so a newer 1850 easy pedal may not fit. I don't know enough to tell you specifically, just be aware that it can cause a problem.

    Sure can cause a issue. Lesson learned the hard way!

    Unless someone has updated the flywheel to the 10inch center bore it will be a 8.5in center bore flywheel. The 8.5in center bore clutch I usually use is Eaton easy pedal P/N:108391-74, Eaton only offers a 1650ftlb clutch for the 8.5in bore anymore.

    Thankfully I learned this valuable lesson on a 9670 IH B model, 13 speed and was putting trans in from the top. You can not get trans to mate to engine.

    Stupid me. Double check the parts guys work.
