I bought a set of crank cases on eBay, without doing my homework--my bad.
What I thought would be a set of cases for a DuraForce ended up being a set of M-Series cases for a 5HP Commercial mower.
P/N for the top half is 614493, also has D2 and date of 91 with a clock which might indicate 9-11-91? P/N for the bottom half is 613109. Part number for the top and bottom assembly is 680503.
PRICE IS "OR BEST OFFER"--I don't want to throw these in the aluminum recycle bin, so if you can use them, please let me know.
Fits (at least) the following models:
22260, 22261, 680501, 680503, 680522, 680523, 680549, 680562, 680563,
680564, 680567, 680568, C21ZMR/MRA/MRB, C21ZPR/PRA/PRB, CM21BMR/EMR/ZMR/ZPR, EM21BMR/BMRA/EMR/EMRA/ZMR/ZMRA/ZPR/ZPRA,
M21BMR/BMRA/BMRB/BMRC/EMR/EMRA/EMRB/EMRC/EMRD/ZMR/ZMRA/ZMRB/ZMRC/ZMRD/ZPR/ZPRA/ZPRB/ZPRD.
