Terry, I'm with Digger. I have a few k-241's in equipment and the capacity is different in one. I suggest you have a couple quarts of oil on hand and add 3 pints and check the dipstick. Manuals, as you see, can differ. Especially since we can't be 100% positive on what a PO might or might not have done.
Makes me wonder why the discrepancy in the online manual that was publish August '63 to the hard copy version of February '64 that came with this 100? Was there a change in the '64 model year versus the '63 model year? The manual I have is R3 while the online one is R1.
Going now to check the dipstick.
Under edit: just check after adding a quart and half - dipstick shows full. So, 3 pints on this one.
Joe - I only ever saw a 10 hp in the narrow frame IHCC's with the flat pan, which required the really short rod dipper. The 12 and 14hp came with the dished pan and a longer dipper on the rod. I believe that continued with the wide frame 1x8/9 series. Not sure if the 10hp in the Quiet Line series got the flat pan and short dipper.
Now, how did it affect oil capacity? I know the 12 and 14hp in narrow frame, and the 12, 14 and 16hp in the wide frames had 3 pt capacity. I always thought the 10hp had slightly less - even tho the manual called them out the same.
Lets hear it from all the 10hp owners.
Do you have a flat pan?
What is your oil capacity?
