Ya know to me it only makes sense to thread it down all the way. I really miss the old automotive style dipstick on these Kohler motors. It was Idiot proof!May or may not affect you newer CC owners equipped with Kohler engines - and that were only given Cub manuals for their machines with engine maint stuff directly included in lieu of a separate Kohler engine manual..
Seems that Kohler revised their oil level checking procedure on at least the courage vertical twins early this year from "chk with dipstick resting on threads" to " fully thread and seat the dipstick cap in to obtain correct oil level chk" . The CC manual that came with my new tractor did not reflect this change.
The related CC owners manuals have not been updated nor a bulletin issued to reflect such... to my knowledge.
The Kohler manual number referred to here is 32 590 01-B revised 2/09 for my engine, a SV710-0019..
Really dunno about what potential harm may be done by running engine effectively a tad overfull of oil, but don't relish a possible ticking time bomb going off later, either. But, take this info FWIW to you... each to his own.
