I have developed the well documented leak at the sump gasket that looks like it is coming out of the oil filter. I was finally able to get the cleaned up and jumped my safeties so I could actually see it running. The drip is coming down from the sump but is getting blown on the back of the filter mounting plate, then dripping down. I've researched what I need to do to get the engine off and plan on replacing the gasket and the shaft seal. Most things I've read on this caution against replacing the split alignment pin and substitute an alignment pin that doesn't have the split. The gaskets seem to be packaged without this but with an o-ring. I have found a part number for the pin but some of the pictures seem to show a solid pin and some pics still show the split. Can anyone furnish a good Kohler part number for this pin without the split? TIA.
Please help with parts lookup Kohler CV20

Intelligent search from Bing makes it easier to quickly find what you’re looking for and rewards you.
This is just from what I have read: There are 2 locating pins between the sump and the case. One (or both) of these had a split in them when originally built which contributed to the blowouts on the sump gasket. Supposedly superseded by a pin that didn't have the split in it. I think this may be the number https://www.jackssmallengines.com/j...5hezwljftkh8nwc01ikpmreqttixnepyaaoo5ealw_wcb
This is the breakdown (I think) of my engine sump, showing a gasket. It is on a 17yo Dixie Chopper. https://www.partstree.com/models/cv...-20hp-14-9kw/oil-pan-lubrication-3-24-502-11/
To be honest with you I’ve never, ever replaced one of those pins, plus as Star said, no gasket just sealant. I don’t know where you are getting your info from, but I would seriously question the authors. Here is a service manual for your engine, I would follow its instructions. https://www.mymowerparts.com/pdf/Ko...d-CV17-CV18-CV20-CV22-CV25-CV22-CV23-CV26.pdf

Only on parts like sumps that are rarely removed
Parts like rocker covers that should come off every couple of years need gaskets .
I once got the crankies & charged the customer a full hour for removing all of the silicon from his intek twin rocker covers.
HE bitched about it then found out the B & S techs charge 2 hours to adjust the valve lash for exactly this reason.
Probably fit better than 100 intek rocker gaskets to engines that were originally glued on with silicon.
Bert, this guy has a Kohler, not Briggs, and I’m just passing on the service manual instructions. Most Kohers call for gaskets in all other areas, with a few exceptions. In this case Briggs is in a different ball field and I agree with you, no sealants. I have found that you can remove sealant from valve covers very quickly with a wire wheel, but I did ruin a few before I learned how to do it without heating the metal. Now it’s a 5 minute job.
