QuestionQUESTION: Hi I have Kohler 12.5 h.p. engine mod# cv12.5 spec 1237 on a lawn tractor. The problem I'm having is getting the sump off ? it has a oil pump in it with metal lines going from oil filter to sump and 12 bolts. I have taking the 12 bolts out and the pump cover and gears out oil pump still in also i have tap and tap and still won't break loose. it has a perminent rubber seal not a paper one. Any suggestions would help a lot! Thanks so much for your time .
ANSWER: Hello Allen:
>>Are you Sure the Seal is Rubber and Not Permatex Form-a-Gasket?
>>Usually the Sump is Either a Paper Gasket or Permatex Ultra Grey High Torque. This is a High Temperature Form-a-Gasket Maker/Sealer.
>>Sometimes you have to Use a Flat Screw Driver or Thin Flat Chisel and Wedge it Between the Sump and the Block. Make Sure ALL the Bolts are Out of the Sump before Doing this.

AnswerHello Again Allen:
>>Are you Sure the Model is a 12.5-1237 and Not a 12.5S-1937?
>>I cannot Locate a Spec #1327.
>>Not Being Able to Locate the Proper Manual I Assumed (which I should Know Better than to Do) you had the12.5 Kohler with the 12 Bolt Pan. There are 14 Bolts in the Oil Pan/Sump. The 2 Bolts you have Missed are Not in the Outer Section of the Oil Pan/Sump, but are Located Towards the Inside Section of the Oil Pan/Sump.
>>USe the Following Site Addy to Locate these Screws.
>>You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM (Kohler) and Enter the Model and Spec Numbers (12.5S-1937). Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View.
