New to the forum today not sure if there a intro ? my question on the Kohler Command I have a 1996 Agco Allis 918H garden tractor it has a Kohler Command 18 hp engine it ran great for most of the 8 or more years i've owned it last year it started smoking but ran the oil leave dropped then you had to check the level daily and add oil the right front of the cylinder showed oil residue build up from years of use one day while it was running i saw gas spurting out the same area watched some youtube videos for ideas and help after the videos i was hoping for a blown head gasket so that's where i'm at i have most bolts removed and shields but not the cooling shroud went back to the video found out i didn't remove the 2 intake bolts so i'm at that point wondering if the can be removed with the shroud in place? if not what's involved? removing the engine? do not know what and where the bolts etc. are located or what must be removed and what does not so any help i greatly appreciated since i'm in Minnesota and snow is in the forecast today i need to get going p.s. - any thoughts if it's only a head gasket or rings etc. Thanks Rich |

Today i ordered a Kohler #24 841 01-S head gasket kit after using my back up 40 year old Crusader MTD USA built 5hp snowblower i thought it's time to get going on my Agco Allis 918H the 5hp did not eat up what the county snowplows left at the end of my driveway my 918H ate that for breakfast even if it was old frozen snow chunks my U driveway it's roughly 250 ft by 10 feet wide funny how a guy gets going when the real snow & cold come and you get a face full of icy snow and frozen fingers the good if it get real bad my neighbor cleans out my driveway with his Bobcat |

update - 1st of all i should say my tractor is not up in the air so i can get under and see what's going on it in my garage which is a mess loaded with every thing i wanted inside with the snow coming which has arrived the mower deck is still under it & my jack stands are under my 50 Olds 88 so i need to borrow some stands question on removal my 18hp horizontal shaft engine from the hydrostatic drive unit on my Agco Allis 918H i did download the manual found out there are 4 mounting bolts to remove but i did not see any thing about separating engine from the hydrostatic drive unit i check around and i think taking 2 bolts out at the flywheel was mentioned so is that what i need to do? or is there more things i have to unbolt? right now it's nasty outside -4 with -35 wind chill coming so i'm not going in the garage any to soon the other thing the engine is dirty from years of cutting grass and dirt thrown up and sticking on the oil leak i'm gong to spray it down with carb cleaner i can't even see the mounting bolts when i do get it clean i'll keep it clean - lesson learned |

Pulling the 18hp engine what's the easiest method to be disconnecting the driveshaft on a 918H do you have to remove all the bolts i just saw 2 at the rear of the engine i assume there 2 on the opposite side couldn't find a diagram to look at |

Well i finally got the engine out  only took 6 monthsreason - it was covered in grease could see much and the biggest thing was lazy so the head gasket was blown on the right side as expected got every thing figured pretty much now, just a lot of clean up to do i took carb cleaner and blew out the head bolt holes worked ok until i did the top left hole with the most fins - the carb cleaned was shooting out the fin mid way down to the rear i hope that is tapped through the block from the factory and that's why this is happening - need some advice on this - Thanks |
