The person selling them said they had 50 hours on them, and by being almost void of carbon, I think he was telling the truth. I had another pair of heads I bought over 5 years ago off of ebay. My digital camera won't take very good closeups. I'm wondering if this was the start of my problem with the leaky one. The worst dent at the bottom was where my gasket had begun to erode "blowthrough". It has 3 dented in places where whomever was assembling the engine wasn't careful. I did find on the head which was leaking what appears to be some headgasket mateing surface damage which only could have occured during assembly at the factory. I completed the head gasket replacement, and must say it is a straight forward jobbie. Looks to be a straight foreward job, and the engine can stay in the tractor frame.Īny additional comments, or words of advice. ![]() Do I have to remove the lifters, or can they stay in their bores, and just remove the pushrods, and label them, intake, exhaust, top and bottom. Should I do both heads, even though the left one is not leaking?ĥ. Will the Kohler "improved bolt" kit I bought work fine?Ĥ. Do I have to pull the carb off first, or can I remove the carb and intake as an assembly?ģ. Can I do this repair with the engine still on the tractor?Ģ. Tractor is a John Deere built Scotts 1999? 2554.ġ. I have a shop manual for the John Deere Saber 2554. Slight leaking can be heard from right at shut down. This is suppose to be the new fix for the leaking head gasket problem. The Head gasket stud kit is no longer available, but I have purchased the Kohler kit # 24-757-31 with the new bolts, with reduced shanks. ![]() Hello all, I have the Kohler CV25S Command with a leaking right hand side head gasket.
