Kohler Magnum 20 ring job engine repair

[Daryl Helwig]

My repair manual isn't very good. It says to unbolt the cylinders from the crankcase and work them off of the pistons. At this point it does NOT mention opening the case to disconnect the pushrods. It then says to reverse the proceedure for reinstallation. However, it does not say how to slide the cylinder back over the piston (and the rings). Is it possible. Or do I need to go the long way around and disassemble the crankcase, put the pistons back into the cylinder (from the outside) and then bolt the pushrods back to the crank?

I have never worked on an engine the has a crankcase that can be split open and has cylinders that can be removed. Whats the best proceedure?

Right now I have the outside parts removed and the heads off.

My goal is to hone the cylinders and install new rings. Also needs a valve job.

Any recommendations will be appreciated. Thanks...

Split crankcase and sleeves are common on better engines. Sounds like you are in over your head. Can't / won't attempt to explain how to overhaul an engine in a few paragraphs - or to explain tools such as ring compressors.

Take your "basket" job to a good repair shop and hope they are kind enough to take your job. Basket jobs are usually the worst.

All the Kohles service manual I seen has al the info needed to do the repair. Either you dont have the skills to do the job of you dont have a proper service manual. From what you have stated in your OP take it to a shop and have it done properly as I dont think the service manual is your problem.

If you are doing the rings there are about 20 other things to repair or replace and check in the rebuild or you are waisting your time.
