All,
I have a LT155 with the Koehler CV15s and I had the lifter tick and then low power. Measured lift on the end of the push rods and getting measurements of .177 intake /.192 exh as compared to the factory specs of .353/.360 lift.
So I'm pulling the engine to go through it.
#1 Question: How do you get the PTO pulley off the bottom of the crank so you can remove the engine from the frame? My pulley has 2 really small holes in it 180 degrees apart. These holes are 3/16" dia. Didn't want to use the standard gear puller on the outside flanges of the pulley so to not bend them up.
#2 Even though its not aprts yet, its fairly certain the cam and lifters will need to be replaced. Was going to go ahead and do a completed rebuild, and replace all bushings, bearings, seals, and gaskets. Any other suggestions of know issues to replace or upgrade while I have it apart?
Does the replacement cam/lifters still have the same issues that causes this original loss of power due to cam wear?
I'm all ears. Thanks in advance for any help any can offer.
Steve
