I bought a really clean lawn boy gt18h a couple weeks ago. Owner said that the engine had a rod knocking realling badly. I picked up a good engine for the swap and began today. Tore it down... and first thing I notice is that the driveshaft universals are just destroyed on the front half. We're talking like 1/2" plus of play.... with no actual cap on one of them. I'm hoping this is what he was thinking was a knocking rod,.. and that the engine is actually good ( Haven't tried to fire it up yet ).

My question is this, I am trying to pull the driveshaft out to go have it rebuilt by a local guy,... how does it disconnect from the hydro pump?? I've removed the five allen head bolts, disconnected by lines, and have the housing worked out about 1/2 inch, .. but I just cannot get it to fully disonnect and let go. I don't want to go prying and breaking something if I am going about it wrong, so I thought I would ask here. Any help is greatly appreciated.



*Edit* After a little more looking, I finally found the set screws that hold the driveshaft on. Loosened them up and slide the driveshaft right off. On a very bright note,.. as suspected... I just fired up the "blown engine" and it purrrs like a kitten.
