Re: 445 Engine rebuild.. 22hp Kawasaki FD620D-AS 00-01
I will be looking at doing a rebuild soon. I purchased a 445 last August, with 206 hours and it's using oil. It loses about 1 qt every time I cut grass, (about 2 acres). After I bought it and got it home, I notices a slight blue smoke at high rev. Someone had bypassed the blow by tube that goes to the bottom of the plate on top of the carb/fuel injection, (where the air filter is located). I got the parts from Deere and fixed that, hoping that would help, but no such luck. The mower runs fine most of the time, a little ruff when I engage the PTO on the mower as it warms up, but then smooths out. No smoke at low to mid range rpm, but very noticable at higher rpm.
I know I need to do a compression test, both wet and dry. Then start a parts list. I have learned as discussed here, this Kawasaki engine, was only built for John Deere, and the parts are Kawasaki, but have a John Deere part numbers (and price). It is hard to cross reference and compare the cost between Kawasaki and John Deere.
Please keep posting your findings and progress.
