Depends on what you have and if it is correct for the serial numbers.
Several filter evoltions occurred for the D4400/D4600.
My power unit engine..serial number 1S4877.
Direct electric start.
Kind of high output at 51 horsepower at 1650 rpm no load and 1550 full load.
Others i have read about are a bit less.
not sure of the year.
Has the large injectors with the single threaded retainer.
The fuel filters (4 of them) look like socks mounted to a plate under the cover.
Does the fuel go into the center of each filter and then up to the top where it then goes to the injection system ?
Im a small engine gas guy (millwright by trade).Not sure how i got into small gas stuff cause this Cat is so much better.
However the Cat thing is a bit off my scale.
But im learning every day thanks to you folks.
Thanks Chris

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
