I phoned Bobcat parts team. For whatever reason, they cannot match engine serial numbers up with engine model numbers. Others(engine rebuilders) tell me they have in the past and they don't match. Anyway, they said to order parts based on the machine serial number not the engine serial number...

Maybe someone at the factory punched in the wrong serial number???

Yes, my engine model number and serial number placement is the same as yours. Right in the casting. It appears I have the rotary injector system. I purchased the machine brand new so there have been no engine replacements.

I guess my problem has been that my engine serial number is 690522 which according the experts is not a 4JB1 engine

My serial number for the bobcat is 510250237 so it looks like it would be included under your rebuild part number. Don't know if I want to tackle a rebuild myself. Sorry about the heat. I'm sure doing anything in that heat is tough.

So do you think all the 4JB1 engines put into 853's are the same? I notice the description in the ad shows 853 and 843 models but those are different HP engines are they not? I needed a new injector line and the dealer suggested their were 4 possibilities. I ended up ordering all four and of the...

Will give it a try. The original company would probably help me out.

I've had a terrible time ordering parts for the engine from the dealer. They are totally confused and have no answers. I've actually asked two dealers to find me a replacement engine and nothing... I'm sure everything is original as I purchased it new.

Looking to get 4JB1 engine rebuilt however the Model number does not match the serial number. Professional rebuilders won't touch it. Isuzu dealers no help. any ideas?? the engine is original.
