Hello people that know so much more than I about engines....posted a previous post with a picture of my engine, was actually my first post on this site or any others. Have read a whole lot of the posts on here trying to determine what my engine is..I could really use the help as I need it for work and personal use..Also would need to know where I could get rebuild kit if possible once I know what engine it is... I gather that the F600 means it is a 6 cylinder but what does the A 533 mean and other letters... Somebody on here posted that measuring the length of motor says what Continental engine it is ( would have go back to fined out who this was)...mine measures 24" (basically the head) all of his measures were 25" and up...f226 etc.If true then does that make my engine some other make that a Continental ...Looks like the F226....If I need more pictures I can do that...Had a bd220 in grader and crankshaft broke ...caused pulley and large timing gear to break and make crack inside case next to front seal...Used this other engine (flathead 6 ) out of another503 grader but was burning so much oil have to rebuild.. Don't know if I could fined gear and crank for bd220 (crack doesn't go through the outside of the case as far as I know but am leary of it... Help would be greatly appreciated
