Serial No Confusion

I have an Oliver 77 Industrial, 1951, ser no. DSL 403245 C77G. It has a Waukesha 6 cyl diesel engine, ser no. D1868006. I am considering a rebuild of the engine next summer. In investigating potential parts, I have run across the reference to serial no. 6503 (including parts on this site). It appears that there is a basic change occurring after ser no. 6503 as there are different part numbers for 6503 and earlier than for 6504 and later. This situation appears to apply across several lines (e.g. 55, 66, 77, 770, 88, 880) in both gas and diesel. The Oliver serial number listings on this site do not indicate any such numbers for the 77 line of tractors. My parts book for the tractor also lists no such serial numbers for any of the 77 variants. I am confused. Can anyone explain the 6503/6504 deal?

Thanks in advance,

You have what is know as a Fleetline 77. Since it also has DSL on the serial number it is an older diesel. The diesels were introducted in the fall of 1950 in simple terms. Fleetline tractors were made until the fall of 1954. That 6-503 serial number is where the Super Series start. It is like Larry said you have a 2 inch crankpin but the mains are the same size as the supers. Myself I would go with a 3.500 bore kit. Questions/

I take it that the term "Fleetline" refers to the 77 (and some others) prior to the Super Series, sometimes noted as "Non-Super"? What is confusing to me is that I have seen the 6503/6504 numbering reference used for both the non-super and the super 77. It seems so out of place in relation to my 403245 serial number. Of course the parts listings could be incorrect. I would explain where the listings are that I am talking about but it is a sales competitor to this site. I don't want to annoy Kim and get blacklisted.

Do you have any comment on the service manual (1400 pgs) available from this site? It seems to cover both the super and non-super 77 models but is kinda pricey. I would like to get something better than the I&T abbreviated manual that I now have.

The last time I had the head off (about 15 yrs ago), I made a note in my owner's manual that the actual bore was 3-1/2", which doesn't agree with the 3-5/16" bore noted for non-super tractors. I could have been mistaken in the measurement or perhaps the diesel version did have the larger 3-1/2" bore. Is there a source that you would recommend for a 3-1/2" sleeve assy kit for this engine? My email is open if you care to respond that way.

Thanks again,
Rod

3 1/2 is the standard correct bore size.Places like to sell the larger bore thats used on the newer tractors,and only sell the one size for all.

The very first engines in the fleetline tractors had differant pistons rods and bearings and sleeves.The rods were NOT offset in the pistons.They quickly decided they needed to change to the offset type.Unfortunatly those older ones are only a small number of tractors and everyone only makes parts for later ones.If you have the older one then you have big problems.The best fix i have heard is to go buy a newer tractor.There is probably some machine shop out there that can modify parts to fit.
