Engine Serial Numbers – Importance
First a little history as to what pushed this article. I’m employed by possibly the best wagon dealer in the land. We in the service dep.
Have many fleet accounts that we look after. One of our accounts has an World glider. A glider is largely a taxi and frame rails. The engine, drivetrain, and rear spindles all come from another donor wagon. Kind of similar to building an enormous model. This actual lorry was married to an 8.3 litre Cummins midrange engine and a six speed trans. whoever put this lorry together neglected to record any info per engine, what sort of a wagon it came out of, for example. Obviously, the engine is a nightmare to find parts for. I searched the web in vane, but could’nt come up with anything solid to draw from. Thus, this article. Let me go thru the different engines and share with you what I’ve found.
Caterpillar – The common spot to find the engine S / N is on the valve cover engine information tag. If this is missing, Moggy is real good at stamping the S / N on the right side near the back of the engine. I don’t know if this is applicable to all of the engines, but I know it’s there for the enormous bores. Cummins – The engine information tag is bolted to the front accessory drive cover on the driver’s side of the engine. This is also where the imperative parts list number or CPL will be found. If this is missing, on the giant bore engines, Cummins stamps the engine S / N on the right side of the block near the oil cooler. Now the bad news, the tiny bore engines – 3.9, 5.9, 8.3 litre engines, don’t have this stamping. What I do in my situation is to take all part numbers obvious on the engine and insert them into your web cumpas program. A little hint, Cummins wraps injection lines on the mechanical engines with metal tabs that have part numbers on them. I know this is a crap shoot, but it’s a place to start. Good luck Detroit – Like Caterpillar, the valve cover is the number 1 place to find the engine S / N. I’ve been out of the Detroit scene for some time now, but I suspect that they also stamp the number on the block. Series 50 and typically series sixty engines are the main streem for this kind of powerplant. Although there remain a slew of the old 8V-72′s out there in busses. Also the fuel pincher 8.2 litre is still out there also.
Navistar – The good ol’ 466 and 530 models. Once more, the engine information tag on the valve cover is the number 1 place to start. On the driver’s side engine block, there’s a block casting number that may give you a great start, too. If the engine is the first engine in the wagon, line set tickets will tell the S / N. If performing an in-frame overhaul, particularly on an older van, do you a favor and double check the particular engine number against the line set?
This goes for all of the engines listed above. The wagon V.I.N. Is potentially the best spot to start to getting the data needed to get the correct parts the 1st time.
Freightliner, Kenworth, and Volvo use the last six digits of the V.I.N. Global, Sterling, and Ford use the last eight digits. Mack is a little different. They like the last six digits of the V.I.N. And the model kind of the truck. I hope that this helps someone on the way. Most folk will know this information, but somebody hopefully will benefit from this. Be correct in your search, and let’s keep the wheels of America Rolling!!







UK based fresh air Power has voiced an understanding with Volvo to development and incorporate their Dual-Fuel technology into Volvo van engines. Dual-Fuel is a patent-protected system which will enable heavy duty diesel engines to run on up to 90 % natural gas with a tiny quantity of diesel fuel..
