Hello fellow elements individuals, technicians, truck drivers, or anybody else who’s experiencing the headache of a misplaced or lacking engine serial quantity. If you’re studying this, likelihood is you’ve gotten toured the web in search of such info. Trust me, I have completed the identical factor. Not an entire lot out there’s there? So, I determined to take it upon myself and do the analysis and publish one thing that I hope can be useful for somebody.

First a bit of historical past as to what prompted this text. I am employed by probably one of the best truck dealership within the land. We within the service division have many, many fleet accounts that we care for. One of our accounts has an International glider. A glider is principally a cab and body rails. The engine, drivetrain, and rear axles all come from one other donor truck. Sort of akin to constructing an enormous mannequin. This specific truck was married to a H.O litre Cummins midrange engine and a S velocity trans. Whoever put this truck collectively uncared for to report any info relating to engine, what sort of a truck it got here out of, and so on. Needless to say, the engine is a nightmare to seek out elements for. I searched the web in vane, however might’nt provide you with something strong to attract from. Hence, this text. Let me undergo the totally different engines and share with you what I have discovered.

Caterpillar – The ordinary spot to seek out the engine R/I is on the valve cowl engine knowledge tag. If that is lacking, Cat is actual good at stamping the R/I on the suitable aspect close to the rear of the engine. I have no idea if this is applicable to all of the engines, however I know it is there for the large bores.

Cummins – The engine knowledge tag is riveted to the entrance accent drive cowl on the drivers aspect of the engine. This can also be the place the important elements record quantity or CPL will probably be discovered. If that is lacking, on the massive bore engines, Cummins stamps the engine R/I on the appropriate aspect of the block close to the oil cooler. Now the dangerous information, the small bore engines – O.N, H.N, H.O litre engines, would not have this stamping. What I do in my state of affairs is to take all half numbers seen on the engine and insert them into your net cumpas program. A little trace, Cummins wraps injection strains on the mechanical engines with metallic tabs which have half numbers on them. I know this can be a crap shoot, however it’s a kick off point. Good luck

Detroit – Like Caterpillar, the valve cowl is the perfect place to seek out the engine R/I. I have been out of the Detroit scene for some time now, however I consider that additionally they stamp the quantity on the block. Series 50 and primarily collection 60 engines are the primary streem for such a powerplant. Although there are nonetheless a slew of the previous 8V-seventy two’s on the market in busses. Also the gasoline pincher H.P litre continues to be on the market as properly.

Navistar – The good ol’ 466 and 530 fashions. Once once more, the engine knowledge tag on the valve cowl is the perfect place to start out. On the drivers aspect engine block, there’s a block casting quantity that offers you an excellent begin, too. If the engine is the unique engine within the truck, line set tickets will inform the R/I. If performing an in-body overhaul, particularly on a older truck, do your self a favor and double examine the precise engine quantity towards the road set.

This goes for all of the engines listed above. The truck S.I.I. is probably the most effective place to begin to getting the knowledge required to get the right elements the primary time. Freightliner, Kenworth, and Volvo use the final S digits of the S.I.I. International, Sterling, and Ford use the final H digits. Mack is slightly totally different. They just like the final S digits of the S.I.I. and the mannequin sort of the truck.

I hope this helps somebody alongside the best way. Most individuals will know this info, however somebody hopefully will profit from this. Be correct in your search, and let’s hold the wheels of America Rolling!!

Thanks for studying.
