My original '71 Peterbilt - 1693 Caterpillar is experiencing water in the oil syndrome and the head is being diagnosed and repaired at a local machine shop. The machinest says he must have the arrangement number for the old Cat in order to rebuild the head correctly. Sounds reasonable. I am at a loss at locating the arrangement number. It does not appear on the tag bearing other numbers like serial number (65B11639), bore & stroke, rack setting, etc on the motor's rear gear train cover. Was the Arrangement number recorded by tag or stamping anywhere on the early production 1693s? Any thoughts on how I might determine the number on my engine? Is there another way for the machine shop to set my head up corectly working backwards from the current timing and advance of the motor? (which I also do not know) Is there an original baseline or factory specification I can reset to without throwing other power system settings out of whack? Does Cat have a coporate office where such arcane information can be obtained?Any tips or advice would be greatly appreciated? Roger in the Nation's Capitol

Usually an aluminum tag is affixed to the gear train cover, or under the passenger side of the head on the block. The engine serial, and arrangment numbers are stamped into this.
I don't know how Peterbilt is to work with but Mack will supply the information the truck was built with.
I have two 1693TA series engines and if your type matches mine, I'll grab a number for you. I expect your external equipment would be different but the internals and settings should be the same if yours' is a TA series, (aftercooled). Does your engine look like either of mine with the ribbed aftercooler on the left side, (driver's)?
As a final note my wife works for Cat in Peoria, and could probably get the information from archives as the engine was supplied to Peterbilt. I don't know how complete it would be as the vendored engines were set up much different from truck to truck.

Rob- Thank you for your kind offers. The numbers on the tag affixed to the side of my gear train at the rear of the 1693 are these (only): Serial: 65B1639 6 cylinder Bore: 5.4 Stroke: 6.5 High Idle Engine RPM: 2305 Full Engine Load RPM: 2100 High Power level at sea level: 325 Rack setting: .040
I see no other tag or no other numbers.
My engine is turbo charged I know and after cooled I believe though the aforementioned tag bears no TA. The tractor was bought new by Pattons Trucking Company in 1971 and hauled groceries from Southern California to Alberta Province in Canada through the Rockies. They pulled heavy 20,000 miles per month with codrivers. Presumably it was set up accordingly with specific 'arranements' which to my knowledge have never been tamperd with. Any guidance you can provide me is greatly appreciated and if your wife working for Caterpillar Peroria has a means to supply the numbers for my machinest that would also be terrific.
Roger

Hi Roger, having a 65BXXX series serial number should have everything like mine does internally. I'll get a number tonight when I get to the shop. They were very similar internally unless a "Brakesaver" was incorporated. One of my engines has it, the other does not.

I can still get on with the cat web and the serial # 65B11639 has no data for it.Here is what comes up with your serial # and a few hundred around it. No Physical Data was found for this change level...I would call cat but it maybe that they did not need a AR # with that engine.It should have been on the data plate if so need it.

I check both #s and when i leave a 1 out it tells me that i need to have 8 #s in the serial # so i guess the 1693 is too old for the SIS on cat web.

Ok here is what i just found out from one of the old guys from warren cat. He said that the engines and parts were the the same . They have a aftercooler or not and if it has a aftercooler then its AR # will be the same as all after cooler engines and the turbo would be different as well but all other parts are the same. He said if you can find a engine that looka like yours then use the AR # but good luck finding it. He said they did not put it on some engines. If itr dont have a after cooler then use the AR # from a look alike. But for as head parts like vales and guides and seats he said all 1693 have same parts.Scraper or truck engine has same pistons and heads and injectors.The rebuilder should not need a AR # to order parts.

Thank you for trying Glenn. Rob- In the picture of your red 1693 the black and white aluminum/paper tag on the side of the gear train at thhe back of the motor and lower left hand of your picture is where I got the numbers I've listed above. No TA however. The other tag visible in your red engine picture is near the six fuel lines each serving a combustion chamber. I have no such tag on my engine. Do any numbers appear on that tag on yours? Like the arrangement number? Thanks.
Roger
