Frame Serial Number


Recommended Posts

Found it! Right where it is supposed to be!

Can someone point me to the transmission (TRT72) and rear end (38K tandems, I am told) serial numbers?

I will send all these numbers off to the museum with a donation!

The trans numbers are hand stamped into the case just behind, or below the TRT72 stamping. The rear axle serial numbers and specification number is stamped into the rear rear axle bowl, (not the drop in) just to the right of centerline and should start with SWDXXX, (SWD is a 34,000# rating suspension).

Hey leversole we have seen pictures of all inner workings of your 615. Where are the pictures of the outside in daylight?

That pesky job (read as monetary support for my new Mack project) of mine keeps me away till almost dark every night...here are a couple though...more to come.

The rear suspension under that truck are 40,000# plus rated with the acorn caps and two piece axle shafts.

The bowls are covered in grease, are the numbers at the "south pole" (bottom) or the front, back, or sides on the upper part of the bowl?

Maybe I can get lucky and scrape off only a few pounds of sludge!

Thanks

Should be stamped just to the right of the plug you fill, and check the oil level at. The is the rear rear axle. The stamping will be fairly large, about 1/2 inch tall.

38,000# suspension. I suspect someone has changed something as the drive axles appear to be two piece using the acorn style cap on the driven ends.

The axel ratio will be stamped into the flat pad area just to the left side of the driveshaft yoke usually at the top rt. side of this pad.
