Rockwell axles under W500's

[Gordon Maney]

Are they marked Rockwell or Timken?

The transfer is Rockwell?

In 1957 I think both axles are Timken and are split case.

The rear becomes a "Rockwell Standard" sideloader within the next couple of yrs & stays that way throughout the W500/600 run, ending in 1977.

The front stays split case through 1973 but somewhere I think it picks up the Rockwell name. I am guess Rockwell bought out Timken at some point.

Rockwell Standard became Rockwell International maybe in the 70's

Timken was big in the railroad industry & I believe came up with the roller bearing.

Both my 65 W500 & 75 W600 have Rockwell T223 t-cases. I seem to have read where Canadian W600's may have had the much smaller NP201 T-case in the 70's.

My 1968 W500:
Front axle tag states "ROCKWELL STANDARD CORPORATION" FDS-750BM-X3
Rear Axle is listed as a "TIMKEN H 141"

W600

My rear reads Rockwell H141
Front is FDS 75HDX 75

Both say Rockwell Standard div of Rockwell International.

Prior to 74, the 6.8 was only ratio available.

74-77 were 6.2 (maybe 6.17, too lazy to go look) if Dana 70 front, otherwise still 6.8

The Dana 70 W600 had a lower GVW & were more common than those with the Rockwell FDS front.
That Dana 70 front was only used 74-77 mainly shares only the housing with the Dana 70 that was used in W300's.

Here is a very, very brief history on the Meritor home page. Meritor is the current name of the company that has the Rockwell/Timken lineage.

Funny you should post that history..

My dad went to work for Rockwell Standard in Ashtabula 1965. It was called the brake plant at the time. He was transferred to Fairfield Iowa in 1978, and the Ashtabula plant closed up a few years later. I started at the Fairfield plant in 1988, when I was 18. That place was primarily off road (it started out as a supplier to John Deere Ottumwa) and marine equipment up to 88 or so, and they eventually took on more on highway product due to consolidation. We built driveshafts, axles, etc. for Caterpillar, Volvo, Mack, Mercury Marine...
I quit in 97 (and went to work for John Deere) before the name changed to Merritor.. but up to that point, I had lived on a Rockwell paycheck all of my life.
The Fairfield plant closed in May of 2002.

Another sad plant closing.
