| I was just looking at the second of the three photos for the W A I for 6-25-09 showing the tandem suspension arrangement used under the IHC AR 626-F trucks which is noted as Dual Drive. Was this type suspension ever available under the early 1946 to 1951 Westcoaster WC-6564-OH trucks from the factory? Reason I ask is in about 1985 I saw two different IHC Westcoaster oil field rigup winch trucks , both out of service , one complete and the other minus winch and headache rack , in Tulsa Ok belonging to American Rigging ,that had this suspension under them and have never seen any reference to them being an option for the early Westcoaster and in fact never seen another truck at all with this type suspension . I guess they could have been originally under AR-626-F trucks and the Westcoasters could have been glider kits but it seems kind of early for gliders in the late 1940's. Anybody have any input.

| Does that mid 1930s AR 626-F use Hendrickson suspension? I've always wondered if early Hendrickson tandem design used that radius rod in front and if so, when did they discontinue it? There was earlier discussion about Hendrickson but we never specifically talked about that front radius rod. Timken tandems used the front radius rod but they would not have used the walking beam, correct? Bruce

Ed I have the Crestline Book International Trucks by Fred Crimson. On page201there is a picture in bottom left corner of the largest W series built during 1946. It has the front torque arm same as pictured in WAI photo.I never saw one on a Hendrickson Walking Beam myself. Itcould have been an early production feature. I had and worked with quite a few heavy rears from Rockwell 50,000 STDDto 65,000 and Macks 80,000 rears.chocko.
