Hmm, I'd doubt 37" tires. Maybe it was the rear axle of the wagon and there was a transmission involved... Actually now that I think of it Dad might have mentioned something about that. He claims to have seen the rig years later before it was sent off for scrap but never saw it in action.

Some rough calculations - with guesses. tire diameter in inches 30 tire circumference in ft 7.853982 road speed, MPH 20 road speed, feet/minute 1760 tire RPM at road speed 224.09016 differential ratio 4 driveshaft (PTO) RPM 896.360639 PTO RPM is typically 540, as I recall, so 900 RPM is a bit fast. Try again with other numbers tire diameter in inches 37 tire circumference in ft 9.686577 road speed, MPH 20 road speed, feet/minute 1760 tire RPM at road speed 181.694724 differential ratio 3 driveshaft RPM 545.084173 There. With a 37" tall tire, and a axle ratio of 3:1, the numbers match up. *smiles* It's withing the realm of possible. -- Philip, avoiding work. _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
