66dc75 Posted September 16, 2018 Share Posted September 16, 2018 My buddy Victor who owns this 39 ED is looking for a 4 speed direct and higher ratio gear setso he can get up to about 40mph with it. Right now it's a 30 mph truck with a 3 speed and 6.33 gears. Anybody know of anything out there? Quote Link to comment Share on other sites More sharing options...
j hancock Posted September 16, 2018 Share Posted September 16, 2018 Mmmmm..... hen's teeth. Rear axle is a Clark and for the ED and the DE models you had choice of 5.12, 5.57 or 6.33 ratios. 5.12 on 17" rims will do about 45 mph without making the engine huff too badly. I am sort of toying with the idea of putting a Gear Vendors overdrive into the ED milk truck if I live long enough. Will keep my eyes peeled for two 5.12's. One for me and one for Victor.

Brocky Posted September 16, 2018 Share Posted September 16, 2018 My Diamond T 201 has the Clark rear on 7.50 X 16 spokes.. It is screaming at 40 (+/-) MPH!! I do not drive it much on the road as I do not trust the brakes that far to stop 5000 pounds.. If he plans on driving it much Jim's idea of an overdrive box is probably easier/cheaper than trying to change the rear?? Quote Brocky Link to comment Share on other sites More sharing options...
66dc75 Posted September 16, 2018 Author Share Posted September 16, 2018 I think that overdrive probably a good idea for this. Quote Link to comment Share on other sites More sharing options...
Popular Post grayhair Posted September 16, 2018 Popular Post Share Posted September 16, 2018 Ah, the need for speed is relative. The guy that owns this truck would love to make 30 mph... 3 2 Quote Link to comment Share on other sites More sharing options...
