  1. Can anyone tell me what the speed ratio's are on a Mack T2070 transmission for reverse on up. I have a customer changing it to a T2080 and wants to know what the difference is. Thanks for the help please.
  2. I have a RW613 with 4.42 rears and a t2090 trans. Truck came with 24.5 rubber and we switched over to 11r22.5 . The speedo drive is worn out and not working, and I want to get the right ratio so the speedometer runs true. The "adapter" as the parts breakdown calls it, has a ratio of 1.132 from the factory. Can anybody help me with the correct ratio? Or if anybody has a serial number for a truck with the same specs but factory 11r22.5 tires that would work too. Thanks for any help
  3. Curious. Was looking around at tachometers (and cables). Noticed some older mechanical tachometers on other trucks and even on farm tractors. Seemed to be made by the same folks who made the broken one in my R. Maybe Stewart-Warner??? Does anybody know for certain what the ratio is on the OEM tach that would be found on these old Rs or even Bs? 1:1? .5:1? Something else?
  4. I know this has been thrown around plenty ...but where exactly is the tag in the axle that contains the gear ratio..im swapping my rear diff for one that has been factory drilled and tapped for the transverse torque rod bracket and I would like to be able to check the ratio in the axle that I plan to buy in order to match it to the ratio in the front diff.... Im doing this cuz it would be easier and cheaper to go to the scrap yard and swap the owner my working diff for one his ..just would have to pay a lil difference in price but definitely cheaper than drilling and tapping... Also since im just swapping the diff itself and not the whole axle , would this be a direct drop in fitment or the axle and diff have changed over the years?.would I have to buy a corresponding 1996 model diff since that's the year model of the truck? Please advice RED Ps:Picture is off the web and not the exact diff I would be buying.
