RW753 Posted March 3, 2009 Share Posted March 3, 2009 (edited) I am thinking about puting a T2060A in a R-Model single axle dump with a 237. The truck has a 4.88 rear ratio. Has anyone used this combo? I am concerned the step from fifth to six may be to great. This is not a work truck.

HK Trucking Posted March 3, 2009 Share Posted March 3, 2009 With that rear end ratio it will not have enough reduction in low gear for off road work.It'll sure fly down the road though, I didn't do the math, but I'd suspect 80mph+ @ 2100 RPM.

GearheadGrrrl Posted March 3, 2009 Share Posted March 3, 2009 IIRC, the 237 Maxidyne puts out over 200 horses clear down to 1200 RPM, so it'd probably handle the upshift OK. The 2060 has a low range gear, so it should be able to start up any load unless you're pulling an extremely heavy trailer. For a "play truck" it'd probably be just fine though.

Lmackattack Posted March 3, 2009 Share Posted March 3, 2009 yea for a play truck it would be ok but for any soft off road work... good luck Im with Herb 80+ if the 237 can keep up. it will however get you back from the truck shows on time!

David Posted March 3, 2009 Share Posted March 3, 2009 With 1100x22.5:2100 RPM in direct = 51.6 MPH1254 RPM in overdrive = 51.6 MPH2100 RPM in overdrive =86.4 MPHIt takes forever to shift from direct to overdrive. By the time you get it in gear if your speed drops to 45 MPH you'll hit the fuel at 1100 RPM's. If your going up hill, keep it in direct!

RW753 Posted March 3, 2009 Author Share Posted March 3, 2009 (edited) I like this tranny for it's simplicity (T-2060-A).The "A" does not use an air shift. I don't have a chart for the A but I am assuming the ratios are the same as the air shift . The unit is the a complete take out w/ a pto. The R model I want to put it into only has 17,000K on it so I don't want to mess with the rear if I don't have to. It has a little 5 speed direct in it now that looks like a quad with out the compound. I want to be able to run about 70 with out buzzing at 2100 rpm so I think the ratio is ok if I can only get there .I will also be putting a Jake on it which will be helping with my shift.

David Posted March 3, 2009 Share Posted March 3, 2009 Again assuming 1100x22.5, 70 MPH = 1700 RPM. Quote Link to comment https://www.bigmacktrucks.com/topic/8504-2060-with-a-237/#findComment-31674 Share on other sites More sharing options...
RW753 Posted March 4, 2009 Author Share Posted March 4, 2009 Again assuming 1100x22.5, 70 MPH = 1700 RPM.The truck has 10 X20" tires on the drives, 11Rx22.5 steers. All the tires are like new so I guess I will leave them on for a while. I won the tranny on E bay for $500. It is complete with the shift lever, tranny mounts, PTO and the yoke. Now I can install the transmisson and get a new driveline made. (there is a fire pump in the driveline now)Thanks for everyones help Quote Link to comment https://www.bigmacktrucks.com/topic/8504-2060-with-a-237/#findComment-31701 Share on other sites More sharing options...
David Posted March 4, 2009 Share Posted March 4, 2009 The numbers are the same for 10x20's as 1100x22.5. Both are 498 rev's per mile. The recomended max for your new driveshaft is 60" in length.
