Hey guys I have some information wich is intresting reading. Attached some pics to. Spesifications; Year: 1950 Make: chevrolet Model: 1/2 ton 3100 1 series pickup truck Engine: GM 6 cyl. 235 CU Transmission: Manual Transmision Speed: 4 Speed Saginaw Patricks conversion. Wheel Drive: 2 Wheel Drive Additional Information: Sir My truck have a torque tube and a closed rear end system ! The rearend has a 3.55:1 ratio and the patricks Saginaw 4 speed conversion (short tail peace) with a 2 groove input 10 splines, gears 1st. 3.11/2.20/1.47/1.00. Wonder if posseble to install your O.D. together with this setup ? Martinius Berg Answer; We have a universal torque tube kit. You will cut a 15" section out of the tube, weld in our adapters to the outer tube and inner shaft, then the overdrive bolts into the torque tube. This requires some minor machine work and welding, but it is a simple job. I attached a picture of the unit. The price of the kit is $3295. Let me know if you have any questions. Thanks, Nick http://www.gearvendors.com/cg2wdt.html
Sweet ! I don't suppose you know if this unit has freewheeling and maybe a cable operated lockout ? . Overdrives are great but NOT for in town use ! .
Answer Hello Nate How are you , this is what it says in there brosjyre. I have some moore spes. install information i can publish here wich i am able to a bit do later today. You will have a 2-speed thumb switch on your shift lever to control the GEAR VENDORS (turning it on/off) while depressing your clutch. Hope i gave an answer to your question.
More Information about the install of the OD. Torque Tube Kit one sheet The installation of our torque tube kits are very straightforward. The kit is supplied with two flanges on the overdrive itself and two mating flanges with the same bolt hole pattern and centers are supplied for your mechanic to enlarge the centers to fit your torque tube. The internal driveshaft couplers are supplied with center bores for your mechanic to enlargen to the same as your shaft size and weld in place. In basic terms the process of installation is as follows. A)Remove the torque tube from the sphere end at the transmission and mark the position of the internal shaft relative to the torque tube length (how much does the internal shaft stick out beyond the torque tube measure presicely). B)Mark the tubes 12 o:clock position - so you know where up is and can position the overdrive so it looks exactly correct and is not canted off a few degrees. C)Pick the spot in the torque tube that you want the overdrive to sit - before you remove the torque tube from the vehicle - you want the overdrive as far forward as possible without the up and down movement of the suspension carrying the overdrive into the floor or tunnel. The only benefit to keeping it forward is that it is more out of sight and has less impact on sprung weight (the closer to the diff it is there could be some stiffer ride over bumps as the torque tube moves more at the diff than at the trans and will now have the od weight as well to move). Having said that, we have never had a customer notice anything but better ride quality not less. D)Now you are ready to remove the torque tube from the diff and mark it up for the length (flange to flange) of the overdrive that you will cut out of the tube - and the length coupler to coupler of the internal shaft modification (remember that you internal shafts will go inside the couplers and be welded there so allow the proper depth. E)Weld on the flanges to the torque tube being sure to get the bolt pattern correct for 12 o:clock. Weld on the internal couplers (orientation does not matter here) it should be that your internal bore size of the coupler is almost a press fit so you get a good true running shaft - check total run-out with dial indicator before welding in place. F)Mount the torque tubes to the Gear Vendors and slide in the internal shafts and then mount to the diff and sphere to complete the installation. G)Fill with GM 12346190 or Mopar 04874459 fluid – easiest to fill with finger pump plungers sold at the autoparts stores (like a windex plunger but with a hose on it so you screw it on the one quart bottle and pump in until it runs out the fill hole. Drain and refill every 5k miles. No need to ever take off the sump just drain at small allen headed port out the rear of the sump. H)Electrically the overdrive can be activated with 6-12v direct to the solenoid. You can either use our manual switch assembly or any latching switch you feel looks good in the car. Many classic owners prefer to put a switch on the dash that matches the rest of the vehicle knobs (ie: a push pull switch) and that does work fine except maybe when splitting ratios and moving the shifter at the same time (as in going from 2nd over to 3rd direct). You can put the green lamp we supply on the shifter circuit – just do so in parallel not series. In other words run your ground to one lead of the overdrive solenoid and your 6-12v to the other lead of the solenoid through your switch. Now hook the light up to the ground and then to the lead of the solenoid after the switch. I)Important: Do not operate the overdrive or leave it on in reverse – binding inside the overdrive will result. Do not leave the overdrive “on” at speeds below 15mph as the overdrives pump pressure is driven by output shaft speed which is lower the slower you go. J)Tips: Since the overdrive is shifted hydraulically and the pressure comes faster relative to driveshaft speed note: In high gear push in the clutch, select the overdrive, let out the clutch and you will be in gear. I low gear, preselect the switch then within one second depress the clutch and let it back out and you will be in the overdrive gear. In 2nd gear, select the overdrive and immediately depress the clutch. K)Tips on outshift smoothness. When you outshift the overdrive, everything in forward of the overdrive will need to speed up 28.6%. You will find out shifting the overdrive is smoother at lower speeds as in turning it off as you are coasting with the clutch in preparing to stop or down shift. If outshifting at freeway speeds move the transmission shifter to neutral during your clutch depression and then back into gear after you click out the overdrive will also promote more smoothness.
