I'm thinking of leaving the tracks wide instead of cutting the 1/2" off to bring to scale width . Kinda looks like a wide track . I'm going with the single motor drive , just to see if it is possible in RC . I got pretty much figured out , just the time and parts http://i830.photobucket.com/albums/z...r/PIC_0635.jpg http://i830.photobucket.com/albums/z...r/PIC_0638.jpg and a quick peek of this http://i830.photobucket.com/albums/z...r/PIC_0641.jpg http://i830.photobucket.com/albums/z...r/PIC_0642.jpg I still have to machine the shaft and bolt together to test flow and pressure . only non calculated variable is the motor ( not sure if it has what I need ) but we'll see :confused: this is just a trial to see if I can make a pump from the scrap pile :o |
Re: dresser TD40B dozer
I'm glad your going with one motor and steering clutches, you can be the guinea pig to see if works.lol Any more progress on the pump?

Re: dresser TD40B dozer
well I got my pump working :) still got to get a shaft seal , A quad ring just not going to cut it :( ( should've known better :o ) . now on to the next unaffordable part :( valves . I think I'm going to wear this taig mill out with these 3 machines :eek:

Re: dresser TD40B dozer
Nice work on the pump - a vane pump you say. Wow, nice work. Would a press fit bronze SAE863 collar on the shaft help seal it? Are you planning to make the valves? If so, are you going to do a closed or open hydraulic system?

Re: dresser TD40B dozer
Nice progress Steve. Pump looks good!
Those HD brand servos I told you about on the phone don't like to sit for a long time under load, they have so much holding strength that they burn up from heat. So, they probably would be good to move/hold valves. |

I'm might try something off the shelf first . not sure yet on open or closed . as for seal , I just used what I had laying around to try it out . Quote:
thanks Scott , any servo holding a load for a long period of time is not good for it , I would think . I'll cross that 1 when I can get to it . |
