yea I learned that the hard way

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





and a quick peek of this





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 this is just a trial to see if I can make a pump from the scrap pile

[dirtpusher9]

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?

yes I actually put it together and tried it , have some seal reworking to do . It leaked between pump and motor . Yes ,I'll be the guinea pig on this 1 ,and will not give up till it works . need less to say nothing will be running anytime soon , lot of small parts to make . I need to get some chunks of aluminum to make 4 trannies for the scrapers , 2 reversers for this , valves , and pumps . if the vain is a no go then back to the gears .

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 ) . now on to the next unaffordable part valves . I think I'm going to wear this taig mill out with these 3 machines

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?

[SmallHaul]

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 .

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 .

only a little , Joe , welded up 1 track frame tonight had to get 68 steel wheels to the powder coater now got to finish the hubs for them and the next batch . my rollers will be hard ( cummins cam followers ) ? for you did you use bearings in yours or just a brass bushing ? I was thinking sealed bearings but may go with oil lite bushings and looks like the $ is keeping me on the make it my self path for awhile . got the shaft seal for the pump just didn't get it in yet .

[dirtpusher9]

yea I'm leaning more toward them It's not like the full size where it take a couple hrs to change 1 .
