D8R +463 in 1/5,6

[D8R]

Today's report
Decided to haul dozer inte workshop again for dismantel.
The good side, have done it some times now and is very easy to brake down into pieces.
The bad side, I hate oil, and oily you get. Always oil in all tubings, valves and that is coming out when you don't want to.


As you can see everything has to be removed, incl one side of track to get hydraulic motors out. The valves (with blue servos) will be removed and replaced.

Decided is to seperate the 2 drive circuits from rest of hydraulics (blade , ripper, 463). If that will make dozer run is to be seen. The other hydraulics will be a seperate system with electrical driven pump, smaller valves, same as you guys use for models with bigger demand like excavators. Supplier can be Premacon or Tobias Breaker. With this change a complete new tank (diesel in 1:1 machine) will be built with new pump and motor built in. This is needed anyhow if, IF dozer should be electrified in the future (should have done that from beginning )

A question for you used to build with electric motors. Any suggestion of supplier? The size and design on dozer requier 120Nm torque on each side and with a 1:4 reduction in hub results in a 30Nm (rpm between 80 and 250 for correct speed). 12V or 24V? Type of elec. control?
Space available is W 7,5" L 20-24" H 8" for everything incl battery.
Thanks in advance.
