Another KAT on the prowl

[rc_farmer]

I bought this new swing ring. It is approx. 2 1/4 across from inside to inside. The Slipring from rcwd will not fit insode this ring. You will need a slipring smaller than this one. The pinion gear is large thus taking up the space inside the ring. The ideal slewring would have an external tooth.....for that i am still searching. Also i purchased the slipring that is advertised on the KAT website.....it is not going to work either. The wires are somewhat bigger than human hair. and the turntable is about the size of 6 stacked quarters.

The Leimbach is external teeth. Contact this place in Germany to get it. (I doubt you find part/price on his website).

Much ablidged Joe

Nice upgrades Rob!! Will you use the RC4WD radio for this machine or just a standard?

[rc_farmer]

I did got the new slewring but the pinion takes up most of the space. That rc4wd slipring is huge. I ordered the one from Germany.

Jake: I'm going to use my Airtronics, it has all the mixing features i want for the pump operation.

Hey Rob you rdoing an excellent job on this, im interested to know how strong that new slew bearing from china is? would it be suitable for a bigger machine? are the gear teeth metal or plastic?

cheers

[rc_farmer]

Here are several pics of the new slewringw with and w/o the pinion and slipring.











The new ring teeth are made of metal.

[rc_farmer]

Well, I think i have figured out the slip/slew ring problem that has been plaguing the KAT. The pics will explain.

I cut and shortened the rc4wd slip ring down to a workable height










I bored out the diameter of the slew ring to fit the diameter of the slip ring. This not fits atop the slip ring.

Hey rob glad you are getting things worked out with the rotory ..Sometimes it takes a bit to find something to fit ..Question ..your opinion on the tracks ..are they cast aluminum and do they look strong enough ?..they look pretty good from the photos

Hey Lou, yes they are cast alum. and they are pretty beefy. I think they are worth a buying to build other projects. I actually bought extra links too.

Glad you got it figured out now you can move on forward

who makes the cylinders? i'm having nothing but trouble with my kat..
it will spend most of this weekend at cabin fever on the lowboy

[rc_farmer]

These are the replacement for the original ones. I got the second version of the KAT and it came with smooth cylinders. Once i figured out the hydraulic, everything else was pretty easy. What are you having issues with....im no expert, but maybe can shed some trial and error experience.

[bigford]

stupid stuff. cylinders leaking the pump is shown as
a brushless but i got a brushed and it screams to make
the cylinders move. you cant do more then one function at a tim

[rc_farmer]

You are absolutely right about the brushed pump....if yours is like mine was, the coupler is off-centered too and it wobbles. It sitting in my junk pile. I bought the brushless the same time i bought the unit. I also junked the valves too. These valves are from tawain. they work great. I drilled the open from 2mm to 4mm for a better flow. What you see in the vid is after the mods to the valve block. i cleaned the threaded area REAL-GOOD and applied TL to the nipple and let set....no leaks there and no leaks .....so far from the heads.

[bigford]

are you using the morpower valve??

[rc_farmer]

Yes i am and Hitec servos

[egronvold]

It's very quick. Good job so far!
