Re: dresser TD40B dozer
 

Just beautiful, a dream coming true for you Steve. To scratch build something like this is truly amazing. Like Joe, was just wondering what your weight currently is and what is the approximate total weight when finished? I have the RC4WD Dozer and it is just around 50 lbs, and ripping very hard clay is a challenge, which I like, but yours with all that steel should really dig, if you do add the ripper?

Nice job!!! Looks like you spent many hours on the track parts and drive....wow.....I would have run out of patients long before getting all the track pads on the links!! Lol. Keep up the nice work!!
(This dozer is 1/10 scale right??)

Re: dresser TD40B dozer
 

I will add a ripper at some point . It'll be real close to 100# when done .

I assembled them while waiting on tool changes or part switch out on the mill and lathe, so I had some break time in there . Scale is just a hair bigger then 1:12th .

Re: dresser TD40B dozer
 

I got my sabertooth 2x32 , it came with 2 resisters . I'm drawing a bit of a blank :o:confused:( brain on overload) as to where I'm supposed to put them . Across the motor leads ???

Re: dresser TD40B dozer
 

Steve-If I remember correctly you put one from each motor lead to the motor case. Been a while since I did this so you may want to check with someone else but I am pretty sure this is how I did it. Worked good, no radio glitches.

Re: dresser TD40B dozer
 

YES, I believe you're right.

Re: dresser TD40B dozer
 

The Capacitors are to keep motors from sending emf noise out. If just 2 caps, they go from each lead to the motor can. 3 is better, with the other spanning both leads. Shorter legs are better so they can't act like antenna.

Re: dresser TD40B dozer
 

Guys these are resisters not capacitors . I'll have to contact dimension eng to see why they put the resisters in with no diagram as to placement .

Page 9 and 14 where it's talking about voltage clamps and braking?

Re: dresser TD40B dozer
 

thanks frizzen, I downloaded it a while back . Brain is proper now and I read threw the publication again . It turns out they're not needed in this application . I bought this 1 from robot shop and not Dimension, it turns out they add stuff to the package for same price as from dimension .

Re: dresser TD40B dozer
 

Sorry to here about you having a bad ESC, those Sabertooth ESC's are usually very good, I've always had good results with them, that one might have been made on a Friday....lol.....sure you will get it figured out. Nice to see some paint on this build!!

:jaw::jaw: Nice Work, Looks Great.

Re: dresser TD40B dozer
 

What a Beast!!! Looking forward to seeing it perform in the dirt! :cool:

Re: dresser TD40B dozer
 

Looking very good Steve, all dozer project interesting to follow. Will for shure move dirt long before mine will.
Electrical drive is a must when building "smaller" model, wish I have done that from beginning. How long time will battery last when running?

Re: dresser TD40B dozer
 

Great looking dozer!! Really like that it's not another cat, something different for a change!! What year is that machine? Is there also a spring and plunger behind the grease track tensioner??
KP

Re: dresser TD40B dozer
 

This turned out really nice, it'll be great to see it in the dirt!

Re: dresser TD40B dozer
 

Thanks all .

Dan I cycled each side with no load without the sabertooth with a 11.1V lipo 2100MaH batts, I got 21-25 mins when batt got to 11.5V . I'll be running on a 18.5V 10900MaH lipo .

KP, yes spring behind grease ram a must . As for year, since I couldn't get the proper yellow, lets say the years of the Komatsu / Dresser merger . Right before they came out with the TD40C . Painted Komatsu yellow which Is the paint we got from the dealer to repaint my TD8E years ago . Cab interior should be tan, but the primer gray is close to komatsu's gray interior so I went with it :confused:.
