Re: 990 cat loader
 

WOW! That really came out nice!Although! I see you & Travis are useing the same wimpy axles. I gotta have a front row seat for the vid,Can't wait to see this monster get a good full bucket. Then watch the front of the machine go to the ground when you try to lift it.:eek::eek:
Gotta get one in there when I can.;)

well I could bench test them just give me a few min :rolleyes:

Re: 990 cat loader
 

what scale is this?

Re: 990 cat loader
 

14.5


Oh, freddy, bench test failed by IHB standards Axle redesign in order :rolleyes:

STEEL AXLE HOUSINGS!!!!!!

Re: 990 cat loader
 

Nice parts you made, never liked a Cat but i like your work so far! :)

How much does it weigh as of now?

Re: 990 cat loader
 

4 wheel motors. It'll leave the rear body open for hyd system & electronics. Not to mention much more power than you'll ever get from a motor/trans/axles and alot less mechanics involve.

Review Elliot's & Kalle's Fumotec adt builds for axle design & choice of motors.

Looking fantastic thus far, this one could definitely be a money maker for you... providing you alter it a bit so it isn't a Cat, just looks similar. ;)

Re: 990 cat loader
 

Looks great Steve! Ill take one:D:D

Re: 990 cat loader
 

Joe , if i sell , they will be unbranded . and yes talking to freddy , 4 gear motors ;)

Re: 990 cat loader
 

if you decide to make one to sell, let me know. I will buy one for sure

Re: 990 cat loader
 

Steve, I need an order form, better start making duplicate parts.

Re: 990 cat loader
 

Sorry but I completely disagree without 4 escs you have no way to make true 4wd. Not to mention price and how often they discontinue gear motors so if one quits you are now buying 4. "Not to mention much more power than you'll ever get from a motor/trans/axles and alot less mechanics involve."
Joe you have no idea of what he is using.:rolleyes:

Travis

Re: 990 cat loader
 

I've given this issue some thought :confused: tha housings definately need some up grade :rolleyes: it takes over the weight of my pans to bow these housings which is flatening the mammoth tires unfilled . 1 major faill point is the axle extension at the screw area not much meat for plastic :rolleyes: and they just look to spinly not big loader like so like my mack , I'll be making new housings ;) steel I think will be overkill . There is plenty of room to fit everything needed ;) + an operator in the cab .

Re: 990 cat loader
 

You're wrong on every point Travy.

My Komatsu is 4yrs old, I have done zero wrenching on it and it has moved several cu/yds of dirt in that time. That wdc I had with its overly complicated drivetrain, I had to split it twice to replace driveshafts. And those wdc ball shafts are a hellva alot more stout than the Tamiya dog bones/cups you're using in your loader.

I guess your idea will probably be fine for you b/c you only use your stuff sparingly in rubber dirt at a few shows a yr.

If Stevie has any plans to market this loader, then he better do it right or expect alot of negative feedback.

Motor/trans/driveshafts/axles = problems ...especially if this loader has any significant weight to it.

Re: 990 cat loader
 

:rolleyes: 1 power source 4 motors the motor that loses traction will spin and the others will stall out.

I have ran Izzys loader as well as many others with no problems and yes we do play with it in his yard which is a loamy sand a very heavy combination.

Maybe you should scratch build one and show us how its done.

Re: 990 cat loader
 

for sure it should be 4 drive motors. Alot simpler and smoother running with the weight of the machine. You would not need 4 seperate esc. They are alot out there the can run multi brushed motors. The Mamba max pro would be perfect.

Re: 990 cat loader
 

It is not a mater of one esc not being able to run them it is keeping equal power to them.

Travis

Re: 990 cat loader
 

At low throttle, yes the motor with the least traction will spin alone. At greater than half throttle all four motors go no matter which one has less traction. At full throttle the power is undoubtly equal to all of them.

So you play in the dirt occassionaly... have you even worn the paint off the tracks yet, much less the bucket? ...8 months later

What does Izzy figure he has for hrs on his loader in the dirt? I ran my wdc more than 250hrs for sure the 1st two yrs I had it and the Stahl would undoubtably get a 100hrs each yr, the front aluminum edge of the bucket is razor thin, I could probably shave with it, I'm gonna need a new bucket soon.

I don't have to scratchbuild my own to prove my point, all the top german companies do it with a motor at each wheel for the power, durability & reliability. wdc is the only bonehead that refuses to change, and their market share diminishes moreso every yr as ppl get wise to their models' lack of substance.
