Re: 990 cat loader
 

I spent about 2 years in an B model in another five years in a 992 G .that is amazing work and i had a real hard time telling that it was a model until I saw that the right picture :jaw:

Re: 990 cat loader
 

Did you get the rear lightened up and tires fixed?

Re: 990 cat loader
 

Steve, no I like to keep the weight :D but I'm thinking of doing what Reg did with his KW .
I had the cab ready for paint last night before I hit the hay so I got Earl out for a $99.95 paint job :bounce::rolleyes: , Now to see if I can get the best winders butcher to do the winders :rolleyes: . well here she is :o:o:o

Re: 990 cat loader
 

on a side note : those who where @ cabin fever saw this roll down the side of the pile after Scott distracted me while working on top the high wall :rolleyes:. Any how notice the FWD slant in the ROPs . I thought it look a little bit more then what it originally had :rolleyes: So took a closer look , sure enough it bent on the roll over :eek:

Re: 990 cat loader
 

Looks good Steve!

Re: 990 cat loader
 

Hello Steve did Earl run out of paint I see he forgot to paint the fenders? Ed

Re: 990 cat loader
 

yea like I said $99.95 :p

Re: 990 cat loader
 

Steve is just too dam cheep to do it all.

Re: 990 cat loader
 

With the roll-over, you need to have the ROPS replaced in order to stay "legal". Somewhere, I saw a scale-sized OSHA/MSHA inspector lurking around, just waiting to nail you with a citation! But, you might be exempt since there is no operator in the cab.?.?

I really appreciate the self-made hydraulic components on this machine - great job!

At our Brownsville,PA show,
A bystander who knew MSHA rules commented to me that our haul roads needed a berm:cop:. Later we found that true when one of Smallhaul's dump trucks took a trip over the side LOL.:lol:

Yah I like this one, except the loader scene!
Cheer's, Neil.

Re: 990 cat loader
 

steve you should have gone to maaco they would have done it for 59.95

Re: 990 cat loader
 

Steve, it's an amazing job you did! I'm looking to buy a such construction machine for a while, but you greatly inspired me, and now i'm seriously thinking about building a such machine like yours. I read through the whole thread but didn't find anything about wheels of that size. May i ask, where can we get them?

Re: 990 cat loader
 

Hi , Abel ,thank you :) The tires are from the tamiya mammoth dump truck which is no longer in production . Do to that they're getting hard to find . I have a mold drawn up ready to machine to make my own (when i get to it :() 90% of the machine is self made including the wheels .

Re: 990 cat loader
 

Thanks for the quick reply! I'm also investigating how a self molded tire can be made. I can't wait to see your's finished:)

Re: 990 cat loader
 

Steve, can you share some info about the gear motors?
First: as i read in most of the gear motor specifications, if the output shaft is blocked, it can damage the gears. Let's assume, that the shaft is never blocked cause it have enough power to drive the big wheel, but what happens if you turn (left or right) while the machine is not moving, are the wheels turning as expected, or are they still and sliding on the floor? (hope you can understand what i mean).
Secondly can the wheels turned by hand (slowly ofcourse), or could this also damage the gears?
(the 2 questions are the same, i know:))

I know this mostly depends on the gear ratio you're using, as i calculated, to get the max speed (1:1 -> 22 km/h, 1:14,5 -> 1,5 km/h), a max output of 50 rpm is needed. So i think, the best is a lower rmp motor as base to get the lowest gear ratio possible...

Re: 990 cat loader
 

Abel , I didn't go with the 4 gear motor set up in the end . Even they where to flimsy for the size and weight Of the machine . I went with a differential set up which seems to be holding up quite well :) I don't have any experience on using a gear motor at each wheel yet :o

Re: 990 cat loader
 

Steve, ok thanks, i thought you've tried it... For some reason i don't trust these gear motors either...

Re: 990 cat loader
 

parabéns perfeito

Re: 990 cat loader
 

What ? please write in English .

Also this is the 2nd thread of mine you post this in , what do you mean :confused:

Re: 990 cat loader
 

Hi again.

In the last 2 month, i collected a huge number of Cat blueprints, with aid of these documents, i built a 3D model in 1:14,5 with every little details - Some of the inside mechanics are still missing, but they will be done shortly.

Steve, before going further i will make a new thread for it, but if you don't mind, i share the results here: https://www.behance.net/wip/316985/659439

Re: 990 cat loader
 

Nice loader looks like a mean digger. I like the weight.

Re: 990 cat loader
 

finally got the proper lift hight :eek: and no more bolts for pins :cool:

went from just getting over the sides on the mack (11") to getting 16" :)

Re: 990 cat loader
 

Always great to see the 990 progress. The pins and locks look spot on Steve.
I think the broken keeper is perfect! I look at a pin like that it tells me, that one went dry seized in the bearing and the pin tore the lock off and was repositioned after repair.:p:D...another touch of realism;)

Re: 990 cat loader
 

Great job Steve looks real good. Ed

Re: 990 cat loader
 

That's great way to make those pins!!! I've been thinking on how to do such. Sometime in future I'm going to use your idea and get rid of the c-clips I'm using on pins. I tried to make the flats undersized and press pins into but just not enough material to make tight enough and reliable. And loader looks great!!!

Re: 990 cat loader
 

The pins came out nice and the loaders looking better all the time, but what I really like is the jig you made to mill the pins! Nice job! Sometimes the set ups harder than actually making the part.

Re: 990 cat loader
 

[QUOTE=ihbuilder;108228]man what a ##### :eek: the lil keepers
Just wait a few years when you can't see and your hands are shaky and then try the little parts. :D Hopefully it won't happen to you but enjoy things while you can. Nice touch on the detailing of the small parts. These things make a model.

Re: 990 cat loader
 

Steve,

Nice detail!!! I agree, normally it takes longer to setup a part than run it.

Re: 990 cat loader
 

Great work on those pins, Steve! 16" of reach makes this Cat a monster!

Re: 990 cat loader
 

nice build but noticed u steal haven't done the up grade to the tires barn hausen modellbau might be a good answer he has a large selection

Re: 990 cat loader
 

I have some on order since Christmas from RCM which I think barnhausen makes them for RCM, not a werd yet :( . I tried Barnhausen directly with no reply . I was hoping to have them for this week end :( There was only 1 size I saw that was close .

Re: 990 cat loader
 

So what's the bore size of your new lift cyls?

Re: 990 cat loader
 

0.625"

Re: 990 cat loader
 

holy jeepers looks like I'll get new tires after all :jaw::jaw::eek::eek::cool:
