thanks for looking

Re: 990 cat loader
 

I get goosebumps looking at this thing. Love the rear tire squat! What a beast!

Re: 990 cat loader
 

Looks great!

Re: 990 cat loader
 

The loader is looking great Steve, if your not careful it is going to weigh as mush as my dozer.

Re: 990 cat loader
 

woaw! truly amazed by this professional built. just wonder how you get to the drawings to steer the CNC machines. are this self made in cad? looks phenomenal!

Re: 990 cat loader
 

thanks Joe , heh heh :o I think it's getting close :eek: for some reason , I can't make anything light :confused:

aw , it's not that scary :p the rear tires just need some more air :p thanks Nate ;)

thanks Kerst


Thanks Cat , 1st it started as a pic from the sales brochure imported into auto-cad , scaled to 1:14 scale , many hrs. of tracing and tuning up the tracing . 2nd ,many hrs. of design of all the components as an assembly .
3rd , break the assembly into parts , duplicate where needed , place parts of same thickness on that certain thickness plate in such a way as to min. waste . keep in mind I'm doing all my designs in 2D :eek: . 4th import part plate file to cam , hrs. of programing ( for me any way ) , simulate to make sure everything is what you want (IMPORTANT) double check , triple check , maybe quad check :eek: . 5th, load file in machine and set up (IMPORTANT) double check , triple check , maybe quad check :eek: 6th , push green button and watch crunching action in blink of eye :eek::eek::mad::mad::mad: only if you DID NOT , double check , triple check , maybe quad check :eek:. As you can see this CNC thing has and still is a rough road for me yet :eek: I still like hand cranks , but , with what I can do on the VMC now , this CNC thing is catching on :D .

Re: 990 cat loader
 

:eek::eek::confused::confused: I think ill stick to styrene!! It amazes me still how you guys can take a picture and crank out a part that looks perfect like that!!! WOW!!! This loader is looking bad a$$!! :cool:

Re: 990 cat loader
 

A few pics of to days carnage :eek::o I made a bunch of brass shavings and a few parts :o (cylinders :D) not quite done :( ran outa day :( + the groving bar I made with major inferior material didn't werk :( so I gotta order 1 :rolleyes: Need to cut the ID seal grooves in the glands . I also got the front drive shaft hooked up last evening . I also remade the engine hood . the 1st was made from scrap panel from a delivery van which didn't bend to well without breaking ( not 6061 ) so I picked up a peice of .125" 6061 sheet and re ran it . No pics of the new 1 , forgot that pic :o .

Re: 990 cat loader - Hydraulic lift cylinders
 

IH,
can you show some detailed photos of the end seals for the rams you have made and give an indication of the physical size along with whether you had any issues with leaks etc. Love the build, looks awesome.

Cheers

Trackerman

Re: 990 cat loader
 

Oh, like that last picture, start with a big chunk of alu and a good CNC machine, minutes later a ready 990, ha ha.

The model looks realy good, have had a special eye on the big one since building the 992 over 30 years ago. Not so many projects on wheel loaders, maybee because of availibility of ready to run models.

What program are you using when drawing? Is it possible to get an description of the different steps involved from drawing to machined part?

Re: 990 cat loader
 

Nice to see someone getting work done. Now I can see a better view of what you texed me last week.

Re: 990 cat loader
 

Looks great!

Re: 990 cat loader
 

Nice work steve-looks like you are making some progress.

Re: 990 cat loader
 

http://i830.photobucket.com/albums/z...r/DSCN0149.jpg

WELL IF YOU GET PISSED ABOUT THIS MODEL IF THE SCALE IS OFF, JUST RAPID Z ONTO THE TOP:eek: AND SHORTEN IT SOME

Re: 990 cat loader
 

now thats a beautiful lookin 990 Steve! I should know, I work for a Cat dealership and as a matter of fact there is a 990 in our shop this very moment. Good loader, its been working at this mine for over 15 yrs now.... I did a complete rebuild of this machine twice now over the years....kinda funny, I wish I could build em but I just fix em. If you need any more measurements or pics, just let me know and I'll send ya what you need, I know this machine inside out.

Mario

Re: 990 cat loader
 

Here she is....

Re: 990 cat loader
 

thanks Mario :) 1 key problem area is the Z link :confused: I couldn't get good measurements off my scaled pic of all pin centers .I'm not a 100% sure I have it correct :confused: Looks like I should've punched vent holes in the hood too :o , looks like hood #3 in the future or a funky fixture to get hood #2 right . I kind of liked the 990G stacks instead of the stock year I went off like in the pic you have here . Thats a good pic of the fire suppression ;) , the 1st deck plate I put it right be hind the cab :confused: which I'm using to disguise the pressure relief valve . Also good cabin interior would be great ;) .

Re: 990 cat loader
 

I hope thumbnail pics work for now. I'm using my company laptop and I dont have photo bucket yet. We currently have the steer joystick apart and its not in the photos. I can get better pics of the Z arm once machine is back up and running. Currently have the bucket held back with a few wire cables just in case we have to pull it out of the shop. I took a quick measurement of the z arm... distance from center of top pin to center is 41 1/2" . Distance from bottom pin to center is 52".
Like I say, once she's up and running I'll get some better pics for ya.
I also sent the pics to my home computer and can send them to you from there when I get back at the end of the month.
Have a great day!
Mario

Re: 990 cat loader
 

I guess a 994 for your next project is out of the question ? lol . the thing would weigh a ton eh?

Re: 990 cat loader
 

I'll PM you my email then you can send the pics there Big help on the z already:) .I have the top center-center right but the bottom is too short . Looks like a new to be made :o the 1 I have is too short :( . It was the only part that was distorted from what I had to go by .

Re: 990 cat loader
 

I missed this 1 this morning :rolleyes: thou shalt not jest :D I doo know where to get that size tire :D BUT I have a few projects to finish 1st :eek:+ a few in line :eek:

took a little break before pulling the vise(make shift indexer :o) off the mill . milled up the steering cylinder bosses . I used the step block and clamp to hold my 0 position :o .

Re: 990 cat loader
 

Doesn't take you long to carve out parts anymore Steve.. must be a great level of satisfaction to do things quickly & correctly, eh? :)

Re: 990 cat loader
 

YES it does , Joe :D I love learning new things ;) before 3 years ago I never touched a mill in my life except for looking at them at the salvage yard / liquidater . I can't wait to get this going :D I also got 1 of my micro pumps figured out . to put in the pan ;) the Jung is just to big for it (very little space ) So If my cylinders work out I'll be making up the 1's for the pan and dozer sometime after indy .

Re: 990 cat loader
 

My pleasure Steve. Glad I could help with the Z arm. Looks good! Can't wait to see her running!

Re: 990 cat loader
 

Gidday Steve.

Hey Mate, can't offer any advise though I can add to the list of many readers who have praised you on your efforts.
What a fantastic looking model and to see it comming together is a trip in itself.

Totally impressed of what can be made with the "Can Do Attitude"

Can imagine what the guys that work on or operate this machine would be thinking.

Awsome craftmanship Steve.

Shane.

Re: 990 cat loader
 

yeah Shane, I work on this type of loader and what I think is " wow ! I wish I could build'em like Steve."
Seeing as I can't , I like to try and help people like him get the info he needs to continue his work of art....and thats what this machine is.... a work of art!

Mario

Re: 990 cat loader
 

Thanks Mario ;) , Shane

well we made it to Z bar #4 :eek: and what a !@#$ it was al the way :eek: Guess thats what I get for staying up till 4 in the AM a week ago gettin it right :eek: turns out the loader arms where too small too :mad: So remade them too and thanks too having a tig the whole loader arm assmb. got welded together ;) I still want to clean up the weld a lil better in the mill . I couldn't resist a lil paint on it either :o . made my Y's the old way drill press hand mill (file) and vise doo too both mills being setup for other ops . nuff BS here's some pics :o

I want to clean up my bucket a little more with the tig so gotta sand blast it . Pool noodle did the trick on the tires ;)

Re: 990 cat loader
 

Wow, Steve, that looks great!

Re: 990 cat loader
 

thanks Rob :)


ALMOST:D:D:D gotta figgure the mixing on the radidio and change out a leaky robbie valve head :( the tolorences on these things are pathetic , must be +/- .01 :eek: with a little tinkering you can get them to work right , except for the 1 where it leaked right out the rotor stem . they should be a running fit with no sidw to side play . I got bucket and steering werkin :D just waitin on the slow lathe guy to get my new rams for the lift cylinders done :rolleyes:

Re: 990 cat loader
 

werking!!!:D:D:o:o figured out the mixing just alittle reading of the manual :rolleyes:pump is on my aux1(flaps)chl . I got the steering so that when you activate the steer servo the pump runs about 50% to werk the boom/bucket put the pump switch in mid position for about 50% for guts , switch in 3rd pos. As for the valves , they're like a HD gotta tweek them when they're new and after so many mi /hrs :eek::p

Re: 990 cat loader (WERKING)
 

Way to go Steve, it can be quite frustrating I know. It makes it all worth it when it comes alive though. WOOHOO Now video please!!!!

Re: 990 cat loader (WERKING)
 

will do Ben In the pea gravel too ;):rolleyes::D

Re: 990 cat loader (WERKING)
 

Man Steve that looks great!!! youve done an awesome job with it so far!

Re: 990 cat loader (WERKING)
 

thanks Aaron

to answer Mario's ? from the trailer build . I was digging pea gravel well except for the mixing thing with the radio . the pump would always go down to the steering settings and wouldn't have the hair to pick up a full bucket . So I just put the pump full on or full off :D then moved the coal pile twice till I blew the clipard cylinder I used for steering well It was leaking right off the bat but desided to leak alot more :confused: no vid :o will get 1 soon I hope :o right now I'm trying to make new steer cylinders and my own spool type valve . I hate these robbies :eek: it's not the style I hate just the tolerances are piss poor . you tighten them to eliminate the bypassing then you can't turn them :eek:. I had brass bushings (not oil lite )that I made for my axle shafts while waiting for bearings , well they started to sieze up :rolleyes:so in went the bearings . easiest set of axles I worked on to date ;)not to mention tough as carbide , so to speak :D

Re: 990 cat loader (WERKING)
 

Thanks for the update Steve, very nice of you..........oooops, have I struck a cord of frustration? Hydraulics causing grief ?... Welcome to my world of fixing....not building :)
there is no doubt you will figure it out.

Can't wait to see more!.......

Mario

Re: 990 cat loader (WERKING)
 

Wow that model is built like a tank! Great build keep it up!!!

Re: 990 cat loader (WERKING)
 

yea they're fustrating but heck , with the few leaks and no bosses on the boom , I can't resist useing up a battery in the pea gravel we put down in the play area for the kids :rolleyes:. I'll get a vid up someday :o I gotta figure out how to take 1 on the new cam :o I'm may start painting it soon .

thanks much , it wieghs like 1 too :eek:

Re: 990 cat loader (WORKING)
 

it is cool when the equipment starts moving and twitching makes it fun and frusterating but it is worth it nice work steve........Izzy and Travis helped me on the D 7 but it is in peices right now ......a later story.... Can't wait to see a video and have fun digging and loading trucks

Re: 990 cat loader (WORKING)
 

thanks henry I tinkered on after I ran it last night made a few small things that I could do while waiting to change parts on the mill . I got another 30 mins in tonight . 1st night with no leaks :eek::D and 20 bar . I still got little odds and ends like better linkages for the valves to see If I can get better control . vid is uploading verrrryyyyy ssssssllllllllloooooowwwwwwwlllllllllllllllyyyyyyy :(
