CAT 988F Series II Wheel Loader
 

I have wanted a Wheel Loader for some time now so I decided to try my hand at building one. I have the tracked loader but I wanted some thing to load a little faster and have more reach so I decided to go with the 988 in 1/14 scale.

Here is what I am attempting to build.

Here is what I have so far. The Mammoth tires are the right size for this build in 1/14 scale so now I am waiting on the rim builder to make my new one's.:D

I have had electronics in it and ran it around the garage. So far it seams like it will have plenty of power now I just have to make it look like some thing.

Thanks for looking.

"so now I am waiting on the rim builder to make my new one's"

O so blame the wheel man , eeh :rolleyes::eek: Looks good looks like it should load the mack OK

Re: CAT 988F Series II Wheel Loader
 

You have been growing with ingenuity and complexity with each build Travis. Really looks nice, made your own transfer case out of delrin I see.?.? It's nice to see it come alive after the discussion in Indy. Keep it up, I'm sure I'll steal some ideas for my next complex machinery build. That poor guy in a cage PA is everyone's friend, he just can't say no,can he?

Thanks Ben and and you are right Steve does have a hard time saying no.

I am noticing in my pics I have the frame to high on the front axle so in the morning I will disassemble it and machine it down some to make the frame sit level. Funny how you notice things more when you look at it in a pic.

I also got my order from Micro Mark today, new vice, clamp set, and true inch conversion for the mill. They were out of stock on the R8 Collet set but I will be getting that as soon as it is back in stock as well as smaller tool makers vice.

Hey Travis, look's like a fun project! Keep us posted! Like the T-Case.

Steve, Aren't you looking for a new coal shovel? LOL!

Re: CAT 988F Series II Wheel Loader
 

I like these older Cats. The cabs are neat, with the triangle windows.

That's an interesting drivetrain and frame. So you've got what looks like Axial axles, but you made one with a pass through input/output shaft, and you are using that as the mounts to allow for axle oscillation? That's actually a pretty cool idea. I don't think I would have thought of something like that. How's it work? Just a couple bronze/oilite bushings on the input/output shafts to allow oscillation? Kind of surprised there is enough shaft left to hook up the driveshaft yoke.

Re: CAT 988F Series II Wheel Loader
 

I love it , excellant drive train work , I am in awe ! !

Re: CAT 988F Series II Wheel Loader
 

Thanks Neil I just hope it works when I am done.


Thanks I had to come up with something different to get it all to fit and work.

Nate you are right they are Axial axles and the shaft was to short. The good thing about these axles is that they use a pin drive pinion so I just made a longer shaft to make room for the pivot. The other side is a Traxxas Stampede front axle shaft, I didn't need an output or input just a pivot point.

Thanks to all for looking.

Re: CAT 988F Series II Wheel Loader
 

I was just wondering what the dimensions are on those tires?

Thanks Reg

Re: CAT 988F Series II Wheel Loader
 

very nice work i can dig that lol i also think aluminum axels would be a good idea for a lil weight and strength for pickin up those heavy loads of dirt or crushed rubber very cool good start can't wait to see more

Re: CAT 988F Series II Wheel Loader
 

Cool project Travis and nice start.

Great idea on the large size too because it is easier to load everything.

Re: CAT 988F Series II Wheel Loader
 

Nice choice on the loader Trav. I think your going to enjoy scratch building equipment more than trucks and trailers. There is more challenges because you can't just buy the parts you need, you most build them.

Re: CAT 988F Series II Wheel Loader
 

I still like building trucks and I have made the trucks more complicated these days as well. Don't worry though I am collecting parts for a dozer as well and so far I have the tracks, gearmotors, and ESC, not much but a start but I am getting there. I am also working on getting the funds for one of the excavators RC4WD is selling.

Re: CAT 988F Series II Wheel Loader
 

Hi Travis,

Excellent start... it looks fairly capable in the video too, near the end it went up the step very easy. Looking forward to seeing this is progress.

Elliot

Re: CAT 988F Series II Wheel Loader
 

Very good, Travis! Are you going with hydraulics for the work equipment, or going to surprize us with something new - ceramic magnet cylinders or nano-technology gearmotors? :p:rolleyes: Anyway, very cool beginning.

Ken

Re: CAT 988F Series II Wheel Loader
 

Thanks Ken I have some hyd alternative ideas but we will have to see how they work out.

Travis

Re: CAT 988F Series II Wheel Loader
 

This is a very ambitious build Trav, but if anyone can do it you can! I'm staying tuned for this one.

Brian

Re: CAT 988F Series II Wheel Loader
 

Travis, glad to see you are joing the "over-sized" club too.....:D, greal build! You know i will be following this.

Re: CAT 988F Series II Wheel Loader
 

Wow thats cool! Is it going to be hydraulic or screw drive?

Re: CAT 988F Series II Wheel Loader
 

It's always fun driving around a bare bones chassis, isn't it? Something about seeing it move under it's own power for the first time. Cool.

Re: CAT 988F Series II Wheel Loader
 

Nice one looks good in the video cant wait to see some more pictures.

Re: CAT 988F Series II Wheel Loader
 

Hey Travis, do you need to see the kyosho hanomag manual, for screw drive idea's???
Let me know, I can scan it and pm it to you?
Keep up the great work. Later, Neil#2 aka doodlebug.

Re: CAT 988F Series II Wheel Loader
 

That would be great I am always up for some new ideas.

Travis

Re: CAT 988F Series II Wheel Loader
 

Look'in GOOD Travis!! You're going to tax the **** out of your lowboy to get this guy to the job site! Keep us posted.

-Terry

Re: CAT 988F Series II Wheel Loader
 

I like the chassis - sturdy, simple and straight forward

Re: CAT 988F Series II Wheel Loader
 

Hey Travis, PM'd and emailed the manual to you. Hope this help's!
Later, Neil#2 aka doodlebug.

Re: CAT 988F Series II Wheel Loader
 

Great job Travis ..simple and works well..wish I could build that quick..gona keep tabs on this one...

Re: CAT 988F Series II Wheel Loader
 

Cool cant wait to see more pics and a final product!

Re: CAT 988F Series II Wheel Loader
 

Is it done yet?

Re: CAT 988F Series II Wheel Loader
 

No :eek: he's waiting on the wheel guy :rolleyes::p who is secretly holding him back till he can catch up :D:D:D:p:p:p:p :eek::eek::eek:

Re: CAT 988F Series II Wheel Loader
 

Well you had better get busy I got a little more done today.:D Just a small update but here are a couple pic's.

Re: CAT 988F Series II Wheel Loader
 

Travis - get on your wheel guy - those current rims are ground on me - sorta like a hot wheels version of a 'cat. LOL


Chris

Re: CAT 988F Series II Wheel Loader
 

This is comimg along nicely. Are the lift arms 1/4'' plate?

Re: CAT 988F Series II Wheel Loader
 

Yes they are.:D In 1/14 scale that is only a 3.5in wide arm. I want to be sure this thing will hold up over time.

Travis

Re: CAT 988F Series II Wheel Loader
 

It will hold up and also look good. Some people don't use heavy enough material and it just don't look right. But if I know you this thing will look and perform great.

Re: CAT 988F Series II Wheel Loader
 

Great work Travis
I have been too busy at work and have not kept up with all the action on this thread. I think work will slow now and I can spend more time watching your build, keep the updates coming.

Re: CAT 988F Series II Wheel Loader
 

looks good can't wait to see this loader in action

Re: CAT 988F Series II Wheel Loader
 

Just an idea travis... why not make some templates, you get the idea:D
