cat 933 brake's

[winmac]

Hi, I've got a 933g (turbo,std,shuttle shift, electric start) that desperatly needs brakes. I have adjusted them to the max several years ago. I do rember standing on my head to adjust them and thinking what a horrible job it would be to replace, No way around it now it needs new bands.
I was hoping somone could breifly describe the best dissasembly procdure to get at these.

thank you
winston

You need to removed the complete final drive for changing the brake band on 933 CAT.

I've read on another thred here that its possible to change the band thru the acceses hole, I'm doubtfull. Hopefully someone here could shed some light on that idea.

Is it necessary to remove the rear loader frame to pull the final drives?

Mine was an F, yours may be different.

Now lives in Peru, but the brake bands came out an access plate under the tractor, in pieces. Very easy to get to, nothing else to remove but the plate. I'm remembering 3 parts to the band, that bolted together once you had them in place. Sounds much worse that it was. If your drive's leaking, you'll get oil when you remove the plate so remove the plug in the plate first.

I had a similar situation with mine, difficult to adjust further so I figured the lining was too thin. Called my Cat dealer who had no idea how thick a new one was, the parts guy said to order the linings and when they came in look at them and if they weren't a lot thicker, leave them there.

Struck me as a poor way to do things so I asked corporate Cat. Got a nice response, but the guy discovered he didn't have the necessary security clearance to get the information. SECURITY CLEARANCE? For brake linings on a 45 yo tractor? The next day he'd found someone with clearance, turned out my linings had worn only 1/32". The adjustment threads were in poor shape.

Nothing replaced several years later, when it went into a container for Peru. I did shim the adjustment nut up higher. You probably want to do that. Unfortunately for you, my manuals and notes went to Peru.

You need a manual and parts book, check ebay. Also, if you don't have an owner's manual with a grease chart, you're probably missing grease points in the front. Unless your tractor, unlike mine, came with an attached lubrication chart.

Great old tractor, but there's a real interesting pair of bearings in the transmission that I hope you never need to buy. Gotta go direct to Timken for them now, and your Timken dealer won't have a clue as they were only sold to Cat.

Good luck.

Forgot to mention I once went under another 933 that was missing the lower access plate, just a gaping hole. Apparently some nitwit tired of going down there to let the leaked oil out and rather than simply removing the plugs, removed the whole cast plate.

Peru???? now that was a big move Tom. Hope all is well down there.

Hi Bob, nothing I planned. Sometimes when you advertise on craigslist odd things happen.

Had two buyers, but one was from an extremely expensive area near Washington DC. Made no sense that he'd want that old a tractor if he had enough money for land there. He didn't. It was bought to replace the 2 yr old very expensive road to the ancestral farm in Peru that washed out in a 100 yr flood last year.

Would you believe $17k shipping? I did point out that they were shopping on the wrong coast, had to go through the Panama Canal from here. They also bought the trailer I'd used to move it.

So one Sunday evening on top of my mountain they were taking little movies of me operating it. Sent via cell phone to Peru, where somebody asked me to do various things. No idea if anybody there knew much, the guy I dealt with didn't, wasn't about to try driving it. Told him that if they'd buy me a plane ticket I'd go down to operate it awhile.

Since then, a hauler buddy here has moved several other tractors for him headed to Peru, mostly skidsteer. Must be old machinery is worth a whole lot there. I was happy to get $7500 for the 933, a nice profit after I used it professionally for several years. Photo above is on a job. Replaced with a similar age 944 that suits me much better.

WoW, that's a Job Tom. Nice work if you can get it.
Trust you will be coming home to Va again then Tom?

Oops, my apologies Bob.

I'm not even managing English very well it seems. No Spanish at all. The only thing that left Va was the 933 and trailer. I'm still here on my mountain, watching the snow fall. Which means it must be summer in Peru, now that I think about it. They haven't yet bought me a plane ticket. Unlikely.

Did have a guy ask this morning if I might be interested in building a house like mine in southern Mexico, but that's got nothing to do with tractors. I live in a somewhat famous small underground house, get those sorts of offers about 4 times/year.

I talk with everybody, you never know where it might lead. Like that excavation job, which had a couple of rocks a little too large for the 933. Above is the 944 hiding behind one, before I had time to put a widow-maker canopy on her. I'm not real small, that's a big rock. Love those 944 hydraulics.

Remember Aussie Deas Plant? He guided me to find the right tractor for my needs. No accident that I got one that is NOT articulated. Came out of a gravel pit, the seller couldn't believe I bought it for mountain use. It's fantastic. I knew what I wanted to do, needed someone with a lot of tractor experience to point me in the right direction. Deas was great.

Yes Tom, Deas is half a world away with two worlds of experiance. Glad to hear you are still safe and warm way up on the mountian.

Acording to the parts book my linings are made in thee peices so I should be able to remove them as you described. The nut is completly down to the bottem of the thread, since the machine is seldom used so I may try shimming it first. Hasn't been a bad machine so far just a bit akward to operate, I was working it today clearing stumps and managed to burst a hose.

 

[bob plumadore]

I can scan and send you the pages from the service manual.be careful of shimming under the nut. there is a reason you run out of adjustment, if it wears to much you will have to pull t down and replace the brake drum. I think this will let you E mail me so I can scan pages to you
I stil have 933 manual that was never put in binder. what is your SN, I may still have parts book

 

[VaTom]

Hope it wasn't one of the primary hoses in the guts of the tractor. There's one down there that I had to use a come-along to bend into place. One end cost almost $100.

Nut bottoming out sounds like you're due for new parts. You can feel for lining when you're under the tractor, obviously needs to be some space between band and drum when the brake's applied. You'll find it's a pretty easy replacement. Now that I think about it, there's an adjustment stud on the bottom that needs to be correct to make the lining wear evenly. I don't guess it's been checked recently.

Like most things, the second side was 3x faster than the first. Brake adjustment's not anything I'll miss about my old tractor. Your hands stay real busy operating, but it never bothered me.

BTW, that excavation customer thought the world of my 933 when he saw what it could do. He even gave me a $1000 bonus. He'd had trouble finding anyone willing to take on those rocks, more than a few of them. Wasn't happy when I told him I sold it. He's now living there, at 81 finally achieved a 40 yr dream for the property. I left him 25' deep fill for his front yard, kinda steep side of a mountain.

 

[winmac]

Thank you for the offer, I do have the parts and owners manual that shows all of the adjustments and set up. I will inspect the linings before trying to shim the nut.
Right now that machine is down with a busted hose, I just spend 45mins at cat, there is one flange end that they cannot find. the current plan is to cut out the old end and try to re-use it, hate to scrap the machine for a bad hose.

 

[VaTom]

I never had a problem with Cat and hose ends, but I ran into other parts no longer available. Sometimes an internet search works. Sometimes not, my 933 left the country with a custom reverser gear in it.

A Cat part search was how I stumbled across a company in Tennessee that offered me a new transmission shaft amazingly inexpensively. Why did they have one and Cat didn't? Turns out their business is buying whatever was in a warehouse, no matter how deep the dust was. They knew they were offering it about half Cat price. Also were well aware there wouldn't be many customers for one. They use Cat part numbers to identify, know what they have in stock.

Good luck.
