(no parts engine or tranny ) We only need a maintainer once or twice a year for a day or two so this machine would suffice. It comes with a parts control box, power steering system and tandems. Needs tires as they are dry rotted, rest of machine is rusty but functional. Caterpillar has been paving the way when it comes to innovative motor grader Posted 00:48 (#4044345) Subject: Cat 12 motor grader '99' seriesSon has a buddy with a Cat 12 '99' for sale. Motor graders are indispensable pieces of equipment for road construction and maintenance, as well as any application where creating a smooth, flat surface is required.

Model 12 Cat Grader Parts How To Look Them

Our dealer has a cd with all the old stuff on it and its identical to my book except digital. I found one there for mine and it really helps when ordering parts. Parts books are on ebay all the time. Finding a parts guy that knows how to look them up is the hard part. Every part we've needed has been available at Cat. Does anyone have one of these 'classics' and can you tell me how hard are parts to come by? Anyone have a guess as to fair value? How does the 99 compare to the 'E'? The two machines should bring $3K+ across the scale at the junk yard.Posted 07:24 (#4044532 - in reply to #4044345) Subject: RE: Cat 12 motor grader '99' seriesWe have a 8T 12.

Can do so much more with it than a tractor blade. Pretty sure they said Cat Classic was a outside parts vendor not owned by Cat but either way the part was identical to the old one and fit perfectly.We use ours every few weeks. Every part was available next day except for that housing which came from 'Cat Classic' and took an extra day. Finally got time to tear into it and saw that it wasn't as bad as we thought but in tearing it down we broke a cast housing inside the transmission.

Bought a used crank and got new bearings for it, had the pistons and rods checked at a machine shop. Got it home and pulled the engine. Mine has 13.00x24 and the later ones have 14.00's on them.I gave $1200 for it at an auction but it was knocking. $150 a piece, tire and rim ready to bolt on. Every so often they have been getting in old graders and I lucked up and found a few good tires on them.

It does have a scarifier, no hydraulic side shift and a cab. He's asking $6K with the extra parts.

I'd say a good running 12 is worth $5000 easy and more if the chain boxes and controls are decently tight.

Interesting design in that the grader oil clutches use the engine oil (has a special oil pump with a separate section to feed the clutch ) which flows through the clutch and then is slung by flywheel and gravity flows back to oil pan of engine. The CAT oil clutch was actually introduced in the 8T series in the mid to late 1950's and continued through the 70/71D series with the old D318 before the D333 was introduced in late 1959 or 1960. Main differences are the engine is a D333 instead of a D318 and the clutch is an oil lubricated type. There were some other serial numbers used for 12E graders manufactured around the world, but in the USA, the 99E is most common.The E is just an evolution of the earlier graders. LOLPosted 10:15 (#4044958 - in reply to #4044345) Subject: RE: Cat 12 motor grader '99' seriesThe 99E series is the 12E. Has had some recent engine work (head ) and really leak free, only some minor 'seeps'.Now I just need approval from the Bureau of Expenditures, i.e.

There are probably many parts which are NLA from CAT, but there are usually ways to get used (ask your CAT dealer to find if you don't know a source ).If it has a pony motor start, the ponies on those were called ' buzz bombs' for a reason. The 333 in the grader doesn't have (or need ) a rear main seal either.Probably the most expensive and scarce part on the grader would be the head on the engine. The old D318 had no rear main seal, only a screw thread on the crankshaft to keep most of the oil in the engine, so an oily clutch was almost a given and happened quite often if someone neglected to drain the clutch housing regularly on the older dry clutch models before 8T16361 in 1955.

The 25' would likely be cheaper as they are a newer design, used on a lot of different later machines.

I had already had the crank in the grader reground and bought all the bearings before before I found the 'parts' engine to get some other stuff off of. Even got some engine parts (but no head ) including a standard crankshaft.

Would have been easier to change the tire with the rim mounted on the hub, but we finally put a jack between the frame and the rim, jacked it up tight, let it back off, spun the wheel (have to have ALL 4 tires off the ground to spin one ) and jacked again several times before it came loose.Most of the old graders don't have working brakes, other than the 12' wide one under the middle, and the rear hubs must be pulled to get to the wheel cylinders and shoes, so that takes a pretty good puller to pop them off and press them back on at 20-25 tons ( dry ! ). Then figure in the cost to change them if you will do it yourself and double that figure before you total up the cost of the new tires! I have spent a lot of time just getting a wheel off the hub and onto the ground to change a tire. Price a set of tires if you really have to get some before it is usable.

Before buying, look at the grader from the rear and notice whether the tandem drive housings or any one wheel splays out at the bottom. It's important to press them on properly, simply tightening the big nut up on the outside won't do it. Not a lot of trouble even though at that time, I was clinching the rivets with a center punch and a hammer instead of a real rivet punch like we have now.If someone has worked on the brakes etc and has not pressed the wheel hubs back on properly, they can easily work loose and wallow out the hub and damage the spindle. It was a plain sheet of material and I clamped it in place with visegrips and then drilled and counersunk the rivet holes by starting at one end and working my way along the lining to the other end. If you need brake shoes relined, I purchased the lining material from Automotive Friction in Birmingham along with the rivets and fixed one of mine that the lining had just fallen apart on.

I don't have a reason to doubt his assessment of the quality of the mechanical on the machine.I'll have to start beating the bushes for a good deal on some tires to see if I can make it work. It is an electric start 24V, and the head has been checked out by a machine shop when the head gasket went to leaking. Probably easier to just put on new chains if they are that slack.A couple of good forums you might be interested in are ACMOC Posted 19:17 (#4045838 - in reply to #4045368) Subject: RE: Cat 12 motor grader '99' seriesThe tires are 14-24's, were 13's, been changed. There is some adjustment on the spindles which will allow them to be rotated in the housing to move the spindle and tension the chains. Would be nice to see that it has been greased a time or two over the life of the machine! Also a good idea to look inside the tandem chain cases to see how slack the chains are, if they are so slack they can get a link balled up, that can cause some damage in a hurry.
