Cat 212 Grader Scraping Topsoil and Spreading Gravel

Hey Sasquatch,

Good job with laying out the gravel... :first:

You've done well
You can never have to many sheds, at least thats what my dad always says

Paul

nice work is this going to be a Cat shed ? keep up the good work.

Very nice. The 212 is a good size for lots of jobs. I was very impressed with ours' ability to lug and pull through a tough spot.

Are the super single rears a stock wheel or a custom build? They look to be very effective.

Isn't it cool that when our hobby toys can justify there existence? Nice video Toby. Tell Ted he makes a good star.

ccjersey, the single rear drive on this one is indeed an all Cat factory setup, it's just not as common on this era of grader as the tandem drive rears. From studying the parts book it's apparent that the single drive graders use a different rear axle housing than the tandem ones since they need no pivoting attachment hub for any chain cases. Instead, the axle housing ends just have a solid flange that the bearing/axle seal retainer bolts to, along with the brake backing plate.

According to the parts manual all the major brake components (backing plates, shoes, drums, wheel cylinders, master cylinder) are the same between the single and tandem drive rear ends on this model, the main difference is the single drive brakes have solid brake lines feeding the wheel cylinders and the tandem drives use a short section of brake hose because of the pivoting of the chain cases.


We ran all new brake lines too -

Also had to replace the master cylinder due to excessive pitting inside the bore, still was able to pick up a new one at the parts store -

Finished up with making a couple of step plates to protect the new brake lines where they route on top of the axle housings, it was apparent that the old ones had been mashed quite flat from "foot traffic" in the past. I made them out of some scrap pieces of steel channel I had laying around.

We put DOT 5 brake fluid in too because it's non hygroscopic and considering as much as this grader sits around, water contamination was a concern. The system bled out just fine with the DOT 5 and the brakes work great.

Roger, I'll let him know for you. He did comment something to the effect that I would make a good paparazzi, the way I was hounding him with the camera.😛hoto:

[quote="janmeermans"]Sasquatch,

Your dad did a good job and you did very well with the camera. I hope you had a tripod mount for the shots backward from the steering axle and you weren't standing on the frame, ha!

I kept waiting to see the "can opener gash" on the steel siding from the top of the blade corner but alas, it did not happen. Don't ask me why I would be looking for that!

Jan, once of the nice things about those little GoPro type cameras is that there is a large selection of accessory mounts you can get for them, so you can attach them to a lot of things and just let the camera record. About the handiest tool I've found yet though is a regular pipe clamp that I put anywhere it'll fit and mount the camera somewhere on the round pipe, sometimes gets a little wobbly but gets better angles because of the distance.
