What engine is in my Model D grader? With pitchurz

[Bob Bancroft]

Here's some pics as req. Please note the sleeve and the o-ring on top. I've not done a sleeve and piston repl on these engines before. The box of stuff I got with the burn grader had four sleeves and pistons and a box of rings, and o-rings. I'm guessing that those o-rings will go somewhere, and when I get the old stuff off, I will know where they go. Not sure I have a full set of o-rings, if not I'll get some more.

First grader up I'll call the 'little D' as it has no scarifier, dual range trans, PS, hyd turntable, leaning wheels and the small tires. The propane tank of a D17 is just over the name of the grader.

The burnt unit actually runs, but burns a little oil. I didn't get much pics of the big unit with the Gleaner engine today as it's back in the rear of the shop and it's dark. Two pics of the blue Gleaner engine. I'll try to get some later.

I also have a S1 D17 with a good propane engine. I'm considering putting the propane engine from the D17 into the burnt unit. I have 9x20 good tires and rims for that and it has more features that will make a better grader when done. I can also have it over to the sand blaster shop when the burn engine is out and get it cleaned up for repaint. Note the rear hub weights. Fill the rear tires with fluid, and with those weights, and the dual range trans, it should cut ground quite well. Also has PS and leaning.

"A picture is worth a thousand words." Indeed. Thanks for the pictures.

The O rings go in the grooves at the bottom of the liners and seal the oil in the crankcase from the coolant in the water jacket. Clean the block well in the O ring area and smooth it so the O rings will not be damaged when you slide the liners in with some grease, soap, or some such lube. At the top again clean the block well where the liners sit in it and try the liners with no O rings before final installation. They should fit easily and protrude slightly above the block at the top. The WD, WD45 manual I have says the liners should protrude .002 to .004" above the block surface. This to help seal the block-head-liner-head gasket.

Looks like a plan. I'll clean everything up before I drop the sleeves. Some of them had been sitting outside for a while, and got some light oxidation and a bit of rust on the inside liner. I rented a hone and re-honed all four. A few pistons had some transfer rust too and I took that off with 1500 grit wet and a bit of soap. I'll put the seals in with grease and make sure it's all clean first.

I'm going to order a full gasket kit for the WD-45, do the liners, pistons, wrist pins, maybe the bottom rod bearings, have the head cleaned up and stuff it all back together. This spring should be moving dirt.

Sounds good hope all goes well. Just wondering, how did you end up with several graders? Always liked road graders and especially the AC ones like you have.

Serendipity. I was driving in the country a few/10 years ago and saw a sign on one of them with a phone number. He was just getting rid of it, as it had no engine. I tested getting it on my trailer and grabbed it up. The second one I found on CL for a song. The burn unit I just bought on facebook mainly for the running engine. I did get wheels and tires with it, but I wanted the engine.

The Gallion I found through the RR museum in CO, they had a link to the grader and it's going back to CO after refurb as I have a long driveway that gets plenty of snow. I'll be using the Gallion for winter duty in CO near Pikes Peak. I also might put a 'driveway' sign on it and do some other folks driveways for fun and profit.

There's yet one more model D in TX that's for sale but the guy wants $3000. If he gets it below $2000 I might go grab it up.

I worked on a lot of CAT 12E and some 12D and F models. I always preferred them over the Gallion graders.

CAT 12 series was the standard of graders early on when the converted tractor types fell out of favor. The real downside of the CAT early units was the non-hyd blade control 'knuckle buster' setup. They work great, and then they don't and when worn out usually aren't repaired right. Hyd required a lot less maint than the disk and clutch type on CAT units early like the 12.

New gears that the clutch dogs that are not rounded off, new horseshoes and springs,,,,good as new. Most of the gear box problems was the operator fully engaging the lever and letting it slip over in the box, then they would bust your palm when the edges got worn down. The problem with the older Gallions was all the cheap metal line vibrating and wearing holes into them. The Hi/Lo in the transmissions where prone to problems as well.
