New here,need help with id this crawler

Eric N · February 12, 2009, 10:33:14 PM

New the the crawler stuff. So far my experence has been with Oliver tractors and different brands of skid steers. The plate on left side of engine has 6351316 TC and FXH 008. I'm working on getting a pic posted as soon as I figure this stuff out. Looked on the bellhousing like one of the post said it might be but nothing there. Thanks,Eric

Is this crawler a 3, 4 or 6 cylinder? Gas or diesel? If a 6 cylinder does it have one or 2 cylinder heads?

John,

We need to come up with a little FAQ forum about identifying Cletrac tractors, since such a large number of posts are just asking about IDing someone's tractor.

Maybe a sticky post for HG - General - OC-3 forum and one for the rest of the models forum?

Excellent idea, Maybe some members could donate a few identifying pictures to help with the differences.

It's a 4 cylinder,magneto ignition,has a water pump, gas tank under the seat(noticed that the oc-3 is up by the battery in some pics I have found)and has an Anderson blade on it. The rear end hooks to the back of the frame with u-bolts not between the rails. Working on setting up a place for photos so I can link to it. Where did they hide the data plate for the OC-46?

Look on the left side of the engine block near the head about in the center length wise. There will be a flat spot milled there and the engine model and engine serial number should be stamper there unless it is a replacement block. There were 3 versions of the OC-4 tractors. The first version and for right now I think that is what you have will have a four cylinder IXB Hercules engines. The next two versions are both 3 cylinder models. The second version is the B series and was made in Charles City. The serial number will be on a tag on the seat and the first number will be an 8. It that does not match up let us know and please also post the engine serial number if it does match up, Serial number plate should be on the dash if I remember correctly. Look for 3 small rivet holes about 2-1/2 inches apart. Hope this helps.

Well let's see if I can get this right the first time. I have one of the photos on photobucket. http://s689.photobucket.com/albums/vv25 ... pic039.jpg"

Eric:
Judging by your photo I would guess it to be the early, but not earliest model OC-4. It seems to have the four cylinder Hercules, guessing by the position of the intake and air cleaner. It has four rollers and 32 grousers.

The Earliest Oc-4s had an agricultural sheet metal. Do you have the grill? This is the most telling. I think the four cylinder was replaced either with a three cylinder diesel, available in 1957, and a three cylinder gas, available in 1958.

Hope this helps.

No grille but do have the top part to it and it is shaped like my 77RC. I had a little time between sleep and work(night shift stinks), found numbers on the flat spot on the block. They are 6351316TC and below it are IBX-3, which make it a Hercules. I hope that the ID plate is not below the gauges because there was some torch cutting in that area, guess to give better access to the clutch and bellhousing. Does anybody know the point gap setting? Spent 1 1/2 hours at Napa looking through books to find points. has no spark so that's where i start. Manual will be here soon and then the real fun can begin. Looks like major motor work is in the future by the way the plugs look, badly oil fouled.

Thanks for all the help so far,I'll try not to be to big of a pest.

I sold parts for 17 years, but I've been "out" since the mid '80's. Usually, ANY ignition parts can be found if you have the distributor no. Usually they are made by Delco/ Autolite/ Prestolite etc and have either a tag or stamped no. which should get you all internal dist. parts

We like pests that bring us new Cletracs to investigate ! You won't bother anyone here. Have fun..........

Eric N · February 22, 2009, 08:08:17 AM

Thanks roadrunner, I did get points at NAPA but they arn't put in yet, work schedule and weather has sloowed me down some. Next question, does the serial number on the block give an aproximate time frame of the build since I can not locate the data plate for the crawler? When taxes are back some of it is going to go to rebuilding of engine and hope some left for the tracks.

Yes it does. I did have that information, but lost it to a basement flood. Also behind the magneto is a casting date for the block. The engine would have been several months later as bad in those days the casting were left to age before they were machined.

John Schwiebert · February 22, 2009, 11:50:46 AM

I forgot to add the four cylinder OC-4 model was not made for a long perioed of time. It had a relative short production run of less than 3 years.

Eric N · March 16, 2009, 02:01:20 AM

Finally had a little time and some good weather(heat wave of 45). Got the points put in and there is now spark and I believe that it is time correctly. Didn't sound right when cranking so checked compression and 1 and 4 were very low. Removed tappet cover and cranked it and found that exhaust on 1 and 4 not closing. PB Blaster down the exhaust manifold and playing with the valve they are now moving. I am letting them sit over night and then going to try to crank it over with the plug out and watch the valves. Only 2 more days of warm before a cool off so hope everything loosens up and it will start.
