9/22/12 - I ask that you please add a signature line to your profiles on the Cletrac Forum to help me to determine who is spam and who is not. You don't need to drop everything and do this immediately, but please do it when you get a minute and you are visiting the forum. Just go to http://cletrac.org/forum2010/index.php?action=profile and put something in the signature area. If you no longer want to be a member on the Cletrac Forum, please remove your membership.

8/10/11 - Added a new board: Trucking and Hauling

5/30/11 - Just added several new pictures to the Photo Gallery, including several Alfta Track OC-4 working in snow logging, several from the Chicago Road Show, and some from a logging show (not all Oliver/Cletrac). All these pictures are from around 1963 and were scanned from old slides given to me by my late friend John W. Davis. Go to the Photo Gallery and click on "NEW" to see these pictures. Quality is marginal, but I think you will enjoy them.

2/13/11 - Just added a new board "New members introduce yourselves here".

Folks, I just added a new photo gallery where you can upload your own pictures with descriptions, etc. Right now this is in the beta testing stage to see how it works out. Give it a try, but please keep a backup copy of your pictures just in case we decide to use something else. I would prefer you use your real name on the photo gallery, but if you really don't want to, please use the same username as on the forum. Please put your images into the proper categories and take care when your write out your descriptions and image names so people can search for them. I am learning this as we go. At least at the beginning, I have it set up where the administrator has to approve members. I am afraid we may get porn spam in here if we leave it open. To get to the photo gallery, use this link: http://cletrac.org/photos/

Folks, when you join the forum, or when you get the chance to update your Profile, please be sure to put your location and interests. Filling out your signature would help as well. I've been getting some spammers joining and posting links to sites that are completely unrelated to Cletrac or Oliver, or anything to do with tractors. It would make it easier for me, as well as all the other members, if you guys would put your location and interest in your profile. See http://cletrac.org/forum2010/index.php?topic=1299.msg5184#msg5184

Thanks,

Hi folks,  from N Idaho area.  I always "get myself"  into this kind of thing with both feet mired in the mud

Bought a junk Cletrac,  looking for suggestions on engine (swap)  and help with model ID  About it's only saving grace was the low (still too high) price  and it has a pretty substantial appearing (Holt?)  blade

Now this thing is ugly. REAL  ugly.  I think the cab will get yarded off.   It has a horrid Pintoed 1600?  cc with an auto sitting there, all froze up,  and some horrid concoction with an auto trans  (spaced away from the bell flange!!)

What might be some good combo's for engine / trans?

I"m not really enthused about an auto trans, but have some of you?

Is there room in these little guys for say,  a Maverick/ Falcon engine plus 3
speed?

Can you put larger stuff like Chevy inline 6, Ford 300, etc?

Do you need an aux trans with the larger engines?

Ya I know.  Lots of answers and no info





Ford Ranger/ Pinto 2000-2300 plus stick?

Old Datsun/ Nissan/ etc/ 4 wanger and trans?

Modify / shorten the trans?

I haven't even got it home yet, so haven't really measured up stuff.   How about stuff like "up to"  EFI  V6's, etc?  Obviously front wheel drive junk is out, I guess?

(Once again, assuming  I'd need an aux trans for the newer,  "higher RPM"  engines


I wouldn't be surprised if you guys just kick my a$$ right off of here  before things even get rolling!!

YOU'RE OUTTA HERE !!     :lol:

Well, I guess my first thought would be what condition the undercarriage is in? If it needs a lot of attention you might be better off salvaging what parts are usable and find another one to restore.

I for one would try to find a correct engine, They're still around and would save a lot of messing with trying to make things fit and work together. That's assuming that the frame wasn't molested too bad with the transplant of whats in there now. The Automotive engines make torque in the wrong rpm range to be very useful.

Thanks for the thoughts,  but "correct engine"  just won't happen, unless something extraordinary happens.    I'm not looking to have some sort of resto,  just a budget, running small cat.   Hence modern (well semi modern) power.    

Sources for me in this area  (N Idaho, Spkane)  are limited for older  "industrial"  or low rpm engines,  so I'm sure some sort of automotive with aux. trans is in the works.  

Well, first I have to get this mess home.  snow.  ice. cold.  winds

Judging from the gas tank and what bits of the original are showing I would guess that to be a newer OC-3. The front wheels and main spring look like the OC-3. You can see the bottom rollers too. The second picture shows the frame has been lengthened to hold the engine/transmission. The rear seat has been added with the rool cage.

If the drive train and undercarriage are useable, just put a small engine in it. A local person used to buy OC-3's then drop datsun four cylinders in. He used manual transmissions and hooked them straight up to the original drivetrain. I thought they were quite horrid, but they worked alright. It was like having an OC with the Slo-Lo transmission. The good thing about the Cletrac/Oliver system was that the bell housing did not mate to the transmission. So swaps were easy.

Good luck

Thanks for the thoughts.   I haven't looked this over yet,  but that is the sort of thing I"m thinking.  One thing I HOPE to do is make things at least presentable.    Maybe shorten the transmission/ tailshaft up

For example,  my old  Landcruiser,  which I'll never "do"  again,  uses  Chrysler SB V8, Mopar passenger (A833)  4 speed and an "Advanced Adapters"  that mates it to JEEP  transfer case.    

For example,  I could use that box  with the adapter, which would give me a fairly short OAL on the transmission.    

I do have a small Atlas lathe,  and might be able to shorten a box on my own.  

I do NOT understand why I do this stuff

Go to http://www.youtube.com/watch?v=VyhYv4hGgo0 and see what this guy did with a Cletrac 20K. You might find this exciting and want to do the same thing with what you have.

That's quite a piece of gear!

One consideration with a different powerplant - the original transmission, differential and final drive gears were running on less than 25 hp.

You might run into problems putting more hp (and strain) on 60 year old components.....

Good luck with the reconstruction!

Well, barring accident, death, or sudden high taxes, tomorrow is the day!!!!   The seller even offered to drag it home for me a distance of about 50 miles one way.    Maybe he's feeling a little guilty

Anyhow,  I'm  now--for no good reason--getting excited about working on some greasy, old, piece.

I wonder if we should call it the "Pintasauras"

i like your enthusiasm! the sky is the limit.  maybe building a wheel stander would top the cleatasaurus. anyway, have you thought of a buick v-6 225? they have a heavy flywheel available for some low rpm use. maybe an sm420 trans. have a little fun. :)

Yes I have  but it's difficult to find them reasonablely  here.   Also,  I think I just about need something out of a pu/ 4x4  to reduce length.     Another alternative is to "luck"  into an automotive transmission that could be easlily shortened.

I spent ALL DAY   (I'm beat)    getting it to run some.   float was crushed in carb  (ice?)  and I fiunally found another carb in the shop.  Yarded out the fuel tank and jerry rigged a Tecumseh !! tank on the cab   for temp    The engine starts and runs but has one dead hole--don't know yet why

I DID  finally get it off the trailer at dark,  and ran up/ down the alley 60-80 ft or so.

BOY  what a two days!!!!!    Arrived onsite at about 10AM Fri  thinking  "we'd bump it loose"  and drag up on the trailer.    Frozen down.   Had to remove trailer fenders.  Had to block up tracks to get C frame OVER tires.   WHAT a day.  got home 4:30PM  completely beat

The only "sheet metal."   Don't know if the grill is origiinal, looks similar to later OC-3/ OC4?



The awfulness of it all.  Yes the frame has been lengthened, shortened, chopped up and butchared.



I have no idea if the Holt blade is morphed or fairly stock.  It shows some signs of repair/ welding/ etc



The holt blade



Pretty bad.   The seller evidently had little or nothing to do with this mess

Got busy today,  dumped off the blade and C frames,  removed the hydraulics,  and cab

I only had to remove the pump mount bolts,  2 bolts for the valve / resoivor,  and of course the cylinder clevis bolts    I only had to remove the return hose at one end from the tank to untangle from the Pintoed  mess,   and peeled the whole thing off a little at a time as one big connected unit.  Didn't   lose a drop of fluid


Tomorrow,  even  though today was great,  supposed to rain/ snow.     I'd like to get this mess yarded out of here, otherwise,  and just start over.


I'm amazed I"ve made so much "progress"  (regress?)  already

As far as sheet metal goes. That looks to be the original hood off of an OC-3, or maybe HG. The round hole is where the aaircleaner should come through. The back of the hood has a flange and bolt holes to bolet down and hold the gas tank in place.

The grill looks home made.

What a hack job, I am amazed that it worked at one time!!  Being a purist I would also try to find an original equipment motor.What does the frame look like where it is attached to the final drive? Is it the old style( butts up to the final drive) or the new style ( sandwiched in between the final drive casting and the differential).
Does the frame have any cracks in it?
