Should've asked here first--Oliver Crawler

[440roadrunner]

I just made a deal that I'm sure I'll be very sorry for. I guess I have "big ideas" bought a junk Oliver crawler that someone made a horrid job of uh, "installing" a Pintowed 4 clanger and auto trans---forget that--it's gone.

What occured to me is that I should starte looking into the REST of the story. This is essentially a stripped chassis, without the aforementioned "engine" and doesn't even have the original grill, hood, etc. It does have what the owner is calling a "Holt" blade

What do I look for in finding out what model this thing even is? It will be some time (weather) before I can get back over there and get the thing. Owner thought it was indeed a Cleatrac.

I guess the real question is, what / where do I look on the chassis/ what's left of running gear for ID/ marks/ numbers or even just details and measurements to ID the thing?

Just some pic's I found.
Check bottom of this page. http://www.bigoldiron.com/crawlers.html
And another. http://cletrac.org/pages/model/pic-HG.html
One more. http://www.ytmag.com/oliver/messages/114561.html

Oliver bought Cletrax and put their name on them and the numbers should be on firewall in engine compartment.

Thanks that sure a start. It might be some time before I retrieve this thing---my trailer is full of junk waiting for a "dump trip" and we stlll have snow in the Spokane area--there's a rather large pile of it between this thing and the way out.

I may be really sorry I got into this

check for the tags with serial number if they can't be found a few pictures with some track measurements may help

Here's some awful awful shots of the awful awful thing I haven't figured out--from the pix--what it even "was," yet. Please don't ask what I paid--I'm too embarrassed

hmm maybe a pic of the controls and dash from the drivers seat. it definitely has been altered, no need to be embarased I've drug home worse

[lt230s]

From the pic it's similar to my dad's OC-3/HG. The round gas tank, short track is similar. The blade is mounted different than his and he doe3sn't have roll cage.
Try to get some #s and maybe can help you a little more.

I know a guy who bought an old Oliver dozer OC-3 like that with a "blown motor" for 500 bucks,and he re-powered it with a 2 cylinder Wisconsin and used a hydraulic pump and motor to drive the original tranny ,and it worked out well..

I didn't get to see exactly how he did it,when I saw it, he had the conversion all done and was using it--and the motor and pump were covered up under a sheet metal enclosure he built for it--but it pushed dirt just fine,had plenty of power....

He ended up selling it for 1500 bucks about a year later to a guy who bought a house lot and wanted to clear it out himself..he regretted sellling it later on too!..

just think how much fun you'll have redoing it your way making it your toy if not you could sell it to one of the forum member good luck

[bear]

being a 4 cyl pinto engine and using the pickup in the background imo it looks like its bigger than a HG OC3 unless there has been more added to the front of the frame

Ya know that's a VERY interesting thought, because, I've recently gotten two belt-drive Craftsman GT's, one a newer GT 20hp twin, the other (wish I'd found it FIRST) a SS-16 with front mount snow blower. Needed about a 100 in parts Anyhow, I dreamed---for a little while---converting it to hydraulic drive

THAT IS something I'll have to think about

Very interesting journey you've had. Took me a minute to figure out what "ROP" meant

OC-3 or -6 is sorta what I'm thinking. The wx here is finally decideing to warm up, and I got the junk unloaded (dump run) from my trailer today, and spoke to the seller. He DOES have a large tractor with front loader, and committed on Frid/ Sat to try and plow around it (snow) so I JUST MIGHT fly the biggest piece home this weekend/ Mon/ etc

(My health and wx are big factors--arthritis for one)

Also I MAY have hit the "parts jackpot." There's a father / son in the neighborhood (urban hood!!) who have a rather, uh, interesting if not messy abode, much worse than I, and have bought additional (unconnected) lots and property in the hood. They have some REAL interesting stuff

Several Model A's all looking fairly restored/ runnable in the back of the dark shop

A LANZ BULLDOG!!!!!!!!!!

An old Schram compressor/ power generator manufactured with special heads/ intake from Ford flathead. The intake is divided--provides single barrel carb to running cylinders, and filtered intake air to compressor. Special heads contain blow off's valving, routing, etc. VERY interesting.

Anyhow, the son---for starters--has a carbed Toy p.u' 4x4 engine trans, that "should run" for a hundred. The thing is, the 4 / 5 speed has the adapter for the transfer connection--which SHOULD make that easier to shorted and deal with at the interconnection

Nothing solid yet--just thinking, dreaming, and .......

Further questions, check the links below. I DID get it stripped down, running of sorts.

ONE big issue is that the steering brakes seem weak, and it pulls constantly to (right? forgot) so one brake must be dragging? or the other weak? I assume this is a "simple" differential action, unlike back when Dad had the old Allis M.

HOW do I ID this thing, or does it even matter? IE is the chassis parts from OC-3/4/6/ HG pretty much the same? Are there pieces / parts of castings/ numbers that I can display to ID the thing?

MANUALS--been looking around efray--is there more than one "manual?" Found one someone called "service" but another called one something like a "technical information" so that is--is there just one manual or do I need a library to work on the chassis?





Onward we go, I guess just keep this thread. I'm still not sure what this thing is, model wise, here's a couple of other posts I made.

So now I'm thinking "what to put back in." I don't think I want an original engine, probably way too expensive, and I think I want to go with auxiliary trans, so I'm looking on ideas to keep the LENGTH short.

I need ideas on what transmissions can be modified/ used in order to shed the tailhousing. So what I'm thinking is:

Modern 4, V6, up to TBI that have or can be adapted back to carburetor

Maybe Ford Ranger/Pinto 4, Toy/ Dat/ Nissan p.u. ChevyII 4, but something inexpensive to build and maintain. (No hercules, Continentals or Volvos, ya know?)

Stick only--I don't think I want an auto

Of course the engine needs a clutch and box, so now.........

As example, found Toy 20-22?R with 4/5 speed out of 4x4, has short adapter to transfer case that MIGHT be a candidate A friend of mine just INSISTS that I find a Model A box--but adapting to modern engines, esp the *** stuff might be strange.


SPECIFICALLY I'm hoping to find some of you familiar with specific transmissions that CAN be shortened easily because of construction, or the fact that they are out of a 4X, etc. One BAD example -I remember- is the old 50s-60's Chev 3 speed which has the main ball bearing retained IN the tailshaft. That box, as example would be difficult to shorten.

I'd like to transfer that thinking----if possible---to modern boxes. There MUST be one, somewhere. I haven't gone out to look over my Ford Ranger box yet, which needs an overhaul, anyway.

As you can see, the frame has been butchered. "We" are gonna find out how bad my scarfing skills really are

I'd guess the old GM 4 speed truck 2wd trannys like the SM-465 and SM420's are the shortest ones,some Ford and Doge ones are similar used in older trucks up until the late 80's..-the SM-420's are the shortest of the two GM ones,and has a lower first gear ratio than the sm-465.but both are non syncho in first and considered "granny low"!..

I've seen them behind a 250 Chevy six in a few "hough" front end loders that formerly had Hercules gas motors,guys bought cheap with blown motors and repowered them with older GM pickup engines and tranny's--they simply used the 4 speed tranny to couple them to the original torque comverter via a u-joint and stub shaft,and left the tranny in 4th gear (1:1).

A lot of antique cars and trucks had small "short" trannys,like a Studebaker,they aren't much bigger than a generator!---but you'd probably want to avoind going with anything rare or costs a lot too I suppose..

I've googled "engine adapters in the past and found some interesting places that sell adapters that let you bolt most ANY tranny to ANY engine--one place I think was "Castlemania" out of CA,they had an impressive long list of adapters they could custom make for you with CNC or water-jet machines for a not so outrageuos price..My brother had bought a Toyota Skid Steer as a basket case and he was pondering usuing a GM 2.5 4 cyl Monza engine,and that place actually had an adapter listed that would have worked!--but he ended up finding a correct Toyota diesel from a forklift ,so he went with that instead--much easier to put what belonged in it back in..you might want to check google and you may be surprised to find how many adapters can be had..

(good luck finding a carbed engine though,here every one has dissapeared from the face of the earth it seems,at least 4 cylinder ones--straight sixes and small block V8's you might still find,but very few 4 bangers --junkyards here crushed EVERYTHING 1990 and older it appears,when scrap prices went sky high last summer)..

heres what I came up that may help id it OC3 track length 50" height 50" without exhuast pipe OC6 track length 121.5" height at dash 58.75"
if you have a serial # OC3 have a W in the s/n OC6 have a R with the exception of 1953 and 54 it looks like they shared the same #'s as for the steering it is brakes on a differential unlike other crawlers that use a clutch I haven't had a smaller cletrac apart but on the OC18 rear ends there are brake bands to each side of the differential

I don't know how much you want to get into, but another re power option is diesel engine from a reefer unit.

Depending on age, your looking at anywhere from about 28 to 90 hp. Cous has a Perkins sitting in the shed that came off of one thats 32 HP.

Personally If I had to go through that much work it would have a diesel

[440roadrunner]

UPDATE. Well good or bad, a Toyota 20R is what's going in there. I scored a used late 70's 20R, 4 speed, and ANOTHER engine / bell / clutch. Only about 175 in both. Here's the work on the back of the 4 speed which "should" allow an easy connection to the tractor drive shaft

(scroll down, sorry for posting on another forum, but it keeps everything in one place)

Also, have just scored a belt drive governor off 'the bay

Looks to me that with your skills (much better than mine I might add!) you will get this thing working soon. I kinda like the way you are going as there is not a lot of "original" to work with and it's interesting to me that this will be a Toyota powered Oliver.
