16  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Re: OK... I got a question on drain plug locations on: April 28, 2011, 08:57:05 PM
ah yes.. I know that the ONE plug I can see looks like a pipe plug. but dang if I can see another! My assumption, based on the angle of the finals when installed, is that the REAR plug MUST be the fill level indicator plug, and any plug closer ot the front of the diff would be the drain plug.

am I making the right assumption? Just I cant LOCATE said front/bottom most plug! Geez!

NOBODY knows this answer?
18  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / OK... I got a question on drain plug locations on: April 26, 2011, 09:29:54 AM
Looking at the Service manual for my 51 dated HG-42, the diagram and instructions shown for the location of the fill level and drain locations for both of the final drive locations are pretty vague.

When I rebuilt and cleaned my final drives and put in new seals and all, I never really did look much as I was completly draining and cleaning them out. Now that I want to check the levels, I am just wondering if I am actually opening up the FILLL LEVEL INDICATOR plug hole or the drain hole!

So, looking under the crawler, from the rear, I see a clearance hole thru the track frame, near the back of the drive, to access a slotted threaded plug in the final drive. I have to assume this is the FILL LEVEL INDICATOR  hole, and not the drain plug? its about 3-4 inches UP from the bottom of the drive casting. seems about right for the 1.5 pints of oil to come up to.

If my assumption is correct, and thats the LEVEL INDICATER HOLE, then where does one DRAIN the entire unit? Where is this drain Plugs location? Is it one of the lower casting assembly bolts perhaps?

I just cant see it anywhere.

like I said, I paid no mind when I had them apart as it was completly torn down and cleaned out and I just filled up with the recomended amount of oil, not really thinking much.. Now, as I have been running it, I would like to check the levels from time to time.

where are you located? I may have some parts you seek....I have a hood (original . nice and stright but with some pitting) front grill (looks like a repop) and side armor, or panels. My crawler came with some sort of Avery tractor gril and I like the looks of it, so its staying...


I even have a set of the heavier duty repop fenders.. I wont be needing them after building my own set of very stout flat top fenders.

Send me an email off line to :

and we can work out some price...
20  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / hi back seat on a HG? on: February 23, 2011, 08:21:38 PM
I seen a few pics of a hi-back style seat, with NO arm rests, on a HG.

Anyone got one on theirs? Was it optional equipment or a aftermarket add on later?

Does it attach to the standard seat frame springs of completly differnet mount?

I think the standard seat on mine isnt the most comfy I ever sat on so am exploring purchasing one of these hi-back frames if they were stock parts

anyone got one for sale?
21  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Re: PART NUMBER FOR "LARGE OIL SEAL" on: February 09, 2011, 01:29:47 PM
large oil seal Part number = Timken #415447  (5.750" x 6.624" x 0.625")

Small oil seal part number= Timken # 470764  ( 2.375" x 2.996" x 0.500")

I can tell you this:

Zimmermans was by FAR cheaper than my local NAPA prices.. Go with the guys that know their stuff!
22  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / what model is this? on: February 08, 2011, 08:24:06 PM
looks like a OC3 with the 3 rollers vs the 4 rollers (in fact, owner states its a OC3)

has a 3 cyl GASOLINE engine, so he states

Looking at rear, its awful narrow gauge. BUT, notice the tracks... they are wide, but with an "offset" design on each pad with the holes offset toward the center of the crawler.

Owner just called me out of the blue offering this to me. Non running. I would only interested for the blade and tracks, but tracks may be pretty worn. Aint exactly the blade I wanted, and I sure dont want another crawler carcass around after taking the parts I could use!
23  Cletrac Tractor Discussion / Military Cletracs / Re: History of Cletrac military vehicles on: February 08, 2011, 07:47:45 AM
David, enjoyed this article on the military cletracs.

I am particullarly interested in any other photos or information on the HG42 military version.

the picture you posted was one I hadnt seen. I did, however, see a different angle of the same tractor, from the left rear looking forward, showing the pintle hook, rear tailights, etc.

Unfortuantly, I no longer have the book that this photo was in.

Do you, by chance, have a copy of the book " Cletrac and Oliver Crawlers" by P.A. Letourneau?

if so, is it possible to scan this photo / caption and post on the forum?

I think its got a mistaken identity under its caption calling it a OC3..

Thanks! Any other info/photos you or others here  have on the HG/OC in military configuration would be higly appreciated!

I can be contacted off line if you wish:

wc57doggieboy@yahoo.com

thanks!

further info.. yes I restored it mechanically and shot it with a thin coat of yellow. I tore town both tracks and replaced seals, adjusted bearings, replaced all rollers with rebuilt, re-lined gas tank, added one wire alternator, rewired, etc.

still needs a much better set of tracks. these are at their end of life use, I think.

The grill is SUPPOSED to be off of a 30's Avery tractor. So my buddy told me. I have an original hood, grill and side "armor" for this. I just left what was on it for now. I too like the looks of it and it being a little "different"

As a military vehicle freak, this just cannot stay yellow! I want it O.D. green to match my military trucks! add a few invasion stars, hood registration number, a rear mounted pintle hook and eye bolts, head lights with brush gaurds, etc!!!!

I bought this crawler from a freind who owned it for the last 6-7 years. He lives in FT. Worth, TX

He bought it from a older gentleman in Loiusiana then. This guy apparently bought it from auction, many years earlier, from the forestry service, appaerntly seeing service dragging cypres outta the swamps.

(incidently.. my buddy who sold me this crawler has a back issue of some tractor magazine that has a 1951 dated photo of ALL the crawlers that the forestry service bought from Oliver, 12-14 in total, in a line up taken in the LA area when in service.

He firmly beleives that one of them tractors in that photo is this one. Neat... But I dont care either way.

anyway, this prior owner in LA had the engine rebuilt sometime in 84. Had a rebuild tag on the engine block stating so.. must have seen very little use after that, as the engine is in really great powerful shape, and when I tore down the clutch for the AUX install, the clutch looks brand news

well, here it is.. proof of the pudding as they say, that it runs indeed.

After my AUX install, I got around to rigging up a simple rear drag blade, operated with a manual master control lever off of a Farmall cub.

Works OK, I guess, but the angle of the operator to lever positioning is awkward.

Looks like a true, hydrylically operated front push blade is in order for the future!

Chris in NY? Still got one for me bud?

BTW... these videos were taken today, Friday, Feb 04, 2011, in my driveway, in Frisco, TX
Yes.. We here in Texas got a lot of ice and snow over the last week... Been crippled for travel here. Today, woke up to yet anotehr 6 inches of fresh white stuff.

Here are my video's playing with the HG.

27  Cletrac Tractor Discussion / Military Cletracs / custom data plate builders out there? on: February 03, 2011, 08:57:58 PM
anyone got a good source for a person who can make custom/reproduction data tag (plate) p?  Someone who can acid etch a duplicate from a picture of an original plate, or make a custom plate that has a "blending" of information into a plate?


Thanks
28  Cletrac Tractor Discussion / Auxiliary Transmissions / Re: UPDATE: AUX conversion ..DONE!!! on: January 24, 2011, 07:55:08 PM
no pix yet. thought I would wait until I repainted it all. right now its part yellow, part primer etc.

A list of "changes" or better put, "deviations" I made from the two on-line AUX transmission articles.

1) used a stock model "A" cross shaft instead of finding me a piece of 7/8" diameter cold rolled rod.. Not getting lucky on the
    "remannts" section of the local warehouse for a short peice to purchase.
    This worked out well.. Had the hole drilled in the center of the shaft to mount a model "A" shifting fork.
    Same on the lever end for the linkage.. worked out well.

2) Built a removable linkage arm, one that uses a lenght of flat bar and a small lenght of pipe drilled with a 7/8" id to slip
   over the end of the cross shaft. In that I drilled a hole to secure this using a Grade 8 1/4-20-2" bolt

3) Using the design noted in #2, I was thus able to mount the entire assembly of bolted transmission, adapter plates and clutch housing as one assembly onto the engine. this saved the step of fishing the TO return spring inside a small access hole. Also, doing this I was able to use the otherwise inaccessable final clutch housing mounting bolt hidden behind the lever arm when installed. Bolt first, slip on the lever arm and secure with 1/4-20 grade 8 bolt.

4) instead of welding two (2) bolts ont othe inner mounting plate to mount the gas tank bracket too, I drilled and tapped a set of 3/8" threaded holes. to this I bolted down the welded up bracket. No big deal, thought I would mention.. its an option.

SUGGESTIONS: My entire setup is bolted together, allowing dis-assembly at any time. In fact, it saved me a lot of headaches as i needed to take down and put back together a number of times thru the install..

ALWAYS use grade 8 hardware... I thought, as I didnt have a 1/4-20 x 2" at the time, I could just substitue any old grade 2 bolt I had lying around to hold the shift lever to the cross shaft. after about 3 or 4 cycles of clutch engaging, it nearly sheared the bolt in two! I then realized I had the same grade 2 inside holding the shift fork to the cross shaft! Replaced that with a grade 8 as well. hope it holds up.. otherwise, welding is in order, possibly why John Demarrias welded all his parts together. for now, and if it holds, Ill keep it all fully bolted for disasembly.

anyway, I am no expert, but I AM a bit wiser having gone thru the process once! I learned a lot, learned how i really have little patience anymore, and learned to accept my constant grease under the nails and cuts and scrapes on the hands!! now to get the wife to understand and accept my short comings.  Smiley

fixed the capillary tube. No more leaks, didnt have to buy another one..

Anyway, took it out for a short spin.

All looks well...

Boy, does this transmission really make it slower! Putting the transmission in 4th and the original transaxle in 1st (originAl speeds) vs the transmission in 1st and transaxle in first really is quite a difference! wow!

.. put the transmission in REVERSE and transaxle in REVERSE and you go forward.  or was that the tranny is reverse and tranasaxle in forward speed and you go backwards.... Funny anyway the combinations you can get.
30  Cletrac Tractor Discussion / Auxiliary Transmissions / UPDATE: AUX conversion ..DONE!!! on: January 21, 2011, 12:00:23 PM
well, an update of my progress to you all.

FINALLY COMPLETED THE INSTALL TODAY.

 I can say I had a number of issues to contend with, but I finally got around them all. Had some pretty frustrating times, but its now behind me and the crawler is back together.

(BTW.. for anyone who might have read this post originaly, and my issues with the clutch not disegaging... It was a simple matter of leverage, lever arm location and all that. FIXED!!

Anyway, its together as of this afternoon.. I started it back up, and drove it a bit.. VERY little mind you, as my capillary tube to the oil pressure gauge burst! I guess I must have kinked it too much while moving parts around all this time.

arrggh.... one more setback..

Anyway, just the last step in this.. I got the battery relocated, cluch leverage and linkage all nice and tidy, etc, etc.

Will see what I think of the new LOWER gearing soon!
