Blake,
First, thanks for updating the site. I want to resurrect the images on several past posts I've made that were linked to a now defunked image sharing site. Question: How do I get an image to take the place of the old links in my post. When I try to do this the image seems to default to the end of the post rather than the end of the paragraph in which the image link used to be. Do my images have to be linked rather than posted directly?

HG, OC-3, OC-4 & General / Re: Oc 4 not getting warm
Last post by eyeball-shifter - February 02, 2022, 07:20:04 PM
I think the OC-4s just run cool.  I can't get mine up to temperature on cold, winter days.  I had mine on fast idle for 45 minutes and could put my hand on the engine and it was just warm, the temperature outside was in the high teens.  I pulled the dipstick and touched the oil and it was just warm, parts of the radiator were a bit warmer, but not hot at all.  I didn't register anything on my temp guage.

Military Cletracs / Hood numbers
Last post by M2nut - July 11, 2020, 01:01:12 AM
Hello everyone.   I'm wondering if anyone can tell me the logic behind the hood numbers on m2 cletracs.   I'm puzzled why the data plate ordnance numbers are 3 to 4 digits  and the hood numbers are 6 digits ?  There are  a few period photos that some early cletracs that have 5 digits painted on the seat rail side .  Almost all period photos have the first digit being a 9, which probably was the serial number range assigned to the type?  Any ideas?

The rod spring 37202 is the return spring and should have pressure on the housing when the clutch is engaged.  The sleeve spring is an anti rattle spring the holds the release bearing on the yoke.  The important thing is to have the 3 112 211 screws all set to the correct length.

HG, OC-3, OC-4 & General / HG Clutch question
Last post by donlaflam - April 15, 2020, 03:38:17 PM
Good morning everyone-

I am a new to this group and a new HG owner with some basic mechanical knowledge, but learning as I go.  last fall the clutch stopped functioning on my HG, I tried many of the tips I found online about putting a load on, etc, however I decided to pull it into the barn and take it apart along with a few other projects that needed to be done on it. 

I pulled the case yesterday and found that the friction plate was totally shot.  I'll be replacing that along with the majority of the bearings inside.  My question, however is in regard to the springs within the assembly.  should I replace these?  they seem to function properly, however due to their age i'm sure they have lost some of their tension.

the two i am most concerned about are :

1.  Throw out sleeve spring  112754
2.  Yoke rod spring  37202

any advice you could offer would be most helpful.

thanks in advance,
Don

  Just wondering if this was a patented invention or not.
  "With a double-cut sprocket, the tooth pitch is half that of the chain. Therefore, the number of effective teeth is half the number of actual teeth. If the sprocket has an odd number of teeth, the number of effective teeth is fractional, and each tooth engages the chain only on every other revolution. This cuts tooth wear almost in half, nearly doubling sprocket life. The same is not inherently true for sprockets with even numbers of teeth."
  My model "E" CLETRAC had an odd number of teeth on the sprocket. I believe that the CAT model "60" also had an odd number of teeth on the sprocket.
  Seems like a very clever idea.
  Did all CLETRAC models do this? Did most manufacturer of tracked tractors do this?
Thanks in advance for any replies.
