News: 10/5/12 - All new members are REQUIRED to fill out the signature section of your profile. Otherwise, you may be deleted from the forum. This is to help me determine if you are a member or if you are a spammer. Thank you.

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,
Administrator

I have a dual disc clutch in my Cummins/Dodge Ram and it can rattle pretty good while in neutral. Push the pedal in and it stops. Let it out and sometimes it's quiet. Under load and in gear it is fine. I think it's just a bunch of little sloppy places between the parts that add up and rattle.

It could have been war effort too. Look at all those old WW 1 tanks! And the steam crane.

When you have the clutch out check the flywheel bolts. A loose flywheel will rattle in neutral but not so much in gear.

I have a Vega clutch disk on order. The Vega disc has 6 springs which should help dampen the disk to clutch shaft spline play. The new disk I had on, the possible rattle maker, didn't have springs and there was more slop between it and the clutch shaft than with the old disc.

I did some googles on "clutch disc rattle" and found this to be a common problem and the springs help dampen the rattle. There can be a problem also where loose springs can cause a different kind of rattle but I'll take a chance on the Vega disk (made by Sachs).

I'll post on the results when I get the Vega disk installed. It is getting cold here in MN and the fingers don't work to well then.

Jack, If your referring to my user avatar picture, that is an OC46 which shares some attributes with an OC3. However that data plate for an OC4/46 is under the left side of the dash panel above the clutch pedal. I was referring to my other crawler which is an OC3.  Undecided

Has me puzzled to. Most every one I ever ran had some rattle, but it was always in the joints, but all that I had were with old joints.

Hello Mark -

Can't help on either of those numbers. The first is probably a Hercules casting number; the 112xxx is an Oliver part number.

Visible differences between the HG 42 and the OC3-42 are the front idlers and the knee action springs.

The tractors were available in -30, -42, and -68 (and possibly others) - the track spacing in inches.

Hotratz' picture is an OC3, probably a 42". Solid disk front idlers, with the track retaining guides outside the track chains.

The other difference not clear in his pix - the knee action springs are exposed and visible.

The HG had front idlers with a number of 3 or 4" holes in the disks, and the track was retained on the idler by a couple of ribs that ran inside the track chains (and usually got seriously bruised or beat up in operation!). The knee action springs were considerably smaller diameter, and enclosed in a round metal can so they weren't visible.

The model changeover from HG to OC3 probably occurred 1949 - 1950  - others here could be more specific on that date.

This may help narrow your age bracket a bit. The HG or OC3 designations would allow you to source most parts with no problem - they were either HG, OC3, or common: although there was some overlap (I understand) during the months of the change-over. For instance, I think the IXB-3 engine with the water pump may have been installed in some late HG's. I seem to recall an earlier thread that discussed that.

That is a cool picture! I'm guessing it was pretty worn out. Back then there weren't many people trying to save old iron from the scrap heap. The philosophy was to melt 'em down and make newer ones.

I did lots of listening and the rattle is definitely from the Clark unit. I replaced both bearings on the Main shaft before I got it running.
