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 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:

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

Could somebody please tell me how to time the mag. to the water pump?  Thanks
2  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Re: IXB5 Timing on: March 10, 2019, 11:53:48 AM
Is it safe to assume that I dont have to time the gov. gears? My thinking is that unlike the ixb-3 the mag. is not gov. driven.

I have an IXB5 stationary engine that Im putting together that I recently picked up. The mag. Is finished and timed with the crank. The gov. was off ...the mark is an S on the gear that drives the gov.  I dont know what to look for on the gov. gear.  Any thoughts? Id like to get this running. Thanks Cork

  Just think how muddy it would be if it wasn't the dry season. Grin

OK, I give!  Spent a few hours trying to grind and press out one of four spindles...I don't want to work this hard!  Thanks to Chris I've made arrangements to replace my final drive housings with good ones from him.  I'm not the smartest Oliver owner out here or grammatical wizard...on my last post I made up the word "egged" Embarrassed  Frankly I would be a bit concerned if after I re-cut the threads  they may be substandard.  Counting on the cotter pin to subsidize the lack of good threads might be a temporary bandaid.  After working on mine I have no regrets about replacing my poor parts with quality parts.  Cork

Gazer,  Sorry I didn't get back sooner.  I would also check and see if the trunnion is tight on the spindle. Mine was so loose it wobbled on the larger part of the shaft and ruined the threaded end of the spindle, it also made the shaft somewhat egged shaped. The bull gear was so loose it chewed up the bottom edge of the inner bearing for the pinion and tried to grind its way through the final drive cover. Check also to make sure the outer bearing race for the bull gear is snug on the spindle's not a pressed fit but should not wobble.  I tried to post pictures from photo bucket and was not successful.  I'll get it figured out soon I hope.  Cork

Chris,  1st class find and job!

Sounds like I'm on the right path.  Thanks for all the help.  Cork

 Robert,  Thanks for the reply.  Glad to know that it might not be that tight of a fit and freezing the new spindle makes sense.  Cork

  I may be in over my head but I can't be the first.  I started out just doing some minor jobs to my early HG/ Cletrac it's down to a frame with a transmission/diff. case.   The spindles are bad and I have some very good final drive housings with spindles from a 42".  The question is - How hard is it to remove the spindles and replace the bad ones?  Has anyone done this and how do I proceed?  My guess is that I grind the weld on the inner trunnion and press toward the outside on the spindle...perhaps heat the outer part of the trunnion?  Any advice is greatly appreciated.  Thanks Cork

Thank you Chris.  On a related note I've never received the bulletin you asked me to share.  If I get it I will.  Cork
12  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Frame to Bellhousing bolts on: November 12, 2012, 12:10:29 PM
  I'm working on a HG68.  The IXK motor is bad and needs to come out.  My question is, Are there bolts behind the track hangers that bolt the frame to the bellhousing? I know on my 42's that blind bolts exist..2 on each side.  I'd be tickled if I didn't have to remove so much to get the motor out.  Thanks  Cork

John,  pm sent,   Cork
14  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Idler wheel on: September 20, 2012, 08:11:42 AM
Can I replace an earlier idle wheel with holes with a later solid wheel? Do I have to use the early idler supports or can I use the later OC3?  I'm working on an HG-68 and am not sure if some of these parts are interchangeable.  Thanks Cork
15  Cletrac Tractor Discussion / HG, OC-3, OC-4 & General / Re: Anderson blade removal on: May 29, 2012, 08:22:08 AM
Thanks for the reply Bill,   I've got an Anderson like you describe and removal was easy.   I thought that just maybe somebody had a "magic" solution.  It looks like a rosebud and BFH are the ticket.  The frame work for the Anderson is very well welded to the Oliver frame so dropping it is out of the question. The biggest problem other than rust is access to the pins from outside of the track carriage...Time to get creative.  Cork
