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

Thanks for the compliments guys,building this thing has been a real challenge. I had a few hours today to work on it and had just enough time to put the exhaust elbows on for cylinders 1 and 4. At this point it looks pretty much done, but there's a lot of clean up and detail work still, but it's getting there.

It took a while to wrap this thing up, I had to file out all 4 attachment holes due to pulling and distortion from all the welding. The new manifold bolted up easily to the old one but took a little effort to get it to bolt up to the engine block. I used a big stationary belt sander to flatten out the mounting flange, it had a little curvature to it after all the welding.
The last thing I did was to blast it and paint it with high temp flat black. I'm sure it will burn off but a least it will look good while I assemble the motor.

Thanks Bill,
It was a challenging part to build and took some effort to compensate for the pulling, distortion and shrinkage caused by so many hot welds on such a small part, not an easy project. I hope the rest of the tractor isn't as much of a PITA.

Well i Finally got my motor mostly back together. After getting it un stuck it really just needed a valve job, new exhaust valves,  and a set of stock rings. The bearings were all in great shape too, we even had to re use all the brass shims.

I've found a little time to work on my tractor, the motor cant go back in until I address to worn out suspension and heavily rusted belly/chassis pan. It took some doing to get the chassis pan out, now i have to deal with the can full of worms I've opened up.

Got the springs, hangars and chassis pan back on the machine, that was a bit of a job.
