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

Hey, 440, Now that is some innovative engineering. Sometimes we just have to come up with a solution to a problem, It don't have to be pretty, just get the job done. Nomally when I'm working in the garage at home, I'm all by myself, so I have had to come up with some creative ideas to get the task done.

Well today  I'm not sure if I really made progress, or not.

I pulled off the suction hose and inspected it, looked OK,   removed the filter,  then went to the hardware store and bought a screen door spring.  My intention was to use the spring inside the suction hose for an "anticollapse"  device

Everything was "great"  until I tried to stretch it.   Had one end in the vise,  the other end in vise grips.   THE END CAME OFF THE SPRING   and whacked me in the back of my left hand.  Cut me up pretty good.  It will be sore for a day.

Anyhow,  it is now FASTER,  alright,  but not nearly  what I expected.   I'm wondering if the replacement valve---a cheapo-- is causing a restriction.     I should have timed it   before/ after.    While improved,  it probably still takes over two seconds to get the blade up enough to be really off the ground,  and SEVERAL  seconds to get up substantially,   over a foot, say.

You cannot break it if it's broken,  but....
You can fix it so it cannot be fixed!!

O. K. What is the inside diameter of your hydraulic cylinder? What is the length of stroke? Set the engine RPM so  you can retunrn to that exact RPM and I also need to know what the RPM is. Measure the time it takes to raise the blade or in other words the length of time to extend the cylinder. Get me those measurements. Also do you have a pressure gauge/ If so have you checked the pressure on the system. Also remember the rated GPM of a hydraulic pump and the actual GPM is not the same. Rule of thumb is actual GPM is 80-85% of rated pump flow. More questions?
