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,

I have a BDH Cletrac and it's cold blooded, in my opinion. Takes ether to start it (probably needs rebuilding) and it smokes like a chiminey for a while, but after that, it doesn't smoke much and the engine developes reasonable power. Is that normal? Where can I get glowplugs? Will that really help it get going? Thanks.  Jim

My experience with my BD is limited but similar. Check the timing adjuster on the drive coupling though as mine slipped and it ran very smokey and was a real pain to start.  All the information I have is that they do smoke while the engine is cold, and sound un-smooth, but this should settle down when it warms up and work.  Instead of ether you could try draining the radiator and filling it with warm water, its a pain but works well, and also add some heat to the intake manifold, a burning rag, blow torch or I use an electric heat gun (DIY, paint stripping thing).  For glow plugs try Landis Zimmerman or Jerry Biro you'll find there details in the suppliers part of this site, don't hear them mentioned much though, my BD is a '51 and doesn't have the holes for heaters.

I live in England, got interested in Cletrac's when I brought an Oliver BD in 2001, I now have an Oliver BD a Cletrac BDH and another BDH for parts and have just brought a 1919 model H. I also have a british built Track Marshall 90.  Always keen to hear from fellow collectors.

Jim, it's normal.

Even when new, most of these diesels needed ether to start when cold. They even have a canister for using ether pellets, that would feed it into the intake. I don't know if the pellets are available anymore, but the cans work fine.

Just make sure your engine is turning over and smoking (so you know it's getting fuel) before you give it a short quick shot of ether. And don't stop turning the engine over until you know all the ether has been drawn into the engine and out.

The idle stumble is normal on some. I believe more with the Roosa Master pump. It smooths out under load and will not hurt anything. A muffler helps smooth them out.

My gramps Howard van Driest was Experimental Engineer at Cletrac and Oliver Corporation. After the plant closed, he and my uncle started an excavating business, initially using Cletrac and Oliver Crawler tractors.
