Will Dodge Posted March 24, 2021 Share Posted March 24, 2021 So I am starting a NEW post to see if anyone can answer the questions below? If you have rebuilt tracks or have personal experience, please chime in! I have all of the sources to do a build but before I pull the trigger I want to verify info. There will be a cost savings to do all inner and outer belts the same width if that is important. Continuous bands pre cut and drilled. So in theory just bolt on the grousers and other parts and install and play. (Sounds too simple) Measurements, photos and drawings are helpful! How many grousers on the left and right of M29 Are they all the same number? How many grousers on the left and right of T15 What is the proper thickness of the belting? What have others used with success? Too thick and power and steering problems and damage. Too thin and ???? Width of belt? Full coverage? 7 inch? 2 inch? (I am unfortunately am a 2 inch guy) Grade 8 bolts? T Nuts? Rivets? Hot glue gun? What size has been successful? Rubber track pad options? Belting? Cast? Old tennis shoes? Anyone have one NOS pad? Supplier options? Who have you used? Continuous bands? Conveyer? Hardware? Tooling? Photos of the process if you already did some, or in process, or? If we start with information, I'm sure Patrick could put some great drawings and directions together in his free time? It's not like he is really doing anything anyways. 🙂 1 Quote Link to comment Share on other sites More sharing options...

Will Dodge Posted March 25, 2021 Author Share Posted March 25, 2021 55 or 56 ?? Does anyone know what the reason was for grouser count? Is there a sproket difference? Is there something in a manual that I missed? Quote Link to comment Share on other sites More sharing options...
Will Dodge Posted March 25, 2021 Author Share Posted March 25, 2021 Anyone that has rebuilt their track with belting, can you tell us the thickness and width you used and how it handled in use? Quote Link to comment Share on other sites More sharing options...

Is there something in a manual that I missed? There are both 55 and 56 grouser tracks (in both 15" and 20"). The sprockets are different for them too because the "pitch" (ie spacing between grousers) is different. The "dog bone" (or bogie wheel carrier (called a bracket in the manual) is also different....presumably has to do with spacing as well. There is nothing in the manual, but the ORD 9 does have 4 different sets of tracks listed (1953 ORD 9 G179). I think someone mentioned having some information on the engineering reports regarding these track changes, but I have never seen them. The earlier ORD 9 G154/179 (1944) has one set of tracks listed for the T15/M28 and two sets (15" and 20") for the M29 and M29C. Again, I do know that there are both 55 and 56 grouser 15" tracks, so presumably the same is true of the WW2 era 20" tracks. Hopefully some other folks can chime in.

Will Dodge Posted March 25, 2021 Author Share Posted March 25, 2021 Were the track changes from refits? Or production changes? Quote Link to comment Share on other sites More sharing options...
Will Dodge Posted March 30, 2021 Author Share Posted March 30, 2021 anyone have input on the belting they have used? Bolt types? Quote Link to comment Share on other sites More sharing options...
Patrick Tipton Posted April 1, 2021 Share Posted April 1, 2021 Will - the changes in the number of grousers happened during WW2 so I am assuming production changes. The change from the outside stabilizing cable to the larger band on the 20" tracks happened post war. I am wrapping up the repairs on the hull of my T24 and should be done very soon. I have many track issues so will join you in figuring all of this out in a few weeks and we can try and centralize the data in one spot. 1 Quote Link to comment Share on other sites More sharing options...

M29C3284 Posted April 2, 2021 Share Posted April 2, 2021 (edited) Just wanted to through in some information on which track type was used where according to the three Weasel parts catalogs that I have. Service Parts Catalog for Carrier, Cargo, Light T 24, 1. Aug. 1943 905660 – Track, Drive, Assembly ORD 7-8-9 SNL G-154, G-179, Carrier, Cargo, M28 (T15), M29 (T24) and M29C, 15. June 1944 905660 – Track, Drive, Assembly, 15”, low guides, 56 grousers – used to ord. serial. 2102 908172 - Track, Drive, Assembly, 20”, high guides, 56 grousers, auxiliary cables – used from ord. serial. 2103 ORD 9 SNL G-179, Carrier, Cargo, M29 and M29C, 9. Feb. 1953 905660 – Track, Drive, Assembly, 15”, low guides, 56 grousers – used to ord. serial. 2102 908172 - Track, Drive, Assembly, 20”, high guides, 56 grousers, auxiliary cables – used from ord. serial. 2103 to 14108 except 13584, 13585 and 13660 (superseded by 908657) 908646 - Track, Drive, Assembly, 20”, high guides, 56 grousers, auxiliary cables – used from ord. serial. 14108 to 14158 except 13584, 13585 and 13660 (superseded by 908657) 908657 - Track, Drive, Assembly, 20”, high guides, 55 grousers, auxiliary bands – used from ord. serial. 14159 As you can see the official documentation lists four different tracks, one 15" and three 20" designs. Whether the last design, 908657, was ever install in production or just during post war rebuilds, I don't know.

Will Dodge Posted April 14, 2021 Author Share Posted April 14, 2021 Anyone find out why the 55 or 56 grousers are used? Does the tensioner work for both? The drive sprockets seem to be the same. As far as belt thickness? Anyone with experience have comments? Would there be an interest in full rubber tracks? Quote Link to comment Share on other sites More sharing options...
