Guys: Did the M Crawler use a 6" pitch track chain? Also, I checked around a bit and could not find any info on the Dimensions for the PINs and Bushings. Any help would be much appreciated. Thank - You... Orangeman

Parts book shows the bushings are 1-3/4" diameter. Pins are 5-7/8" long except the master is 6-1/8" long. I don't know what the pitch of the track means? ------------- Waukesha B, B, IB, G, styled WF, D15, 615 backhoe, 2-Oliver OC3's, 4 Ford Model T's, 3 Model A Fords, AV8 Coupe, AV8 Roadster, 1933 Ford Wrecker |

Hi MNLonnie: Pitch is the original new measurement from Centerline of Pin to Centerline of Pin. So the outside diameter of the bushing is 1-3/4"- is there a dimension for the inside diameter of the bushing or the OD of the PIN? Thanks for the good insights Lonnie.... Orangeman...

The spec sheet is from this book. http://s590.photobucket.com/user/leeok/media/Mobile%20Uploads/image_9.jpg.html" rel="nofollow">  It list and gives specs for their tractors, crawlers, plows and implements available in 1935. Specs would be for 35 and prior models. It also has the Rumely 6 and AC Rumely thrashers and combines. |
