skydawg Posted April 26 Share Posted April 26 I`ve about given up on finding a nice B61 s/a tractor and am looking at a B67 w/ Unishift trans.So this setup has an air cylinder that needs frequent water draining,as well as an alcohol evaporator?Is that something that you fill w/ alcohol on a regular schedule? Thanks. Quote Link to comment Share on other sites More sharing options...
Freightrain Posted April 26 Share Posted April 26 Most B67 had the contour cab and are even tighter inside compared to the std cab. Just a heads up if you need leg, stomach, or head room. I'm not sure about all the maintenance of the unishift. Shouldn't be too bad especially for a hobby truck. I guess the first thing I would investigate is the air compressor. If it's worn and pumps a lot of oil that could be an issue with sludge building up. Before rebuilding my compressor, it would make milkshakes in the air tanks in short order. My air wiper cylinder was packed up and they didn't work well til I pulled it apart and cleaned everything. 1 Quote Larry 1959 B61 Liv'n Large......................

skydawg Posted April 26 Author Share Posted April 26 I`ve read a few tales of an aux case cracking/puking,and hope this is a result of poor maintenance,and therefore avoidable. Quote Link to comment Share on other sites More sharing options...
Brocky Posted April 26 Share Posted April 26 Vehicles left out in the rain with the shift tower exposed WILL draw moisture which settles to the bottom and then freeze in the winter thus cracking the bottom of the unit. Farm tractors, especially John Deere's were famous for this!!!! Quote Brocky Link to comment Share on other sites More sharing options...
skydawg Posted April 27 Author Share Posted April 27 I should add that I know alot of people that can make large amounts of alcohol evaporate...still no word on the Unishift device. Quote Link to comment Share on other sites More sharing options...
