gxbxc Posted November 23, 2018 Share Posted November 23, 2018 If you are polishing chromed diamond plate break out the brown tripoli and start buffing with a machine and s stiff wheel ,finish with a finer compound red or white and a softer wheel. If it is not chromed paint it silver or use one of the chrome paints 1 Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409874 Share on other sites More sharing options...

willie Posted November 24, 2018 Author Share Posted November 24, 2018 where you say just paint silver I was wondering what type of prep work is needed there is a lot of surface rust non through the paint would you recommend stripping the original paint off or cleaning and painting over it Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409905 Share on other sites More sharing options...
willie Posted November 24, 2018 Author Share Posted November 24, 2018 Gear jam'n fool I am not sure what type of transmission it has it doesn't have cab tilt to look and the owners manual was lost when we moved stations in the early 2000's it is a manual 4 or 5 speed transmission the last time it was driven the shifter slipped and we were unable to get it into any gear besides neutral we had to drag it back to the station with our brush truck I don't really know how a manual transmission works to be honest nor does anyone at the department we are trying to fix it to register it as a antique/classic apparatus for parades and special events below is the information listed on the registration #CF685F10-1768 Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409907 Share on other sites More sharing options...
41chevy Posted November 24, 2018 Share Posted November 24, 2018 (edited) Where is your dept located? Take a look at the snifter rod ( linkage ) going from the cab to the trans. Could be loose, broken or worn. Contact the MACK museum about a manual. They are all volunteer so a donation for the info is always helpful.

willie Posted November 24, 2018 Author Share Posted November 24, 2018 Paul if the case is that the rod is broken do you know where we could get a new one or how to fix the current one Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409925 Share on other sites More sharing options...
gxbxc Posted November 24, 2018 Share Posted November 24, 2018 If the shift rods are broken and you have all the parts a decent welding shop or machine shop should be able to repair it or make a new one some times they bind up from lack of lubrication and forcing a shift will bend the rod so they cant shift. If you want to paint the diamond plate and it is rusty you can use a scotch bride type of pad on a 4" grinder or even a smaller roloc pad on a die grinder . they also have a spot sand blaster that is self contained and it also works well 1 Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409928 Share on other sites More sharing options...
willie Posted November 24, 2018 Author Share Posted November 24, 2018 I was also told by another person it may be a one of the shift forks like i said I have no clue how a manual transmission works this truck has not been used as a front line engine in about 10 years we drove it periodically to keep it running if it is a shift fork how would I find where it is at and how would I find the shifter rod Thank you all for your help so far and thanks in advance Quote Link to comment https://www.bigmacktrucks.com/topic/54875-1972-cf-mack/#findComment-409931 Share on other sites More sharing options...
