krusty Posted July 19, 2015 Share Posted July 19, 2015 Hi gang,I have longed for a B61 or similar for weekend tinkering fun and am still looking. Came across a local ad for a circular sawmill so I went to see it. The old fella passed away and his daughters were handling getting rid of his collection of mantoys. Spent a good couple hours there talking and learning about what a character he was and his old mill was his pride and joy. It was in very good shape so I bought it. Still need to get it home.It is powered by an ETAZ673A engine. Looks like he cut the frame rails right behind the transmission and welded steel legs onto the frame. Story was he ran that mill like that for many years. All is covered from the elements and plan to start bringing it home soon.I have worked on my tractor diesel, my dodge Cummins engine but never a Mack engine. I am sure I can get it started. He had a section of dash panel attached to the side of the engine frame with all the guages etc but any tidbits on firing it up? He took good care of his machinery so I dont forsee any issues. Also is there any service manuals available to ensure valves etc are set to spec once I get it going again or other things I need to be concerned about?Krusty,ps I will post a pic when I get a chance.

b61mack Posted July 19, 2015 Share Posted July 19, 2015 An ETAZ673A is a 300+ witch is a 315 hp. should have plenty of power. if it has been sitting a long time make sure the rack is not stuck, sometimes it can run wide open, make sure you can disconnect the fuel line quick if it happens.

j hancock Posted July 19, 2015 Share Posted July 19, 2015 Manuals show up on fleabay every so often.Give it a good once over and see if it will crank. Check for oil pres and strange noises. Probably was maintained if it was his pride and joy. Quote JimIt doesn't cost anything to pay attention.

hatcity Posted July 19, 2015 Share Posted July 19, 2015 have a piece of plywood, bigger than the air intake at hand. If it goes wide open, you can drop the wood on the intake and suffocate the motor Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/40990-my-first-mack/#findComment-297191 Share on other sites More sharing options...
krusty Posted July 21, 2015 Author Share Posted July 21, 2015 Any chance someone could briefly explain how to check the rack? I got the engine out of the building it was in today and tomorrow AM I will go with my trailer to bring it home.

krusty Posted July 23, 2015 Author Share Posted July 23, 2015 I brought it home yesterday. There are a couple pics in my gallery. Used my high lift jack and a few chains, cedar logs for it to roll on, to pull it onto my trailer bed. Man that thing is heavy. Back was sore by the time I got home thats forsure. My little B414 tractor would not pull it off of my trailer.Today, checked the fluids. Topped up the oil. There were a few mice in the air filter to intercooler. Cleaned that out. It cranked right over and I cranked for maybe 3 seconds. Then gave it a micro micro shot of ether and..... The turbine fan for the intercooler needs replacing but that is it! Lots of oil pressure. Rad is fine. Now I need a service manual and if anyone has one would you know the gear ratios and shift patter for these?

Loadstar Posted July 24, 2015 Share Posted July 24, 2015 Nice!!!..... Any pictures of the mill? I've always wanted one but never found one close enough. Quote Link to comment https://www.bigmacktrucks.com/topic/40990-my-first-mack/#findComment-297671 Share on other sites More sharing options...
b61mack Posted July 24, 2015 Share Posted July 24, 2015 you should be able to get the tip turbine freed up with some PB Blaster just spray around the inside of the fan to get it loose, it has sealed bearings.
