enlarged the picture and saw the mounting bolts removed after post. possibly the manifold was in process of removal ??? this is another "but doc I don't feel good ; what's wrong"??. questions asked yet "Doctors== BMT crew" don't have ALL the particulars to the ailment.. was the manifold being removed to repair crack ???? was the shutterstat line disconnected before the issue ???

did you check the picture showing the thermo housing ; the shutterstat is disconnected???? seems there is more to this coolant system then I think we are aware of. by the corrosion in housing (which had a crack) shutters disconnected = meaning full time open ???? if top of thermo housing is there . for me it would be clean up assemble, fill with diluted water =some conditioner not straight water . run system see what you have. leaks ??? signs of coolant in oil??? not sure of weather conditions in turkey where truck is located ++hot-cold=humid ??

welding alum is a talent in itself ; dirty alum can be a total challenge. stick rod alum a real Pain. wire feed is fun when mastered.

It's the golden years !!! doesn't get better only worse.. the time together !! OH how lovely. mines not talking to me now!! and that's a positive.

another pass it on: Feb 21 2026. Copake Auctioneers:: lot 335 large group of Mack related items. rest of auction very interesting for that "man cave "items. 266 route 7A / Copake ,NY 12516. found on auction zip. hopefully this is of interest to some . apologies if some one on BMT had some quite bidding going on and this made others aware of lots .LOL

martin mentioned is still "in the fleet". pulled by ole #1 Mack . some times for parades etc. one of the notable projects I dreaded was brake job on the martin, 12in ? brakes which had to be cleaned and rebolt new blocks on. proper setting of the GREASED wheel bearings ; wheel assemblies had to flop around with inner nut so outer nut installed bearing properly set. P I T A

tire size to me is one of the small issues. someone has to be right on with a welder and measurements. complete change over done correctly will take some .???? 2in bigger dia tires is only one inch on each side. hit a crossmember then cut -reposition and weld back in. mounting to a walking beam suspension ??? picture looks as if the blue spring assy have been torched for removal. ??? hopefully this topic will have plenty of updates ; let the BMT folks know what end results are.

definitely only one axle brakes. the valve mounted on inside of cross member shows only two rubber air lines coming off. the feedline must be brass looks to have a major kink in it ; bet those brakes were slow reacting. I'd say the one brake with "offset" push rod is missing a snap ring! if that was the only failure on this system.!!! the "new" system is greatly up dated ;but I 'll bet on a clearance issue with the 30/30 cans. 24/24 might work if they are even available any more. had customeryears back had a martin lowbed similar to this. a real P I T A

question is :: what's wrong with the water manifold ???? pin holes / cracked??? top half missing ??? little corrosion can be cleaned up . being aluminum; extreme care in the clean up. emory on piece of flat stock to clean off top mating surface and keep it flat. small file by hand clean inner surface thermo sits in. wire wheel on drill faster : but can also disform the alum surfaces.

the wear ring seal has a : thinner felt lip with standard metal housing OR the metal housing thinner with same felt can't recall. point is the seal allows for the wearing taking space. which is why the crank turned hard as it did with wrong seal combo. positive note :heck of a situation if it was thought to be OK just needs to wear in after clutch /transmission installed.

now that deserves a full page of likes!!

I don't think it as "so much money blown" ::: more like money has been spent for an investment AND the knowledge gained by hands on is considered PRICELESS!!!

looks real good. see it's part of a fleet with the 600 in the back ground. some where in one of the many boxes in basement is the DM800 from many yrs ago I built having the pete wrecker body installed also having the red/white/blue theme.

drove by PLunske's yesterday . too much traffic to slow down. that Diamond T has different cab then Waterbury Mack's T wrecker. don't think I would have stood that T on it's rear axle if Waterbury had a tandem not single axle T wrecker when I attempted to hook a DM600 roll off and move !LOL

Yes Sir I did notice that. I have realized that in many instances my mind is failing; to see your posted engine pictures and others posted here . still brings a positive smile and some great engine building memories to this ole man. THANKS every one. there is an auction I found today on auction zip having unbelievable Mack memorabilia ; I didn't want to post it if possibly some one here has a bid on it . now lets not go off topic.
