Popular Post binderbob Posted July 24, 2019 Popular Post Share Posted July 24, 2019 just acquired a 1961 G-75 LT with ENDT 673 engine, and triplex trans. what kind/weight of oil should I use? thanks for your advice!! thinking of rotating engine with starter with fuel shut off, for a few times and hope to see oil pressure, over a week or so. then changing oil and fuel filters and hopefully starting the girl. any other suggestions? existing fuel in tanks looks clear and clean. 14 Quote Link to comment Share on other sites More sharing options...
j hancock Posted July 24, 2019 Share Posted July 24, 2019 Fabulous looking G! How does the oil look on the dipstick? Any history about the engine? 15-40 diesel engine oil such as Rotella or Mobil Delvac. 1 Quote JimIt doesn't cost anything to pay attention.

HeavyGunner Posted July 24, 2019 Share Posted July 24, 2019 Sweet truck. Be sure to document your progress. Hint hint we love pics and a good story about an old Mack. 1 Quote The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living.The government can only "give" someone what they first take from another.

Lmackattack Posted July 24, 2019 Share Posted July 24, 2019 if it has the period correct luberfinder it likely has to fill up that whole filter assembly before you start to see any oil pressure. thats how it was on my END711. you might be able to pull the turbo oil feed hose and pressure the block with oil first if you want to play it safe? I think there are some aux ports on the side of the block as well where you could force oil into it? 1 Quote Link to comment Share on other sites More sharing options...

Had a guy come in to the dealership with just such a truck that was started after decades and was smoking black.

I cleaned 30 lbs of mouse nests and droppings out of the air cleaner housing. Great advice...check all intake pipes and inside the turbo. When I start a truck that's been sitting a long time, I like to pull the valve covers and pour the new oil over the rockers so it runs down over the lifters, crank, etc. Pressurizing the oil passages would be even better. 1 Quote Link to comment Share on other sites More sharing options...

JoeH Posted July 24, 2019 Share Posted July 24, 2019 There's enough mud on that steering tire for 30 years sitting, but that cab looks rust free. Dirt floor barn find? There is no visible rust, must have come from a no humidity state... 1 Quote Link to comment Share on other sites More sharing options...
JoeH Posted July 24, 2019 Share Posted July 24, 2019 (edited) Heads up algae grows in diesel, or at least in the new diesel, so you may want to make liberal use of the fuel tank drain and flush the tank out real well. They make a fungicide additive that kills the algae but it doesn't dissolve it. It'll clog things up pretty good. Flush tank, change fuel filters, put some fresh fuel in it and pump new fuel through the system via the (hopefully equipped, but if not it's easy to install) fuel hand primer pump. You'll want to prefill the new fuel filters, and make sure you lubricate the fuel filter orings. And make sure old oring comes off. Never know with a 30 year old sitter....

Looks as if new tires were installed before storage, and not one sign of cracks or weather check. Yes dirt floor barn find. sitting for 25-30 years. no rust/corrosion , frame clean, has always been a northern mn truck. Owner was a flatbedder and made many runs to Alaska. complete with 8 track tapes. picture is of her coming out of storage. 3 1 Quote Link to comment Share on other sites More sharing options...

Prowrench Posted July 29, 2019 Share Posted July 29, 2019 I would change the oil prior to cranking, if at all possible remove the injectors first and spray Kroil,or Thrust, or PB Blaster in each cylinder prior to cranking do this for a few days to free up the rings . Then crank the engine with the injectors out (no compression) when you have achieved good oil pressure then reinstall the injectors and light it up 1 Quote Link to comment Share on other sites More sharing options...
