seyser Posted September 10, 2015 Share Posted September 10, 2015 Does anyone know how many miles/hours a Thermodyne diesel would last before needing an overhaul? Did the factory have a TBO for these engines? 1 Quote Link to comment Share on other sites More sharing options...
Freightrain Posted September 10, 2015 Share Posted September 10, 2015 I think they fall under "Engergizer bunny". They just keep going and going and going and .......................... 2 Quote Larry 1959 B61 Liv'n Large......................

j hancock Posted September 10, 2015 Share Posted September 10, 2015 If you know it has a zillion miles on it and makes some "interesting" noises, it may be time to do an overhaul. Take an engine oil sample and see what a lab has to say about it. Is it showing fuel in the oil? Is it showing bearing material in the oil? Oil sample test by a good shop is money well spent. 2 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
1958 F.W.D. Posted September 10, 2015 Share Posted September 10, 2015 Is this a trick question?Like anything else. If properly taken care of and maintained according to accepted practices and standards, and assuming the equipment is not abused- it should last indefinitely.Like others have said....If it's up there in mileage and is clickety-clacking like a railroad track, then an overhaul may be in order.An oil sample analysis will provide a wealth of information for a small fee. I see you are in Mn......Contact almost any large truck or farm or earth moving machinery dealer, most of the big places either have a lab on site or send their samples to a central lab.You can also try Giles and Ransome Caterpillar in Bensalem, Pennsylvania- they are who I use. They have a lab in-house and will analyze any make/model engine oil, tranny fluids, fuels, coolants, hydraulic oils, etc. Call them on the phone with your credit card handy. They'll send you a sampling kit- a sample bottle, an overpack bottle, a draw tube (to drop down the dipstick hole), a self-addressed/pre-paid UPS envelope to ship it in, and the paperwork. You draw your sample according to the directions, seal the sample bottle up in the overpack bottle with the label affixed. Fill out the paperwork, seal it all up in the supplied envelope, and drop in a UPS box or call for UPS pickup. You should have results in 8-10 days if that long. Last time I did it 4-5 years ago it cost me less than $20.00 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment Share on other sites More sharing options...

Bigdogtrucker Posted September 10, 2015 Share Posted September 10, 2015 How does your engine run now, and what is it? Quote Link to comment Share on other sites More sharing options...
seyser Posted September 10, 2015 Author Share Posted September 10, 2015 My 673 turbo shows 300K+ miles, assuming these are original. The engine runs absolutly perfect, great oil pressure both cold and warm. Slight blue haze of smoke on cold startup but clears once up to operating temp. I belive this truck has had a pretty easy life. 1 Quote Link to comment Share on other sites More sharing options...

AZB755V8 Posted September 10, 2015 Share Posted September 10, 2015 Hell, At 300K that is just broke-in and ready to run. It a new engine if there is less than 250K on it. 1 Quote Link to comment Share on other sites More sharing options...
