880 starting

[oliverfanatic]

I recently purchased an 880 diesel that refuses to start if it gets below 65 degrees. The glow plug in the manifold works but doesn't help it start better. I have noticed that the starter is smaller than that of those on all the other 880 diesels that i have seen. I have it original with 2 6v batteries hooked together. Do the 6v batteries and a small starter cause it to turn over slow? When I jump it with my diesel pickup that has 2 huge 12v batteries it starts better. Right now the only way i can start it is with a shot of ether. Thanks for your help.

Try taking apart and cleaning ALL the battery connections and starter connections. Use baking soda and water or battery cleaner from the store. Shine up the connections real bright with a bristle brush and put them back together nice and snug. Coat the connections with a thin layer of petroleum jelly or grease. Battery protector from the store where you bought the cleaner is prettier. If all the parts of that tractor are stock, it should spin it over just fine IF you've got PLENTY of juice from the battery(s), and dirty connections can prevent a manly enough current. After all that work, if it still doesn't spin fast enough, take the starter into Auto Zone, O-Reilly's, etc., and have them test it. Best of luck!

Petroleum jelly, yes. Grease, no.

I like to use the spray on protectant, but what's wrong with grease? Isn't it about the same thing as jelly?

No, they are not the same. Grease is a lubricant carried in a calcium or lithium base. That base will not conduct electricity and is a solid. No problem, I suppose unless you open the connection at some time. Grease will then contaminate the connection and cause problems unless you completely clean it off and start again. Petroleum jelly will not cause any such problem if the joint is loosened and retightened as there is no carrier base to cause problems. So just plain common sense so as not to coat it with a problem for someone to deal with in the future.

Alright, point taken. What's dielectric grease made out of?

I think your problem is with your primary fuel pump. It isn't pushing the fuel up through the filters,the injector pump is having to pull it. What you describe is a classic symptom. You can get rebuild kits for those from www.external_link.com I believe. If not,try www.agpartsfirst.com. I think that will make a world of difference for you.

Dunno. If that is a question needing an answer I would suggest you post it on a 'leccy' forum or ask the manufacturer. Should be a haz-chem or data sheet for it somewhere.
