This question is actually about my oliver 880, but you guys are the most knowledgeable and helpful to a newbie, so I hope you dont mind the post here.

My 880 wont turn over. New, fully charged battery. When I turn the key I here a click in the little relay thingy on top of the starter. So I am thinking that my starter motor is bad, but before I dump $200 or so into a new one, I am wondering if that makes sense. I dont want to miss something easy and cheap to fix like a solenoid or something. Is there an easy way to be sure it the starter motor itself? As always, your advice is appreciated.

Rule out a bad soleniod first. The fact that it "clicks" doesn't necessarily mean it is making sufficient contact to crank the engine. WITH THE KEY OFF AND TRACTOR OUT OF GEAR connect one side of a fully charged battery (or a battery charger with a starting circut) to the post which goes directly into the starter and after checking again THAT THE TRACTOR IS OUT OF GEAR, firmly touch the other cable to the frame or engine block to complete the circut and bypass the solenoid. Either 6V or 12V directly to the starter doesn't hurt the starter, but I would use whatever voltage your tractor normally uses because if that happens to be 6V then appllying 12V can often overcome some problems and crank the engine whereas 6V didn't. If it cranks with the solenoid bypassed you've solved a part of your problem. If it doesn't, then you know at least part of the problem is the starter.

Is the relay is grounded to the top of the starter or is it somewhere else on the tractor? If it's on the top of the starter, then you could rule out grounding issues. If elsewhere, try removing the starter (you'll have to do that anyway to get it serviced) and run a ground wire (anything conductive) to the starter housing from the frame and try to get the starter to turn over while sitting on the ground. Or just sit it on the frame and try turning the key and see if it'll spin. If it won't spin, you may need a new starter. If it will spin with 0% load, but won't turn the engine, then just rebuild the starter as it may have worn brushes or whatever. Either way, i'd let a starter/generator shop check it out as they can usually rebuild them much cheaper than a new one costs.

Redtail..... ..donnna know 'nuttin' about Olivers.....but.....remember the 6 volt MANTRA: "keep'em clean, bright, and tight".

And this could also mean where yer starter bolts into the engine housing. Sometimes there gitts serious conduction problems between starter motor and block hole. Pull startermotor out a littlebitt and refresh with a "swipe" of sandpaper both the starter end and engine blockhole edges.

And definately consider replacing yer starter solenoid 'cuz the internal contacts wear and break-off and won't transfer battery power to starter motor..... ...Dell
