Bad Starter? 4 Cylinder Perkins

Okay. I went to start the Massey Ferguson 470 tractor yesterday and there was nothing when I turned the key. Thought maybe the battery was flat. Today I installed a brand new 13 volt battery and turned the key, still nothing. Took the dash out and looked at the back of the key switch, all connections are fine. Double checked battery cable connections, all fine.
Jumped the solenoid with a screwdriver and she whirled but no cranking. I removed the starter and solenoid and figure on taking them into the shop. Think I"m on the right track or did I just remove my starter for nothing? lol Ideas?
 
I may not be of much help . but in my experience that symptom means a bad battery , or poor connections from battery. Try bench testing it direct from another good battery, that would prove one or the other...A good starter will have alot of twist(torque) and speed to it, and throw the drive out forcefully.....
 
Based on what you did the solenoid on the side of the starter is bad. Nothing when you use the key means the windings in the solenoid aren't pulling it in when you supply power to them. The way it works when it pulls in it both engages the bendix into the flywheel ring, and closes a set of contacts to energize the starter. The fact you were able to jump the posts means the starter itself is more than likely OK, but without the solenoid energized the bendix will not kick out to engage the flywheel ring.


In other words, Yes, you did the right thing pulling the starter. If it were mine I'd take it to my local repair shop and have them go through the whole starter, even though just the solenoid appears to be the problem, just to be on the safe side. More than once I've taken one in with 'just the solenoid bad' to find bad brushes, a dry bearing, etc, etc in the main body. Basically it's well worth the little extra cost to get it all checked to insure you won't be pulling it off again any time soon.
