I’m at my wits end the Jack shaft won’t move across far enough to engage with the ring gear on the clutch basket I’ve replace worn bits in solenoid replaced Jack shaft with a one piece all ball racing one still the same problem. The only thing I can replace now is the starter motor any help would be great 

Was the solenoid plunger the same length as the original one you 

The plunger is the same size when you say stater clutch is that a part actually inside the starter motor 

Yes it’s in the nose cone of the starter so you will have to remove the whole starter motor 

Thanks I got it sorted end up getting a new starter and I will rebulid the old and keep it as a spare 

What was wrong Robbo? Was it blocked up in the throwout shaft space?

When I put the 2 starter side buy side and push the button mounted on the solenoid the new starter motor spline pushed out all the way where as the old one only moved about half so not sure why something to do with stater clutch inside the nose cone 

I could wrong but I think the starter clutch is on the armature side of the starter that may not affect the throw plunger side , was the push button 

This is very tempting in this situation 😂
