Starter on Carroro 68.4

[Ivor2]

Hey
I've got a carraro 68.4 tractor and it's been sitting for a long time so i want to see if it will still run but the starter has no solenoid on the top and i don't want to spend a lot on a new one without knowing it's worth it . so i want to try the starter but don't know where to put the negative and positive lead . there's three places to put a wire on on it . Two on the top and one on the side . so i tried putting the negative on the side and positive on one of the top ones and it spun so i put it on the tractor and tried it but it didn't turn at all just got hot . so what are each pole for ? it looks like a perkins 4.236 engine .
Here a modern version of the starter ;Starter For Ford Tractor Diesel 2000 3000 4000 5000; SLU0002 701485503221 | eBay
Thanks

The starters I've seen get their ground from the frame of the tractor itself - no ground wire. Have you considered pushing or pulling it to start?

Welcome to TBN!

In the picture of the start solenoid, yellow blade lug is for the momentary start wire. The red + lug (not spade connectors) is where the + from the battery goes. Ground can go on the starter mount bolt or the frame of the tractor acts as the ground connection as @Roadworthy mentioned

Hey . Thanks for replies . i'll try again later with it . so just negative on the body of the tractor and the positive on the copper bit on the photo . What would be the valve adjustement for the tractor? or just common valve adjustement ?
Thanks

Hey
Thanks for your reply . so i've just been adjusting the valves and found out that one of the things that push up the valve rods is stuck in the up position and won't go down . Should i tap with a hammer till it goes down ? what would you guys advise ?
Thanks

Hey
I've taken the injectors out to check that diesel is getting into the engine but when i took the injectors apart to clean the needle is stuck in the nozzle . how would i get it out ?can i heat it up a little ? or something.
also to adjust the injkectors do i need an ajustement kit or can i use the mesurement of the screw that it was originaly ?
Thanks t

You could put the tip in some carburetor cleaner and let it soak. You need a injector pressure tester to set the opening of the injector properly. You could set the screw back to where you found it and hope forvthe best.

hey
Are the bolts that hold the tractor together are they thin threaded like the cylinder head or normal threaded ?

Do you mean are they fine thread or coarse? Not sure.
