How do i tell if it's the armature ?

A long bar tobturn the engine over is not real normal, but it does take some effort. You oiled the cylinders and bearings when you put it back together?

Following is armature testing:

DC Motor Armature Testing

For a DC Motor Armature, There is a simple method of determining the condition of the Armature.

Ok thanks for the guide i will try it . i did connect negative to the shaft and positive to the copper and there was no connection . Iforgot the dip rwo of the pistonsin oil before putting them in . Would that be it ? i did put oil in the cylinders and bearings

You can shoot a bit of oil into the cylinders, directly through the spark plugs or glow plug holes and see if that helps.

Hey
Ok so i took them all out again dipped them in oil and put them back in , and so i had put number 1 and 4 in and tightened the bolts as har as i could and it was rotating fine , i could rotate it with a spaner then i put number 2 in. It went down the cylinder alright but when i tightened the bolts for the rod it when like before but when i lossen the bolts and only hand tightened them it was rotating fine again . Is it the rod bearings then ? do i have to replace them?
thanks

The rod bearing is the problem, but if you are using the old bearing in the same spot, you may be simply overtorqueing the bearing.

Make sure you have plenty of lube on the beatmrings and the bearing is properly seated.

Torque should be 85.417 newton metres/63 ft. lb. or, if you don't have a torque wrench, 'pretty snug' with a 1/2" ratchet.

Just out of curiosity, how much does a set of bearings cost?

This sounding like spending a lot of time to get an engine torn down, and then not replacing "easy to get to now" parts. In my mind, new bearings while you have it apart and have access to them is always the best answer if you can afford them, and they are available.

When I was young and dumb, I replaced just a clutch disc once. Turned out the clutch disc had gone bad because the pilot bearing in the crank was bad, which allowed the disc to hang down enough for the edge to drag between the pressure plate and flywheel.

So, a couple of months later, the pilot bearing had failed completely. I was back in taking out the transmission to get at the clutch, to replace the pilot bearing, the pressure plate and disc. And the angled input shaft had tweaked the input bearing on the transmission and front seal, enough that both of them needed replaced. Ended up walking to school and work for three weeks, to get enough money to buy the new parts and get the flywheel turned. Ended up spending a couple of hundred dollars extra, and walking a lot of extra miles, because I didn't replace a $3 bearing when I had access to it.

There used to be "refresh kits" for many engines, which consisted of new rings, bearings and gaskets.

Hey
Sorry for the late reply .
If i tighten it them like you said it's quite stiff but should be alright .
Well thing is we're going to sell the tractor but like i saw it's worth much more running than not. What do you guys think? is it worth it ?
also it's good working experience sort of and i like doing it . also i've just really really stupidly split an injector nozzle but tightening it too much is it worth getting a new one or can i somehow seal it and if it works buy one then ?
Thanks for the advice and help

I've figure it out . I had very stupidly put them on the wrong way round .
