I think the damage on crank shaft was not to bad. #17B sz2

Now the situation is like this:

DSC02103

But it was as next:

DSC02099

I was using as first 600 water sanding paper and to finish 1000 (check the table on the bottom  for bold text). Data for  600:  25,8µm= 0.00002580000 m and for 1000  0.0000183 m

DSC02104

As a reference to get feeling how much the scratches damage in material was i am making next calculations. Under the red elipse (picture below) mark is next standard dimension. And  the  difference between dimension is  0,01 of inch what is equal to 0,25 of milimeter = 0,00025 metre. And i was grinding down as first with average particle diameter of 0.0000258 m. What is 1/10 of difference. I did use  amount of paper which i am holding on  picture above. I hope i did  not grind to much to compromise clearance which i will have with new bearings. (Exactly How much did i grind i will know when i will put new bearings and compare this one with others).

And how did i get to the Perkins part serial number? Googling next page

from bearings number:

And what is the status now:

DSC02121

 

On bearing  above you may see horizontal line which is checking from clearance tape thread:

DSC02117

The conclusion my clearance is 0,003 of inch  now. What is to much. Acceptable tolerance is 0,002. And also there are deep scratches in bearings. I have to get me new one. I did took a risk and  because Steve was coming from USA  2 weeks  ago and got  him to bring me the standard bearings.  I did lost 70$, because i need  -0,01 bearings (the first size after standard check picture above). I am looking to get them in Rio dulce now.

To ilustrirate where am i working:

I need to find why oil pressure is low #16B sz2

 

It looks that this brake will be longer as it was meant.  I want to change. But i do not know how. And i am not doing anything to find it out. I am just waiting.  It will come out by itself. Probably.

In this days i am slowly getting  me ready to solve the problem with low oil pressure.

Now I have enough space to work under the engine. Click on the photo below to see the red arrow.
