found thrust washers in pan of 165?

how did the thrust washer fall out? would this have any relation to oil blowing out the exhaust? Rods and pistons forced to sideways because of the huge end play? Engine runs good and appeared to have been rebuilt recently.
 
Not uncommon on Perkins engines. A good machine shop can help you out. I never could understand why Perkins didn't use flanged Main Bearings. I guess there must be a reason.
 
Hi Phil,
Good point. But there again if they had we would have nothing to speculate about why they didn't.
Thrust washers falling out can be due to them being fitted the wrong way round or down to an excessively worn journal face on the flange. Perhaps whoever might have rebuilt it didn't notice the excess end-float or perhaps it was a case of "not my problem, if something happens".

Thank you for the reply. So, the wrong way around would mean the hard none babbit surface rubs on the crank journal face and wears the face?
If the end float was maybe .050", the washers could drop out?
 
As I remember it the gap was small, less than .010 but cannot remember the exact gap. I cannot cannot confirm it but I have been told that riding the clutch causes premature wear and failure of the thrust bearing.
 
Hi,
Crankshaft end-float should be between .002 and 015".
It is a debatable subject but in my mind riding the clutch will certainly cause thrust and release bearing wear. Many tractors require the clutch pedal to be pressed in order to start. This puts load on both components when the oil is cold as well as increasing the load on the starter motor and battery.

OK, so it's not a lot but it exists.

Likewise I would never have a car that stopped the engine automatically if waiting for lights etc. It may be environmentally friendly but who will pay for my new starter motor when it wears out after being operated 3, 5, or 10 times more than it would have otherwise?

I understand what you are saying David, but I was referring to having your foot on the clutch pedal all the time while working the tractor. I've seen people do it.
 
Hi
It may of had the wrong thrusts put in at rebuild. I just did a 2135 industrial with a 3 cyl.
It had to have a new crank. when I put the motor kit supplied bearings in, The end float was horrendous! they would of fallen out, had I not been very thorough with checking measurements like some don't.
I had to order a thicker set of washers to get the end float right.
So maybe the wrong thrusts is your problem here.
