My Diesel Let me down!

[smithy010]

I haven't examined the big end journals carefully yet, but assuming the journal is ok, is it a bad idea, instead of removing the crank, to just remove each main bearing cap one by one and examine each main bearing? I don't really want to pull the engine.

Also, anyone in sydney got an internal micrometer they'd be willing to loan me for a week?

Update.

I've been too lazy to take photos as yet.. The interesting thing is that i have measured the top ring gaps, and it is 0.7-0.75mm, which is certainly worn, but by no stretch of the imagination is it "out of spec"..

I have examined the crank, and there is a tiny scratch on it, about 1/3 of the way around, and on the left hand side of the journal. I reckon i'll be able to polish it out with a bit of wet and dry.

So, to stop it spinning bearings again, i'm going to measure up the no.3 conrod to check, and possibly replace the rods.. Does anyone think it could be troublesome replacing rods with other second hand ones? I guess if they are the right size for the little ends, they should be ok, right?

I'm waiting for a set of mics to finish on ebay, and then i'll be able to measure her up.

I have a little newfound enthusiasm since the petrol price has risen, and also since i went to the nats and had a yarn to the diesel boys (including aydan's old man in his GLD with light truck tyres on it). Sick!

All good

Con rods

OK to mix and match conrods, mate. Petrol ones are OK. Just make sure you check for bearing crush when reassembling.

Cool. Cheers Cetane.

Yep, i'll plastigauge them all. Shouldn't be a problem.
