Crank Journal Bearing condition...

<< < (2/3) > >>

philward:
Welcome to the forum - I agree with the previous posts and would change those shells.

Oz350Four:
Thanks folks for the feedback / advice...
Now to work out what colour / number I need and try and source them.
Stay tuned, I will no doubt have further questions.
And, just to keep a few of you busy I've posted a picture of handiwork by the previous owner so you might get an idea what I'm up against.

Doesn't look too bad inside, agree with old oil used in condition of shells. 

If you're not familiar with 400 four, that lower enging mount (rhs in photo) and right next to the main oil feed to filter housing, is the one that gets punctured when people use too long a frame mount bolt.

Usual mode of operation  :) is when removing a crash bar that's used a longer bolt,  that when put back in without bar, goes straight into the oil feed to crack it. Make sure you've got the right one to avoid grief.

Welcome to the forum too.

Also a very good appreciation of 400 four rebuild and worth a read through http://www.sohc.co.uk/index.php/topic,14049.0.html if you've not already seen it.

Thanks K2-K6,
I had known about the old long bolt in the mount issue... but did you notice the oddity in the crank case bolts...???
I have started reading Nurse Julie's build thread... quite detailed I must say. I wish I had half the tools / facilities / knowledge at my disposal..!!  :D :)

K2-K6:
Can see the extra dome bolt, has the previous owner put a stud in there?
