the BEB is an issue to be aware of...

BEBs, con rod crank bearing.

Been in touch with a local mud member who is doing the long block replacment for a BEB that failed and took out the crank.

He will be sending me pics of the crank big end bearings, he claims thier is some wear showing, although they are much larger and distribute the loag to a much larger area they do seem to be showing signs of wear.

Rob, this would make sense since the wear in the BEB will allow particles to be circulated into the oiling of the crank bearings thus leading to premature wear...

i would call bull shit on that claim, the only concern i have heard is the one mentioned above... of course serious abuse, over boost etc could cause crank failure...
the power steering pump is at the front of the engine so i am suspecting something got dropped inside and jambed the gearing and busting the crank...

just a assumption...

where are you located? a new crank will not be cheap but if all it did was bust the crank then it shoudl be fixable. i would want to know if indeed the crankis busted or if one of the BEBs spun and locked up the crank, that repair is huge money...

I sent a used one to G&S last month, give them a call.

If you want new email me and I will figure something out. Light enough to just mail over I think?

Yup, What Dave said. We just got one in. Have not inspected or mic'd it yet. Still covered in packing grease and plastic.
Send me a pm or email if you are interested in it.

That'd be me with the longblock dismantle.
Actually the bearing wear is NOT particulate wear as you'd see in an engine w/o regular oil changes or contaminated oil. Rather it is the same patchy delamination that we're seeing on the rod bearings. Sorry to ruin everyone's day but it looks as though the 1HDT mains were scat as well. That said, they don't undergo the abuse that rod bearings do and that's maybe why we're not seeing issues yet but, I think we eventually may.
I will get pics to you Rob. I'm just out of town for this whole week.

so you are saying that no particles were circulating through the oilling system? if this is the case then an oil analasis wouldn't have let you know the bearings were on their way out...would it?
shouldn't it be that in the later stages delamination "chunks" of aluminum should let go?

for this i am reaching for answers since i have not had this happen to me...

A good used crank will be a $1000 or so and then it really needs to be stripped down an examined thoroughly which is 2-3 days labour plus reassembly nd installation.
Then there is a chance it will need more parts or maybe even a complete rebuild.
It takes a lot of force to snap one of those cranks.
IMO you would need to have $10k set aside on top of the purchase price.
Maybe youll get lucky and it will be half that.
And yes it can be made reliable at a price with someone who knows these engines.
If I was a US citizen I would convert my 80 series gasser with a good used diesel.
