Yes, take off the bearing cap that's the easy one. A copper rivet of appropriate size is placed in the oil drilling in the crank and turned so the head of the rivet pushes the top half shell around till it can be removed. Replacement is the reverse. Remember there is a location notch on the shell so turn the crank in the right direction

Pity you didn't get the numbers off the shells, Ebay STC4299 (Think they are standard) £21.89

Great reply, many thanks! sounds simple enough even for me to do, what pitfalls if any could be encounterd?

Oil dripping into your eyes, do them one at a time as I posted and turn the crank at least one rev before you move to the next. Make sure the shell is seated and the cap torqued correctly. If you do it before the 27th you can pm me if you need any help, or my number

should be a walk in the park for a man of your talents Ant, i like Alans tip with the copper rivet, when i did shells insitu i pushed them round with small screwdriver, biggest problem is having to do everything upside down

Many thanks for the kind offer Alan, I won't be able to do it for a few weeks now, but I really do appreciate your offer of telephone assistance!!

Have to say I am fed up with having to undo sump bolts....of the whole job I did last night, the worst part by far is the working overhead lying on yer back with a ratchet and long extension bar undoing all those sump bolts!!

Appreciate your words of encouragement!

cordless drill works well on lots of small bolts gives your arms a break

bloomin hell ant you've been busy ps shells are easy & for the mo just treat it to some slick 50 until you get round to changing them m8

I would get a tube of 'Graphogen' to smear on the crank journals as you fit the new bearings.

It keeps the bearings lubricated when you start the engine until the oil pressure gets up and washes it out.

Or some STP which does the same job for half the price. Stick what's left in with the new oil to give the new shells a decent start in life.

id be checking journals ,and changing my oil more regularly,unless its done star ship miles in which case the shells wont be the only worn bits

Yep for sure, when you find shells as knackered as that it's time to get the mic out.

Yep exactly, you might just get a few more miles with new shells but not many. Wonder if he has considered EP140 for the sump oil? The oil pressure would be wonderful for a while at least.

Yep if they are going it's strip down time. Happy days.

tomcat59alan · Nov 19, 2014

True for the big ends, but I thought it was a recovery job. Hopefully mains will cure the pressure problem. If it doesn't then it's engine out and a regrind. The regrind ,new shells, rebore and pistons for the straight six was £500 a couple of years ago

Unless he sends the engine to Dr Evil who may do it for less.

if ones gone generally the rest have including big ends , if caught in time a crank polish is often all thats needed, i wouldnt want to rebore a 4 or 4.6 v8 if i could help it , an uncracked 3.9 often cracked soon after rebore im my experience
