Seeing as to there are no ideas forthcoming concerning my three problems re the liners, the Golden Rivet and the B.S.B. Welders detection tool it rather reminds me of my T.T.T.T. article and as such I do fear that the B.C. ( bus conducters ) title may be lurking out there somewhere for some folks who perhaps have the C.R. ( control room ) addiction as things are nowadays down below.
In an effort to distance ourselves from this ungainly B.C. title I feel that by relating what should be a well known job to all the correct answer will be arrived at concerning the B.S.B. Title.
Anyone worth their salt must have done this job somewhen and as such has experienced what sometimes invariably follows re problems encountered en route.
Picture the scenario, a stern wind of medium strength when underway causes soot/smut deposits to be deposited on the decks.
By the process of elimination ( as in common rail diagnosis ) a diagnosis reveals the culprit to be a particular genset.
But is the smoke L.F.O. Or Lube oil?
Monitoring the situation it is discovered that a small amount of lube oil is being consumed by the engine concerned.
So out with the slide hammer, remove all injectors, pump up and pressure test ( just for the hell of it on the injector testing M/C ) and in with the compression tester.
A check on all cylinders reveals all over 400 p.s.i. and no piston slap previously being heard it's time to replace the injectors annealing or renewing copper washers as necessary.
So it's off with the rocker covers and peering in between closed valves with the coil springs in the open mode thus revealing all it's evident that the valve stem oilseals have let go, they are split and perished thereby allowing the lube oil apon its return to fall down into the guides and be combusted in the bore, up the smokestack and thereby onto the decks.
A look in E.R. store reveals that the tool to enable you to change the valve oilseals without removing the head /s is awaiting your useage.
So carefully locating the fulcrum ( remembering here moments about a point ? ) and the leverage applied reveals the Two cotters in all their glory.
Now can the problem arrive of removing the cotters without allowing them to drop.
Years of hammering the cotters up into the retaining top cap taper together with red hot oil and some carbon can cause the cotters to become difficult to detach from the stem.
By using your pinkies to attempt to separate them is not to be recommended, those dual valve springs don't like being compressed and remember all components here are of a high grade carbon steel.
So unless you don't mind having the top end of your pinkies sheared off it's out with that small screwdriver.
Now comes the dangerous and alas often encountered job.
Requiring quite some effort of twisting moments of the screwdriver sometimes one collet will fly off at a rate of knots invariably landing down below, underneath that head web casting and sat atop the block.
Forget that 12 inch studding with a blob of grease on the end, that's dangerous and often sends the cotter off down the pushrods tubes to sit amongst the cam followers. ( No shaky hands here remember )
Deep shit and we certainly don't want to go there.
I have had one of those dentist mirrors on the end of a 12 inch bendable cable which will stay in the position you have bent it in over the last 25 years or so and should the cotter be lurking out of sight perhaps the similar tool with three expandable claws will help.
The jaws akin to being like a three legged extractor which when let go will grab the collet and thus secure it in the jaws securely.
There is however a much more suitable tool to ensure safe removal of the rogue collet, I have had one since 1960 and for sure this is one tool you never, ever want to lend for certain it's such a life saver you will never, ever see it again.
Can't really recall the percentage collet leap off down below failure rate throught my years of head overhauls but stabbing in the dark perhaps it's possibly in the order of 10% or so.
So back to the B.S.B. Detection tool question, what's the name of this tool for it comes from the same family only this is " the bar version ? "
So come on R.R. And bat the ball back to me, it's lonely out here?
