It has finally arrived!!
I took delivery of a new Jkson 8/1 and I am now stripping it down to clean it out as per George's CD. (and Quinn's excellent kit engine report).
I have to say that despite hours of reading and studying the CS design, nothing prepared me for the the great sense of satisfaction when I first took off the inspection cover and beheld that massive crank and con-rod!!!
.
WOW. This is some seriously heavy duty powerplant!!
The sump was pretty clean and the crank case internal paint job supurb....but there was a little grit on top of the piston and on the Head Gasket. Also a tiny amount of scoring from grit inside an otherwise shiny new Big-End bearing. Also a slight horizontal scratch on the crank journal which I will polish out using the "shoe-lace" method.
I am not taking any further chances on grit so I am completely tearing it down to clean, and now I have come across 2 issues that I need advise on......
1....
How do I remove the piston pin? That thing is sure in there tight !!!
2.......
George says to high pressure water clean the inside of the crankcase. Will this actually remove the paint? ( my crankcase is finished in red oxide undercoat type paint)
Or should I use the Quinn method of a 24 hour "Drain-o" bath.
(I wonder what he did with the drain-o water mix when he was finished???).
It is just that the paint job looks so darnn smooth.
I have poked around and have found no sand pockets at all. Am I beeing fooled by the smooth paint?
If a water blasting will remove it I will do that. The "acid" bath at this stage is not really an option for me.
Other than the over use of body filler, I am pleasantly suprised that the machiening of the case/block/head seems pretty good and better than I expected.
Thanks in advance for any advise
Matt
