Hey Curtis. Not sure how cool, but we'll know a little later today.
my new tube of threadlocker arrived last night and I put some on the top of the shaft and installed it... supposed to cure 24 hours, but I can't wait
so, I assembled it:
and installed the seals (SSOOOOOOO easy with the new seal tool!) ..note I am re-using the sorrento seals, they have a handful of months on them and for my purposes, they are slightly stiffer than the silicon cafelate but softer than stock seals, so represent a good halfway modulus to gather data about sealing pressures (at least that's my seat of the pants opinion)
After seal installation and pushing it down into the group head... I was holding my breath. I had to guess at the land depth and left it rather 'high' at 1.640" diameter, if its too tight it would be a simple matter to take the piston out to trim it down slightly deeper... it was very stiff going down, but went in smoothly after the first seal made a slight noise something like you'd hear in your proctologist's office...
Buttoned it up, machine is heating up now. Will get back to you in a bit. I took one lousy pic from underneath, wow that piston is tight fitting now! i have to scrape away the excess lubricant, but it looks much, much closer to the walls than the stock piston. Also, no holes in the face!
