x-15 liner shims - Ricardo - Yesterday
ive searched around a bit but havent seen anything specific to what im trying to understand so if theres already a post on this i apologize.
x15 started putting compression in coolant so i tore it all down and found fire ring on head gasket busted out on cyl 3 cleaned everything up and had from .009 to .003 liner height pulled liners and measured the block and had readings from 4.7260 to 4.7275 (monaco height block zeroed for 4.7240 and a reading of -.002 to -.0035) this seems like a lot less variance in height to me does the captive shim take most of the wear?
per a previous post on here seems to be ideal block depth of 4.740 giving a finished height of .015?
regardless .009 is too low so ill be cutting it for .020 shims to a depth of 4.740 i believe is correct
My question is the captive or factory installed shim thats installed on the new liners is that to be used plus the additional .020 shim to achieve this height?
From cummins bulletin TSB120249
"NOTE: It is acceptable to install a factory shimmed cylinder liner assembly, on
top of a service shim, on engines that have had the cylinder block counterbores
machined."
Stainless shims over brass shims?
first isx rebuild for me can rebuild a yellow one with my eyes closed but this is all new to me so any input is appreciated
