SIS is kicking my but on this one, keeps coming back "Sorry, but there are no equipment configurations that match serial number '48A12788"I am looking for the torque specs for the heads & the measurements for adjusting/checking valves on a D7E s/n; 48A12788
Anyone out there have that info?
TIA, Slim

Guess this might be too old for Cat to have put it into SIS. Not sure which engine this had but as you say "heads" I'm guessing it's not a 3306! Hopefully someone who has access to older info can help.
Old magnet, That is what I was thinking but do not have access to and of that old of info. The key for me was when he used the plural "heads"!Engine is a 4-cyl D339
Exh 0.020" (Hot) 0.018" (Cold)

Looking like single layer steelIf I remember correctly Cat always stated DRY. On some engines with steel sheet gaskets we would prep the block with a lite coating of Copper Coat gasket sealant to compensate for wear marks(heads shift on the block while running making erosion marks). What style gaskets are the replacements? Single layer sheet, crush sheet steel or composite steel/fibrous?
If I remember correctly Cat always stated DRY.
checking/measuring liner projection may be tricky..... Any tips on that?I recommend this stuff (both sides of gasket)...... Be sure you have proper liner projection 0.004 to 0.008" with liner clamped down.
Same here, this older stuff is before my time, so I know there are people out there with information that is quite different than how current things are done.Interesting point. I have also always assembled head gaskets dry. However I was building a C15 last year and lo and behold a note popped up on SIS saying to use gasket sealer on the spacer plate gasket. This information is definitely new. If I get time tomorrow, I will try to find it again.

Cmark,
Hope you don't mind me looking it up for you:
4C9505 sealant.
Surely it's not too difficult to find a piece of solid bar that will span between 2 cylinder head studs/bolts (bearing puller spreader bar maybe...? Use that to pull the liners down and a set of feeler gauges under the bar to the top of the cylinder block to measure the projection.checking/measuring liner projection may be tricky.....

Called CAT, they said it's discontinued.Cmark,
