124in. Engine Build (page 1)

This illustration shows the actual torque sequence, and case hardware location. Locations G,F,B,E are alignment studs...they are 3/8, even though the threads are 5/16 fine...lube these before installation. They generally require tapping in, and keep the case halves aligned properly. note that the torque sequence does not follow the lettering pattern.



This just shows the motor finally up in the stand, and tightening the case studs and hardware. I usually do this in steps, following the sequence.... recommended torque is 12 ft-lbs for the center bolt, and 18 ft-lbs for the rest...so I usually halve each spec and go around the sequence twice...and also check the studs' torques on the other side of the case... I use red loctite on the 5/16 bolts and alignment studs and blue on the center stud.



Here are the alternators mounting holes...4 circled (actually only three visible in purple hold the stator. Use red loctite on these screws.The hole circled in green is for a set screw to hold the stator plug in place. When installing the alternator...just run this screw in flush, or it may pierce the plug and short the two wires together. This is actually kind of a common mistake.



Here's the Jim's machine tool for removal of a cam bearing, because these cases were polished with the bearing installed, I always replace the bearing for fear of polishing compound. Always replace with the Torrington bearing OEM# 9058. This is the superior bearing that fits 58-99 model motors, and it should be replaced with any cam change.



This shot simply shows the installed location.



Here we have the tool tapped into the bearing, and the pulling of the bearing.



My installation tool, and old camshaft with the gear removed, and the rear thrust shoulder and lobe ground down slightly. I just slip the bearing on the end of the cam shaft(NUMBERS OUT), and tap it till it hits the cases shoulder in the journal.



This basically shows the hole for the tappet screen, it is installed flange down in the hole, with the spring placed over top of the screen. This screen filter the top end oil supply...exiting the pump, and before the lifters. It should be periodically cleaned at oil changes...and is the first place to look when your top end starts making any kind of noise...teflon tape scraps, and dried silicone sealant will often end up here. So I always check it after a motor has been first run. I also prime this hole repeatedly at startup. A gauge can be installed in this hole...with CCI fitting # 270062. I have also labeled the oil pressure switch hole, or sending unit hole, or top end supply hole (retro pans, shovels)...this can be plugged, or a gauge could also be located here. This hole is directly in line from the tappet screen, and after this hole...the oil turns right, off to the tappet blocks and lifters.

WOW! I'm about to contribute to CC again. The value of info like this... If everyone on here could pony up just $10.00 or so once a year... You'd all be getting a great value AND BigB would be able to afford all the redundant goodies so we would never go down...
