final turning torque

-8 cylinders--40ft lbs -6 cylinders --30-ft lbs -4 cylinders--20 ft lbs -add 10 ft lbs for rope seal

non-reconditioned cylinder walls use what rings and why

-cast iron rings -will seat faster and conform better to imperfect cylinder walls -cheaper -shorter lifespan

methods to adjust shaft system

-check for different length push rods -use a shim or shaft system

adjusting valves for non-adjustable hydraulic lifters

-check plunger height (not bottomed out or against the retaining clip) -plunger height should be centered

adjusting valves for mechanical lifters

-find lash specs -turn adjustment to obtain correct clearance between the rocker arm and the valve butt

lifter cleaning

-flush externally with clean solvent -disassemble each lifter, clean thoroughly, lubricate and reassembly -don't mix parts

oil pump priming

-gears should be coated/lubed with heavy oil before cover is put on -primes pump so it will draw oil from the pan

oil pump inspection

-install new oil filter -install reminder of EOS and fill crankcase to proper oil level -install oil pressure gauge -drive oil pump with an electric drill in normal direction of pump rotation -oil pressure should be about 40-60 psi slow rotate crank several revolutions while prelubing

oil rail installation

-installed top rail and then bottom rail by hand -do not overlap -butt ends together

bearing noise

-knocking -clatter -intensity and sound varies with engine load

engine noise

-knocking -clicking -clatter -clunk -whine -rattle -clacking

lubrication of bearings upon assembly

-lube all bearings with engine oil supplement -lube the inner diameter of the bearing for the main caps- not outer diameter or saddle/cap area

crankshaft inspection

-measure mains and rod journals for dia, OoR, and taper -measure crank for alignment -inspect finish on journals -inspect for burrs on journals -inspect thrust surfaces -inspect seal areas

fully reconditioned cylinder walls use what rings

-moly rings----good for heavy load or high RPM (most passenger cars) -chrome---especially good in dusty conditions

oil pressure loss indicator

-normal bearing clearance drip rate is 20-150 drops/minute -high drip rate may be caused by the drilled passages to a rod journal being aligned with a spit hole

possible causes of turning torque increase

-piston in backwards -no end gap -bent rail -no rod bearing clearance -no piston clearance -frozen or tight wrist pin -dirt in or behind bearing -bent rod -carbon in ring groove -tapered cylidner wall -no rod side clearance -cap reversed -rough bore surface -OoR rod bore

how to use plastigage

-place strip across dry journal -install cap and bearing with thin film of oil -torque -remove caps and compare to the scale -tapered strip indicates a tapered bearing clearance

methods to adjust ball and stud

-replace nut with aftermarket self locking shouldered nut -check for different length pushrods

adjusting valves

-rotate engines to TDC Compression #1 cylinder -rotate engine clockwise next to mark on tape (check or adjust plunger height (hyd.) or adjust valve lash (mech) for the 2nd cylinder in the firing order) -rotate to next mark (check or adjust 3rd cylinder in firing order) -continue process until engine has made 2 complete revolutions

cylinder wash

-scrub cylinders with a soft rag and hot soapy water -rinse and blow dry -scrub again with clean rags and detergent oil -cylinder is clean when it passes a white glove test -cover block to prevent contamination

ring installation order

-top rail -bottom rail -scraper ring -compression use

adjusting valves for adjustable hydraulic systems

-turn adjustment in until the pushrod looseness is just depleted -turn nut slowly, counting the turns until the plunger just bottoms out -back the nut half way -make sure plunger is not bottomed out

turning torque with piston installation

-turning torque should not increase more than 5 ft lbs with the addition of a piston -if it does determine cause

methods to adjust pedestal stand

-use a shim or shave stand -check for different length pushrods

if block only requires deglazing then

-use drill speed of 300-500RPM and 220 grit stones -move drill up and down fast enough to achieve a 30 degree crosshatch -lube cylinder with 50% oil and 50% mineral spirits -clean stones between cylinder

if bearing decreases to less than ___________bearing damage will occur

.0001

bearing clearance spec

.0005-.0025

thrust bearing clearance

.002-.012

if cylinder exceeds __________ after deglazing and honing the cylinder should be bored and have an oversized piston

.006

ring gaps should be no closer than__________apart

2" or 180 degrees

what 3 sizes of plastigage are there

3 sizes: green .001-.003, red .002-.006, blue .004-.009

ring gaps cannot be on what surface

the major and minor surfaces

what position would the piston have to be in to have both lifters on the base circle simultaneously

TDC Compression

one ring installed upside down will increase____________

oil consumption 30-40%

what position should the plunger be in while the lifter is on the base circle?

the plunger should be centered
