Glearance
1.To check main bearing-to-journal oil clearance.
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main jour-
na l.
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flvwheel will flaften the plasti-
gage further than just the torque on the cap bolt.
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
time,
Reinstall the bearings and caps, then torque the
bolts.

lf the plastigage measures too wide or too narrow,
(remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. Install a new. complete bearing with the same
color code {select the color as shown on the next
page), and rechsck the clearance.
CAUTION: Do nol fil€, shim, or scrape the bearings
or tho cap3 to adiust cleatanc€.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again
NOTE: lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.

PistonsGrankshaft
lnstallation
Before installing the pistons, apply a coat of
engine oil to the ring grooves and cylinder
bores.
lf the crankshaft is already installed:
. Set the crankshaft to BDC for each cylinder.
. Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.
. lnstall the ring compressor. check that the bear-
ing is securely in place, then position the piston
in the cylinder, and tap it in using the wooden
handle of a hammer.
o Stop after the ring compressor pops free, and
check the connecting rod-to-crank journal align-
ment before pushing the piston into place
. Apply engine oil to the bolt threads. Install the
rod caps with bearings, and torque the nuts to:

lf the crankshaft is not installed:
. Remove the rod caps and bearings, install the ring
compressor, then position the piston in the cylin-
der, and tap it in using the wooden handle of a
hammer.
. Position all Distons at top dead center.

lnstallation
Before installing the crankshaft, apply a coat of
engine oil to the main bearings and rod bearings.
Insert the bearing halves into the cylinder block and
connecting rods.
Hold the crankshaft so the rod journals for cylinders
No.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rod
journals into connecting rods No. 2 and No. 3, and
install the rod caps and nuts finger-tight.

Grooved sides faceoulward.Botate the crankshaft clockwise, seat journals into
connecting rods No, 1 and No.4, and install the rod
caps and nuts finger-tight.
NOTE: Install caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
page 7-11), then torque the capnuts. Apply engine
oil to the bolt threads.

set idle rpm in gear to specified idle speed. lf still no good, adjust motor mounts as outlined in enginesection of this manual.
lf the clutch pack is seized or is excessively worn. inspect the other clutches for wear, and check the orificecontrol valves, CPC valve and linear solenoid for free movement.
lf the linear solenoid is stuck, inspect the clutches for wear.
lmproper alignment or main valve body and torque converter housing may cause ATF pump seizure. Thesymptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
lf the l st clutch feed pipe guide in the end cover is scored by the mainshaft, inspect the ball bearing forexcessive movement in the transmission housing. lf oK, replace the end cover as it is dented. The o-rinounder the guide is probably worn.
Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged. lf the 4th feed pipe is danFaged or out of round, replace the right side cover.
Replace the mainshaft if the bushing for the 1st feed pipe is loose or damaged. lf the 1st feed pipe is darn-aged or out of round, replace it.
A worn or damaged sprag clutch is mostly a result of shifting the transmission inthe wheels rotate in reverse, such as rocking the vehicle in snow.
or E position while
Inspect for damage and wear:
1. Reverse selector gear teeth chamfers.
2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.
4. Differential pinion shaft for wear u nder pin ion gears.
5. Bottom of 3rd clutch for swirl marks.
Replace items 1,2,3 and 4 if worn or damaged. lf transmission makes a clicking, grinding orwhirring noise,also replace mainshaft 4th gear, reverse idler gear. and countershaft 4th gear in addition to 1, 2, 3 or 4.lf differential pinion shaft is worn, overhaul differential assembly, and replace ATF strainer, and thoroughlyclean transmission, flush torque converter, cooler and lines.lf bottom of 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and final drivengear.
Be very careful not to damage the torque converter housing when replacing the main ball bearing, you
may also damage the ATF pump when you torque down the main valve body. This will result in ATF pumpseizure if not detected. Use the oroper roors.
Install the main seal flush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out, it will block the fluid return passage and result in damage.
See flushing procedure, page 14-187 and 188.
lf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
lf the l-2 shift valve is stuck closed, the transmission will not upshift. lf stuck open, the transmission hasno 1st gear.
lf the znd orifice control valve is stuck. inspect the 2nd and 3rd clutch oacks for wear.
lf the 3-4 orifice control valve is stuck, inspect the 3rd and 4th clutch oacks for wear.
lf the clutch pressure control valve is stuck closed, the transmission will not shift out of 1st gear.
lf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
Inspect the frame for collision damage.
