A trick would be to put a breaker bar on the bolt and against the passenger frame and use the starter to break the bolt loose. You just "bump" the starter and use it get the bolt loose. If its a manual trans, when tighteneing the bolt, put it in 4th gear and lock the parking brake, and torque the bolt to 90lbs.

Replacing the waterpump on a 1992 Isuzu pickup with carbureted, timing BELT 2.3 litre four cylinder engine. Do i need to remove the crankshaft-pulley center bolt to be able to pull the timing belt cover...


pretty safe on this old engine ,put socket and bar on the bottom pulley bolt and crank engine so starter motor cracks the bolt for you ,these older engines have a keyway on the pulley so no problem do not do this on new cars as pulley has no keyway and once the pressure is released the cambelt doesnt move and the valves go clonk

Timing belt


TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o'clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.

1989 Isuzu pickup how to align timing marks on cam and crank?


The Isuzu is a strange animal-when you do the timing belt you set it with #1 TDC "BUT" the distributor is timed with TDC #4 I found this the hard way and finally had to buy a cd with the procedures on it. Send me an e-mail address and I will forward the associated pictures &
info to you.

Key Cylinder removal


Lock cylinder & keys is about $90. Switch alone is around $45 with wiring harness. Don't know if switch comes with a new lock cylinder. Thought I had to replace mine, so read up on it in Haynes Repair manual before jumping in. Just did this today. Took my switch apart, cleaned it - nothing wrong, put it back together. Doing that, I didn't have to remove the lock cylinder, so I can't offer hands on with that.
My '89 pickup does not have shearhead bolts as described in the manual - guess some models do. Here's what the book says (with my add-ons):

- Disconnect neg. battery cable
- Remove steering column cover (bottom half - 5 phillips screws)
- Unplug ignition switch wiring harness (I didn't do this - must be back up under the dash somewhere)
- Remove the two ignition switch/steering lock mounting bolts (phillips) If shearhead bolts, cut a slot in the head with a chisel, then use a flat blade screwdriver to remove. You can get to these two screws by turning the steering wheel first one way, then the other. (Once you get in there, you'll see removing it is not a big issue)
- Remove switch assembly from steering column.
- Install is reverse of removal procedure
