how to time the cams.???
is covered best by a real ISUZU FSM book
2nd best is alldata.com
id not time a lawn mower with autozoned. data. nor the books they sell.
there are lots of issues, doing this.
like how to lock cams up.
if engine is interference, its listed as such.
- 2.2L Gasoline Interference
- special rules on tensioning , right.
etc.
quote. (assumes not snapped belt now or stripped) do say....?
- Disconnect the negative battery cable.
- Using a box-end wrench on the drive belt adjuster, turn the adjuster clockwise and remove the drive belt.
- From the left rear of the engine compartment, disconnect the 3 electrical connectors from the chassis harness.
- Remove the crankshaft pulley-to-crankshaft bolts and remove the pulley.
- From the front of the engine, remove the nut and the engine harness cover.
- Remove the timing belt cover.
- Rotate the crankshaft to position the timing marks at Top Dead Center (TDC) of the No. 1 cylinder's compression stroke.
- Remove the timing belt tensioner adjusting bolt and the tensioner from the engine.
- Remove the timing belt.
- install is next
- Install the timing belt tensioner and finger-tighten the tensioner bolt.
- Inspect the timing marks to be sure that the engine is positioned at TDC of the No. 1 cylinder's compression stroke.
- Using tool J-43037, or equivalent, place it between the intake and exhaust sprockets to prevent the camshaft gear from moving during the timing belt installation.
- Install the timing belt.
- Position the timing belt to ensure that the tension side of the belt is taut and move the timing belt tension adjusting lever clockwise until the tensioner pointer is flowing.
- If installing a used timing belt (used over 60 min. from new), the pointer should be positioned approximately 0.16 in. (4mm) to the left of the "V" notch when viewed from the front of the engine.
- If installing a new timing belt, the pointer should be positioned at the center of the "V" notch when viewed from the front of the engine.
- Torque the timing belt tensioner adjusting bolt to 18 ft. lbs. (25 Nm).
- Install the timing belt front cover and torque the bolts to 53 inch lbs. (6 Nm).
- Install the engine harness connectors.
- Install the crankshaft pulley and toque the pulley-to-crankshaft bolts to 14 ft. lbs. (20 Nm).
- Move the drive belt tensioner to the loose side and install the drive belt to its normal position.
- Connect the negative battery cable
got all that?
during the above do not let the valve hit the piston tops.
do not crank engine until 100% dead sure its timed right.
or BOOM. bent valves.
one guy found engine with no interference at all, later found all 12 bent over. and useless, but sure dont hit. now.... LOL...
just a warning, about DOHC engines, "respect them"
i build it back (was dead before) and then do a by hand cylinder leak down test, and if that fails, the head comes
off, i never crank a suspect engine (or dead), until i do that.
