H23 92 Prelude - Crank Pulley fell off

I didn't TORQUE the bolt over the crank pulley, and after two weeks of driving, my bolt, followed by crankshaft ;/ underdrive pulley fell off about 35-40 mph. The car died instantly, ran over the pulley, alternator belt was found a hundred feet back intact. Tried to start the car, and it would only spin really fast. towed it home. Upon pulling off the balancer pulley, I saw that the key had bent out, and crank key hole was opposite the balancer pulley.

What damage could I / did I do??? There appears to be no damage other than the missing pulley and bolt. Got a new pulley, key and bolt, about to put them on. Any ideas???

    I set everything at TDC, cam gears, crankshaft and balancers, front and rear. Lines up perfect everywhere, including flywheel. It is a 5 speed m/t btw. I just tried firing it up, and it does the same thing. I hear the fuel pump come on, I know I have spark, and gas. Checked the main relay.

    Here's a short video of the sound it makes when I turn it over, and it will NOT fire up.

    To be even MORE precise:

    When I turn the ignition on, I hear the fuel pump prime, replaced the main relay cause it was free, and it works, but when I hit the ignition, the starter whines as in the video above. The engine spins, but will not fire at all. All belts, cams and pulleys turn. So I am guessing the starter is engaging, I'm at a complete loss of ideas now.

    So after weeks of eliminating stuff, I discover the fuel lines were smashed pretty good when the pulley fell off. In two places. Would this explain why it won't fire?? I noticed after bending them back a bit I get a pop or two similiar to a backfire. So I must not be getting enough fuel to fire it up?!?!?!??

  • Anonymous Nov 22, 2009

    So after replacing the fuel lines, same thing. Nothing changes (but the fuel lines needed replaced anyways). Any more suggestions I'm out....

    So.... it's been a a while. So today got a compression check, 0 compression all four cylinders. Took the valve cover off, removed all 16 rockers, closing the valves (right?) and still 0 compression? What it the world is going on??? WHY? WHAT?

Make sure you check timing and the belt. if it spun don't risk putting it back on. Hope you got a new key. TIMING is important so you don't stick a valve through the top of your piston

How to torque crankshaft pulley centre bolt on kia sportage

Usually with a heavy duty impact wrench (rattle gun). Put some thread-lock compound on the bolt also, as that is standard practice.

There may be at the transmission end some means of stopping the crank from turning, and then you could use a torque wrench.

How to replace Crank Seal , Honda Accord 95, F22B2 engine

this is covered in the FSM. 95 accord.
did you google this?
http://www.honda-acura.net/forums/accord/137349-1993-f22-crank-cam-balance-shaft-seal-hell.html

are you sure its only the crank seal,????
gravity lies. as does windage effects.
is this an A/T or M/T car, the latter makes the bolt come off easy
(5th gear + brakes) the slush pump tranny NOT.
so if you read the FSM it states." it shows photo of tire off and pulley bolt view and how the body ends just above that bolt, (see it?)
  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belts.
  3. If necessary, secure the crankshaft with a flywheel holding tool.
For some engines, a special pulley holder tool is available to secure the pulley while removing and installing the bolt (refer to the illustration)."
4 Remove the crankshaft pulley bolt. This bolt can be difficult to remove. Spray the bolt with penetrating oil and allow it to soak overnight. Book forgets to see CCW direction on bolt (RHT)
the bolt will take about 200fl/lbs of reverse torque to get off.
5 Carefully remove the pulley from the crankshaft. Do not pry it off.
6:
Remove the key from the crankshaft sprocket. Be sure not to lose it.
7 -If necessary, remove the tool holding the crankshaft.

remove seal with seal puller or screw trick ,etc.
do not damage the seal base collar of the housing. DO NOT.

is this your first engine seal work>?
or done many , just need help with one honda.?
if doing all work on a honda, did you ever consider a real FSM?
why not get one, and read it, and all the steps and warnings.
worst case.
if you work engines, you know as you go , you see
Omg, it not the crank it the cam leaking, or just a bad valve cover.
fate happens, distributor seal leak too.

with all FWD, doing a crank seal can be easy or hard.
no access panels in finder
or on some cars, 7ton pressed on pulley, (Dodge neons/ yuk)

bolt spec:
1994-95 Accord and Prelude-181 ft. lbs. (245 Nm)

if the 90,000 mile timing belt is ignored, you will bend the head valves over, or worse... so...... all this , is a consideration.

Cant loosen the bolt on the harminic balancer pulley

no engine stated, so any help will be wrong, !!!!!!
V6? we cant open hood and look, so we are blind as bats. here.

bad input nets bad output , just like a computer.

i dont think its LHT. left hand treads.
its either rusty,
or last guy used red loctite and needs 300F heat to get IT, soft.
or your not trying up to 150fl-lbs of reverse torque.
my damper is at 100/ft/lbs
and will take way more to break free (no locktite)
my guess 2 is this is a slush pump car, a A/T tranny?
and as such , you cant lock the M/t in 5th gear?
sure, and the FSM shows what to do , to get it off for A/Ts
some engines, have special tool.
and or a pulley locking device. (home made works, made many)
some guys just use impact gun and strip the treads out of the crank
and the new FSMs all say, (DONT DO THAT, exactly)
in a shop the dork that does that , just calls you and say, hey buddy
your crankshaft is wrecked, (dont let them touch your engine)

btw l, read the fsm.
and all words for the UNSAID actions you are taking.
here is one , just to scare you.
quotes.
Reprogram the crankshaft position (CKP) pattern. Run the engine until the operating temperature reaches 176 degree. With the engine stopped clear the CKP pattern. Turn the ignition switch OFF. Turn the ignition switch ON and wait thirty seconds.
Check PULSAR F/B LEARN in the data list with the HDS. If not complete repeat the procedure. If complete, road test the vehicle on a level surface. Decelerate the engine speed of 5000 rpm to 3000 rpm. If equipped with automatic transaxle use two Drive positions. If equipped with manual transaxle use first gear.
see, may be the stuck bolt is a blessing,


here i will quote the pulley page for the 3.0L
just to show what a pain A/T cars are. (unsaid tranny )

  1. Raise and safely support the vehicle.
  2. Remove the right front wheel.
  3. Remove the splash shield.
  4. Remove the drive belt.
  5. Hold the pulley with the holder handle (A) and holder attachment (B).
  6. Remove the bolt with a heavy duty 19 mm socket (C) and breaker bar, then remove the crankshaft pulley.
7- clean the crankshaft pulleys (A), crankshaft (B), bolt (C), and washer (D). Lubricate with new engine oil as shown.
Install the crankshaft pulley, and tighten the bolt, as follows. Do not use an impact wrench.
  • Hold the pulley with the holder handle (A) and holder attachment (B), then tighten the bolt to 47 ft. lbs. (64 Nm) with a torque wrench and 19 mm socket (C)
  • Mark (D) the bolt head and crankshaft pulley as shown, then tighten the bolt an additional 60 ? (The mark on the bolt head should line up with the mark on the crankshaft pulley)

  1. Install the drive belt.
  2. Install the splash shield.
  3. Install the right front wheel.

note carefully this bolt is not set to a final torque,
it uses base plus angle.
id use a new bolt. (im savvy and hate buying new crank shafts)

1996 Jeep Cherokee Sport - 6 Cyl /4.0 Liter - Crankshaft dampener fell off. Proceedure for reinstall?

You will have to buy a new pulley to crankshaft bolt and washer. Or did you find that as well when you picked up the damper? Probably fell off a long time earlier. Buy a used one from salvage, or get one from a Jeep dealer.
The damper should only go on one way. Or there may be a missing woodruff key. It would fit into a slot on the crankshaft, holding the pulley in a set position. If the woodruff key is missing, you will have to find one of them as well.
Working from underneath, remove the "belly pan" mounted below the front of the engine. Book says you MAY need to remove cooling fans and radiator for access-but that is for removing the old pulley with a pulling tool. You may be able to get it all back together without pulling the fans or radiator off. Put a little clean oil on the crankshaft, align the key slot of damper with crank key and tap the pulley on with a soft faced mallet or appropriate tool. Get the pulley on, tighten down the bolt tight as you can get it, then belts back on. Then go to a shop and have someone put an impact tool onto the bolt to torque it down to specs-80 FT-lbs.
