About 1983 3.0l V6 - Twice now the key hoilding

About 1983 3.0l V6 - Twice now the keyway holding the pulley on crankshaft has broken, causing the pulley to spin on the crankshaft tip damaging the crankshaft. I am in the process of repairing again. Any ideas or solutions to prevent this happening again and why did it happen in the first place?

Installation
1.Install No. 2 idler pulley (if removed). Install and tighten bolt to specification. See TORQUE SPECIFICATIONS . Ensure idler pulley is clean and rotates smoothly. 2.Install No. 1 idler pulley and tension spring (if removed). Pry No. 1 idler pulley away from timing belt area as far as possible. Temporarily tighten No. 1 idler pulley bolt. Ensure idler pulley is clean and rotates smoothly. 3.Using crankshaft pulley bolt, rotate crankshaft so timing mark on crankshaft sprocket aligns with timing mark on oil pump housing. See. This will position keyway in crankshaft sprocket at 12 o'clock position.

CAUTION:If reusing timing belt, ensure reference marks on timing belt align with reference marks placed on crankshaft and camshaft sprockets. Ensure timing belt is installed in original direction of rotation.
4.Ensure all sprockets and idler pulleys are clean. Install timing belt on crankshaft sprocket, oil pump sprocket, No. 1 idler pulley, and then No. 2 idler pulley in sequence. 5.Install timing belt guide with cupped side away from crankshaft sprocket and flat side toward timing belt. Install No. 1 timing belt cover and new gasket. 6.Align crankshaft pulley key groove with key in crankshaft. Install crankshaft pulley. Install and tighten crankshaft pulley bolt to specification. 7.Rotate crankshaft clockwise so cylinder No. 1 is at TDC on compression stroke. Ensure timing mark on crankshaft pulley aligns with "0" mark on No. 1 timing belt cover. If reusing timing belt, ensure reference mark on timing belt aligns with upper edge of No. 1 timing belt cover. 8.Rotate camshaft, and align hole in camshaft sprocket with alignment mark on camshaft bearing cap. See Fig. 2 . Install timing belt on camshaft sprocket. If reusing timing belt, ensure reference mark on timing belt aligns with the reference mark on camshaft sprocket. Ensure tension exists on timing belt between the crankshaft and camshaft sprockets.
CAUTION:DO NOT rotate crankshaft counterclockwise, as viewed from timing belt end of engine.
9.Loosen No. 1 idler pulley bolt 1/2 turn. Rotate crankshaft pulley 2 full revolutions clockwise from TDC to TDC. 10.Ensure timing mark on crankshaft pulley aligns with "0" mark on No. 1 timing belt cover, and hole in camshaft sprocket aligns with alignment mark on camshaft bearing cap. See Fig. 2 . If timing marks are not aligned, remove timing belt and reinstall. 11.Rotate crankshaft clockwise 1 and 7/8 revolutions and align crankshaft pulley "0" mark with 45-degree Before Top Dead Center (BTDC) mark on No. 1 timing belt cover. See Fig. 5 . 12.Tighten No. 1 idler pulley bolt to specification. See TORQUE SPECIFICATIONS . Install No. 2 timing belt cover and gaskets. Install and tighten spark plugs to specification. 13.To install remaining components, reverse removal procedure. Install all bolts/nuts on right (timing belt side) engine mount before tightening to specification. 14.On Camry, when installing control rod and bracket on strut tower and right (timing belt side engine mount, tighten bolts to specification in sequence.

The serpentine belt pulley on the crankshaft dampener has separated from the dampener and is moving forward, throwing the belt off. It is about 1/2 inch forward, and a black rubberish gasket is working...


yes, you need a new dampener. You will need special tool--a puller. the procedure from autozone.com is as follows:
  1. Remove the drive belt.
  2. Raise and safely support the vehicle.
  3. Remove the right front tire assembly.
  4. Locate and remove the right splash shield.
  5. Remove the crankshaft balancer bolt and washer. (my note: you may need to remove the starter and lock the flexplate starter gear with a screwdriver to hold the engine while loosening the damper bolt)
  6. Remove the crankshaft balancer using a three-leg puller such as J 24420-B, or equivalent.

Fig. Crankshaft balancer removal-3.1L engine


To install:

  1. Clean all parts well. Apply a thin coat of sealer GM #12345739, or equivalent, to the keyway of the balancer. This is to help prevent oil from wicking along the keyway and causing a leak.
  2. Install the crankshaft balancer using tool J 29113 Crankshaft Balancer Installer or equivalent, to draw the balancer onto the crankshaft. Do not hammer on the balancer. (my note: I have never needed this tool. I slip the balancer on and draw it in with the bolt)
  3. Install the crankshaft bolt and washer and torque to 76-80 ft. lbs. (103-108 Nm).
  4. Install the remainder of the components in the reverse order of removal.

Crankshaft Woodruff Key Removal


You are correct, this key does drive both. While I have never tried to remove the keway with out both pulley and lower sprocket you may be able to (my gut says no but anything is worth trying once) I'd position the keyway at the 12 o'clock postion and with a good pair of needle nose pliers see if the key will roll out as you pull up and away with it. If it will not you'll of course have to remove the front of the engine and pull the timing belt, if over 60K miles on belt go ahead and replace with new.

I hope this may have assited and good luck!

I have 2.8 td rodeo the pulley keyway has wallowed out as well as the keyway on the crankshaft. IS replacing the crankshaft the only solution. As the keyway is only worn and front where pulley has been...


You could take the old crank out and send it to a machine shop with the pulley and have it repairedwhich will probably be less than the cost of a new crank but will still need all the work and new parts that a new crank entails.
You could also take an afternoon and go to work with a small file and square up the keyways. You can get new keystock in an assortment of sizes at the auto parts store. If you do this make sure you have a snug fit with the new key or it will beat itself out again. Patience is the key here.
You could also just replace the engine, hopefully with one that has lower mileage. Hope this helps.

The key for the central pulley on my 1994 Legacy has broken. Can this be fixed without removing the engine? If so, can you tell me how?


i presume that you mean the crankshaft keyway, really when this damages, the tolerance is wrecked and the crank needs to be repaired and remachined, or failure will happen really fast...

Camshaft pulley is completely off


The one item determining if this can be repaired is the condition of the keyway on the crankshaft and pulley. (the slot where the locating key goes) If the slot is severely damaged on either the crank or pulley, you will need to replace the damaged item. (if it's the crankshaft, its a really big job.) If it's not terrible, you can file it back to shape with a small flat file and get a new woodruff key. Chances are the majority of the damage is at the pulley. That should be changed. Otherwise, putting it back on is just a matter of sliding it on and tightening it up. (if you do this with hand tools, bring it to a shop afterwards and ask them to put an air gun on there to finish tightening.) You can usually get another pulley from any scrapyard far cheaper than a new one from dealer.
