Is there a separate woodruff key??for the Crankshaft gear??
Im doing the water pump & timing belt.& before I put it back together,,,is there a key?Is there a difference between the frnt & back washer?

Dear Blindboy,

Hope you're well. When re-assembling the crankshaft timing parts - rear washer, sprocket (gear), front washer, and crank pulley - it is critically important to ensure that the sprocket's "nub" (or protrusion) aligns with: (a) the notch in the front washer, and (b) the crank pulley's slot.

To ease this task, use white-out (or other light-colored paint) to mark on the crank pulley's face (the flat surface just below the rim) the crank pulley's slot location. Position the crank pulley onto the crankshaft, with the paint mark aligned with the "nub" on the crank sprocket. Once you've aligned the pulley and the "nub", do not turn the crank pulley: push it straight back along the crankshaft.

If the crank pulley is properly seated on the crank sprocket's "nub", you should not be able to turn the crank pulley without great effort. For, if the crank pulley is properly seated on the crank sprocket's "nub", moving the pulley requires moving the pistons and valves. If the crank pulley is not properly seated on the crank sprocket's "nub", the crank pulley can be turned with relative ease. If that occurs, slide the crank pulley towards the front end of the crankshaft, re-align the pulley with the "nub", and try again.

The "nub" protrudes only 1/16" from the front washer's surface, so it is easy to misalign the crank pulley, by, for example, turning the pulley slightly while pushing it along the crankshaft. When installing the crank pulley, be careful to push the crank pulley straight back towards the face of the engine!!

Even when the crankshaft bolt is fully torqued, a misalignment will allow the crankshaft to turn "independently" of the pully. That rotation will shear-off the crank sprocket's "nub". A replacement sprocket (#9135271) will cost about US$77 (MSRP) at a U.S. Volvo dealer.

Hope this helps.

Yours faithfully,

Spook

I had this similar experience after changing the timing belt - I didn't torque the crankshaft bolt to specs and it came loose- causing mis-timing -
had to take it all apart to sent the harmonic balancer on correctly- fortunate that the nib on the sprocket wasn't damaged=
the two washers you speak of are shaped with flared sides which keep the timing belt from contacting the metal edges, that could result in a torn belt possible. I don't think the washers are available as a solo part, so one would have to visit a scrap yard or a pick-n-pull to get them-
a good parts source in Calif. is "smithvolvoautoparts.com"-the web page has diagrams and part numbers of the parts as well as availability - customer service is good also.

The key is built into the gear.

The washers are different, the outer washer has a notch on the outer rim for timing the belt and a notch for the nub on the front of the crank gear that also locates the crankshaft pulley.

so does the rear washer,move freely??

No, it gets pinched behind the crank gear when the crank bolt is tightened.

thanks I should ve slowed down when I was taking it apart & tooks pics of all,,now that I located crank gears online,it doesnt look to different from those new pieces,,I have heard that JB weld can be used to fix crank pieces,,i may to try that cause its faster,
