Howdy members! First, you all have been great! Thanks!

 

Does anyone know the size of the woodruff key used on the crankshaft to align the timing sprocket and the pulley/harmonic balancer?

 

The vehicle is a 95 Legacy with the 2.2 engine.

 

BTW, the vehicle has 254,000 plus miles on it and other than routine maintenance it's been great for my son. He hasn't been so kind to it, three known crunches but none major. He has put the last 75,000 or so on it in the past 4 years so it's past due for the timing belt and related items.

 

Thanks for the input!

Called the crankshaft the camshaft in the title

I too need to know the answer to this, but it seems that the answer to this question is one kept a secret by the wizards of Subaru. I can not believe how difficult it has been to get a straightforward answer.

It’s been the same part for like a quarter of a century, just buy it from Subaru

 

1. call subaru, online subaru parts places, opposed forces for part numbers

2. If the timing sprocket portion is fine and holding then there’s no need to replace it. It’s entirely pointless and unnecessary for the crank pulley - just crank it down tight and they never come off. I’ve “fixed a bunch” which just means install the pulley and bolt and you’re done. Easy.

3/16" probably

 

Take the crank sprocket to an auto parts store and match it up.
