Cracked LH Camshaft Timing Pulley

[BANGUM]

Hey Guys!
The mechanic told me that my timing belt slipped on my 1MZ-FE 1995 Camry, so I decided to tackle the project myself. After I was able to get the timing belt covers off I found that the LH Camshaft Timing Pulley is Cracked and I also found a roller from the Camshaft bearing. My questions are: (1) is this common? (2) Is the car practical to fix? (3) if fixable, what are the part numbers for the Camshaft pulley and bearing and where should I buy the parts from? (4) Could there be engine damage? See picture for more info.

I highly doubt that pulley cracked under normal use, I'd say someone assembled the engine incorrectly, or damaged it doing a timing job at one time. Hit an auto wreckers for a replacement, cheap and there are plenty of 1MZ engines in most yards. The needle bearing (if that's what it is) I have no idea how that could have happened or where it's from, the camshaft bearing has smooth journals not roller bearing parts.

I hope that's not the index pin on the camshaft...

I was wondering that after thinking about it, but even if it is, the cam could still be fine, the pin might have just fallen out due to the broken cam gear. Strange problem for sure.

If the cam sprocket is cracked then it's most likely poor workmanship from the previous job.

As long as the surfaces aren't damaged, and if the locating pin and can still go back in then all should be well after getting a new sprocket. There is no needle bearing that I know of in that area.
