So. I had the opportunity to replace the power steering pump on my IS200 that's done 150,000 miles with a newer pump that's only done about 70. Being a freebie I didn't pass it up. Anyways, after fitting the newer pump and putting the belt on, after tensioning it right (and before anyone says its not too tight, it's actually on the loose side), you can visibly see that the power steering pump pulley isn't lining up straight with the water pump pulley and the belt is slightly skee-wiff.
The bracket it mounts to is tight to the block. I've found, when I tighten the bottom bolt of the pump, it causes it to 'pull' inward and goes out of line. Any help would be massively appreciated.
