I noticed you bought Sonnax 34006-SPB......This product hasn't been on the market for 6 months.
I recommended 34006-SP that works with the TH350 Pump Bearing when installed backwards. It's $25 dollars cheaper as the CK kit comes with the output rollerization parts.
34006-SPB comes with a larger diameter bearing & shims that go over the lip of the bushing.
Because you installed the bushing backwards.....You CANNOT use the Sonnax supplied bearing & shims!!!!!!
If I would have known you ordered the "B" version......I would have amended my instructions. If you mentioned ordering the "B" version.....I missed it & apologize for the oversight.
