Q: Page 37

I don't see how this is gonna work with both being seals. I think 33 on the inside of the pump should be a seal. And what they got listed as a seal on the outside should be a bearing. （Notice the yellow circle in this pic）
They got it as being 33. there is a lot of friction intention on this gear for that to be a seal on the outside of the water pump. See the line going to the engine. This plate attaches there. They're showing (2) 33. One has to be a seal on the inside of the pump. The other, however, should be a bearing on the outside of the pump to support the gear.
