Yes, and can be a real PITA to adjust. At least in this install looks like there is very good access. Ive mostly dealt w them on FP & Lagoon cats where there is a bulkhead a few inches in front of the engine! [emoji849]

Also means you need 2 types of belts in spares.

To say nothing of changing the impeller but yes, this one does appear to have good access.

No pump and no hoses unused hoses in the photo

I found it easier to just remove the whole pump to change out the impeller. Otherwise you're working from the back side and can't see what you're doing, and hard to get the screwdriver in there to turn the cover screws. Actually ends up being quicker that way too.
