Some progress today. Moved engine from (freezing) garage to basement. Projected belt/ancillary/tensioner layout.
The compressor on the floor is a Volvo SD-709, from a old 760 V6. I can bolt that up to the block for gauging tensioner placement and belt length.
Ordered the SD4514 serpentine clutch assembly.
(Thought) I inverted the WP pulley here...
Went through my Volvo parts, after spending hours looking at any number of crank pulley/damper permutations for something close.
The '99-04 V70 power steering pump has a metal (approx) 5" OD pulley. The slight increase in OD should help overdrive the water pump and alternator for low rpm increase in circulation & voltage output..
So, I'm going to have the inset machined off, and the stock pulley machined down so that the serpentine pulley will be an interference fit. Pulley has to be offset about 1/8" back over the inner lip to allow belt to sit correctly. I'll make final adjustments to the offset before welding/pinning the pulley to the hub. Much less machine work than reducing the stock pulley to a hub & drilling/tapping to fit an Audi/VW style damper.
Alternator with serp pulley
Idler stuff. I have at least three different OD tensioner pulleys.
possible tensioner setup
belt alignment (WP Pulley is inverted in these two pics)
gauging water pump pulley offset needed
EDIT: Not sure there is enough clearance for a 1/2" deeper WP pulley. Edit2: Not a problem, see later posts
Stock compressor pulley - may need to offset compressor 1/4-1/2" outward
