INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts
• Measure clearance with feeler gauge.
• Clearance between outer rotor and oil pump body (position 1).
Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)
• Tip clearance between inner rotor and outer rotor (position 2).
Standard : Below 0.180 mm (0.0071 in)
• Measure clearance with feeler gauge and straightedge.
• Side clearance between inner rotor and oil pump body (position 3).
Standard : 0.030 - 0.070 mm (0.0012 - 0.0028 in)
• Side clearance between outer rotor and oil pump body (position 4).
Standard : 0.050 - 0.110 mm (0.0020 - 0.0043 in)
• Calculate the clearance between inner rotor and oil pump body as follows.
1. Measure the outer diameter of protruded portion of inner rotor (position A).
2. Measure the inner diameter of oil pump body with inside micrometer (position B).
(clearance 5) = (inner diameter of oil pump body B) – (outer diameter of inner rotor A)
Standard : 0.045 - 0.091 mm (0.0018 - 0.0036 in)

Regulator Valve
1. Visually inspect components for wear and damage. Mysql.
2. Check oil pressure regulator valve sliding surface and valve spring.
3. Coat regulator valve with engine oil. Check that it falls smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump body.

Ultima Evo Oil Pump Instructions
(Clearance 6) = D (Valve hole diameter) – E (Outer diameter of valve)
Standard : 0.040 - 0.097 mm (0.0016 - 0.0038 in)
If it exceeds the standard, replace the oil pump body.
CAUTION: Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own weight.
Assembly
Assembly is in the reverse order of disassembly.
• Assemble the inner rotor and outer rotor with the punched marks on the oil pump cover side.
CAUTION: Before assembly apply new engine oil to the parts as specified.

Ultima makes a High Output Oil Pump that should be comparable to the S&S for about 50% less. I can get the Ultima Pump for about $180 and the S&S will run me about $350. I don't see any reason for the extra price on oil pump (other than S&S is really proud of theirs) its about as basic as it gets nothing special
Anyways, asking if anyone has installed one and also which one is the right one?
I noticed they have two for Big Twins one is for 92 and Later Big Twins and the other is for 1984-1991.
Part # 98-518 is for 84-91
Part # 98-517 is for 92+
I am guessing the difference is the oil holes in the case and I would suspect the 117 needs the (98-517) 92 and later pump style?

I know John Sach's uses Ultima Motors so I imagine he has some experience with the Pumps, maybe we'll get him to chime in with his experience and confirm the correct model.
