It may be necessary to hand rotate drive shaft coupling to attain proper positioning
of coupling insert lugs. This is to ensure easy engagement of fuel pump drive
coupling lugs into test stand coupling insert.
Place test stand coupling insert into test stand drive shaft coupling so that one lug of insert is at
11 o'clock position and another lug at 1 o'clock position.
Allow 0.0625 in. (1.5875 mm) clearance between drive coupling on fuel pump
assembly and coupling insert on test stand.
Loosen clamp bar and slide fuel pump assembly, test stand adapter ring, and test stand adapter
bracket on mounting rails until fuel pump assembly coupling engages with test stand coupling
insert. Check for proper clearance.
Tighten clamp bar when fuel pump assembly is properly engaged.
