Rod cap alignment tool

[Captain75]

Hello!
I just got an OMC Rod cap alignment tool by mail. The tool is brand new, but it didn’t come with any user instructions. The manufacturer refers to a OMC shop manual. The manual I’ve got doesn’t include any such instructions.
Anyone who are in possession of these instructions? If so, could you take pictures of
these pages and post them on this board?

Install Rod Cap Alignment Fixture, P/N 396749, before tightening rod cap screws. Align the flat marked “SET” on the rod engagement stop with the arrow on the frame. Position stop at the center setting (one line showing). Rotate adjustment knob 180° to lock in position.

Secure restraining jaw “C” and forcing jaw “D” to frame.

IMPORTANT: Torquing the screws without Alignment Fixture, P/N 396749, or using an incorrect procedure could cause permanent damage to the connecting rod and crankshaft. To maintain accurate torque values, keep torque wrench extension length to a minimum.

Apply a light coat of outboard lubricant to the corners of the connecting rod and rod cap. Place frame on connecting rod using the following procedure:
• Position frame onto the connecting rod so the contact area of the jaw is centered on the side of the rod.
• Tighten forcing screw until jaws contact connecting rod.
• Slide frame down until adjustment stop contacts the rod cap. The groove lines on the jaws must be centered on the rod/crankpin diameter.

1. Adjustment stop 2. Groove line

IMPORTANT: Make sure that frame is squarely in position and that rod and cap are aligned.

Tighten the forcing screw to a torque of 14 to 16 in lbs. (1.6 to 1.8 N·m). Do not overtighten.

34461

Loosen both rod cap screws one-quarter turn.

Use Torquing Socket, P/N 331638, to tighten rod cap screws in three stages:
• Apply an initial torque of 40 to 60 in. lbs. (5 to 7 N·m) to both rod cap screws.
• Torque screws to 14 to 16 ft. lbs. (19 to 21.7 N·m).
• Apply a final torque of 30 to 32 ft. lbs. (41 to 43 N·m).

Loosen forcing screw and remove the frame.

IMPORTANT: Test at least three corners of the rod and cap joint with a pick. Joint must be smooth with no step.

Ssv170...
Do you by any chance have the pics too?

This part is a bit hard I think:

”Tighten the forcing screw to a torque of 14 to 16 in lbs. (1.6 to 1.8 N·m). Do not overtighten”

I can’t even find a torque tool that covers as low values as 1nm...
Someone have a trick up their sleve? Just snug the forcing screw?

Being a po Floda boy, I've never used this tool. Does this mean my chit's gonna blow up?

The more I think about this, the more strange it appears...
1.6-1.8; thats almost nothing!? You can almost accomplish that with your fingers!?
Can this really be right?

You need a dial style torque wrench for this. Do not use a click type. I will look in my manual and see if I can get something scanned.

There are 2 versions of the tool - early one had a built in clutch, later one just a 1/4” socket hole for small torque wrench as mentioned. As far as the torque value, I was taught by OMC Master Techs to just use gentle pressure with small 1/4” ratchet, been working perfect

The alignment tool the factory used was spring loaded to hold the cap strait.
