1989 Force 125 water pump torque values

[fishbait2]

I have a Quicksilver FK 1202-1 Water pump kit. The plastic pump cap has printed 40 to 50 In lbs for the 1/4 nuts and only 15 in lbs for the 3/8 or 10 size smaller nut. My Shop book states 70 in lbs for the 1/4 nut size and nothing for the 3/8 or 10 size nut,( I have found a 120 Force video that states 40 in lbs for the 3/8 or 10 size smaller nut) So I need to know why the difference? At this time I have it torqued at what the pump cap states. But worried it will not last or is correct. Anyone know the answer?

Stick with the torque-values mentioned on the cap

I agree with The Force power.....they probably reduced the torque value because the housing is plastic.....the aluminum housings had 4 bolts and used the 70 in/lb torque. They put the torque values on the plastic pump housing to make sure you don't over torque it.

70 inch pounds is like 6/7 pounds and not very tight.
You worried about them backing out?? A touch of sillycone or lock tite.
