Torque spec on 280 helmet/steering fork shoulder screws?-gctid393693

[Guest]

Hello all,

Basically as the title says....I can't find a torque specification for these screws/nuts. I had one come loose and fall out last weekend. The other screw had lost the nut and washer but was still in place. Long story short, I had no steering and had a heck of a time getting back to the dock. I'd like to make sure these nuts DON'T come off again.

If i'm reading the schematics right, the washer is placed between the helmet and fork correct? I think when I assembled it the last time, I put the washer with the nut. I really don't recall for certain tho.

I have the new shoulder screws installed with the washer between the helmet and fork, the nut being on the backside of the helmet. I have them cranked down snug but I really want to make sure these don't come out again. Having NO steering is NOT fun.

Is there a torque number for these?

Is loctite ok to use?

Look in your OEM service manual for the torque value.

The shoulder screws are tightened first, then the jam nuts are tightened against the helmet while still holding tension on the shoulder screw.

If you want to, you can use Loc-Tite on the shoulder screw threads.

Heat the helmet prior to removing them in the future.

NOTE: the threads in the helmet are NOT inserts as are most other Volvo Penta female threads......., so take a very close look at the condition of them.

Thank you Rick...

The threads in the helmet are questionable. I can tighten the shoulder screws only so much before they spin in the helmet threads. The shoulder screws do grab the threads but if I crank them down, they slip.

Am I looking at a new helmet?

Yes, that or thread inserts!

Most machine shops will be set up to tap and install thread inserts or a Heli-Coil.

These will require a high nickel content.... SS.

Thanks again....

I'll call around to some machine shops and see what I can find out. I like the idea of the inserts, if for some reason they stripped out in the future I can just replace the insert.

I imagine a new helmet would cost a pretty penny.....

• You won't actually loose the insert threads. What will happen, is that the aluminum will strip out.
• Call Brad at Fairview Marine in Oregon, https://"http://motors.shop.ebay.com...look on e-Bay.
  
  Many sellers will call these out as though they fit the 270, 275, 280.
  
  The 275/280 does not interchange with the 270, of which is a single pin. The 270 will bolt up, but your double bolt pin won't work in it.

What's a fair price for a helmet... I may have one for sale.

That would be awesome Gilligan! I haven't looked around at prices yet. Let me know what you want for yours... its off a 280 with the double bolt pin?

A machine shop would likely charge more to tap and install thread inserts. I may just buy a new(used) helmet. Lemme know what you want for yours Gilligan.

You can't beat 50 with Free shipping. I'd grab it if I were you.
