Posts: 129 Austin, TX | I am unable to ease the outhaul on my N20 (without sticking a screwdriver in the slot and pushing). Has anyone serviced an N20 boom with internal outhaul?
I'm thinking that I have to take the end caps off to service the outhaul car and I've drilled out the rivets, but the caps WILL NOT BUDGE. Any hints would be much appreciated.
Thanks! Bo

Posts: 3,224 Roanoke Island ,N.C. | The stainless rivets that hold the end cap on have most likely corroded(Galvanic Reaction) with the aluminum making the cap hard to get off. I had to use a large screwdriver and a hammer with large amounts of penetrating oil to get mine loose a few years back.Use the screwdriver like a dull chisel to tap around the end cap. Just be careful you don't break the casting. Todd

Posts: 129 Austin, TX | Thanks... I've gotten the idea...
I've washed it, but not with a pressure washer... If pressure washer works, I'll put in Al rivets.
Next try oil, then heat...

On-line ordering at <a href="http://store.hamiltonmarine.com/browse.cfm/4,33364.htm " target="_blank">http://store.hamiltonmarine.com/browse.cfm/4,33364.htm </a> Or we could ask Rick if it will be offered on the Catsailor store - I need a new tube myself.

Why dont they use alum rivets? I just removed stainless rivets from my alum upper rudder castings.... seems like a no-brainer to me? On items that see cyclical loading (like a rudder arm does), aluminum rivets will loosen pretty quickly. Stainless or monel rivets will hold longer before you need to tighten the joint. Of all the work I've done on I20s, I've never had to get into the outhaul. I HAVE had them stick and my F18 got quite bad after a capsize left the boom in some sand (long story). To free it up, I usually put the boom in the (freshwater) lake, and work the outhaul repeatedly underwater. It seems to have fixed every sticky one I've had to deal with. As far as getting the endcap off, I would recommend the use of a body repair slide hammer. Drill a hole in the end of the cap (or a few) and work at it with the slide hammer. If that won't get it off, you should prepare to cut it out.

Thanks!

My other advice would be sure to clean everything off with a fine wire brush to get all the crud off and then clean & rinse w/soap & water. When reassembling I had coated everything with TEF-GEL http://www.tefgel.com/contain.php?param=tefgel_inforto keep this from happening again. Also consider using monel rivet with the reassembly. Oh!

Why not use aluminum rivets? - they're not carrying any load there and the like metals will be much less likely to corrode.

Good point, as I recall these rivets are more for holding the end cap in place and would note take too much load. When reassembling my boom I had to rubber mallet the end caps in. My suggestion for Monel came from something I had picked this up from a AP & I when I use to own a Piper. Almost as strong a stainless and won't cause corrosion like aluminum. | | |
