Tunable rudder screws rusted Printed From: CorrectCraftFan.com Category: General Correct Craft Discussion Forum Name: General Discussion Forum Discription: Anything Correct Craft URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=47950 Printed Date: March-06-2025 at 5:10pm Topic: Tunable rudder screws rusted Posted By: Wtrskior Subject: Tunable rudder screws rusted Date Posted: August-22-2019 at 5:16pm The rudder on my 01 SN had the tunable foil. I'd like to adjust but the screw heads are heavily rusted, to the point that it's barely possible to see that they were Philips heads. I assume the screws are also rusted in there. Any suggestions on how to remove the screws and replace?   Any chemical that will deoxidize the screws so I can loosen? I've tried PB blaster.   Wouldd prefer not to pull the rudder and take to a machine shop!! ------------- 2001 Ski Nautique CB w/ GT40 Replies: Posted By: DVskier Date Posted: August-22-2019 at 5:57pm Is it possible to get a grip on the head of the screws with vice grips? Of course they’ll need to be replaced with SS screws after removal.

You probably get the PB at HD too!! 8122pbrainard wrote: BTW, Here's a copy from a previous post: You too have fallen for the BS!!! 8122pbrainard wrote: You have fallen for the BS advertising hype with the PB! Go for the scientific facts and not what's written on a can. "as advertised on TV" is always a dead on indication that a product is C***. If I remember correctly, Billy Mays at one time was pushing the stuff! 8122pbrainard wrote: Here's the list of torque requirements copied from another thread: Penetrating oil ..... Average load None ...................... 516 pounds WD-40 ................... 238 pounds PB Blaster ............... 214 pounds Liquid Wrench ......... 127 pounds Kano Kroil .............. 106 pounds ATF-Acetone mix.......53 pounds I don't even consider WD40 to be a penetrating oil so that puts PB at the bottom for me. Kroil is a on line order only so when I was taking my 1927 Flexifour apart and trying to break the rusted pistons loose, I did pick up a can of PB. A week went by with no luck and then the Kroil came in. The next day after using some of the Kroil, all four pistons were loose. I ended up using the PB as a honing lubricant! Go for the 50-50 home brew. It works as many including myself have found out. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < Posted By: 67 ski nat Date Posted: August-22-2019 at 10:20pm I could not get visegrips on my heads, no space You need to create head on other end of bolt Split a nut on the short dimension Thread onto bolt, grap nut with vise grips, without ruining threads it will act as clamp too Pb blaster previously soaked and try to remove existing rusty nut Once the rusty nut is away from surface tap bolt out to allow visegrips on original head Took me 1 hour each And there always the double nut trick. For adults Posted By: 67 ski nat Date Posted: August-22-2019 at 10:33pm BTW. I’m gonna try some of the other recipes. Had no idea liquid wrench was better Posted By: Wtrskior Date Posted: August-22-2019 at 10:56pm Haha. Thanks Pete.   Im pretty sure I got the PB at Canadian Tire aka church. I also have a can of seafoam deep creep,about 2x the price so I use it sparingly but I'll mix up some home brew and give it a shot. ------------- 2001 Ski Nautique CB w/ GT40
