ri702bill 9,511 #1 Posted February 20, 2022 Bill here - has anyone found a way to permanently repair the fragile area that holds the steel clip in nut on a 2-piece 1960's Tractor?? I thought about bead blasting that area and using JB Weld to anchor either a nut plate or store-bought steel nut insert. I have 2 tanks to repair - one for the 502 and a spare for the 854. Any thoughts? Share this post Link to post Share on other sites
Poppa Phill 61 #2 Posted February 20, 2022 when it comes to missing materials, I have found that using hardware cloth and fiberglass resin makes a suitable permanent repair. Ive used flush mount rivets to fasten the hardware cloth to the objective, roughly form it making it larger than needed. after enough glass work trim and finish it off. your surface might work brazing it, but hard to tell from the photos. just my 2 cents worth.

What I plan on doing is sandblast the area clean and weld it completely solid. Then I can drill and tap the area. Like the factory did with the 701 tank. To weld it I plan on using these rods. https://www.harborfreight.com/8-piece-low-temperature-aluminum-welding-rods-44810.html Can be done with a common propane torch. I've used these rods in the past with good results. Edited February 20, 2022 by Achto 1 2 1 Share this post Link to post Share on other sites

stevasaurus 23,296 #5 Posted February 20, 2022 My 702 is not near as bad as what is shown in these pictures. I was able to use helo-coils in mine. Has worked for 12 -15 years now. I like what Achto is doing though for what he has. 1 Share this post Link to post Share on other sites

ri702bill 9,511 #7 Posted February 20, 2022 @Achto I considered that but wanted to eliminate the potential to tap drill too far and into the tank. My main concern was if there was a void in the welded material, and oops, compromising the wall of the tank. Then starts the cussin'😢. 1 Share this post Link to post Share on other sites
Pullstart 67,015 #8 Posted February 20, 2022 Welding those tanks… isn’t like welding other aluminums. PC-7 is an amazing machinable filler epoxy. You can also embed a greased bolt into the epoxy and simply back it out when needed. Usually too long of a bolt is to what tears those tanks out. 3 Share this post Link to post Share on other sites

One of these can eliminate that risk. https://www.lowes.com/pd/Kobalt-7-Piece-Depth-Stop/50041538?cm_mmc=shp-_-c-_-prd-_-tol-_-ggl-_-SS_TOL_215_Power-Tool-Accessories-_-50041538-_-local-_-0-_-0&gclid=CjwKCAiA6seQBhAfEiwAvPqu14yYT2ZZhkE5YXdQy_eDu8wYNULCs9G95PGt2rniqNtLNBrTGr0d7hoCgCkQAvD_BwE&gclsrc=aw.ds Share this post Link to post Share on other sites
Kenneth R Cluley 592 #10 Posted February 20, 2022 Repaired my tank on 653 with JB Weld and captive nut. Used a flange type nut. Turned out nice. 1 4 Share this post Link to post Share on other sites

I'm guessing you embedded the flange toward the tank, deeper into the JB Weld? Share this post Link to post Share on other sites
Kenneth R Cluley 592 #12 Posted February 20, 2022 Like others I thought about welding but some on here who have tried welding these tanks warned against that. Share this post Link to post Share on other sites
Kenneth R Cluley 592 #13 Posted February 20, 2022 Correct, put in so outer part of nut just below surface with flange in towards tank and filled in area with epoxy. Used greased bolt as someone said earlier to maintain orientation and placement. 1 1 Share this post Link to post Share on other sites
ri702bill 9,511 #14 Posted February 21, 2022 I will do the same - plan to use Petroleum Jelly, I'll save @peter lena's favorite green grease for other uses. Thanks all, Bill 1 Share this post Link to post Share on other sites
