jsp_333 273 #1 Posted January 12, 2022 Belt Guard Bolt to K91 engine I've tried a bunch of things too hold this bolt in place - lock washers loktite nothing seems to work I've just noticed there is supposed to be a spacer in between belt guard and engine but can't see how that would solve the issue. What am I missing? Share this post Link to post Share on other sites
jsp_333 273 #2 Posted January 12, 2022 Issue #2 Restoring Hood Openings to something approaching Original So the openings for gas tank cap and steering rod on my rj have been altered (cut) crudely. I'd like to get them back to a finished original look. I tried bondo and a papertowel core on the gas tank opening with unsatisfactory results. I'm sure someone on the site has come up against this in the past. If anyone can offer some help it would be appreciated. Cheers, John Share this post Link to post Share on other sites

stevasaurus 22,914 #4 Posted January 12, 2022 @jsp_333 Your restoration thread will work much better for you if you keep all of the issues in one thread. Everything will be in one place and easy to find. 2 Share this post Link to post Share on other sites
jsp_333 273 #5 Posted January 12, 2022 As you wish sir. Did 2 threads intentionally because I thought it would be more confusing as one. I defer to experience. Tomatoes tomattos. Welder, sadly no. 1 2 Share this post Link to post Share on other sites

Do you know any one that has a wire feed welder that could weld some patches in for you? Using Bondo will only result in it cracking and falling out. Bondo should only be used to fill imperfections not holes. If you can't get new metal welded in place, you could try using fiberglass to make your repairs. Not the absolute best option but it will provide the support needed for the job. Make sure that the metal around the hole has a deep mechanical scratch in it, 24 or 36 grit grinder wheel would work for this. Make sure that your patch extends out at least 2" all around the hole. Putting fiberglass on both sides of the sheet metal would be a good idea as well. 1 2 Share this post Link to post Share on other sites

The spacer would give the bolt some thing to tighten against. You could use a threaded rod and 3 nuts. Thread rod into the engine, Install 1st nut as a jamb nut to lock the rod tight into the engine. Thread nut #2 on to the rod adjust it to get your belt guard to sit the correct distance away from the engine. Put the belt guard on and use the 3rd nut to hold it in place. 2 2 Share this post Link to post Share on other sites

Putting fiberglass on both sides of the sheet metal would be a good idea as well. For the gas tank hole, see if you can find a large rubber grommet at your hardware store in all those little gray drawers to fit loosely on the filler neck and overlap the rough metal hole. Taking it to a welder is the best option, but Fiberglass is your next best option. If you have no glass experience get a kit from Home Depo or your hardware store. Watch some online videos. Practice on some hard cardboard or plywood similar shaped holes. my hint, sometimes its seems hard to get all the fibers to lay down. One you have the fibers well wetted with resin to the metal, lay a piece of non-stick plastic wrap across the wet fiberglass. Have a helper help you so your holding all 4 corners of the wrap to keep the wrinkles out as you lay it into the glass. Then you can use your hands to smooth it out. Do the bottom first with plastic wrap then heavy tape covering the hole from the top side. Use a very thin smooth piece of glass, especially on the top side, such as hoppy shop model airplane thin thickness. Let it dry, use a dremel to smooth anything not flush on the top side. Also scratch up the hard glass surface that the top side glass will adhere to. Repeat using the bottom glass like you did the tape. fiberglass sands hard. so again use a dremel or electric sander to work to a rough smooth shape. Use Body Putty to smooth scratches in the glass and blend to the surrounding metal. For the belt guard, assemble stacking on the bolt a flat washer, belt guard, flat washer, spacer, then screw into the block.

jsp_333 273 #9 Posted January 16, 2022 Been away a few days so I'm just getting to this. Thanks all. I'm going to start with the rubber grommet idea. So I get a factory edge. Or a spacer washer if I can find the right sized hole. Tinkered with the belt guard assembly today. I've got lock washer and nut on the end of the bolt closest to the block. Couldn't get the engine to fire so ... Share this post Link to post Share on other sites
