thebunns 11 Posted June 28, 2019 Share Posted June 28, 2019 I pull the intake manifold off my TD-14 about once a year to free up the butterfly shafts. I can't remove the valves because the screws are set & I'll strip them if I put any more torque on them. I shoot penetrating oil on all places that the shafts exit the manifold & work them until they are reasonably free. I don't have any luck lubricating them with the manifold installed on the motor. Any thoughts or ideas on a fix would be appreciated. Vic Quote Link to post Share on other sites
crawlernut 14 Posted June 29, 2019 Share Posted June 29, 2019 Vic, On my 14 A, the butterfly valves were stuck tight. I heated the small screws with a small oxy torch and got them out. I cleaned the shafts up and ran a bore brush thru the shaft housing. Reassembled with some Neversieze and its been working since. Some times i need to reach behind the manifold and pull up on the V flipper till it clicks, but then its good to go. I don't start and use the tractors often enough to keep things free and loose, so a little TLC at start up is sometime needed. Jim. Quote Link to post Share on other sites
thebunns 11 Posted June 29, 2019 Author Share Posted June 29, 2019 I thought of heating the screws. I'll try it. I would like to free up the valves like my -14A. I pull the V flipper up every time I switch to gas. Both tractors are used only in winter to plow snow but I start them, and every other engine I have once a month all year so that helps a bit. By the way, is the V flipper keyed on the shaft or do I have to figure out where to put it when reassembling it so the valves will operate correctly? Vic Quote Link to post Share on other sites
crawlernut 14 Posted June 30, 2019 Share Posted June 30, 2019 Vic, It is held on with a notched bolt from the bottom of the flipper casting. One position only. Jim. Quote Link to post Share on other sites
thebunns 11 Posted June 30, 2019 Author Share Posted June 30, 2019 Thanks---sounds like one more bolt to get loose. Vic Quote Link to post Share on other sites
