johnscag 7 #1 Posted September 25, 2012 Can anyone help me identify the engine in my wheel horse Raider 10, 1969 1-6041 Model. It developed what appears to be a bad valve tap. I will try and attach photos, but i did upload to my gallery. Thank you! Share this post Link to post Share on other sites
Rock farmer 41 #3 Posted September 25, 2012 It should be a kohler 10 horse. And it appears to be a kohler 10 horse. Joe Share this post Link to post Share on other sites

racinfool40 202 #5 Posted September 25, 2012 You have a 1969 Raider 10 with a 10 Hp Tecumsah..Model # for the tractor is 1-6041 and the engine is a HH 100 spec # 115095B...Take care of that engine and be careful of that solid state ignition..if it goes bad..Hold on they are pretty pricey if ya can find one!!!

sorekiwi 761 #6 Posted September 26, 2012 (edited) I agree with Mike on this one, that is a Tecumseh. The motor should be covered in this manual in the files section: Welcome to Red Square! EDIT: Changed link to the correct manual - Sorry! Edited September 26, 2012 by sorekiwi Share this post Link to post Share on other sites
Rock farmer 41 #7 Posted September 26, 2012 I stand corrected! Those guys would Know better than me. Valves tend to chatter connecting rods tend to rap. How did this happen? Joe Share this post Link to post Share on other sites
MarkPalmer 81 #8 Posted September 26, 2012 From the photos the top end of the engine looks pretty good. The tapping noise could just be from normal valvetrain wear, I don't think those Tecs have adjustable tappets like the bigger Kohlers do, rather you have to pull the valves and grind the faces, lap them to the seats then grind the stems to re-adjust the cold tappet clearances. Those HH's were a very good engine, and are generally worth some investment to repair/rebuild. -Mark- Share this post Link to post Share on other sites
Buckshot 1 15 #9 Posted September 26, 2012 :) Very nice looking tractor. I tend to agree, valve lash problem. Some of the early HH series had a soft cam and it could be a worn lobe. But you might want to check crankshaft end play :flags-waveusa: Share this post Link to post Share on other sites
johnscag 7 #10 Posted September 26, 2012 Gentleman, thank you for the great information! Upon review today i "think" i may have located the issue. I will attach a photo that shows a gap between the exhaust valve and the push rod from down off the cam? The right side, seems to never have a gap, but the left side seems to seperate just a bit, At this point i am over my head , sounds like i need to pull the engine and take to a machine shop and the will build up the exhaust cam to make up for the difference? Thanks a million! Share this post Link to post Share on other sites

Thanks a million! The exhaust valve should have a significantly greater cold tappet clearance than the intake valve- one that is easy to see. You'll need to look at the HH manual and get a set of feeler guages to measure the clearances, (With piston at top dead center on the compression stroke) but "typical" cold valve tappet clearances are .006-.008" for the intake valve, and .015-.019" for the exhaust valve. These clearances often have to be quite a ways out of spec before the valvetrain makes a lot of "unusual" noise. The valvetrain commonly does make some noticeable noise that is considered normal during operation, as it's a solid lifter design. -Mark- Share this post Link to post Share on other sites
