93 Toro 416H 0 #1 Posted 5 hours ago Hi everyone, My Dad & I were Wheel Horse dealers for many years. My Dad passed away and I am since retired. I have a 1993 Wheel Horse/Toro model 416H with the Onan engine. I am in need of parts for my tractor. They are as follows: # 116470 Muffler # 114214/57-9210 Exhaust Gaskets (2) # 71-5980 Intake Manifold Gaskets (2) # 57-8280 Valve Cover Gaskets (2) I have a loud clicking noise in my engine that has over 1000 hours on it. Not sure if it's a loose baffle in the muffler or a valve that needs adjustment. Any help you can be in locating these parts would be greatly appreciated. What is the correct valve lash setting on that engine? Thank you, John Pfennig 5179 Mapleton Rd Lockport, NY 14094 jhpennig@yahoo.com 716-530618 jhpfennig@gmail.com Share this post Link to post Share on other sites
lynnmor 8,967 #2 Posted 1 hour ago Download the Onan Service Manual for information. I don't know if your part numbers are correct. You might find a muffler on eBay. Do a compression test first thing to see if you have bigger problems. I doubt that valve adjustment will cure the noise. Visit our vendors section to ask about parts.

ri702bill 12,689 #3 Posted 1 hour ago Welcome! Do the compression test next. Onan's are infamous for valve seats loosening up their press fit in the block after 1100 hours or so..... Share this post Link to post Share on other sites
