mrc 958 #1 Posted June 17, 2012 hi guys, i'm working on a 414-8 with the horizontal muffler. muffler is directly above pto. the pto trunnion has to be installed from the bottom going up. yet it just seems to me i always see them going in from the top down. is there a correct direction for installation??? thanks you. mike in mass..

sorekiwi 761 #2 Posted June 17, 2012 Off the top of my head, I dont remember which way it goes on my 520. But I do know that if you put it the wrong way around it binds up the linkage at some point in its travel. Share this post Link to post Share on other sites
varosd 1,185 #3 Posted June 17, 2012 on my 77 B-80 it's on the top. my 520 had it on the top but in previous thread and right there in the owners manual it is from the bottom. as long as it doesnt bind, stays engaged and it has free travel, not sure how critical it is.

Forest Road 594 #4 Posted June 17, 2012 All depends how hot the muffler is when I install mine. Dont think it matters much on my 300s or c160. Share this post Link to post Share on other sites
can whlvr 994 #5 Posted June 18, 2012 with the horizontal muffler you have to go up from bottom or it will hit the muffler Share this post Link to post Share on other sites
dbartlett1958 99 #6 Posted June 18, 2012 My 416-H has it going up from the bottom. As can whlvr says, it will hit the muffler otherwise. Share this post Link to post Share on other sites
dsholler 54 #7 Posted June 18, 2012 I have a 414-8 and have always installed it from the bottom. Mine came with two washers on it as well, to lower the rod even further. That setup has worked perfectly for me, although the thing still gets hot as blazes from the muffler... let it cool down before working on the PTO...
