RJR49 121 #1 Posted November 26, 2018 (edited) The expansion pin on my steering shaft broke yesterday. The hole in the shaft is 13/64 (.203) but the pins at the hardware store are .187 or .228 (maybe 15/64) as measured with my vernier. I used the .187 and it fit very nice but I fear that it won't last very long. Are 13/64ths available, or did Wheel Horse make up their own. If I have trouble with it breaking I'm thinking that I might open up the hole to fit a .228. Has anyone tried that? In advance... thanks for the help BTW it's a C-160 Edited November 26, 2018 by RJR49 added model Share this post Link to post Share on other sites
Razorback 1,032 #2 Posted November 26, 2018 I think I would open it up for the larger pin. I lean towards overkill if there's an option! Share this post Link to post Share on other sites
pacer 3,159 #3 Posted November 26, 2018 I seem to recall that roll pins are designed to go into a slightly smaller hole, compressing it as it goes in. Hit up Google and find a chart for the pins - I've got one , the chart, --- somewhere? Share this post Link to post Share on other sites

RJR49 121 #6 Posted November 26, 2018 BTW there is a video on Youtube using a Vice grip to compress the pin. Unfortunately you can't compress them .025. I also checked the industrial suppliers. They don't offer any more sizes than the hardware store Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,491 #7 Posted November 26, 2018 Pins are usually sized by the hole size they are designed for. Split and spiral pins are a bit larger. Cotter pins and clevis pins are a bit smaller. Is there a chance the hole has a layer of corrosion in it? The bottom hook on the snowthrowers for the lift tube take a 3/16" cotter pin but most holes are much smaller because of a layer of rust. Garry Share this post Link to post Share on other sites
RJR49 121 #8 Posted December 2, 2018 I reamed it with a drill bit. More as a means of determing the size than cleaning but the next size wasn't close Share this post Link to post Share on other sites
