Live4outdoors 151 #1 Posted June 18, 2015 I have a 876 that loves to mark her territory all over my barn floor, I'm thinking I need to fix it but it runs and drives great and hydros always scare me, any suggestions, how hard is it to change gaskets in them? Any suggestions of where to get gaskets and what not to do? Thanks all in advance! Share this post Link to post Share on other sites

oldredrider 2,547 #4 Posted June 19, 2015 Usually just o ring replacement behind the nylon thingy. One of them is still available...substitution may he required for the other. Share this post Link to post Share on other sites

Live4outdoors 151 #6 Posted June 19, 2015 No unfortunately the whole underside is soaked, I'm sure it's at the main seal on the two halves, need to pressure wash it to be absolutely sure though...LOL what's the nylon thingy?? Share this post Link to post Share on other sites
oldredrider 2,547 #7 Posted June 19, 2015 Technically, it's the cam plate. The shaft it operates on the front of the motor has two o rings that fail over time. If that is the area where it is leaking, you found the problem. Share this post Link to post Share on other sites
pfrederi 17,147 #8 Posted June 20, 2015 O rings are #52 and 55 both NLA but you should be able to match them up at a good hardware store or hydro repair place. The gasket between the hydro gear and the transaxle is also NLA... Gasket material and a scalpel 1 Share this post Link to post Share on other sites
