hurst68 0 #1 Posted October 11, 2018 I am new to this group. I have a D-160 with a Newley rebuilt pump with new spline shaft. coupler in very good shape . now my question is should I bolt coupler to the spline shaft by using a bolt and washer into the threaded spline shaft. Thanks for any help you can give me. Share this post Link to post Share on other sites
pfrederi 17,885 #2 Posted October 11, 2018 (edited) Welcome to red square. D series couplers are problematic. There are two service bulletins that explain proper hook up. Loctite RC-680 is recommended. Also note that there are slightly different procedures for Onan vs Kohler. (A D-160 could have either) Click fuzzy picture in links to get to the SBs Edited October 11, 2018 by pfrederi Share this post Link to post Share on other sites
