Dieselcowboy 210 #1 Posted January 28, 2021 Hey fellas I’ve got the spool valve and motion control lever leaking oil on my gt14. Is there any known replacement seal-O ring numbers that work for these or someone who supplies them ? Share this post Link to post Share on other sites

On the last one that I repaired, I took the old O-rings along with me to the hardware store and matched them up. 1 Share this post Link to post Share on other sites
pfrederi 17,866 #3 Posted January 28, 2021 The motion control uses 2 O rings. O rings are identified by a Dash #... You need Dash# 116 and Dash # 026. I use #026S (square profile) as they are easier to install. Can't help on the lift control 1 Share this post Link to post Share on other sites
oliver2-44 9,850 #4 Posted January 28, 2021 Take your old seals to a large industrial Hydraulic Repair Shop. They have tons of O-rings of every configuration and should be able to help you out. Call them first and see if they have they have the numbers Pfederi listed above. if they have those, they probable have the other one you need. 1 Share this post Link to post Share on other sites
Dieselcowboy 210 #5 Posted January 28, 2021 Thank you fellas. I've always feared having to deal with this problem having hydros. Hopefully the install isn't too bad. Share this post Link to post Share on other sites
pfrederi 17,866 #6 Posted January 28, 2021 (edited) Unfortunately the motion control seal maybe a PIA unless you are lucky that nothing is stuck and you have small agile hands.... You will probably have to split the GT-14 which is not a fun project in itself. You will need a 12pt 1/4 inch socket and 1/4" roll pin punch Edited January 28, 2021 by pfrederi 1 Share this post Link to post Share on other sites
Achto 27,751 #7 Posted January 28, 2021 One other tip that helps is to put grease on the O-ring that is pinched in by the metal plate. This will help to hold it in place while you put the bolts back in. 1 Share this post Link to post Share on other sites
Jeff-C175 7,203 #8 Posted January 28, 2021 I suspect that the GT is way different than my black hood but I discovered that the bolts holding the lift valve together were LOOSE! thus the leakage I was experiencing. If yours is bolted together, check that first! Wish that I had! Share this post Link to post Share on other sites
