AMC RULES 37,134 #2 Posted December 22, 2016 Is the tow valve completely closed? Share this post Link to post Share on other sites
Pollack Pete 2,273 #3 Posted December 22, 2016 Tranny fluid level? Drive belt and idler pulley OK? Motion control linkage moving engaging completely? Share this post Link to post Share on other sites
Retired Wrencher 5,516 #4 Posted December 22, 2016 Kavint76 check the Manuals section these can be adjusted after you do what Craig said1st. Make small moves with this ok. Share this post Link to post Share on other sites
Ed Kennell 38,719 #5 Posted December 22, 2016 All of the above easy checks. I think the tow valve on this Sundstrand is a well hidden hex head bolt on the top, left rear of the case. It must be turned in CW. Make sure the keys in the input shaft and axles are in place and the input shaft and axles are not slipping in the pulley and hubs. 1 Share this post Link to post Share on other sites

stevasaurus 22,882 #8 Posted December 22, 2016 When you go to tighten the tow valve, you just need to snug it...do not over tighten.it. You need to open it to push or tow the horse. 1 Share this post Link to post Share on other sites
