953 nut 51,381 #3 Posted November 9, 2016 Fluid level is correct and no leaks, right? Presuming this unit is powered by the Sundstrand Transaxle, is the trans. performing well? is the operator handle on the control valve moving the spool valve? Share this post Link to post Share on other sites
daveoman1966 3,583 #4 Posted November 9, 2016 Was the hyd lift working before, or are you just now adding the hyd lift cylinder to your E-12? If the latter, you MAY need some sundstrand parts., specifically...cone valve. Share this post Link to post Share on other sites

My son has driven it for a while. The hoses are a little cracked but the fluid level in the trans seems to be where it should. It is the red ATF. Thank you. Is there a manual on how the plow should attach? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,474 #7 Posted November 12, 2016 Back in 1970 this was the plow available. It came in 2 packages This may be different than what you have as many plows would fit including the last model in 2007. The main difference may be where the rear axle quick hitch accepts the rear 3/4" round bar on the A-frame - ahead of the rear axle housing or under the axle housing. One is clamped to the front of the housing and the later models are clamped under the housing. Garry 1 Share this post Link to post Share on other sites
Frank in nj 1 #8 Posted November 21, 2016 Thanks Gentlemen for your help. I've been working on it when I can and the spool valve moves ok. What is cone valve and how can I check? One hose comes off the top of the trans the other off the rear. The one of the top of trans is red but that might be repainted. Can I pull that one off one of the control valve ports and check for flow and return? I see the # on the top of the valve is 400 076 and above that it reads PAWICK? If I take a hose to Napa you think they can use the existing fittings? Share this post Link to post Share on other sites
