plumb-r 34 #1 Posted December 28, 2016 I was wanting to change the hydro oil in My C-145 Auto, and was wondering where to drain the fluid from. In the hydro manual it looks like the Eaton 1100 has a plug on the back side of the filter housing. Is this the plug I should use to drain the fluid from? Is there another location with a drain on it that I could get more oil out of? Any help is appreciated! Share this post Link to post Share on other sites
pfrederi 17,911 #2 Posted December 28, 2016 Bottom of the transaxle housing. Just to the left front of the hitch bar that goes under the tranny. You need a 1/4" allen wrench to open it. it may be packed with dirt. 2 Share this post Link to post Share on other sites
oldlineman 1,482 #3 Posted December 28, 2016 Just a thought,make sure you clean out the allen wrench hole good so you get a good bite with the allen wrench or you can round out the allen hole and make removal much harder. 3 Share this post Link to post Share on other sites
DougC 2,641 #4 Posted December 28, 2016 I. like said, clean out the hole first, then make sure my 1/4" hex head socket is bottomed out in the plug and use a long 3/8 ratchet to loosen the drain plug. Don't get carried away and over tighten the drain plug when done or you may have trouble removing it the next time. 2 Share this post Link to post Share on other sites
