This might be a dumb question but here it goes, On my D17 Series 1 on the back on the lift housing, there are 2 bolts where the PTO gaurd used to be bolted, which mine is missing and the bolts are broken off, so we tried to drill a hole in one bolt to get it out and found that someone else tried to get it out be for us (the previous owner) and there is a drill bit broken off in the bolt, so no luck there, anyhow this leads to my question there is oil leaking out of the bolt, not much to worry about, but is there supposed to be oil up that high in the lift housing??? Any help would be appreciated thanks, Steve

P.S. the oil that is leaking is Hydraulic oil.

Mine leaked at a broken bolt in that location; the prior owner had used these bolts

to secure the bottom part of a homemade 3 PH top link bracket.

Leaked mostly (and quite profusely) while driving uphill.

I was able to get the bolt out fairly easily with an easy out; you've got more of a challenge.

BTW I changed the top link bracket so that the lower part is secured by two 1/2" bolts

screwed into holes I drilled and tapped in that nice flat boss a little higher on the lift arm housing.

Seems like a better place to me.

One bolt hole on mine leaked also. Not bad but just enough to make a mess. I had the life housing off this winter and I seen that some cowboy drilled the bolt out and went threw the housing. How I fixed that is I taped it out and from the inside I took a alen head screw about a 1/4" long put some sealer on it and ran it in . So now it dont leak at all. Good luck drilling it out with that drill bit in there. I have pitty on you. Eric

Weld a washer to the broken bolt first then weld nut to washer gives u more meat to weld to so it dont just twist off.

Attempt removal immediately after the welding operation! The heat will likely make it much easier.

Even if you take a torch and heat it up good and hot then let it cool down on it's own, the temper will have been weakened to where you might be able to drill it out. Might use a backwards drill bit as well.

If all else fails get a dremel tool with a diamond tipped bit.Slowly grind away center,including broken bit.Will take a while but you can make hole big enough to get an extractor in.Try welding nut or washer on first,try dremel only as last resort.
Had a broken off exhaust bolt in my Yamaha warrior.Broke extractor off in bolt.Aluminum head,bolt and extractor much harder than head.Worked like a charm.

Heat the casting around the bolt if at all possible. You want the hole to grow bigger, not the bolt.
