[QUOTE="krabill, post: 132927, member: 23026"] Thanks to this forum My 853 is back alive! No major issues putting the pump back together and the engine back in. The M46 pump gasket kit I bought did not have the correct O rings that go in between the right and left side pumps so I had to order them directly from bobcat (as well as the two replacement broken bolts) all this work for two broken bolts! The gasket kit did have most of the other correct O rings and gaskets. For anyone doing this, it took me about 8 hours for the engine removal a few hours to mess with the pump and then about another 8 hours of it going back in. I did all the work by myself, there is not much room for another person to help anyhow. Also the fancy engine hoist is very nice, but if you only had a forklift that would work ok to pull the engine. BTW, that hydraulic pump is HEAVY!!!!!!!!! I make a makeshift stand for it and lowered the engine/pump down until the pump set on that stand then I took if off from the engine. Last tip, nowhere in the manual it says to unplug your fuel sending unit wire. I didn't realize it was still plugged in and it snapped off the head of the sending unit when the engine came out. I ordered a new one and it was quite a pain to get the plug in with the engine almost in place but it can be done! [/QUOTE]
