My sears model 917.2737 What is causing a spring popping noise in the mandrel assembly area on one side?.

I don't think you're using the right word "mandrel". I will need a little better explanation of what's going on and where exactly.

Well if you are breaking mandrel housings you are hitting more than grass with your mower. They are not intended to be used as brush cutters or mole hill graders. Also, if you have broken a mandrel then you may have slightly bent the top of the mow deck where the mandrel housing bolts up. In order to see it you will need to remove the mandrel housing and use a straight edge to ensure the mounting surface is straight. Quite often you don't need a straight edge; the damage is visible. Typically it will look like a dimple where the bolt head was sitting on the top of the mower deck. With the mandrel off you can use a hammer to pound the surface even. Sears also sells a reinforcement kit to make the mandrel mounting surface more sturdy or you could use fender washers to sturdy up the surface, but the kit is best as it gives support around the entire rim of the deck housing.

If your blade will secure on the star, just jam the blade with a block of wood and proceed. If you have ruined your star, remove the three bolts that secure the mandrel housing, allowing the pulley to drop down to the deck (this requires some room beneath the deck, so get the whole thing off the ground first) and secure the pulley with heavy wire to the deck. There are a couple holes in the pulley and those bolt holes in the deck. Twist tight. The nut is threaded normally (counter clockwise to remove). A socket with a long handle does the trick after you use a few drops of break free oil.

Have 54 inch Craftsman mower deck that I am rebuilding - how do I remove the spindle from the Mandrel housing? Appears to be stuck but will spin.

Depends on how old the deck is. Some of the older spindles and mandrels were not made to came apart. The newer ones you can put the nut on the top threade to protect the threads and a couple of taps it should come out. If you have a model number you can got to sears web site aa they will have an exploded view.

Mandrel where blade attaches the slotted piece is gone

i'm guessing that you're referring to the aluminum mandrel housing: yes you can get the housing separately, better get some new bolts too, because the old ones will likely break off - use some anti-seize compound on them and it'll go alot easier

Needing to replace the mandrell housing

I assume you're refering to the round aluminum housing with bearings in it? It's a pretty common part. #492574. The problem you may be having is that they show the part # to be 492474 on the breakdown, but that is incorrect.
