LT 1000 mandrels that don't fail in 2 days?

[2xLT1000]

Any advice on buying spindel mandrels for a 917288810 that don't fail after mowing twice?
I ordered from Sears Parts Direct 2 months ago and finally had to cancel as they were never going to come in. Again.
I've been ordering from random suppliers but they all break at the 3 bolt holes that hold them to the deck. One mandrel is original to the mower. The other I've replaced 5 times! Either the housing fails or the bearings explode or both.
Any advice on a good source would be appreciated.
Thanks!

Bad model number....Apparently.

Part number for the spindle assembly for the tractor number you posted is 587819701. Problem I now see is these have a four bolt housing, where you say you have a three bolt housing. 2+2=???? Can you clear this up?

The OP indicated he has three point mount not four point. Depending the actual model of the mower there maybe a heavy duty version available.

As I said, I used the model number he posted. That’s where I got the four bolt housing. He’s going to have to give us more and better info to clear up what he has in front of him.

All apologies, I had written both model numbers down and mixed them together when posting.
I have a bad habit of doing stuff like that. Sorry for the confusion and grateful for the replies.

The 917.271811 comes up with the 532130794 spindles. Rotary makes a heavy duty version of that spindle under PN 15177. Google using "Rotary 15177" and you will sources online or you could go to a local Rotary dealer and have them order them for you.

That number works better and I have three things that could contribute to you problem. Before getting more new parts I would be checking to find the cause. Check the following.
1. Wrong belt putting too much tension on the assemblies. Belt should be part number 532144959. Length should be 95.5”.
2. Housing not staying tight to the deck, due to enlarged holes, bent or sprung deck,
3. Wrong spindle assemblies ore spindle pulley. As Star said Assembly should be part number 532130794 And spindle pulley should be part number 532173436.
4. Is the tensioner arm and pulleys keeping constant pressure on the belt, not allowing it ti flop around.
Something is causing the problem and seems you are having continued problems after replacing parts you need to find the cause before throwing more parts at it.
