Determine correct capacitor

The easy thing to do is take it to a motor shop and ask for one. Sometimes when you order one on line that meets the specs, it’s a slightly different size and won’t fit into the cover.

Be aware that big capacitors store a painful amount of electrical charge, so if you touch it in the wrong way you are in for an awakening, and not a good one.

Also note that in electrics/electronics capacitors are sometimes over stressed by other problems.

50uf is right range for run capacitor on a 5hp 1PH motor. Start capacitor will be ~10-12X that value.
As long you get one with same value, and same or higher voltage, will work fine.
Hard part with motor caps is size restriction.

+1 Easy and best way to get replacement is to visit local motor shop
Might charge $20-30 instead of $10-15 on Amazon, but you will get right size and decent quality part.
Another local source for motor capacitors can be local Appliance parts supplier.
Grainger, or Global Industrial also carry some motor capacitors.

Be sure to check your housing width and length, so you will know if you can use longer/larger cap if needed.

Best Luck!

Don’t run it until you change the cap. There is a small risk of explosion or fire. Once the cap is oozing, its done.

With the saw unplugged short across the tabs with an insulated screwdriver to fully discharge the cap before servicing.

$16 with free shipping for what should be an exact replacement for that capacitor -from ebay. Can probably find them elsewhere as well.
