burnt start capacitor on air compressor

[rgunlock]

Hi, ran into a little problem with my air compressor. Discovered that this capacitor (start capacitor I believe) was burning. This was from a Husky 80 gallon compressor with a 4HP motor.
The capacitor itself had this stuff on the label. Some of it was a little hard for me to read so this may not be 100%.

45.F +/- 5% PO 50/60 HZ
400V ~B <10000h>
440V ~C <3000h> SH
L622851 19/04/06
IEC 60252 61048/61049
Made in Brazil 25/85/2

The brand might be WED but hard to read. Google isn't finding me any exact matches. I pulled up the parts list for the compressor but they only list the whole motor which is $$$. This capacitor is easily replaceable so not sure why they don't list a part number.

Question is which of this information is key if I look for a replacement? Is there any good reason to expect that something else went bad causing this to burn up? Anyone know a good source for these?

Thanks!
