Air Compressor - NEEDS REPAIR (Westminster)

Craftsman - Model 921.153101
3 Gallon
125 psi
Made in Canada
Needs repair due to item coming on but compression does not start. Somehow a cap came off the motor - It might be oil cap. Worked fine up to 3 days ago. Functioning 4 days ago. Cheaper for me to buy a new one - 6 gallon 200k psi. This may be good for something can tinker with this one.
HOSE IS NOT INCLUDED - sorry.
It worked great, never an issue and used many times over the past 5 years or so. Like I said, it comes on and hums but compressor never engages. Worst case, good for parts.
