Hello everyone.
I have an 87 2.9 ranger 4x4 running an old Tecumseh HR980 rotary compressor. Does anyone know how to replace to front shaft seal on these, Ive read they are not serviceable, yet I can find the shaft seals and special tools to dismantle the pump. They compressor has a large leak at the shaft that I can hear while the truck is running. Thank you for any help everyone
Here is a Picture of the compressor
