My dad used to work for Cummins, and his last major project before he retired in 1993 was to set up the Onan shop in Harrisburg PA shortly after Cummins acquired them. At the time I was lacking steady employment, so he put me to work doing a bit of everything, from painting to setting up computers, assembling and stocking steel shelves, to fabricating wiring harnesses for portable generators that went onto utility trucks. The Onans might have had tiny oil filters, but they had pressurized lubrication and were durable and reliable, albeit expensive little engines.
