Cummins Generator Maint.
Posted: April 4th, 2022, 5:09 pm
Just FWIW, I dropped my Chinook off at Cummins dealer to have Generator repaired and thoroughly gone thru. It's 21 years old with over 600 hours and recently would not start. Last year I did shade tree maintenance but it never purred (spurted occasionally) as I thought it should and starting up could be struggle. Well recently it decided not to start so I brought to Cummins as they specialize in Onan generators. They had quite a few diesel pushers there.
Shop took out generator and went thru it with fine-tooth comb. It had several issues, Genset not getting spark, Coil Wire shortening due to cover rubbed off, starter beginning to drag so replaced, flywheel removed and bushings replaced as they were very worn and torqued back to spec, carb checked & tweaked, gaskets, filters, and spark plug.
Mechanic said I am good to go for next 20+ years...When I started it up I couldn't believe how easy and smooth it started and it never ran as smooth and quiet since I bought it. Amazing difference.
Not cheap but well worth it.
