I've owned a few motor homes over the years and just have never been all that impressed with the power delivery. After spending a bit of time in Europe and seeing lots of great little campers with 2.5L turbo diesels and many with manual transmissions I just couldn't get the thought of building one out of my head. Nearly a year's worth of research and long nights with my friend Google I finally convinced myself that I could do it. Through a strange set of events I stumbled across a suitable donor engine. A very good deal was made and the truck was mine (minus the original Getrag 5 speed manual).
Here's the recipient:
A 27' Class C on a Ford E350 chassis. In it's original form it had the fuel injected 460 with a 3 speed C6 automatic, 3.54 gears and 30" tires. The price was right and the RV was in great condition. Of course a 450 chassis would have been much better. Or maybe I could have even found a diesel powered one but what fun would that be?
Here's the Cummins out and ready to get torn down:
It's a 1st Gen so all mechanical - easier for my brain to digest.
Although it was running when I got it I still didn't know what the 'noise' was until I got this far into it:
Looks like the injector failed and leaked down for months finally wearing the piston skirts on #4. No problem.
Shiny and new:
Everything else looked and measured fine so I put a fresh set of gaskets in and put it all back together:
Engine ready - now I need something other than the Allison 542 that I got with the truck (wrong high gear ratio)
