Re: 1967 Travco 270 440 to Cummins 8.3 Upgrade

The motor will not be working anywhere nears its full capability/quite the opposite.. cummins 5.9 is a common swap, and the 8.3 is only 500 lbs more.. tranny is 150 lbs extra.. What are your plan for the bearings, brakes, tires and wheels, steering components? Gas engines aren't real heavy, they hang of the vertical section of a frame and mmounts. You're into a heavy engine, they're mounted from the Physically the 8.3 and Allison is much larger, the weight is spread over much more of the frame. The engine is 48" high, the turbo sits next to the valve cover on the right. The rattling mechanical injector pump sits high on the left of the motor. Measure 48" up from where your mounts would be, that's how much the motor will intrude into the motor home. That is also the noisiest hottest part of of an engine. When I said you'd have to make a new engine cover I meant one that would make it tolerable to ride next to for more than a few miles at a time. When you're talking weights you haven't added in the radiator, intercooler,trans and oil coolers. You've got to find room for those also, they're big, heavy and need a lot of real estate in an area that normally is relatively small in a gas engine vehicle. You've got to plumb them with big hoses that don't like tight bends. Then you have to fill everything with a lot of gallons of oil, antifreeze, and tranny fluid. You need a very large air cleaner and very large tubing that will feed the turbo. Remember, that's on the top of the engine, so it will add to the intrusion into the motor home. One last thing that really bothers me. How long since that engine ran? Just from the picture it looks like it's been parted, you're looking at some big bills for valuable pieces that are missing. The turbo is gone, that exposes the inlet, exhaust, and lube system of the engine Are those sealed up really well?871Views0likes0CommentsRe: Onan Running Problems

Bought the Onan and fit like it was supposed to.....buyer beware..... Al The important specs on a fuel pump are pressure and flow. Bolt holes can be drilled, 3 ft of gas line will probably let you relocate the pump anywhere in the generator compartment, maybe a short extension for the power wire. It's not really a buyer beware situation, just a little innovation to save quite a bit of money.527Views0likes0CommentsRe: 1967 Travco 270 440 to Cummins 8.3 Upgrade
You need to stick with a gas engine. From the picture what you don't have is going to cost thousands of dollars and you're looking at thousands of hours of fabrication. There's nothing about that chassis that was made for an engine and trans that size- you need a new one. You'll lose a huge amount of floor space to gain minimal accessibility to do maintenance. Good access with room for the sound and heat insulation to make sitting next to an old mechanical diesel for hours on end would mean an engine cover would be too big for seats.871Views0likes0CommentsRe: Battery Problems
House or chassis battery? A small light can kill a battery in 2 days. Mine seems to have a light if it has a door, have you checked to make sure everything is off, including bays? Ignition switch off completely? If it's nothing that obvious a DVM that checks amps can be used. It needs to be inline in the circuit, that makes the fuse block the best choice. Once you find the right circuit it's a matter of eliminating components.422Views0likes0CommentsRe: Tiers of Motohomes
I like n0arp's list, it was mine also. Those manufacturers were high end at the time and it shows in their longevity and quality. I also wanted a Gillig chassis, it was used by most of those manufacturers as an option. It means your choices need to be a little older than 2000, but it's worth the search.894Views0likes0CommentsRe: Fuse Panel for Dash Heat Controls Holiday Rambler Gillig
I have a 93 Beaver on a Gillig chassis. The Gillig schematics show pretty much anything in the cockpit goes through circuit breakers. On mine they're just below the windshield under the 'hood' and in front of the driver in a black box. Not sure that will help but it's easy enough to take a quick look.169Views0likes0Comments
