Diesel pusher chassis
Diesel pusher motorhomes are hardy autos, however they’re not indestructible. Right here’s an inventory of seven doubtlessly damaging diesel pusher errors that house owners ought to keep away from.
• Fueling from either side on the similar time. Most diesel pushers (DPs) have gasoline ports on either side. Truck gasoline stations usually have a grasp pump on one facet with a slave pump on the opposite. This accommodates the filling of separate saddle tanks positioned on both sides. They don’t seem to be for filling a single tank of a twin ported automobile. Doing so will result in a critical gasoline spill whereas pumping.
• Making use of arduous utility of the service brakes whereas the park brake is engaged. Excessive air strain mixed with the highly effective spring brakes positioned within the tandem air chambers on the drive axle can injury the mechanical rods and linkages that management the brake motion. Happily, all trendy air brake autos have an anti-compounding valve designed particularly for this subject. It reduces air pressures being utilized throughout such occasions. No matter this characteristic, it is not uncommon follow to tread evenly as to not rely solely on such security gadgets.
• Pumping or dragging the service brakes whereas slowing or checking velocity. Pumping the air brakes can trigger the exhaustion of quantity of compressed air in extra of what the compressor can produce. Dragging the brakes could cause speedy overheating of the brake system. These actions can cut back the effectivity of the braking system and presumably result in complete failure. Air brakes needs to be utilized briskly as wanted and launched.
• Transferring the automobile previous to it totally airing up. Most DP’s should be at their freeway experience peak with the intention to have sufficient wheel clearance between the entrance tires and the fenders. Moreover, driveline common joints may be careworn by the acute angle that exists when the air suspension is totally down.
• Shutting down a sizzling engine or whereas above idle velocity. Diesel engines should be allowed to chill down briefly previous to shutdown. That is primarily wanted for a turbocharged engine. It requires solely about 3 minutes and in lots of circumstances has almost elapsed whereas pulling off the highway. Additionally solely shutdown whereas on low idle to keep away from doable turbo injury.
• Checking the fluid degree of an Allison transmission utilizing the dipstick of an digital fluid degree outfitted set-up. For models with this characteristic, the producer recommends the usage of the digital methodology as it’s way more correct. The miserable of the up-and-down arrows concurrently on the shift pad shows this characteristic if that’s the case enabled.
• Storing a DP with a tank stuffed with 20 p.c bio-diesel mix (B-20) gasoline for a length of over 90 days. Engine maker Cummins recommends not storing autos with excessive bio-diesel blends (B-20) for over 90 days as gasoline system part points might happen.
Nicely, that’s among the DP proprietor’s “no-nos.”
