Common issues with the T800 Kenworth Truck.
This is going to be by no means a comprehensive list but it is just some of the more common things at G.B Truck and Diesel we have seen while repairing, rebuilding, and servicing Kenworth engines in Edmonton
Fog lights: They always seem to be problematic on these Kenworth trucks and especially if you got an ally Ark bumper, then usually you are going to find wiring issues or corroded wires. Check the fuses first that are the easiest and of course the bulb itself but if both are out then the chances are it is not just the bulb right. Usually, the wiring comes down the driver’s side of the Kenworth truck, and then it crosses over from the driver’s side to the passenger’s side. It means it depends on how the Kenworth truck was rigged up. Sometimes the wiring can get messed up in middle there in between the two lights.
Hoses, the emissions system= If a Kenworth truck has a lot of miles offroad, these bolts in the back brake or work themselves loose and fall out. So always have something to check for on the Kenworth T800 especially. The front ones are not too bad to get at but the back ones, of course, you have gotten your DF tank in the way, so they are a little trickier. A lot of times you end up, taking the step off if they are broken, so you could drill those bolts out and put new ones in . This is something we have seen day in and day out while repairing, rebuilding, and servicing Kenworth engines in Edmonton at G.B Truck and Diesel.
Springs Bend: Another problem with these Kenworth trucks is on the front Springs on the drug bursar around the steer axle. They have a band that goes around the springs to hold them, so sometimes those Springs bend and then they are bad enough that they will start hitting on those blocks. So, usually, we will take those Springs off get them straight again and get one of the brackets welded on, and reinstall them.
Stack bracket=Sometimes you will get that vibration or a noise rattle. Sometimes, it is the stacking bracket on the passenger side of the driver side will start to wear, and eventually it will break, and then the whole exhaust assembly will shake and rattle, and sometimes you can even see from the shield it will come around and mark on the side of a sleeper so they are not too hard to replace but something to keep an eye if they break and eventually in case you ignore it t could lead to costly repair on you Kenworth heavy-duty truck engine. Diagnosing the fault at an early stage by G.B Truck and Diesel will help save a lot while rebuilding, repairing, Servicing, and overhauling the Kenworth truck in Edmonton.
Your cruise control or high idle switches: You know if the Kenworth truck is not staying in high idle or will not go into high idle. A lot of times the clutch linkages get worn out so you can tell from the symptoms like the clutch will stay down and if you pull it up then all of a sudden it starts to work again. So, what the problem actually is underneath the cab of Kenworth Truck. It is the clutch linkages and they are kind of a ball and socket there and they get seized up, so you are going to have to replace those and those linkages they come from Kenworth with the new balls and sockets.
Fuse Box: If Kenworth truck lights start doing weird things like all markers are out or signals coming on with the brake lights or vice versa, a lot of times, check inside of the fuse box. Go inside this fuse box, there are fuses for the chassis node. The chassis node controls all your lights and so if any of the fuses are blown fuses, then you are going to see some weird stuff happening but also with that chassis node. If all these fuses are good and you are still getting weird issues with the lights, a lot of times it is the chest you know that is problematic.
Checking these small things would help to reduce the repair cost of the Kenworth truck in case it would require service, overhauling, rebuilding, or repairing of its engine.
Type of Engines that Kenworth heavy-duty truck uses:
MX-13 engine is Paccar indigenous engine and it is now available in Kenworth trucks. It has been on the market here since 2007. It is rated at 460 horsepower of 510 horsepower and puts out 18 50-foot pounds of torque in the DAF. It is backed by a 16-speed ZF transmission automated but in the Kenworth heavy-duty trucks, it is backed by an Eaton transmission.
The advantages of Mx-13 engine in Kenworth truck
LIGHT AND TOUGH:
It is a CGI construction that is really light and really tough. MX-13 engine in Kenworth truck is the ideal engine for bulk applications and tipper applications. The MX 13 engine in Kenworth is significantly lighter than other Kenworth engines that have been used in the past.
UPTIME:
MX-13 motors for Kenworth trucks are built for strength, with a B10 design life of over one million miles. Each MX-13 engine comes standard with inaccessible diagnostics to provide focused uptime support.
EXCELLENT FUEL ECONOMY
Fuel reserve funds are one reason the PACCAR MX-13 in Kenworth trucks continue to pick up ubiquity within the heavy-duty market. Low Taken a toll of Service With up to a 75,000-mile oil alter interim, MX engines will spare your trade cash due to the low cost of schedule support over the life of the engine in Kenworth trucks.
WEIGHT SAVINGS
Less motor weight Implies pulling more payload with each trip. The PACCAR MX-13 In motor provides Kenworth truck proprietors up to a 450 LB. weight investment funds over 15 L. engines.
SUPERIOR EXECUTION AND CALM OPERATION
An MX motor has wide torque bends, so it requires less moving, and the calm operation improves the driving involvement
Rebuilding a Paccar MX 13 Engine for Kenworth Trucks
We would rebuild a Paccar heavy-duty truck engine. We have got parts for the Cummins MX13 engine. The first thing we need to do is get the crankshaft installed. We have got the cylinder block all cleaned up. The next thing to do is install the main bearings and just like the cam bearings make sure that the oil hole is lined up and the lock tabs on the band Install the tamp side first. Now we are going to lubricate the bearings. It is time for to fire service to choke up and set the crankshaft. Next, we going to install thrust bearings to oil groove out. The thrust bearings control the end play of the crankshaft. Next, install the main bearing caps. We want to make sure and keep the surface between the cap and the bearing dry and these are marked front. It is also important to make sure you lubricate your cap bolts on the threads and on the shoulder.
The oil clearance is the amount of space between the bearing and the crankshaft. Before we assemble all these caps. We have to check the oil clearance. For that, we are going to be using a tool called a plastic gauge. So, we are going to cut small pieces of plastic gauge and set them on top of the crankshaft journal, and bolt the cap down. The bearing is going to crush this plastic- gage and that crushed plastic gauge will tell us how much clearance we have. Proper oil clearance is critical.
The next step is to rotate the bolt to 180 degrees. Now that 180 degrees are actually going to stretch this bolt to ensure that it does not come loose. Every time we tighten one of these caps see this 180, we are going to rotate the engine 360 degrees. So, we have got our crankshaft installed now. Next install cylinder liners, get these lighters sealed up, and get them installed into our engine block. When this is installed in the engine block, the top end of this line is going to be surrounded by engine coolant. We need to keep that engine coolant up here and out of your crankcase. And that is where these O-rings come in. These seals are going to have to be lubricated. Just make sure to remember not to use petroleum-based lubricants. This manufacturer actually calls for vegetable oil. The next thing we need to do is check the line of protrusion.
Next, It is time to install pistons and rods. Keep in mind there are two types of rods; drilled and non-drilled. It is time to get the rings on this piston. We have got three types of rings. We have got our compression, which would be the top ring, intermittent, which is the middle ring, and the oil ring which is the bottom ring. The next step is to install the piston cooling nozzles and what this does is receive oil from the engine oil pump. It squirts it out to the bottom of the piston to lubricate and cool it. It is important to check these for cracks. If these fail, the piston overheats and you junk a cylinder.
