Have changed a lot of hoses on 1055B's . They are quite tight to work on no matter which machine. Most of the hoses under that engine are done unless they have been changed out already. The worst thing is hoses letting go in the middle of a job wasting all the labour of people standing around doing nothing till hose gets done. Lift engine out with pump and change all hoses underneath at one time for Thousnds more up front but way less downtime in the future. No wasted oil, damaged paving jobs and yelling and screaming to get it fixed. Wash unit very well to check for engine leaks before removal to make repairs easy to do when out. Or keep adding oil as needed to pump box. Hope this helps. Simon
Also a good time to get radiator work done when engine is out. If tooling is available change out front and rear seal on engine crankshaft. Fix everything that is impossible to get at inside the machine. Once back in machine its too late to make excuses for the cheapout. Just the labour saved in downtime is enormous when a whole paving crew and management are waiting on a fix, not to mention postponed jobs. That is how I see it. Most of the biggest companies i have seen now have accountants tell them which things will be repaired and how. Tripping over thousand dollar bills to pick up pennies. Who needs a mechanics advice anyways. Simon
Hard to tell. I once fixed a splitter box on a pressure truck that was spitting the oil out the breather by installing a second breather hooked up to the top of it on a 1 foot hose and it never shot oil out again. Your gearbox is hooked up to flywheel housing and if the engine vent is plugged it could push the extra pressure into your gear box. Clean the crankcase blow-by vent first.
Its worse when the paver breaks down with a hopper full of fresh asphalt. That 100 degree heat turns into 170+. I have melted the soles of my shoes multiple times over the years.
This is just a personal preference of mine. I would pull the gearbox/pumps and leave the engine myself. My old school thinking doesn't allow me to disconnect items that don't go with the job at hand. Like said above, every hose is a bitch in those and at 8000 hours probably needs replaced. There isnt alot of places that gearbox can leak 90 weight gear oil. Do you know exactly where it is coming from? I had 2 that were pump mount leaks.
With 8000 Hrs the input shaft seal must be hard as rock. Especially with the heat involved with the paver.
