Need your opinion on the broken shaft 1-2
Was it equipped with RBB? was the apply accumulator checked?
Not sure for RBB we have the hte 125 pn 22579.No test has been performed! The dealer asks us 22k for the replacement of the shaft...which accumulator is to be checked ? Thanks for ur time
I don't recall if the mid size 60,70,90 had it . It's an option called reverse by braking. You could travel full throttle towards a pile, change direction to reverse (like a hydrostat) the brakes would automatically slow the machine to a speed where the direction change was reasonable. It requires a pwm valve and accumulator mounted over on the R/S beside the trans. Does the machine roll ok? Any diff problem? There are circumstances which cause the front axle diff lock to engage without warning or indication. Is there any chance the operator was in a wheel spin and suddenly got traction? That is certainly not a common failure.
we are in Quebec so yes there is ice on the ground that could be a possibility otherwise the machine was working well and the differential does not seem blocked In the last year we have noticed that the gears take a long time to pass, maybe a clutch pack can get tired.
Clutch would only allow slipping. Wouldn't cause this kind of failure unless 2 ranges fully applied at the same time. That would've showed up as excessive clutch wear, oil would've turned black in short time. That's a sudden catastrophic failure, plus overheating. That is shock load. Make sure those front wheels spin independent of one another.
the oil is good up to date filter also I await the decision of my superior if I do the job I would like that I check the differential if it is not lock monday I will get back to you with more info Thanks
The beach marks shown in the second photo indicate a progressive failure, usually from a flaw in the part. What does that shaft do?
Clutch shaft in transmission
[QUOTE = "funwithfuel, post: 940118, member: 63426"] L'embrayage ne permettrait que de glisser. Ne causerait pas ce genre de panne à moins que 2 plages ne soient pleinement appliquées en même temps. Cela se serait manifesté comme une usure excessive de l'embrayage, l'huile serait devenue noire en peu de temps. C'est une panne catastrophique soudaine, plus une surchauffe. C'est une charge de choc. Assurez-vous que ces roues avant tournent indépendamment les unes des autres. [/ QUOTE] the front wheels do not turn independent When we block a wheel I am able to raise my colleague the front axle seems to be locked
With front axle off the ground and parking brake set, the wheels should turn in opposite directions. If its locked or tries to turn in the same direction, you're going to have to investigate the diff lock in the front axle.
looking at it is not locked the wheels turn in the opposite direction one from the other one should be correct
Try with the engine running.
Have you done any further disassembly? You may find more wrong internally. It is strange to see a failure at that point as that is just the support for the end of the shaft
my boss decided to send it to the dealership $$$$$$$$ I lost the opportunity to have a good challenge I will keep you tuned as soon as I have any news
That is an uncommon failure that isn't supposed to ever happen. By having the dealer involved your boss may ask for special consideration. It's not warranty, but never should have occurred. Good luck
The failure coverage will depend on age, hours, application and general condition of the machine. Anything can happen on any machine and generally does. There is no phrase "not supposed to happen" in any warranty manual. I usually worked with a customer more when they would describe something as an unexpected failure that wouldn't be expected within the parameters of machine operation. A hole in an engine block in a machine 500 hours past the warranty period with the dealership doing the maintenance would be an unexpected failure that would receive policy consideration. That same problem happening at 8,000 hours with the owner not being able to prove recommended maintenance was accomplished would likely receive no consideration. That machine that was 500 hours out of warranty with no maintenance records and obvious indications of problems like plugged fuel filters, plugged air filters, plugged radiator fins and obvious fluid leaks would have a hard time proving that the failure was caused from defective material or workmanship.
The work environment is icy with asphalt at the end I think it could be plausible as said funwithfuel Machine has 14 000 hrs +/- Maintenance is good oil look very good too The machine must climb a good slope to be able to empty the sand then it moves back the slope about 40 50 x per day with the freezing weather conditions of Quebec Thanks for your help, stay tuned
