On a powertec 8000 on my 270 coach is it a big job to replace the bearing can I do it myself or is this a job for a powertec Technician everything is working good sounds good it has 3200 hr just wondering about preventive maintenance is it just a matter of removing the end cap or do you have take the whole generator apart
Take off the end cap and replace the bearing. I am sure that you can do it.
It is not a very hard DIY job. Call Power Tech and give them your model and serial number. If yours is brushless it has a long life on the bearing and Jeff can tell you when it should be changed. The same bearing is available on the web for less than half of Power Tech's price.
Mine Is a 10K brushless 1950 hours. The bearing was changed this summer. It was dry and rough when spun.
That's what I want to know if it was right at the end cap thank you
If your generator is brushless you have to remove the excite coil. Then you will need a bearing puller. Mine had to the externally excited to start making power again.
I believe it has brushes I see a film of brown on the end cover so I believe the bearing is there and it showing signs of wear Time to replace it and is the bearing pressed in the cover or pressed on the shaft wonder if I need a puller
Either way you need a puller to change the bearing.
Another thing I need to look at.
Large removable inspection plate on center: Has brushes.
No inspection plate: Is brushless.
Different bearing part number for brushed & brushless.
Sometimes brushes wear commutator rather then wear the brush. If commutator is too warn it could be major repair. But it may be possible to sand down commutator to level out a grove.
Not only need puller to remove bearing from shaft, it takes some reverse effort to pound new bearing back on and to the exact correct shaft location so it is correctly positioned in end housing.
Then it may take another trick to be sure outer bearing race is tight in end housing so race does not rotate with bearing.
Our gen is 8kw Isuzu brushed, end housing removable without unbolting generator.
thanks for the information
