Accert front crank seal

depends on your skill level, tools availble, what kind of truck its in, etc. worst case you have to pull the radiator, fan,shroud, etc to access it.

 

depends on how comfortable you are with wrenching on your rig and tool availbility you have. at the least on your w9 you will have to pull the rad supports loose, take the fan shroud, fan blade, belts, balancer out of the way then change the seal, and it will be a little tight but plenty of room to work.

 

there is a tool that is for the seal. a good shop can have it done same day. you said it is in a w900, you don't have to pull the rad to do it. I had the local cat shop come to my shop and install the new seal when I did it, after I had dismantled everything that was in the way. charged me $200 for the service call and installation.

 

I did front seal on my w900l.easy job the only thing is the seal installer cost around 150

 

The job should take no more than one hour. You will need a special wear ring removal kit and the installer which installs the wear ring and seal at the same time to the right depth. Probably better for a cat dealer. You can groove up the crank if you don't know what you are doing when removing the wear ring.
