Velvet Drive Transmission Leak?

Hi everyone:

I have a situation that I cannot figure out. I have just serviced my transmission (replaced seals and gaskets) and re-installed in on my Perkins 4-108 engine. After checking everthing I did a test run to make sure there were no leaks. To my surprise there was a leak from three holes on the flywheel cover on the right side of the engine. I'm sure that is not normal. I there something else wrong here? Or is the transmission seals leaking again? If I have to remove the transmission again I want to make sure this is the problem. Please help!

By the way, It ran smooth.

Mundial

Velvet drives have a history of front seals leaking due to pitting/scoring of input shaft over a period of time. The good news is that they make a sleeve that can be fitted to input shaft to repair it.

The Chief is spot on,it is surprising sometimes how little an imperfection has to be to cause a problem ,nyou can also buy a after market double lip seal slightly wider but fits ok.

Thanks to both of you. I will make sure to check the shaft surface. I assume the shop that made the repair looked at all this, but you never know.
