A few years ago an old experienced mechanic brought his Jubilee to me with a leaking rear seal. The rear seal had been leaking so he replaced it but while he had it apart he threw in new main bearings for good measure. The rear seal still leaked after he put it together. After several attempts with both rope and neoprene seals he couldn t get the leak stopped. Then his shop roof collapsed under a snow load and he decided not to rebuild so he brought it to me. I couldnt get to it right away so my son tackled it. He pulled the engine out, put it on the stand and did a good job replacing the seal. It still leaked so now I tackled it. I put the engine on the stand and while it was upside down I pulled the rear main bearing to have a look and I found the problem. The bearing shell was standard sized and the crank was stamped .010. I put in the right bearings along with a new seal and the leak stopped. I dont know how far you went with your rebuild but while it is on the stand it wont take long to pop a main bearing out to take a look.
