The 3x10x4 Bearings do not want to go into the Head Block at all. The fit is extremely tight to say the least.

The instructions further say to hold the bearings in (once seated) with a 3x5 Philips Pan Head Screw. The bearing is so tight, I don't think it wouild ever come out if it was in the bearing hole.

Is the bearing supposed to be this tight? Are there any secrets in getting this bearing in the bearing hole? I tried light grease but it didn't do any good. I thought I would ask some of those who have done this for the methods they used before I trod ahead.

Any ideas?

Best Regards, Dario

Dario, sounds like something is not right. Can you measure the bearing and the hole, to determine the difference? Those bearings, as with all Bergen "fits", usually go in very nicely. Time to measure, if force is needed!

I think Al has it right. As long as you are making sure that they are going in straight, they should require only mild pressure to put them in the hole. This may be one to direct at Bergen directly.

Thank you Al and Malorie. I truly appreciate your ongoing efforts in helping me. I have been taking your advice as well...no reason to reinvent the wheel.

This is a beautifully designed machine, and an ounce of prevention.....

I just spoke to Larry. He said sometimes the bearings are a bit snug. He said the diameter of the holes in the bearing block is the same as the diameter of the hardened main shaft. He said to run the bearing block down the mainshaft as I am turning the mainshaft. Larry felt this would remove any microscopic imperfections that may be present, thus enabling the bearing to properly seat.

I'll give this a try and let you know.

Best Regards, Dario
