Re: OK, how do you get the bearing off the shaft?

MB, when I mentioned the bearing cages, they are the ones on the piston rod big end, when you take the rod bolts off you will have needle bearings and the cage, on mine I found two cages had cracks on the outer part and one cage had the center spacer lying between two needle bearings. I am glad I checked them as the motor (1972 l6 140hp merc) would have failed. It is a good feeling when you find a problem before the possibly of damage. If you watch youtube under Buzz's Glastron you will hear the motor noise and that was what caused me to pull the motor apart. In Pa. winter is here and I want to get everything ready for spring as are seasons are short. Worst thing is fixing the boat when you should be out enjoying it. Buz

Re: OK, how do you get the bearing off the shaft?

I'm hearing what you all are saying. I can't afford a new motor and I plan on keeping this original boat/motor pair. Spending a few $$ now could save me $$$$ down the road. I can see some slight scoring on the skirt of #4 piston, and even though the compression is 140psi, I'm inclined to do a complete teardown and check ALL the bearings and the condition of the #4 cyl. In for a penny, in for a pound as they say.

The one BIG beef I have living here in Canada is the crazy expensive prices we have to pay for parts. I pay easily 2x the cost of the exact same parts in the USA. If I buy from the USA and have to ship into Canada, the resulting cost is just slightly cheaper then buying locally.

I tell you I have gotten new old stock piston with pin and rings for a cheap as 40 bucks. Three used rods 35 dollars. Crank one for 60 and one for 100. New bearings for wrist pins 7 dollars each set conecting rod bearings with cages 20 bucks. I still spent a fourtune. Bearings upper 30 bucks lower same and gaskets as well. All off ebay

MB, this is what you are going to look for 1972 140hp l6 012.jpg Buz

Great picture, thanks. I've decided to do a complete teardown and check all parts and do this right. I've got a few months before the ice comes off the lakes. I will be keeping an eye on ebay for cheap parts.

Many thanks Max. That is a good price for sure.
