I'm working on a 1967, 10hp Mecury, model 110. I replaced the reverse bearing and I was wondering how I should press the bearing into the bearing carrier and how much pressure to use. The carrier is made of a soft metal and I don't want to crack it. <br /><br />Thanks

Re: 1967 Mercury lower unit

If I do not have the heat gun available, can I use a standard propane torch to heat it up?<br /><br />Also, how far should the gear go into the bearing? I have it flush with the other side of the bearing but there seems to be a little bit of play with washer that goes between the bearing and the gear.<br /><br />Thanks again

The gear should go into the brg. till it sets against the boss on the shaft. When using a propane torch, just use care not to get a ot spot, move the heat around as you are heating it. You need to get it hot enough to expand the metal be not harm the seal---Bob

A trick we used to use on flywheel ring gears was to heat the wheel with a heat lamp or hair dryer (those halogen shop lights work great and get pretty hot) and put the ring gear in the freezer. Worked great for flywheels and races when you have a lack of proper tools.

I found a heat gun and it worked great. Just a little tap and the bearing fell right in. Thanks for the help.
