cutlass bearings
- Thread starter rhiggens

When you take the bearing out you will see what size you need .they are sold buy the diameter of the shaft.Taking one out can be very hard .You have got to cut away some of the glass around the bearing to get to the bolts that hold it in place .Also if you planning on taking out the shaft you may have to do some modifications on the rudder post leading edge.If you need anymore information let me know.Fred

Fred's post may not be true in all cases. The cutlass on my 382 hull 4 was a press fit (no set screws) and held in place by a small amount of calk and pressure on the log. You may have to take a metal "Sawsall" blade and cut a section out of the old cutlass and then crush the tube with a pair of plyers before pulling it out or you may be able to get a pair of plyers on the end of the bearing, give it a twist and then pull the cuttlass out. You may also be able to pull the shaft, remove the stuffing box, put the shaft back in in reverse put the nut back on and use the shaft as a "puller" for the cuttlass(assumeing press fit). For more infomation see the first archive on cutlass bearings. There is a lot of information there.Fairwinds and Rum Drinks,Vic C.

As I sit here at the computer I'm holding my new cutlass bearing which will be installed tomorrow. It's a Johnson Cutlass Bearing, manufactured by Duramax Marine. The model is "Bite" (each different size is given a cute name) and is 1 1/4" ID x 2" OD x 5" in length. The outside surface of the bearing I had knurled because on the 382 the bearing is only held into the shaft tube by friction and a little bit of caulking. I understand that some later models may have the bearing held by set screws hidden in the glass around the tube. Let me know if I can be of further help.

Jim, Thanks for the info. I looked at the two set screws on my 384 and they are simply aircraft type screws place at 12 and 3 O'clock about 1 inch from the end of the shaft log. they are secured with a captive wire. I believe they eliminate any need for either knurling or a sealant which could make it more difficult to remove the bearing the next time.
