Gimbal Bearing Removal and Replacement (Video)

Welcome to Mallory Marine. We’re going to demonstrate the removal and replacement of a gimbal bearing on a Mercruiser Alpha Gen 2 drive assembly. This procedure is similar with other brands of outdrives as well.

Step 1 - Place the outdrive in forward gear.

Step 2 - Make sure the drive is in the down position and as vertical as possible.

Step 3 - Remove the outdrive. Remove the trim rams, the nuts holding the drive, and the speedometer pick up tube.

Step 4 - It is always a good idea to check the engine alignment prior to removing the bearing.

Step 5 – Remove the gimbal bearing using the Mallory Marine puller. Part number 9-79820. Follow the enclosed instructions for an easy removal. For a more detailed video on the puller itself, visit Mallory Marine’s website, or YouTube.com.

Step 6 – Install the bearing. Mark the outside face of the carrier to index the grease hole in the side of the carrier making sure the tolerance ring does not obstruct the grease hole. Using the proper mandrel tool, drive the bearing in place making sure you have aligned the mark previously made with the grease port in the transom housing.

Step 7 – Grease bearing. Locate the grease nipple on the right hand lower transom housing and pump grease into the gimbal bearing until you see it coming up around the bearing.

Step 8 – Check engine alignment. Install the engine alignment tool again making sure the alignment is correct. You should be able to turn the tool with two fingers when properly aligned.

Step 9 – Preparing drive for installation. Install “O” ring on yoke shaft and grease spline with spline grease. Install gasket and water passageway “O” ring. Grease shift slide making sure it is properly aligned. Grease u-joint assembly if equipped with greasable u-joints.

Step 10 – Install outdrive. Align yoke shaft through gimbal bearing and into engine coupler. Make sure drive is in forward gear by only pressure on propeller and pushing drive into place. Install retaining nuts, trim rams and speedometer hose.

Thank you for viewing. For further information and parts go to iboat.com.

If when running you hear a grinding sound, check this bearing. Also while you have outdrive apart check your bellows to make sure no cracks.

Full StarFull StarFull StarFull StarFull Star1988 OMC King Cobra gimbal bearing
by David from North Liberty, Iowa on July 19, 2012
The gimbal bearing fit fine. Removal was a little more challenging. Went to Autozone and got a loaner bearing puller and slide hammer which worked well. An alignment tool is necessary to loosen the new bearing and properly align the shaft. The Sierra gasket set gets a thumbs down for the gimbal bearing 'o' rings that go on the shaft. They were slightly over sized and made installation of the outdrive impossible. Bought an OEM gasket kit and installed with 'o' rings with oil as shown in manual and had no problems replacing drive with one person and no hoist.

Full StarEmpty StarEmpty StarEmpty StarEmpty StarMade on Friday at 4:00pm
by Jeff from Eden Prairie, Minnesota on April 26, 2012
well someones having a bad day or bad week or bad month, I have ordered and returned 2 of these in a row because of poor manufacturing, bearing is off center, and misaligned, apparently who ever is stamping these out, is allowed to drink beer on lunch hour, Or Sierra has no quality control program. ON both bearings I received it is so misaligned you can see it plain as day one side of the insert is about 0.1 inches offset from the other side. In other words if you spin it around it will wobble about 0.100 inches,

Full StarFull StarFull StarFull StarFull Starquality bearing
by Bryan from Big Lake, Minnesota on April 17, 2011
Matched up to the one I took out of my alpha one, went in with no issues. Just remember to have a decent slide hammer or removal tool as the old one came out hard. There is also a seal behind this bearing you may want to replace at the same time. iboats rocks, shipping is very fast. Ordered on a Wednesday and delivered here in Minnesota on Friday with standard shipping.

Full StarEmpty StarEmpty StarEmpty StarEmpty Stargimbal bearing
by Robert from San Antonio, Texas on May 31, 2012
After many emails to see which bearing I needed and then ordering the one Iboats suggested, I took my boat apart to find out it was the wrong one. The bearing seams like a well made part but I just couldn't use it.
