🔧 OTC 7834 Rear Crankshaft Seal Installer: Perfect for Ford Engines! Review

Expensive but worth the cost to fit a $50 Ford 4.0L rear main seal without worry or damage to the expensive seal. Using this tool the seal and bushing snapped into place and there have been no leaks since. Used on 91 Explorer 4.0L

You can feel the quality. It fit perfectly, it was tightened to the correct distance and the lip seal was set perfectly. Most people have to remove the bushing to install the seal, which means poorer performance. It's an expensive one-time use tool, but it's cheaper than removing the transmission a second time to repair a previously poorly installed seal.

High quality tool and if I ordered the right one it would work perfectly. The only problem is that the picture shows 3 cup pieces and 3 screws, but I only have 2 cups and 3 screws. Part of the sleeve was missing that doesn't appear to be needed. This is definitely quality and would definitely make sense, but I ordered wrong again. If you are making a rear main gasket on a 4.0 ohm Ranger that Ford will snap into place with a sealed crank bushing, this tool is what you need.
