These 3 tools made only by JR Marine are a quick and easy way of removing or replacing tapered shaft bearings. Each tool size comes with a heat treated extractor bar. This bar is 14" long and will fit on all 20 and 40 ton hydraulic presses. Simply place shaft in extractor bar, place in press and remove bearings. To replace bearings, drop hardened installer bushing in extractor bar hold and replace new bearings on shaft. 100 times easier and faster than using a bearing separator tool. Comes in 3 sizes.

This unique tool also made only by JR Marine enables you to test lower Bravo 1 housing for leaks due to cracks or fractures in the aluminum or leaky seals after assembly. A unique way to test PSI without bolting upper and lower together. Also included in this kit is a special locating ring with seals pressed internally to seal vertical shaft. A must for the rebuilding shops!

Extractor bushing is made from alloy material, heat treated to a Rockwell Hardness of 48-52 RC. This bushing surpasses OEM quality by far. It has the same 5/8-18 thread as the OEM, which enables you to use your existing threaded knockout rod. Replaces OEM #91-89867T.

This extractor bushing is also made of alloy steel and heat treated. The unique feature of this bushing is that it will help contain the edge of the race when extracting. Which means almost every lower shell vertical shaft bearing can be removed without the bearing cage breaking. This bushing should be used with extractor "A" bushing for the best performance.

This installation bushing is also made of alloy steel heat treated to 48-51 RC. Unlike the OEM install bushing this install bushing has a larger surface on the roller bearings when installing which creates the bearing to install more evenly. This bushing can be used with OEM 5/8-18 threaded rod if you use JR's threaded rod nut part #1018.

This tool replaces OEM #9163638T. This unique tool is made of alloy steel and heat treated as are all of JR's tools. It is longer than OEM which enables you to turn threaded rod nut 360° without running into lower case studs. The bearing installed in this tool makes installation a breeze with no pressure. This tool is a must!

This is the insert which fits into the bearing of the housing tool. It is also alloy steel and hardened and will never wear out in the application for which it is used. This part fits into JR's part #1004

This nut is a 1-1/16" hex hardened flange nut. It has a 5/8"-18 thread and must be used with JR's extractor B, and install C bushings.

This threaded rod replaces OEM #91-31229. We use a hardened threaded rod with a 1-1/8" hex wrench body top. Top wrench body is also heat treated to be able to use as an extractor with a hammer, or with an impact when installing. This threaded rod tool is a must if you want quality and durability.
