PILOT BEARING TOOLS, INSTALLER & REMOVER
Mazda Rotary Engine Pilot Bearing Remover and Installer Kit
Mazda Rotary Engine Pilot Bearing Remover AND Installer “Kit”
“Kit” is simply both tools. Since the main one is the Remover, we thought we would include the inexpensive Installer also – makes life a little easier.
The Rotary engine needle bearing pilot bearing can be a REAL pain to remove. It really should be changed at every clutch change. We have seen eccentric shafts destroyed when trying to remove the bearing (obviously without the tool). That is REALLY bad when the engine is still assembled.
Yes, there are cheaper remover tools out there – most do not work at all. The main problem with them is the needle bearing is caged, and the outer “cage” (which is thin) MUST also be removed, and those tools will not grip that outer sleeve / cage correctly.
Btw – we bought and tried that ~$50 one from Harbor Freight. Honest answer on five eccentric shafts: It removed two with medium labor, it destroyed two (pulled all the needles out but left the outer sleeve / cage) BUT we were able to finish the removal with our correct tool), the fifth one was destroyed so bad it would have needed to be ground out. We have heard of other methods that some people have had success with — Your call – we know this tool is not inexpensive.
With our tool it should take less than 15 seconds! Insert end, tighten long part into end, 1-3 slaps with slap hammer and it is out. Installing a new one is simply put bearing on Installer, and hammer it in (that second step on the installer sets the depth). THEN install the pilot bearing seal using the same tool. Btw – do NOT hammer the bearing in with the bearing seal at the same time.
PILOT BEARING REMOVER TOOL
Pilot Bearing Remover Tool
To remove the old pilot bearing the bearing MUST be gripped at its front end. Very few of the aftermarket pullers we tested were able to do this correctly. They often tended to destroy the bearing making removal even harder.
To use the tool simply insert the attachment into the bearing, being sure to get it to the end of the bearing, insert the tapered / threaded end of the slap hammer part and screw them together until the bearing is firmly gripped. Then just “slap hammer” it out. Should take less than a minute.
This tool prevents eccentric shaft damage when removing bearing.
