Jim's Machining Sprocket Shaft Seal Installtion Tool 39361-69. Use to press oil seal over sprocket shaft into case. Supersprox Rear Stealth Sprocket 45T Gold RST-486-45-GLD. Use with tool PART #DS-196048.
Really a nice tool, BUT the prices are astronomical. This is a quality tool I understand making money, but Jim's Tools are just about too expensive to purchase.
