Have Questions?
Are you tired of dealing with a leaking bowl? Then this conversion kit is exactly what you need! This kit allows you to upgrade any HCM 300/450 to the newest bowl seal design. This new design provides the best leak protection available for the HCM. With our complete step-by-step directions and a few basic tools, you can convert your HCM to the new seal plate design. Before you purchase this kit, please read our recommendations for additional parts.
NOTE: This may not work with older style brake assemblies. If you still wish to use this conversion kit, you may have to remove the brake and purchase a JPM spin off disk.
Recommended Parts with this Job:
#1: JPM Spin off Disk. This low profile, double sealed spin off disc will disperse any water that bypasses the bowl seal. This spin off disc is required when using the bowl seal conversion kit, as the larger OEM style does not have enough clearance for the seal plate locking nuts. If your HCM has the brake feature, this spin off disc is not required.
#2: Upper Motor Oil Seal: This is a secondary seal that prevents liquid and debris from entering the upper motor housing. This part is also included with the HCM rebuild kit.
