Jass Performance Rear Crankshaft Oil Seal Tool For Mazda MX-5 NA & NB


Handy and time saving tool for installation of the tricky crank shaft seal. Spot on installation each time, without danger of harming the seal or the crank shaft during the installation.

This rear main crankshaft seal tool is used in conjunction with the flywheel bolts to provide even pressure, a very awkward seal to install without due to its size.

    Waste of money, finished doing the full clutch/flywheel job and fitted a new rear main seal using this tool. I now need to take everything off again as the rear main is leaking. I would expect using a tool which is specifically designed for one job to make the process simple and reduce any chance of incorrect fitment to basically nothing, assuming it is used correctly. I will use it again to get the seal on the crank, but will be far better off using a hammer to finish the job properly. This is a real shame as everything else I have bought with BOFI, along with their customer service, has been excellent.
