In this video i talk about some changes I am making to our cast bell program. These bells are now made in the USA entirely, they are cast in Ohio, and machined in Pennsylvania.
I am also going to talk a bit about a few rare instances we found where JZ blocks varied in tolerance and how that affected the bells runout. We machine these within VERY tight tolerances but unfortunately the toyota blocks seem to vary more than i thought.
In the past year I have sold over 350 bellhousings, and of those 350 only 4 have had issues with indexing, so it is VERY rare, but just to ensure that all bases are covered I will be including index plate rentals with every cast bell. It is better to check and find that it is OK. There are too many tolerances that combine which can create a runout issue.
Sorry for the one-take video I did but it should explain everything pretty clearly
