I installed a stuffer and inducer in my Berkeley 12JG jet drive a while back. Now the shaft for this Berkeley pump needs to have a new register machined on it to accommodate the inducer. My pump had a new 174 shaft already set up to my jet drive and impeller combination. So I sent that shaft in to be machined for the inducer. The vendor ended up exchanging shafts with me. They kept my old shaft and sent me an entirely new one. Well, I didn’t catch this till much later once I got around to installing it into the pump. Well, the new shaft moved my impeller rearward nearly ¼ inch. Because of this, I cannot get my bowl installed because the impeller is sitting too far rearward and interfering with the flange. It's an honest mistake that is neither the vendor's nor my fault. In this video, I will talk through the problem I encountered with the inducer and how I checked and measured my shaft, so I could have the issue corrected. While at it, I also needed to have my bowl milled out to accept the stuffer. Also, I will touch on the clearances within the jet drive and how I measured them.

==================================

About AutoTechNick:

Growing up in rural Oregon, I was always around Hot Rods & Race Cars. I imagine my early exposure to this culture ignited a spark of interest in cars, which remains my passion.

I am a proud Alumni of Wyoming Technical Institute, where I studied Automotive Technology, Performance Engine Building & Street Rod Fabrication. In addition to “WyoTech,” I graduated from the BMW Service Technician Education Program, more commonly known as BMW S.T.E.P.

I spent nearly ten years working in various BMW dealerships as a Master Technician. After a move back home to the PNW, I found myself no longer servicing Germanmade machines but now working with Italians. I spent nearly another ten years as a Ferrari Master Technician & Shop Foreman at a local Ferrari dealership.

Ferrari selected me as one of 12 technicians worldwide to compete in the “Ferrari Testa Rossa Awards” for four years consecutively. Finishing in 3rd place in 2016, & in 2019 I was able to place in 1st, winning the competition & earning the title of the “Top Ferrari Technician in the World!”

As my time with Ferrari came to an end, a new career path awaited me…. Aerospace. I am currently working at Blue Origin, helping to build & develop the BE3PM and BE3U rocket engines.

With my new career path, I needed an outlet for my automotive passion, thus the reason for this channel…
