Hi folks,

While replacing some injectors of my MY 2000 XJR I'm also doing some supercharger maintenance.A few years ago I upgraded to a Gen V supercharger from the 4.2 L model. After roughly 200,000 km of mileage, I’d like to rebuild it now that it’s already removed from the vehicle.

I’ve already replaced the rear needle bearings and I’m currently working on rebuilding the compressor snout.
However, I’m having big trouble getting the pulley off. I’ve built a puller so I don’t damage the pulley, but even with heat the pulley won’t come off—instead the 10 mm steel plate of the puller actually bends.

Am I overlooking something? Is this the correct method for removing the pulley on a Gen V, or am I missing a step?
Thanks for chiming in and best regards,
Alexander

 

Short update: After doing a bit more research, I’ve decided to modify and reinforce the pulley puller. Instead of using 10 mm steel, I’ll work with 15 mm steel. I’ll also redesign the rear plate so that it provides maximum support for the pulley. I might even fabricate a two‑piece plate to support the pulley all around.
I'm happy about any other suggestion so that I can keep the original pulley.

 

honestly just find a shop with a press. I destroyed two oem blower pulleys and one puller trying to get that thing off, even with heat. With a press it came off easily.

 

Thank you very much for your assessment and experience.

I had already thought of that, but I was worried that I might damage something on the aluminum housing of the snout.
From your experience: Is the pulley the only part that’s pressed this tight to the shaft, or are the bearings the same?

Cheers, Alexander

 

My car pulley wasn't on very tight. I used reqular shop 20ton press. I can not remember how many tons it required.
