Re: Has anyone replaced the snout bearings on a gen v?
GenIII to GenV's they are the same pretty much.
You will need a arbor press to do the bearings correctly. This is what I use to disassemble, and reassemble superchargers. Its a 12 ton press, nothing special.
For the DIYer, once the pulley is off, you can, with hand tools, smack the snout shaft with a hammer. You will have to use a steel headed hammer, a rubber mallet, or dead blow hammer wont cut it. Hit it straight, and it will come out.
Once the shaft is out, you can take a 21mm or 22mm deep socket and a long extension. Put the extension in the socket backwards, so you have a BIG surface on the back side of the socket to use.
AFTER you make sure the retaining clip is removed from the end of the snout!
put the socket and extension inside the snout, and hit the extension to hammer out the seal AND the outer bearing.
Clean and degrease all parts well at this point.
To remove the inner bearing off the snout shaft you HAVE to hold the bearing while pressing OFF the coupler joint. I do not recommend using a puller and PULL the joint off. This is where you need a arbor press, AND a specialty tool. I made my own tool that goes around the snout shaft and is longer than the shaft once on, so when you press on the shaft, the shaft will press on out of the joint, and bearing, and the shaft will fall below and stop on the press plate. This is very dangerous to try and do yourself with basic tools, and even with a press, things can go wrong. Its not uncommon for the bearing to grenade on you when your pressing it off. 1 in every 30 may do it. Wear your safety glasses and don't stand in front of the press while you work.
You will also need a arbor press to install the bearings.
The reason why you need to use a press is because it has constant EVEN pressure as it installs the bearings. Hitting it with a hammer is a harsh, sudden, and shocking pressure...which can damage the bearing.
You will also need a specialty tool to install the snout seal as well. The replacement seal is most likely what you removed, metal with a coating on the O.D. that's a seal against the case, and a rubber inner seal for around the shaft. You have to open the inner seal up, and hold it while you install it on the snout shaft, or it will curl on you, and ruin it. Also, you have to press the seal in evenly so you do not bend or damage it, or mess up the outer seal around it and it will leak at the seal to snout area.
$50.00 labor, ($80.00 non members) same day service, you supply the parts and I rebuild and ship it back.

right?!?!?!
