Default Pilot Bearing already in auto LS1?

I'm swaping a t56 onto an LS1 that was originally equiped with a 4l60e. My question is: does my Ls1 already have the proper pilot bearing, or do I need to remove something and put in something else. Any help would be appreciated thanks allot.

I'm squinting really hard, but I can't see your crank from TEH INTARWEBZ. You might have to, you know, crawl up under there and check.

Even if there is one installed, I'd pull it and install a fresh one. Years of gunk accumulating in there guarantees it's not in optimal condition for use.

Nope, there is no pilot, I know bc I pulled my flexplate last night. Its a hollow cavity. Get you a pilot bearing and tap it in. The needle bearings go towards the crank.......I think

Chamfered end of the bearing faces outward toward the trans input shaft, to help during installation.

So your saying that automatic Ls1's do have Pilot Bearings? I guess regardless, I'll drive the 7 blocks and spend 8 bucks at my local auto part store for a new one. Thanks for the help

I'm having trouble figuring out how you got that.

If you hit AutoZone, they have a great slide-hammer kit and puller you can borrow for free...if you find that your engine has a pilot bearing installed.

They also have a bearing race driver set that works great for properly installing the new pilot, definitely get it. Don't use a socket as some have suggested, you'll smoosh up the exterior surface of the new bearing. Use the driver and install the new bearing right.

Hahah

but yea deff just get a new one....and if you cant get the old one out with a puller which didnt work for me cuz the jaws kept slipping out...pack it full of grease and put in something that just slides in the hole and hit it and keep packing it with grease. It was the easiest thing ive ever done.

You somehow got really lucky.

I'd recommend against it. The LS1 crank is hollow, and using the grease ram trick usually pushes the plug out of place causing a big-time oil leak...right onto the clutch disc. Nice trick on Gen 1 and 2 engines, bad idea on Gen 3 and 4.

AutoZone loans a spiffy slide hammer puller set, and a slide hammer to go with it. Haven't found a pilot bearing/bushing yet that this sucker won't get out with minimal fuss.

Don't do this! These cranks are rifle-drilled and sealed with a cup plug behind the pilot bearing. You'll end up driving that plug out of the crank and into the oilpan. Zero oil pressure!
