Throwout Bearing Replacement

by 94_240sx

Overview:

A bad throwout bearing is a common issue for the 240sx, especially since there are still a lot of cars using their original part out there. Most clutch kits (even the cheap ebay ones) come with a new throwout bearing, and servicing the clutch is an excellent time to get this taken care of to ensure a long, trouble-free experience with your car.

Difficulty: ***

Time: 15-30 minutes with transmission dropped

Cost: $35 (separate) or $80-100 (with oem Exedy clutch kit)

Materials:

– Throwout Bearing Nissan pt. #30502 (available at 240sx Motoring and Courtesy Nissan Parts]
– Large roll of magnetic tape or something circular and semi-yielding of the same size

Tools:

– Several sockets of the same height and similar diameter
– Rubber mallet
– 36mm socket or something of similar construction, shape and size.

Procedure:

This is what you are replacing:

Begin by taping your smaller sockets together like this:

place the old bearing sleeve on the sockets like this:

Put a large socket in the middle and just tab it out. You don’t have to hit it hard. I also sprayed PB Blaster a little bit.

It’ll come out like this:

This is a new bearing on release sleeve.

36mm socket fits perfect. Tab it to put the bearing on the sleeve. Again, you don’t have to hit it hard.

It’s not going to go all the way in with a 36mm socket, so I used a roll of magnetic tape like this to push the bearing all the way in.

OEM bearing is on the right side and new bearing pressed to the release sleeve on the left side.

Unfortunately, I found out aftermarket bearing has some play. It moves around 1-2mm like in below picture. I removed it from the sleeve and will buy an OEM bearing. You should inspect the bearing before put it on. I hit it very lightly, so there’s no way it was damaged during installation. Quality of OEM bearing looks much better than aftermarket anyway. Aftermarket bearing came with a clutch kit for free, so I guess I got what I paid for.
