S14 Throttle Body Bearings

[ogryry]

Years ago I saw a post here about somebody doing  a complete teardown on S14 TBs and replacing the needle bearings but I can't find it. If I recall, the exact INA models were NLA but they were able to find a comparable replacement.

 

Please help?

 

It's been quite some time since I purchased the S14 and still have a ways to go until completion, but this is the year! 🙂

That's the one.  I replaced the linkage bearings but haven't yet for the throttle shafts because the butterfly screws are difficult to obtain.  Some bearings were available on Amazon and others I went to

123Bearing has sealed bearings that work for the rear axle stub axle bearings.  The next grease cycle I am going to quit messing with grease.

I thought about going to sealed bearings in back, but for raceycar, I was hesitant for thermal management reasons.

 

For streetycar, good idea!

Considering operating temperature build up, sealed bearings operate in high temperature environments, so it wouldn't be that unusual.  Grease in a hub does not have great heat conductive property.   Any heat generated either from a sealed bearing or a grease packed bearing has to transfer thru the hub.   Modern designs do not pack their wheel bearings, sealed bearings are used, so a track record for using sealed bearings is established.  So it's worth a try,

I’ve run sealed bearings in race car. Have worked for me.

When is the last time you raced in temps above freezing?😁
