VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 1929 Clutch Throwout Bearing

I'm taking apart the '29 transmission for inspection, to try to stop oil leaks and to replace the front bearing. I found the clutch throwout bearing (837021 w/ oiler) was installed upside down because with the oiler on top it interferes with the clutch fork. Earlier bearing retainers do not have the oiler. The parts book shows a clutch throwout bearing oil tube for 1929-30 p/n 363441. Can someone describe the oil tube and can I remove the oiler and find or fabricate an oil tube in it's place?

According to the Repair Manual for 1929/1930, the throw-out bearing was not lubricated.

"The clutch throw-out bearing is a Graphite compound and needs no lubrication." (pg 59)

Yet, in 1931, an improved throw-out bearing came with an oil reservoir to be filled with regular motor oil on an as needed basis. I wonder if the oil tube mentioned in the parts book could be a later accessory. It seems though, that it would be easier just to replace the throw-out bearing with the improved type rather than add some kind of oiling system. When I had my transmission out I did not see any kind of oil tube to the throw-out. I did replace the thow-out bearing with a later type but did not add oil to it (see quote above). Haven't had any problems with it after about 2000 miles of use.

The problem is solved - maybe. The throwout bearing and retainer are either for a right hand drive car or it is not a Chevrolet part. I now have the correct part and the oiler is like like the one shown for 837021. I guess I'll have to oil it well and live with it, there's no inspection plate on the '29 clutch housing.

hey d2
do your self a favor and drop the bearing in a pan of oil overnight.

...a good idea

Or, you can get the "No More Graphite Throw Out Bearing" replacement from Verlyn Husman, 6281 Edgewood Ave N. Brooklyn Park, MN 55428

With this, you'll never have to worry about the graphiet thing again.

d2d2,

Just as an FYI. I was looking through some service bulletins and came across this:

It shows the oil tube and how it was installed.

Thanks - that's very interesting, it should be easy to drill the hole and make the tube.
