Hello all,
First post here. Just got my fathers old 68 firebird scrambler running today after 20 years of sitting in a garage. I’m working on getting it road-worthy, and have a few questions:

1. I would like to replace the wheel bearings, part number 42-5819, but I’m having a hard time finding any that aren’t made in China. Anybody know where good bearings can be found?

2. The few grease zerks obviously don’t work with my standard grease gun. Do people usually replace these with different zerks?

3. 2 out of 3 screws on the mirror just spin in place, and I doubt the one that functions will hold the mirror in position at speed. Has anybody taken one of these apart without damaging it?

Thanks in advance. It’s hard to find many resources for these old bikes; I’m glad I found this one.

I believe mirrors were optional so depended on what the dealer or owner fitted at the time.

You could always get a vintage grease gun but there’s no harm changing the nipples (zerks) as long as the type you buy doesn’t foul anything.

Makers like SKF will do these bearings but either knowing the bearing number or measurements will be what you need. Sadly I don’t have that information to hand, but try places like CBS, Ed V or any of the site sponsors.

Many bearings even branded makes are made in China these days so I wouldnt be too worried about the origin, just make sure they are a known make.

I dont know if you are going to use the old bearing seals and as an alternative try using a bearing with seals built in.

There;s a good UK supplier of bike bearings, see This Link

The poster is in Utah

I would advise against reuse of any dust seals. Any moisture, or metal filings from the olds bearings will be soaked in the felt. As this isn’t a question by the poster it’s probable that he already knows this.

1640 (7/8x2x9/16 inch) 2pc (equivalent to RLS7)

add 2rs for double SEALED or ZZ for SHIELDED,( i'd use sealed). to the part number.any bearing dealer can help very common numbers for alternators and such.i understand your trepidation on chinese bearings. in my opinion it might be not worrying about in this application. its not a perfect world to be sure. i replaced a shaft bearing that had failed in 2 roll chicago ironer some years ago. it was double sealed and made by FAFNIR a rather large bearing it had left the factory with NO grease at all.
