Yamaha Chassis

[mike4aera]

I have a Yamaha chassis, 77 or 78 I have been told. I am going to put a 4cycle predator motor on for my Grandson. Just started working it on today. Can you press out the bearings in the front hubs and replace them. The original bearings are made in Japan and they have a part number on them. Thanks

Probably better bearings than you are going to get together since most are made in china.

If you can read the number on the bearing it should be a good part number for a replacement. You can also press em out and measure the bore, width and OD. I get mine from carquest.

Are there kits available to rebuild the brake master cylinder on this Yamaha chassis?
I found the bearings for the front wheels.
Thanks

Post some pics of your master cylinder.
I've found it easier to just buy a new one over fixing the old one.
If there's any type of corrosion going on inside it's near impossible to repair. The aluminum is so corroded by the time you get the corrosion out and the bore cleaned,you removed enough of the bore the seals wont work.

I seem to recall there were 2 different sets of brake calipers and master cylinders used on the Yamaha RC100 racekarts, depending on it's year of manufacture.

Here's a link an active facebook Yamaha RC100 group (Vintage Yamaha Kart Fans) that could help you I.D. your karts era and brake componets, and probably hook you up with parts and lots more info you'll be needing: https://www.facebook.com/groups/257498411360347

I found a new/old stock brake master cylinder. Got the bearings for the rear axle and front hubs. Are there rear brake cables available for this kart.
