YAMAHA Yamalube Yamabond 4 3 oz.

I discovered Yamabond when I was a Yamaha tech in the 90's. It's all I use from then to now. It blows every other RTV out of the water, both in sealing and cleanup. If you ever have to open something up sealed with Yamabond, you can clean it off with a shop rag. It will ball up and roll off. No need to get out the razor blades and chisels and gouge the sealing surfaces. Bonus points for NEVER curing in the tube. Nothing worse than thinking you have sealant at midnight just to learn you have a hardened tube that solidified. With this stuff you get ever drop. Even if it takes a year to use it. It and Yamabond5 (and 6B now) are all I use. Cost more money but they flat out work.

I was rebuilding a robin 2pg engine and had to split the lower case to change crankshaft bearings. This stuff seals good for those jobs that don't use a paper gasket but needs a liquid gasket. The stuff only dries where the air isn't present. A very thin layer in my case still squished out inside and out. I actually had to take it all back apart again to adjust bearing shims and applied less during the final installation. Seeing it squish out just a little bit though verifies you have enough between the mating surfaces.

Great product and customer service. Product arrived on time. Can't go wrong when using correctly with Yamabond. Beats Permatex any day. Great for Scooter center crankcase housing along with motorcycles and etc

Absolutely recommending this product to anyone who’s interested. I’ve used other products and this YAMALUBE is by far the BEST.

I’ve been using Yama Bond for over 50 years now. I was glad to see Amazon was carrying a great product.
