Rocket Three oil return
« on: February 09, 2019, 12:25:56 PM »
I am currently rebuilding my Featherbed framed Rocket Three.

I never did like the way the original builder made the oil return into the tank and want to alter it so the flow of oil can be seen and is above the oil high level point.

Iím assuming that in order to create back pressure so the rocker feed gets an acceptable amount of oil that the exit hole of the return pipe is smaller than the 7/16Ē bore of the hose. Does anyone agree and if so can anyone tell me the diameter of the hole or size of tube in the original oil tank.

Usually the end of the return pipe is flattened leaving a slit for the returning oil. No idea what the corss section would be however.

Don't know about a Rocket Three tank but common or garden BSA's and Trumpets I've had had a small hole 2-3mm in diameter in the top of the oil return pipe. Just enough to check the oil return to the tank.

Thanks for the replies.

Thatís what Iím basing my assumptions on and would have made it the same size as my oil in frame Bonnie but the Rocket Three feed and return pipes are bigger. I also have to take into account the Rocket Three has its oil cooler after the rocker feed take off which will create some back pressure. I sure Iím thinking too much into it but would like to have a definitive answer.

Hi
I think your question would be better answered on one of these forum

Iíve looked at both forums occasionally but I cant get on with them. Thereís too much going on on the iPad screen, if a wayward bit of hand brushes the wrong part of the screen you could find youíve married someone from Latvia, male or female! Not that thereís anything wrong with Latvians, male or female. Itís just that the current Mrs Grunt might not be best pleased.

I think Iíll join the Trident and Rocket Three owners club.
