Welcome to the Beamers, Ian!

1. The oil gauges of different machines do not deliver the same absolute values. It is the individual relative one, which counts. When being cold the gauge will go to the stop. Only when the motor becomes warm it will give you a value (mine is at around 30 lbs/sq. inch) and only when reaching a stable value the motor is on running temperature. In fact, I use it as a temperature indicator.

2. Any mono grade oil is fine. I use Castrol XXL 40 and it is ok at 10 and 35°C (tested in the Alps). Grade 50 and 30 are also ok but then I would adapt them to the season. I have a grease lubricated gearbox (no oil). There is a dynamic crankshaft seal which stops oil floating from the sump into the primary case. Hence, I believe that one can use the same oil as for the motor. At least I do that.

Cheers, Thomas

Hi
Being new to the Sunbeam marque, I have several basic questions to start with.
The bike is currently being re-commissioned.
Work completed by previous owner - new piston/re bore - new valve guides springs valves

1/. Expected oil pressure at the oil pressure gauge
    Cold start and running
2/. Type of engine oil (make and grade)
    Type of gearbox oil (make and grade)
    Type of primary chain case oil (make and grade)

Thanks for your input.

Regards Ian R

My solution were additional shims on the outer side adapted to the correct position with respect to the valves. I don't know if this applies to your problem, though.

I'm been in touch with chris odlin
And end float when assembled need be 0.3mm on the rocker and bush play 0.5 to 0.3mm

you asked for photos of my rocker box bushes. Here are some of them seen from the inner and outer sides. I also attach a sketch from Chris Odling.

Thank you Thomas

It has been partialy restored, the transfer and the lining are orginal.

Thanks, Dani! And your tank has never been repaired, I suppose?

Hi Thomas
On my M9 the logo has a slightly different colour than the lining. I therefor suspect, the complete logo is a transfer sticker.

Dani

Hi all! Does anyone know if the logo on the tank was always a transfer or if it was hand painted in gold in the works like the lining?
Cheers, Thomas
