    As you can see, these data sheets were produced in 1991 and many things such as oils, fuel and even received wisdom have changed so BEWARE if you use them. For example I use a 115 main jet in the Solex 30MOV as newer fuels with ethanol caused spitting when using the 110 jet. I also use SAE 80/140 oil in the back axle contrary to the SAE 40 suggested here.

    The pages will change every 30 seconds; you can move forward or backward by using the arrows shown in the bottom right corner.

    This website contains my personal Maintenance schedule based on the late Micky Radford's "The Vintage Alvis Manual" and is supplemented by Lubrication charts from the Alvis TJ 12/50 Instruction Book. These notes are not intended as advice or guidance to the reader.
