WXA99 has the oil reservoir for the jacking system but the system was removed at some point. I am interested in learning as much as I can about the system and hunting down parts to put it back to right. I will send pictures of what I have in a couple of weeks, but any info handy that can be shared easily is appreciated in the meantime. Thank you. |

Jack, (you have an appropriate name, here), the D.W.S. Permanent Hydraulic Jacking System was part of original chassis-equipment. As a result of that, it is mentioned and explained in the handbook. WXA99 would need handbook XVIII (=18). Do you have that very number? In the early thirties the company Smith (supplier automotive equipment for car manufacturers), had in its range the "Jackall"-system. Look at the car standing on its jacks:
For reasons of reliability (presumably), RR did NOT install this system. Instead, approx 1933 onwards, RR did install permanent mechanical (scissor) jacks made by D.W.S (Donald Wilfred Sessions) - to PII, 20/25 and 25/30. Later, the same manufacturer DWS provided permanent hydraulic jacks for PIII and Wraith. Searching the www, you will not find much about the hydraulic DWS system (ONLY used by RR, as far as I know), but "Jackall" (=a similar system but with wider use) may reveal more info. The full hydraulic system is rather complex : The pump, (with handle), the oil reservoir and the four bottle jacks are made by DWS. All other equipment (brackets, oil pipes, pipe junctions, supports, stone guards, etc, etc...) are of RR-manufacture. The only parts available are some rubber sealing joints. This being said, it is very nice you have the intention to bring your car back to its former glory. But, I'm afraid it may prove to be very difficult (impossible?) to source missing parts. For a carburettor (etc) things are clear, people do keep (and sell) these. A bottle jack, a jack pump,... what the hell is this kind of part ?? It is not a vital part. People do not recognise, do not offer, throw away... Good luck! Koen, |

Thank you, Koen. I am also looking for a handbook…I appreciate you letting me know that #18 is my match. Unfortunately, no literature came with my car, and I have found some difficulty with the online archives. I appreciate all the information you provided. When I get back to the car, I will report back with a more detailed assessment of what is missing and what survived. It may be futile, but if there is a way to recreate the system, I would enjoy that. Thank you for the great information! |
