Silver Spur, Mulsanne, and Comiche motor cars. These changes have been implemented at various times and are detailed as follows. Sikr Spirit. Silver Spur, and Mulsanne. (incruding Tub) from vehicle identification number licSCAZSOOOSBCH02290*. A fibre gasket is fined bslyeen the front road spring cover plate and the valance tower.]

6 Fibre washers are also fitted to the spring cover securing bolts and are located between the cover plate and the steel washer beneath the bolt head. Sitver Spirit and Mulsanne (other than f urbo) from vehicle identification number *SCAZS0004 BCH036948and Silver Spur from SSCAZN42 AXBCX03 7 1 7 Sincluding SSCAZNOOOOBCH034251i: SSCAZN0002 BCH03653S *SCAZN00088CH03656+ $SCAZN42A9 BCX0366? * $SCAZN0003 BCH03662* SCAZN42A2 BCX03 6639 A new horizontally located front engine mount is fined. This mount is of a voided cylindrical rubber construction having reduced stiffness and 1s fined in conjunction with a new crossmember. The engine forward stop plate previously fitted is deleted. New rear engine mounrs are fined which although of the same physical shape as those previously fitted. use sofret rubber. These mounts can be ~dentified by the part number which is moulded into the rubbet. An engine steady bar is fined at the front of the engine and is anached to a stabilizer arm which is secured by the two engine crossmember bolts.

7 The steady arm is secured to the engine through two shouldered rubber bushes and to the smbilizer arm through a voided cylindrical rubber bush. A reshaped bottom radiator hose is fitted to obtain clearance with the steady bar and stabilizer arm. Funher changes include the fining of tie-bars to the reat of the front sub-frame. adjacent to the rear engine mounts. To enable the tiebars to be fined, the front subframe is modified to include additional mounting brackets. Additional mounting brackets are also welded to the underside of the body congeron. Due to the fitting of the rear tie-bars the , transmission cooler pipes are repositioned These pipes are redesigned rc allow fitment to the inner side of me body longemn. adjacent to the tie-bars, and are then muted and clipped on the underside of the longeron fonnrard of the tiebars. as on cars prior to the mwii frption. The foHowing information is not applicable to cars fitted with perrd injection engines.

8 Two small hydraulic dampers are fitted to the rear of the engine. The upper end of each damper is located in a bracket which is part of a new transmission adapter plate. The lower end of each damper is located in a mounting bracket secured to the sub-frame by rhe two foremost setscrews which secure zhe rear engine mount bracket On cars fined with petrol injection engines the two smail hydraulic dampers are located at the top by a slotted bracket The bracket is fitted bewen the transmission adapter plate and the rear engine mourn and secured by the two rear engine mount bolts. The lower end of each damper is located by a bracket attached to the sub-frame by the two rear setscrews which secure the rear engine mount brackets. These dampers were fitred to cars fmm the following vehicle identification numbers.

The front subframe mounts. although of similar appearance to the original mounts. are produced from TSD 0400 a lower rated rubber. The new mounts can be identified by the part number moulded into tlqe rubber. A mm ( in) spacer is used in conjunction with the new mounts. The inner end of the her triangle levers are redesigned to allow shouldered rubber pivot bushes and distance pieces to be inserted. fhe levers pivot on bolts which also secure the levers to the rear of the subframe and to a new mounting bmcket at the front fhe new front mounring bracket provides shim adjustment to ensure that preload L not applied W the pivot bushes.

10 A steel distance piece is fmed between the front subframe and each stabilizer bearing suppon bracket. to ensure sufficient clearance is obtained between the stabilizer link and the link support bracket securing bolts. On some cars however. the distance pieces have been omitted. On rhese cars sufficie~ clearance is obtainable without their use. On left-hand drive cars from vehicle identification number Silver Spirit and Mulsanne-X-SCAZS42 ASBCX03698* and Silver Spur %CA2 N42 AXBCX037 1 7rl: including 4 SCAZN42A98CX0366 1s SCAZN42 AZBCX036633itfie twcr hydraulic pipes from the distribution mtves to the front subframe have been changed To allow the connection of the rwo flexible hoses to be made on the outside of rhe body longeron. A new hose mounting bracket is also used. WORKSHOP MANUAL Section HT H1 -1 Introduction As a result of continuous development and modification to the rtde and handling characteristics of the vartous models produced, changes- have taken place to the subframes and suspension.
