REAR BUMPER GUARD INSTALLATION -lark MOdels W,F,J and Y Body TypesChanges in rear bumper installation pro-

cedures in product ion necessitate a change inthe procedure required to install the RearBumper Guards, Part No. AC-2941, on the Larkmodels.

We suggest the following installation pro-cedu re:

1. Remove the bumper 1'ace bar, inner bars andrear gravel shield as an assembly by removingthe 4 inner bar-to-1'rame bol t s , nuts and washers.

2. Install the two bumper guards on thebumper and shield assembly.

3. Reinstall the entire assembly on the carwith the 4 inner bar-to-1'rame bolts, nuts andwashers.

REAR QUARTER WINDOW RATTLELark Hardtop MOdelsThis will supplement information in service

Bulletin Number 345, dated March, 1959.

Excess clearance between the rear quarterwindow weatherseals and the glass 1'rame willcause quarter window rattles.

If excess clearance exists at this area, itmay be caused by the rear quarter trim retainerflange not being hooked over the rear quarterinner panel.

If excess clearance still exists with therear quarter trim retainer properly positioned,the clearance should be reduced by followingthe procedures outl ined in step 4, Page 2 01'Service Bullet in Number ;345.

Mo" 3~9 S E R V ICEROOF PANEL REINFORCING BRACELark Station Wagon Models

In some instances a rattle or drumming typeor noise may occur in the area of the roofpanel on station Wagon MOdels. Investigationshows that this noise is a result of clearancebetween one or more of the three roof panel re-inforcing braces and the roof panel permittingthe braces to vibrate and strike the panel.

The braces can easily be located by feel ingalong the headlining. The reinforcing bracesare equally spaced between the rear of the dooropening and the rear tail gate opening.

A sheet metal screw at the end of each braceis used to attach the brace to a bracket thatis welded to the roof 1 ine area just above theouter edge of the headl ining. Extra holes areprovided in the ends of eaCh brace and in thewelded-on bracket. When you encounter thecondition described above, It can be correctedby the following procedure:

1. Remove one of the side window garnish mould-ings in the brace area and pull down the head-1 ining to expose the brace and bracket.

2. Remove the sheet metal screw, and with anawl inserted through the brace and bracketholes, pry up the brace tightly against theroof panel.

3. Insert the metal screw through a set ofholes that will hold the brace tightly upagainst the roof panel.

4. Reinstall the headlining side section andthe side window garnish moulding.

GASOLINE TANK FILLING 1969~odels - Body Types W,F,J and Y

This will supplement the information giveno~ Page 1 of Service Bulletin No. 347, datedMay 1959.

A gasoline tank change entered production onthe 1959 Lark models with Serial Numbers595-94294 and 59V~35661.

The change consisted of a new gasol ine tankupper stamping (upper half of tank) whichlocates the filler pipe at the highest pointunder any reasonable level conditions.

Gas tank spacers mentioned in the article inService 8ulletin No. 347 are not used with thenew tank after the above serial numbers andshould not be used in service on cars afterthese numbers.

CLUTCH OPERATING SHAFT BRACKET -Lark Left Hand Control W,F,J andD ModelsThere have been isolated reports of the

clutCh operating shaft on the 59S Lark modelsjumping out of the shaft retaining bracketsocket.

Inspection of the replaced assembly revealedthat the spring or wobble plate was soft and con-sequent distort ion and permanent set which hadtaken place could have reduced the amount ofsocket engagement considerably.

Where a condition of socket disengagement isencountered, check the plate for distortion. Ifdistort ion is found replace the assembly. Theassembly part number is 1547737. When install ingthe new assembly, be sure that it is positionedto obtain maximum socket engagement.

WATER TEMPERATURE INDICATOR,ENGINE UNIT - 59S ModelsTo provide a more satisfactory temperature

reading a recalibrated engine sending unitentered production with Engine Serial No.S-94083. Th is un itis part number 1549452 andcarries an identification '362-AR' stamped onone face of the hex head.

The new engine unit should be used as a ser-vice replacement on all 59S models.

Servicing procedures for the Bendix PowerSteering on the VB Hawk Models are the same asthe procedures outl ined in the 1959 ShOp Manualfor the 1959 Lark Models.

SELF-LOCKING STEERING WHEELNUT - AI I 1959 MOdelsA newly designed self-locking steering wheel-

to-post nut was used on late production 1959models.

The following procedure should be used wheninstall ing the steering wheel:

1. Check to make certain the steering postjacket is properly positioned on the steeringgear housing top cover to prevent possibleinterference between the steering post jacket

and the steering wheel hub.

2. Align the mark on the top of the steeringwheel with the mark on the end of the steeringpost and install the wheelan the splines.

3. Install the self-locking nut and tighten thenut to 25 to 27 foot l b s torque. It is veryimportant that the nut be tightened to thesespecifications. The recommended torque mustnot be exceeded.

SHORTER FRONT COIL SPRING - 59SW,F,J and 0 MOdelsA new shorter front coil spring, Part No.

15~7373 entered production with Serial Number59S-739~ 7.

The new spring carries the front of the carapproximately 1/2" lower than the previousspring. The new spring has an approximate freelength of 17-5/32" and is identified by a daubof green paint on the coils.

Because of the difference in carryingheight, both the spring used before the aboveserial number and the new spring will becarried in stock. The shorter springs areinterchangeable with the longer springs butmust be replaced in pairs.

CORRECT POSITIONING OF POWERSTEERING HOSES - 1959 Lark VBModels with Bendix PowerStee r In gWe have received reports of power steering

hoses coming in contact with the exhaust mani-fold and steering gear. Investigation revealsthat in most cases the hoses were improperly,positioned, twiited and not properly secured.

The following information and illustrationsestablish the correct positioning and securingof the power steering hoses.

Figure 2, an underneath view of the 1eft-hand side of the car, illustrates the positionof the power steering control valve-to-cylinderhoses and their retaining clamp. Note that theretaining clamp should be approximately at aright angle to the center 1 ine of the car, alsothat the hoses parallel one another as well asthe frame.

This illustrat ion reproduces,as closely as possible, the relative positio-ning of these units and hose assembl ies intheir installed positions: The pro~ectivegrommet on the power steering pump-to-controlvalve hoses should be located approximately 7"from the lower end of the hoses.· This isnecessary to prevent any scuffing of the hosesby the steering gear housing. The spring wireand sleeve assembly must be wrapped around thetwo pump-to-control valve hoses approximately3" above the protective grommet, with both endsof the spring secured to the retainer c1 i p
