Hi there,
Been on the road now living 9 months in our 1984 CF280 motorhome in South Africa. Learned a lot about it and i need the wheel alignment done. Finally found a garage that have enough headway for the motorhome that is 2.8meters high to do the wheel alignment

The fellow say he needs the camber, caster and tow specs as he dont have it on his system

Would appreciate this info please
Greetings
Johan

John ...dont know if you still need the steering geometry , here is the info from the Haynes manual

Toe in 0.3/0.13 in 0.76/3.3mm

Camber 1 degree 11 mins to 2 degrees 11 mins
[to be within 0 mins 30 mins side for side]

steering pivot inclination 10 degrees 19 minutes to 11 degrees 19
mins

Castor angle 0 degrees 47 mins to 2 degrees 17 mins
[to be within 0 degrees 30 mins side for side]

toe out on turns [knuckle angle] outside 19 degrees from straight ahead
inside wheel at 20 degrees
hope this helps

1984 model could have the later specifications if it has straight steering arms (compared to earlier arms with bend at the end to clear 13-inch wheel rims).

All specifications to be sure because the change was during 1983 production year -

Front Wheel Alignment

Prior to Chassis No. CV604699 (right drive) and Chassis No. CV604608 (left drive): 1.8 - 6.1 mm (0.07 - 0.23 in.) toe in at wheel rims

From Chassis No. CV604699 (right drive) and Chassis No. CV604608 (left drive): 0 - 3.0 mm (0 - 0.12 in.) toe in at wheel rims

Camber Angle 0° 24' to 2° 24' - to be within 0° 30' side for side.

Steering Pivot Inclination 10° 25' to 11° 55'

Castor Angle 0° 30' to 2° 30' - to be within 0° 30' side for side.

Toe out on Turns (knuckle angle)

Prior to Chassis No. CV604699 (right drive) and Chassis No. CV604608 (left drive): Outside wheel 19° from straight ahead with inside wheel at 20°

From Chassis No. CV604699 (right drive) and Chassis No. CV604608 (left drive): Outside wheel 20° from straight ahead with inside wheel at 22°

Front Hub Bearing End Float 0.05 - 0.13 mm (0.002 - 0.005 in.)

For geometry checks the front hub bearing end float can be reduced to zero (nut hand tight using just a socket on the nut), to be adjusted correctly before the vehicle is used again.

Hi Phil, thanks for info. Where do i find the chassis number? The only plate i can find is on the passenger door side. a aluminum plate with lots of number with only this one meaning something EV600996. Hi Phil need to mention i have 14inch rims not 13inch

You found the SPI (Service Parts Identification) plate which also should have on it the rest of the chassis number as chassis series (e.g. 97360). Other codes refer to factory and SVOS (Special Version Option Scheme) options, useful to know when looking for some parts.

Anyway, EV is 1984 production year (Luton plant) so the later numbers for toe-in and toe-out on turns should apply. Sorted. :thumb:

Incidentally, the chassis number will have 14 characters of the form 973600EV600001 prefaced by SKF (the SKF manufacturer identifier and the extra 0 to conform with EU VIN requirements) and there should be a VIN plate attached to the fire wall (bulkhead) above the heater air intake under the bonnet.

Just one of many changes made during CF production ...
