camber adjustment

[hawk gt 62 rhd]

Good evening every studelover,I lost one of the upper control arm outerbushings.
No damage I think,I found anew one,but now camber adjustment!!
How is this done,I cannot find it in the sm,just the figures of torque and degrees.
May be this standard knowledge but I don't have this one in the brain,so I am asking for the real procedure,thanks.

You do not indicate the year of vehicle, but my Lark camber adjustment is done by removing the grease fitting from the outer bushing of the upper control arm and turning the outer pin. The pin has lobes, like a camshaft that can adjust the camber. Don't go to a tire store, I'll bet only a "real" alignment pro knows how to adjust this.

There may be a problem with the upper control arm because with the bushing screwed all the way flush with the "A" arm and torqued to over 100 FT Lbs the pre-load is from the bushing to the arm to allow the shaft to turn for the Caster and Camber adjustment. The instructions ARE in the the front suspension section for turning the eccentric several turns for Caster and a half turn for the full range of Camber adjustment. If the hole in the arm is good and tight, there is no way you could lose a bushing!

The upper inner pin itself has a camber adjustment. The bolt holes are offset from the pin centerline, so removing the two bolts and rotating the upper cross pin 180-degrees changes the camber.

However, it is difficult to tell whether this is will take the adjustment where it needs to go. Look at the top of the tire and the inner pin. Determine where it is installed at present, which way you need to move the top of the tire and whether flipping the inner pin will move the tire in or out. The offset with the pin to the outside of the centerline moves the top of the tire out. The offset with the inner pin toward the inside of the centerline moves the top of the tire inward.

"Where a proper camber setting cannot be obtained by turning the upper control arm outer pin, additional camber change is made possible by turning over the upper control arm inner shaft. (The holes in the inner shaft are drilled off the centerline of the shaft and turning the shaft over will increase or decrease the camber by aproximately 1-1/4 degrees.)"

thnx, jack vines

Please note that Jack is talking about the INNER upper "A" arm SHAFT! And it does have 2 ways to install it.

Hi, Rich,

Thanks for the suggestion. Check the edit. Should be clear now:

Jack and Rich thanks for your answers.My car is gt Hawk 1962 RHD no PS
I am plannig the following
1 adjust toe in ideal =5.5 mm minnimal=4.75
2 adjust caster iideal-0dg.30' max +0dg.15'
3 adjust camber LW ideal 0dg.30' minimal 0dg RW +1dg minimal+ 0dg.30'
4 adjust toe in again.

Another thing is:toe-in in the manual is 3/16 to 1/4, no PS ,it says 1.87 mm to 2.50 mm.but 1/4 is equal to 6.3 mm where is this going wrong?
I think it's a little misthinking ,not miscaculated.I hope you'll agree with my figures and I am looking forward to your answers,regards lmwaterreus

No one mentioned it here but did you spread your control arm when you reinstalled the missing bushing?

[hawk gt 62 rhd]

No I did'nt, don't think it needs to when you torque these bushings to 100 lbs,I admit it is a bit gambling,but the figure in the workshop is much too high for these bushings I think

[leyrret]

When installing outer metal bushing in the control arm you must have the control arm spread I believe .015" while tightening the bushings.
When released after tightening will give operating clearance in threads of pin. It kind of jams everything up if you don't.

Hello Leyrett,now I am getting a total view in this matter maybe my last concern is,whitch Allen key do I need int he caster and camber procedure, I cannot tryout because I have none in inches only metrics.

[leyrret]

I'm not sure. I believe it's 1/4" but I'll have to check to be sure. Maybe someone else knows offhand.

[leyrret]

I checked. It is 1/4 inch. If you get a socket make sure it's long enough..

[hawk gt 62 rhd]

Thanks Leyrett,I 'll buy one tomorrow.

Hi Leyrett ,it isnot over yet,this afternoon Iwas at the alignement shop and we discovered that there were noholes in the upper outer pins not in the front not int he backside,maybe the are the wrong ones,
My car is assembled in South Africa this thind could be gone wrong there ;it is an early 1962.
I think I tap some thread inboth sides and use a glued Allen secure pin to make it possible to turn the pins ,in order to adjust them for caster and camber.
there is a slight possibility that my partsshop has the wright ones with the Allen holes,but last time I did not see them.
Btw there is a little cone formed pit in the ends of the pins I cannot see the use of them,regards Dick Waterreus
