Ace, Aceca & Greyhound Forum / Re: AC Ace steering box?

« on: October 16, 2022, 09:33:41 »

Greg,
This is from the UK M.O.T testing manual (annual vehicle check though many older cars exempt)-so 75mm for a 380mm diameter wheel.
You should be able to make a quick calculator in excel for different wheel diameters  or mark your wheel with tape at the 380mm dia/190mm radius.

To check steering play:

    Make sure the road wheels are on the ground and pointing straight ahead.

    Lightly turn the steering wheel left and right as far as possible without moving the road wheels.

    Check the amount of free play at the rim of the steering wheel.

If power steering is fitted, the engine must be running.

Steering wheel free play should not be more than:

    13mm for rack and pinion steering, or 48mm if there are several joints between the steering wheel and the rack
    75mm for non-rack and pinion

These limits are for a standard 380mm diameter steering wheel. The limits should be adjusted up or down accordingly with larger or smaller diameter steering wheels.

Play due to wear or maladjustment must not be confused with apparent play due to the construction of the mechanism, such as caused by the deflection of flexible joints or spring compression in external power steering systems.

Uwe,
I find it hard to see how the tie rods wear? The Track rod end  ball joints -yes I can figure that happening.
I noticed that Moss have a French office/base-they may have the parts you need.
Hopefully you have resolved  the issue.
Regards,
Graham

Greg,
One way to check if the play is due to  an issue in your linkages (ie track rods) or the steering box is to jack up one wheel and check for play at the wheel that's jacked up (the steering wheel ought not to move as the wheel on the ground has it locked) followed by the other wheel (with side you just checked on terra firma). Assuming no play you can assume its in the steering box.

To be consistent when comparing the steering wheel play test the steering wheel diameter needs stated as if you fitted a larger steering wheel the play ( although the same) will appear larger.

Toe in ( or out) is across the axle so for me all references are total.
I am sure the track ace measures total toe in/ out as it’s measuring one wheel relative to the other.( I have used a track ace since they came out).
Regardless of your tracking setting , the play in the box will dictate whether you control the car via the steering wheel or the road surface does the steering for you due to road surface changes and the play available to it.
I would Jack the car up and check ( with someone holding the steering wheel) how much slop you have at dead centre
My vintage 1929 Citroen had such an issue ( worm and sector) and it felt like I was driving a boat down the road.

Are you sure thats not the relay rather than the solenoid? My car (CRS) has the solenoid on the starter and the realays in the passenger footbox.

It ought to be on the starter so I would check there first.  If it’s not there then it could be remote so look in area near battery.

Laurent,
Good question -what type of rack is fitted and whats it from. Any clues (Part numbers , ford or other ID stampings on the rack you presumably have removed?
You could see if a specialist like this can refurbish it:
https://steering-racks.co.uk/

I just did a search for "steering"  on the MkIV thread  and came up with these-seems to be a modified MGB and Gerry Hawkridge  mentioned as a supplier:

Laurent-re the wheel bearing --the one in place should have a code number on it to get a replacement.
I found the adjustment article so will email.

Laurent,
The upper rose joints also set the caster/camber so either mark up carefully /measure (count turns) or follow the guide I wrote up in action a few years  back.
I may have the article in "word" somewhere buried in my pc if you want a copy.

I used Mcgill motorsport.

Mk IV, Superblower, CRS and other Continuation Cars Forum / Trigo 427 6 pin Alloys for sale with spinners and centre caps

« on: November 21, 2020, 11:07:22 »

New (not used on car)  Trigo 427 6 pin alloys, (4) wheel spinners (raw finish, 2LH,2RH)  and (4) centre caps (raw finish)

Wheels
3x 15 x9.5"
2x 15 x7.5"

Would sell one of the 15x9.5" separately.

In original Trigo shipping boxes

The fronts have been machined by Trigo to have the correct offset for  the Cobra or MKiV caliper, but need spacers(or hub spaced) for the CRS 6 pots calipers as its a close fit ( I have done a trial fit up) .

Wheels in Scotland but I may be able to arrange delivery from a friend who makes regular trips south.

I was informed that a small batch of these are currently available in the UK:

http://www.randbmotorsport.co.uk/shop/Details.asp?ProductID=386

I recently got 2 from the states at a comparable price.
If you are running an uprated clutch these make a difference over the plastic quadrant and are also manually adjustable.

David ,
I have sent you an email on engine mods, however on the Mk IV / CRS  Section people did do some air filter & spark plug mods to overcome some low output issues.
There’s no easy ,low cost solution due to what was installed and the UK mot regulations on emmissions.

I’m not sure what engines were installed in the Brooklands Aces or gearbox configuration but am surprised you have the 50oz external weight.

Constance,
I have been without a pc for a couple of weeks but up and running now.
The Grey car does have the inset rear lights-see attached.
