 Post subject: quick rack
PostPosted: Tue Dec 26, 2006 5:25 pm 
I am after a quick rack for the dolly.
Can you buy these anywhere.
If not am i right in thinking that you can swap the pinion with one out of a Herald or Spit to make your own.

Cheers Neil

As far I know the diferance is the number of teeth on the pinion.
Original it has 6, and the quick one has 7, aprox 17%.
Actualy if you have a good not worn out rack, only swap the pinion, and ofcours adjust the play with the shims.
I have good results with a slichtly stonger spring, or shim the spring with a thick washer.
Finding the corect shims to adjust is best done without the spring first.

The 7 th. pinion is a standard part for some Dolomite related model, I have heard Toledo, 1300 Fwd but can't tell for sure.
I cheked all my steering rack's and found 3 quick pinions, just enoufh for the 2 cars race cars and a spare rack.

I now have an 1850, Sprint and 1300 dolly rack. which one will be hiding what I'm after? I'm so sure I've read Sprints have quicker ratio racks than the rest....

Just bought an exchange one from rimmers. 3.25 turns lock to lock compared to my sprint one which is 3.75 turns lock to lock (or thereabouts.

Mine had really excessive wear on one side (like 3mm play!) so I needed a new one anyway.

I'll probably get stung when I send in my standard one for the surcharge rebate!

What really hacks me off though is the recond quick rack has a total length that is at least 1 inch longer than my original. How can that be. Also they have painted the threads on the tie rod bars so I cannot get the locking nuts on. Pathetic

I phoned Jigsaw up last week £250 ish for a quick rack. Didn't realise that that rimmers did one although I'm not sure that i'd want one from there anyway.

I should have thought one from jigsaw uses at least some new bits, rather than just being a painted toledo rack...

Fitted and tested my Rimmers one. Apart from having to lob off 1/2 inch from each tie rod as the overall length was 1 inch longer than my original I am very pleased with the new rack. Also changed to solid mounts, solid lower steering UJ and new track rod ends. Car was aligned as well.

Car is, as you would expect, very tight, very sensitive to steering input (which was a vast improvement on the worn out rack I changed) and does turn in which better. Overhaul a great improvement with excellent feedback through the wheel. Only downside would perhaps be the pot hole feedback direct to my hands but that goes with the solid mounts I suppose.

I just got a reply from Rimmers and they claimed their Quick Rack is 2.6 turns l2l. Is this correct/possible?

Also... Can someone explain to me how the pinion with the extra tooth 'magically' meshes with the rack? I can't figure this one out...

I believe all pre '74 Dollies had a 'quick rack'. I also understand that the only difference is the pinion & yes it does 'magically' mesh with the rack.

Regards.

I concur.
The 1972 Dolomite (1850) specification (as listed in the brochure) confirms this and the parts catalogue lists a different number for the pinion.

Also, I am fairly sure early Sprints had the "quick rack" from new.
