Steering Questions

Recommended Posts

Been fitting the new standard Westfield steering rack on Mr Toad to replace the old slooowww Escort rack. I have two questions.

 

First question.

It looks like the original builder of the car has used M8 bolts to attach the universal joints to the steering rack and to the steering column. These should have an unthreaded shoulder to fit in the grooves on the rack and column splined spindles, but they don't. I'll be replacing them when the bolt stockist near me opens on Monday. Should they be M8, or 5/16th UNF? 5/16" is 7.938mm, so it shouldn't make any difference? Measuring it up it looks like I need an unthreaded shoulder length of between 15 and 20mm.

 

Second question.

I've set the tracking roughly so it can be driven slowly to somewhere where it can be set properly. Is, for example 1/2 degree toe in 1/2 degree per wheel, or 1/2 degree across both wheels? See diagrams below.

Thanks,  Jenny

1/2 a deg per wheel Jen.       I did the 2.4 rack change a couple of months ago, one of the best upgrades I've ever done,  adjusted my toe with a drive over plastic guage.  Worth buying one if you're always changing things on the front of the car.

Jen, the one with a shoulder is called a bolt. The one which is threaded the full length is called a setscrew. My help when you go shopping.

 

Are you going to the supplier behind the gasometers (turn left of Penistone Road)

Hi SootySport,

Thanks for setting that straight for me. I'm planning to make up a wooden gauge to help me set the toe in with a bit of aluminium screwed on to act as a fixed surface I can measure the gap to the wheel with the vernier caliper each side from that. Looking forward to trying out the new steering. The old steering has always seemed slow compared with other Westfields I've driven. OK, a couple of those were factory drift cars, so probably not a fair comparison as they would be lethal on the road with my driving skills.

 

Hi Norman,

I'll probably go to Williams Fasteners first. Much closer to me. What's the name of the supplier by the gasometers?

Pretty sure my bolt is 5/16 UNC. Maybe best to get one of each

Jen, I can't remember now. A friend ran it but he died from a heart attack 5 years ago. 

 

OK, HM has just remembered - Permafast. It seems to be a different company now HERE. Probably none of the original staff there now anyway.

 

Anyway, Williams will have it. On Caterhams they're 5/16 UNF bolts. I would fit flat washers each side and a Nyloc nut.

Hi Norman,

Sorry about your friend. I'll go for 5/16 UNF with nylocs and plain washers. I've found several odd decisions the original builder took when assembling Mr Toad over the years. Slowly getting the car how I want it. Only taken six years so far!
