Can't see why you would have such a thich washer at location 1 but certainly 2 and 3 would be how you adjust bumpsteer.

As far as I know, my care used to be un touched when I started working on it, so this I belive is std solution.

I haven´t check myself, maybe they use a std ball joint which don´t have enought threads?

Just took all mine to bits, it didn't have those but mine is a turbo and has he tapered hole for the toe rod fixing. My Spitfire toe rod came with a selection of bump steer washers/spacers for the outer joint.

So watching  another speedster this weekend, I noticed one difference. On the other speedster there was a pin screw (it looked like this) in the front bearing assy with a nut instead of the drive shaft as you have in the rear.

My front bearings were just empty.

Is it needed to have something there?

What should I place there if needed?

It's apparently to make sure the bearings in the hub are properly clamped. NA's had them but turbos didn't.

[Arno]

Yup..

 

Lotus fitted these bolts on early cars. Later cars did not get them. They carried these over from the S1 Elise which did require these as these cars use tapered roller bearings that require the clamping force to stay in 1 piece.

 

On the Speedster and S2 Elise they are not a strong requirement as the original bearing type used on these cars (double-row angular contact ball-bearing) is self-contained and can not 'fall apart', but for cars that get tracked a lot it can provide better support for the bearing to withstand the side-loading it experiences and reduce wear on the outer races and play developing.

 

So it's more of a 'nice to have' upgrade than a real requirement.

 

Bye, Arno.

Thank you Arno for a good description. I tried to studdy the section cut linked on Elise parts homepage for the wheel hub. And I can not see how this could help to have the bearing pre loaded. Br, Per

[Aerodynamic]

So something is going on still. Since I got a lot of help from you guys I´ve been able to put the rear suspension back together.

I started with the rear, so when I lift in the engine I can assembly the drive shaft directl o be sure they fit.

After

 

I´ve also waited for some parts for my engine, a chain guide

and a new haevy camgear.

 

 

So today I´m going to continu working on my engine again.

Are you going to remove the VTC (ECU controlled cam timing adjustment) system from the K24 with fixed cam gears? Can I ask why?

 

It's a very useful feature of the engine to get the best and most even torque at both low revs and high revs as valve timing overlap requirements change so the ECU can adjust.

 

You're turning The K24 into an 'old skool' H22 engine with VTEC only this way?

 

I know some racers do this, but they often run with VTEC-killer cams and remove the VTEC as well so the engine always runs on the 'high' lobe at all times (and needs to idle at 1500rpm or so...) as they want to reduce the weight and complexity in the cylinder head. But it has big tradeoffs for lower rpm's..

Be cool Arno, he simple answer is no.

The VTC is on the intake side, this is a exhaust cam gear. And I don´t know why this new cam gears look like this. But I have looked at different K serie engine from early on to late models and the story repeats itself, "performance" engines are using the thicker cam gear and the sneak egnines are suing the thinner camgear, but I don´t know why.

Some should say because the thicker is stronger, but if you look at it and thick about it, the stronger cam gear are oversized and it would rather break the cam.

I belive the weight is in some was a flywheel shock absorber.

Why can´t you edit your answers?

 

Engine is comming along slowly. Had to wait another week for a bolt holding one chain guide.

 

 

But what valve is this?

 

The coolant "can" I remember I red somwhere the same one is used in another Opel,

does anyone know which one? I need a new one.

 

BR, Per

 

[techieboy]

Vacuum line one way valve to the brake servo.

[vocky]

coolant tank is from an astra G

[Aerodynamic]

Thanks both.

[Arno]

 

Be cool Arno, he simple answer is no.

 

 

Ah! Sorry.. The picture was of the same exhaust cam gear, just the old and new one..

 

I thought it was a photo of a replacement intake AND exhaust cam gear and got confused

 

Bye, Arno.

[Aerodynamic]

I see, I never wrote it was a new and old exhaust cam gear.

[Aerodynamic]

A small update, Right now I´m working on a porch for the house so not much happening with my engine.

But today I recived this. 

New intake giving some extra ponys and making the hoosing a bit easier.

 

Also, I accidently sold my ECU with my engine, as I though the ECU was in the car and then someone said it was on my motor.

So anyone have any idea about the ABS system, is this separated from the ECU? or do I need to have the original ECU to make it work?

 

BR, Per

[vocky]

abs works independent from the engine ecu

 

ps: my webcon ecu does not communicate to the abs ecu

Good, I really want to keep the ABS and later on upgrade it to a lotus 4 channel.

 

Anyone know where to find Wiring diagram a component location chart for the VX?
