This is why I ws asking, being tapered rollers, if they are not torque, what's right and what's wrong. Too loose will cause failure, too tight will create friction heat and badness.. I'll phone them for a definitive answer

experimenting with ideas for front side panels I have never been very keen on the steering rack linkage sticking out of the drivers side so we had the idea of making the side panels in 2 parts the front part fitting just within the chassis frame ( more brackets needed) but this would have the advantage that it would then cover the whole steering linkage: We would then make a second panel at the back which would be flush with the inside of the chassis we are planning to put some holes or a grill in this to help air flow out from behind the radiator Can anyone see a problem with this before i satrt making panels and brackets ??

I know that the steering rod sticking out the side of the panel Isn't ideal but it also allows more air flow onto the radiator, admittedly Not a great amount but it does help with the cooling.

Are you sure ? i would worry that the stream of air over the side panels would reduce the pressure and suck air out of the linkage hole from the space in front of the radiator so more air that is rammed in from the front grill would escape out of the hole and bypass the radiator ??

It's difficult to say which way the airflow would travel as the rockets exoskeleton design will causes havoc with the it. Generally speaking the area infront should be designed to have a higher static pressure to increase dwell time for better cooling and the curved shape of the side walls should accel the airflow around the outside of the car thus lowering the static pressure. I.e making the air flow from inside to outside the car. Not that it matters as the gap between the panelsand steering rack will be so small as to have no real effect on cooling.
I don't see any problems with your design accept that it is very difficult to make the panels look neat with a flush

* fit. I have only seen one car with the panels mounted that way and they used a sealant to hide the gaps between the panels and the chassis tubes. if u r confident u can do it neatly then go for it. there are covers u can buy from rtr that nicely hide the rack, they were made by Scott and his old man.

You are right that doing it neatly is going to be key and I'm not sure we are really up to it the plan is to try making a nice rounded edge to the panel then use some adjustable brackets (with red anodised screws as a feature), to make it a neat fit probably with a uniform gap between sheet and frame of 5mm or so. We'll get the panels powder coated later probably metalic silver look. If we can't get it neat we'll use the premade covers. Cheers Jon

Hello. With regard to bearings, you will need to establish whether they are the preloaded type with shims or a deforming spacer. Generally wheel bearings with two taper single rows are adjusted in the following manner. Using a socket and wrench tighten bearings just enough so that they seat properly and the wheel rotates freely. Slacken nut a small amount so as not to disturb bearings, then hand tighten again without wrench. Back off one flat or to the nearest hole then insert split pin. Test for free play and wheel rotation, a very small amount of play will be felt. It is generally considered over tight bearings fail before ones with clearance. Here is an interesting link to SKF Bearings. www.skf.com/group/products/bearings-units-housings/roller-bearings/tapered-...

I think you will find that the covers were designed by the "Old Man" otherwise known as Grandad. Scott was just the apprentice!

Check out tony's cbrocket build, you'll see the cover late on in the build diary. Wayne.
