Build Day 11 – DeDion tube, drive shafts, and oil pan assembly

I didn’t have a whole lot of time today so set about getting the rear suspension started. As I was starting the radius arms and Watts links Kim came down and snapped a picture of me. Having the TV hooked up to the computer is both good and bad – I can blow up diagrams and instructions if I need to, but also distract myself with Band of Brothers streamed from Amazon Prime fairly regularly.


Since Kim was around, I switched off to the drive shafts and De-Dion tube. I climbed underneath the car and had her pass the DeDion to me from the right side. I also wrapped the chassis tubes with some rags to protect the paint; good thing I did. Then inserted the drive shafts; right and left sides.

The drive shafts slotted in with no trouble, but noticed a 5mm or so gap between what I thought was the seal and the shaft. This seemed odd to me so gave it a wallop with the rubber mallet a couple times. They didn’t budge and seemed like they were in ok. Off to the computer to research other build blogs.

Having solved the drive shaft mystery (yes, its normal for a gap to be there based on the other build blogs) I went ahead and started on the oil pan.

The oil pan is interesting. First of all, it’s a Raceline oil pan made for Caterham that’s thick and heavy enough to withstand a nuclear blast. Second, there’s no instructions on how to assemble it. Thankfully, Dave had put together a good overview on his blog and the steps to do so are pretty straight forward. In the event his blog ever disappears, I’m recreating the step-by-step here with some pictures.

  1. Two rubber O-rings on the L shaped pipe. You’ll know which two they are.
  2. Two rubber O-rings on the little metal O ring. Again, you’ll know which two they are.

  3. Add screws and spacers to the baffle plate. Secure with nyloc nuts. I torqued until tight then a little bit extra.Baffle plate assembled
  4. Screw the L shaped pipe into the bottom of the pan in the center with some red loctite. There’s only one screw that fits so this is straight forward. Put the plastic clip down over the pipe, again there’s only one way it fits.L tube into pan with plastic spacer
  5. Put the mesh filter in through the hole in the side and secure with the blue cap. Note the metal O-ring and the rubber O-ring.Mesh and blue cap
  6. Put the hose attachment in on the 45 degree hole in the side. I secured mine with a bit of teflon tape. Torque until tight… then a little bit.
  7. Lastly, attach the dozen or so screws to the top with some red loctite. Torque until tight… then a bit more.
  8. The cheese wedge piece of metal gets screwed to the engine oil pickup with the rubber O-ring situated in the grooved ring. Use a little grease to hold it tight.
  9. The metal O-ring with the two rubber O-rings attached gets added to the indent in the oil pan. Use some grease to hold it steady. Note, we attached our oil pan from the bottom up rather than the top down to keep things sitting where they should be and not having to risk that O-ring not sitting right.

With the oil pan loosely assembled I called it quits for the day. I got where I needed to and was pressed for time anyway.
