Engine & mysterious parts (day 4)

Monday evening.
I gathered up some of the mysterious parts and sent a picture to Randy (the Caterham dealer) to help me identify.
Hindsight: Clockwise starting from top right – Diff top cover (not used), Gear shaft bearing that mates the engine to gearbox,throttle linkage, rubber boot to block unused plenum vacuum outlet, temp sensor to install at coolant outlet, 2 seals for the oil cooler plumbing, bracket for throttle linkage.

I worked on a few small things that I knew how to do and didn’t take long.. Fitted the following parts:

The challenging job was fitting the new sump. The main trouble was figuring out where everything goes without any manual. I started working on this on Sunday evening, but I ripped an O-ring and had to buy a new one.

After putting on the new O-ring on the collector pipe, I was really careful not to over-push it in – I used a piece of 7/8″ dowel as a stop.

There is a wire mesh filter that you need to install through the plug hole.

I found where the final little plastic part went.

Then fitted the Baffle plate.

Then, I put RTV sealant all around the mating surface of the block and installed the new sump & bolted in place. I put plenty of grease on the mating double-O-ring washer to ensure it did not drop off or move as I mated the two halves – if this part does not go right, then no oil pressure!
