DRL152K Marina based roadster rebuild

[martinclan56]

So a bit of investigation and much discussion later resuted in pulling the engine to investigate the clutch issue. I had used a NOS clutch cover, plate and bearing, but to be on the safe side I have now purchased a new boxed set of the 3 components. The clutch plate and cover are completely different in appearance to the NOS items but probably similar in function. The bearing however is a different story. The bearing I originally installed, supposedly the correct item, was 16mm high. The new bearing is 19mm high. I have since put everything back together and refitted the engine and am pleased to say I now have a clutch that works!

Engine installation now complete and I have a working clutch. It's a long story but the main problem was the release bearing which was the wrong size.

Yesterday was a big milestone as I turned the engine over on the starter for the first time and established that I have good oil pressure. Always a fearful moment particularly as the engine hasn't been used for many years (20+) even though it had been rebuilt.

I have also now fitted all the ancilliaries and all the cables and pipes. Even with a simple engine like this there is a lot of plumbing.... The next step is to double check the timing, rig up a temporary fuel supply and fire it up. What could possibly go wrong....

A few pictures of the completed engine install.

Traditional SU HS4 carbs. Still thinking about how to add an air fiter as there is very limited space between the front carband the bonnet. Home made heat shield to hopefully aleviate fuel evaporation.

Accuspark distributor (Chinese hmmmm) and tiny Denso alternator. HT leads need a bit of tidying up and I am probably going to fit some right angle plug caps.

Completed exhaust system. I had the section with the flexi, which joins the manifold to the silencer, made from a drawing. Always a tricky thing to do with a 3 dimensional object like an exhaust. But it fitted after a little fettling. It looks a bit low but at the current chassis height there is about 5 inches of ground clearance - the same as the sump.
