Space was too limited and I was concerned about getting a good sealing face. Initially I planned on running an A-Series housing with an adaptor plate but didn't much like that. There have been several iterations in this area during the build. This put a real downer on the build for a few weeks.Įventually I rediscovered my mojo and pushed the rest of the kitchen into service getting the box back togetherĪs shown in the image above there is not a lot of room between the back of the cylinder head and the heater, certainly nothing like the space needed to run the Nissan thermostat housing. Sadly I was just given the "we've never had any trouble before" response and wasn't even offered re-reimbursement for return postage. Another nice feature was the tabs of material waiting to fall off into the gearbox.Įven the shims supplied didn't fit and had to opened up to fit on the mainshaft. It had also been dented and bruised in several places and was missing the spot faces. It was supplied covered in swarf and grit that had got into the seal itself. Worse was the replacement front casting with a lip seal conversion. The "Heavy Duty" layshaft, while hardened, was ,002" undersize on diameter compared to the original making it completely useless I had heard horror stories about some of the cheaper suppliers / parts so decided with cough up and go to a reputable supplier, despite the cost being twice that of the competitors. Unfortunately this is where the trouble began. I was impressed with the condition with only a few minor parts in need of replacement. M6 stainless studding being put through it's paces!Įverything was then cleaned up and measured. Some of these guys went ping and have never been seen or heard from since. The book of lies was reasonably useful but I used heat rather than a big hammer to remove the bearings. The strip down was pretty simple and satisfying. With the gearbox on the bench I figured it was probably sensible to pull it apart and make sure all was well, seeing as it was completely untested. Sorry if that was dull, I figured it may help someone at some point in the future. If I do have trouble with this arrangement I will put a stop in and return the start point to the original position. The clutch appears to have bled fine so the ports must still be working in the M/C. The pedal sits marginally lower but isn't very noticeable and travel is reduced to a safe 16mm. I have adjusted the end stop in the pedal box rather than fit a pedal stop. Measuring the piston travel in the pedal box there was 21mm travel. When compared to the 7/8" master cylinder's 388mm2 area there is a ratio of 0.62:1 so the maximum safe master cylinder travel is 16mm. This unit has a 32.5mm ID and 43mm OD with a safe travel of around 10mm. With it all in pieces I was able to measure the diameters and work out the maximum safe piston travel. This piston pushes the plastic carrier and thrust bearing with the entire assembly kept together with the big spring. The tube seals to the body with a square section O ring and the piston slides along it, sealing on both the tube and body. The assembly is held together by a press fitted ring in the end of the tube. This would confirm how it actually works and allow me to confirm whether a pedal stop is required. I had made the mistake of taking a best guess at the setup as I hadn't looked hard enough for information about how these slave cylinders work.Ī bit of digging brought up this document which was pretty helpful: With the engine out of the car again I figured it would also help to strip down the cylinder. Because I had converted to a concentric slave this meant the engine had to come out. I had cocked up the build height and the slave cylinder had come apart. So after getting the engine running I hit a problem when bleeding the clutch. Obviously manifolds will be different but I don't see it being a serious problem. I have been able to confirm that with the same modifications made to the sump as I have done on for the Midget the CG will fit a Morris. Moggyman - I hope that is the case, it's a big market. I want it to be competitive with a the cost of having an A-Series rebuilt (properly) to standard specification. Merryck - I am working on costs at the moment.
