        Chris,

        As you make reference to “the  fancy  tools  shown in the manual” I assume you do have a copy of said tome.  (If not it can be downloded from the technical pages).

        The book shows 2 methods.  The first (plate 24 in the drawings section) does indeed require some (relatively) sophisticated equipment but the second – plate 24a – is aimed at those who do not have that apparatus readily available.

         

        You will see it does require the manufacture of three simple blocks and recommends using a surface plate.   Any competent machine shop will be able to manufacture these blocks from the fully dimensioned drawing given.  I had a set made some thirty years ago, and in addition to the numerous times I have used them myself, they have since been borrowed by a number of other owners as they cost little to post (within the UK).  I would be most surprised if nobody in NZ has already made a set which they would be prepared to lend/hire to you.

        However, if you do need to have a set made locally I am sure the cost which will not break the bank – and then you can hire them out!

        Prior to obtaining a wonderful surface plate from a garage that was closing down, I always used a good quality mirror for the flat surface but a piece of float glass will be equally serviceable – the thicker the better to minimise distortion under the weight of the clutch components.

        I hope this helps.

          Thanks  Bernie . Sound  advice  and  I will  enquire  from the local  scene  – someone  might  have a set of “blocks”  Cheers  Chris

            I was keen to have ago at toggle adjustment but the advice line said I would be better off taking it to a clutch specialist.  I have a 1955 11C with 4 cyclinder performa engine, the cluch friction plate and flywheel has been rectified, and reassembled with fresh springs, spacer washers, toggle bolts washers and nuts. Is there any specific information I need to give to the clutch centre or will they just know what to set it at?  Thanks regards Alain

              A reputable organisation is likely to be fully genned-up but I would suggest you offer them a copy of the relevant info from tbe manual.

                Hi Chris  from New Zealand  replying  A few of  us  have  done it this  way . Bolt the  pressure  plate to  the  flywheel  using a 11 m  spacer plate   then  set the  toggle levers  according to the  diagram .It  worked for me

                  Thank you Chris and Bernie. I am starting to reassemble but have a question. When the flywheel was removed I noted it was secured in place with 6 15mm bolts no lock plate or lock washers to be seen. The parts manual has a lock plate in the pictures, is this required for the reassembly in this 1955 ID 19-P?

                  Thanks.

                    Alain,

                    Do you know anybody with an original spare parts catalogue?  Unfortunately, I do not have the spares book but I do have a manual for the ID.  See operation 41 in the relevant page from the ID workshop manual ………

                    This clearly says no “lock washers” and does not mention a plate.

                    I must admit I am surprised because the “11D” Traction engines definitely had a one piece “amoeba” locking plate for those screws.

                    Personally, I think I would want to fit one on an engine destined for a Light 15 – it can surely do no harm and could save a lot of long-term grief.

                    B….

                      Thank you Bernie, I have obtained a lock plate but it sits proud of the fly wheel as the crank is not recessed. I might need to cut a bearing size hole in the middle. Your phot was helpful as it specifies torquing it to 36 lb which is almost double that in my 1938 to 1950 12/15 repair manual. It is possible with these later tractions that it was set to 36 lb.

                        Alain,

                        Proud?   How much? Is it simply held off by the bearing?

                        I need to check but, if memory serves me correctly, the locking plate is formed to allow the bearing to protrude a couple of mm from the flywheel and the plate then also serves to retain the bearing.  Cutting a “bearing size” hole would defeat that object.

                        B….
