Hello All,
I am new to the site but have owned a 1968+2 (chassis No 50/0604), for a couple of years. It is a rolling upgrade, Never ending adventure! With a current MOT.
The car has been running for some of the time owned, but i have recently hit the following problem that i cannot find how to resolve. I hope that the vast experience of the List will be able to point me in the right direction.
I started with the car in running order, found that the distributor was loose, and took it out to check the condition of the unit. (I did not advance the engine to TDC, thinking that there would be no problem in turning the engine over to TDC to set the static timing, when i replaced the distributor.
Distributor cleaned and checked (Lucas 23D4) I decided to turn the engine over to TDC on the startor motor. Starter Jams and will not move.
Following removal of the starter (previously working) I found the teeth of the engaging wheel badly chewed. Flywheel checked and no apparant damage.
The starter is a different type from the one noted in the Workshop manual. It is a LUCAS unit with the number 25147 stamped on the side, with a highlighted number 123, and a highlghted 4 painted in silver just below the front face.
The workshop manual notes it should be a LUCAS M35G.
As the starter had previously worked without trouble, I exchanged it with a refurbished unit of the same type and number, from my local Motor Factors.
While waiting for the exchange starter i tried turning the engine to TDC by pushing in gear, this was not successful and the engine would only revolve a few degrees before no further movement was obtained.
I fitted the exchange starter, which appears to fit correctly, however the starter when activated does not turn the engine over.i initially suspected the Solenoid, but the starter works perfectly via the solenoid when operated outside the engine.
I have cleaned and reconnected the block earthing strap with no improvement.
I have had the starter out and refitted a few times, in both of the 180 degree opposite positions that it will mount in, wothout any improvement.
The inertia mechanism, where the pinion is drawn back up a shaft from the opposite side of the flywheel from the starter body, after its initial movement returns it of the large end spring, is not a type i have worked with before, i have tried holding the pinion drive close to the top of motor shaft, near the body of the starter, in the drive position to see if it is meshing properly (difficult to determine) put it appears to be.
I note that the pinion has ten teeth, (i did not check how many chewed teeth were on the motor I exchanged) I remember some time ago discussion regarding the correct number of teeth being either nine or ten, depending on the year and the model.
When the starter is activated, full power is getting to the motor, and there is no crunching sound (that i have always associated with teeth not meshing on other types of engines) Simply the single clunk from the Starter.
One additional piece of info is the inability to turn the engine over by way of the bolt on the end of the crankshaft, even with all plugs and thre distributor removed. the engine is still filled with oil to the correct level, and was working prior to the start of this escapade two weeks ago.
This has been a long explanation but here are the questions that i hope you can help with.
-
Is the starter moter the correct one?
-
Is there a change over date for 9 to 10 teeth or vice versa?
-
is there any reason that ht eengine would have siezed?
Any help, thoughts or wisdom would be greatly appreciated. ( And would save my sanity)
Thanks
