seth Posted March 11, 2007 Share Posted March 11, 2007 Help!I've been busy with a couple of mates today swapping the dead 1500 and 3 rail box in our Herald for a fresher 1500 and single rail/OD box. As it was getting dark we were finally ready to try and fire it up and the starter motor just jammed everything solid.On the old 1500 I had used a 1300 flywheel and small clutch. To suit the new single rail box the "new" engine has the normal larger 1500 flywheel and clutch. However I opted to re-fit the original inertia starter motor (for ease of wiring) Does anyone know if this won't mesh properly with the 1500 flywheel and that I have to use the pre-engaged one? The ienrtia starter worked fine on the engine we removed.It got too dark to compare the various bits and it'll be a day or so before I can have a proper look so I just thought i'd try the communal knowledge pool! :) Link to comment Share on other sites More sharing options...
Smallfry Posted March 11, 2007 Share Posted March 11, 2007 The inertia and pre engaged ring gears are different. The pre engaged type has a finer pitch ............smaller teeth, or more teeth on the flywheel if you like ! Obviously the gear on the appropriate starter matched it.Theoretically, they should not mesh at all, but probably make a nice grunching noise, but if components are worn they might jam ?

seth Posted March 12, 2007 Author Share Posted March 12, 2007 Many thanks smallfry. Having taken a look at the two starter motors this morning I can see the obvious size difference in gear/teeth. It had just got too late and I was too tired to try and sort it out last night! So I'm obviously going to have to put the pre-engaged starter in. Can anyone identify the A and B terminals in the photo for me? I have a Dolly wiring diagram and the battery cable/brown feed wires obviously go to the large one at the top. One of the small ones should be white/red from the ign switch and the other is White/Yellow feed to the coil.*But which is which? I've never had a car with a pre-engaged starter before ;)(* I realise this is the 12V starting feed bypassing the ballast resistor and won't be using it anyway....)

seth Posted March 12, 2007 Author Share Posted March 12, 2007 Never mind, I had an hour free this afternoon and figured it by the trial and error method. I tried the wire on A first and had no joy. Put it on B and it worked! :) Turned the engine over with the coil lead off to get some oil pressure, reconnected the lead and it fired right up. Looks like Katie will be mobile again tomorrow ;D Link to comment Share on other sites More sharing options...
