Starter Motor problems

[Rubce]

Hi All

Hit a snag. When trying to start the engine today the starter motor is making a high pitched whining noise followed by grating sound. Sounds as if the motor is not engaging with the flywheel properly.

On a couple of other occasions it tried and failed to turn the engine. I popped it into 2nd gear and rocked the car which seemed to stop this particular affliction.

Is it a starter out, clean teeth job? After all the hassle in fitting it the thought having to take it back out again fills me with dread

Regards

No suggestions?

Hi Bruce

I have had this problem but I can not remember what the cause was, is the battery top notch?

Make sure all connections are clean and tight.

Hi Stu

The battery was new in Jan 2008. The red stag subsequently failed its MOT in May 2008 so the battery has only done about 500 miles and then stood for 2 years until yesterday. I'll put the trickle charger on it overnight and see if that makes any difference.

Plus I will take your advice and double check all the connections. All the cabling is brand new and the only old items are the three terminals on the starter itself.

Cheers

The solenoid should pull the teeth into engagement before it switches the power on, sounds like a problem with the actuating linkage. Check the nut on the pivot is tight as I think the shaftis a type of cam which can be used for setting the depth of engagement of the teeth.

I hada similar problem when I first fitted the stag engine to the TR. I actually cut a hole in the inner wing so I could get the starter out (Otherwise engine out job to remove) and it turned out the nut had come loose and the shaft had to be turned and then locked into position

Hi Neil

Thanks for your thoughts. I have converted the car from auto to manual. This involved changing the flywheel. Was I supposed to adjust the cam setting on the solenoid as part of the conversion process?

Hi Bruce

Yes this was the problem I had, I put a manual starter motor on a Auto and the solenoid did not throw the cog far enough to catch.

Hi All

I think I have really screwed up during the assembly of my carAs you will see from the thread above the starter motor was making a screaming noise and sounded like it was not engaging.

So this evening I removed the starter to investigate. I took a measurement from theengine side of the engine adaptor plate where the starter mounts to theengine side of the flywheel. The distance was 26mm.

I then measured the distance from the flange on the starter to the furthest the pinion gear can extend to. This was approximately 27mm.

This means that with the starter mounted in position and the pinion gear at full extension it will only have 1mm of overlap/gear engagement with the flywheel. Obviously not enough!:shock:

When I looked at the starter the pinion teeth had a nice shiney band of approx 10mm from when it used to be fitted to the auto. This seems a reasonable level engagement with the flywheel, unlike the 1mm I have now.

The part no. on the side is Lucas 25648 which according to the Rimmers catalogue is a later type Stag starter motor

So, my questions are as follows:-

a) were there originallydifferent types of starter fitted to auto and manual gearboxes? Perhaps the one for a manual has a longer front extension?

b)when I look at Paddocks and EJ Wards websites they only list one type of starter. Is a modern aftermarket starter of a design suitable forboth auto and manual with longer extension than the one I possess?

c) perhaps I have assembled the engine adaptor plate and flywheel incorrectly to the engine resulting in the flywheel being too far away? I am going to post a series of photos that I took whilst assembling the adpator plate, flywheel to the engine. Perhaps one of you more experienced individuals will spot something I have done incorrectly.

Please help:?. The thought of having to take the engine, gearbox, flywheel, clutch, exhaust, radiator etc all back apart again fills me with dread:shock:

Thanks

here is the first photo showing the bare engine before fitment of adaptor plate or flywheel.

second photo showing engine adaptor plate now fitted. Can't see how I could muck this up as it locates on dowels.

third photo showing flywheel fitted. Don't see how I could fit the flywheel the wrong way round as it has dowels on the non engine side for the clutch pressure plate to locate onto.

Please note that I left the spacer positioned on the end of the crank. Its clearly visible in the previous two photos. Was this correct?

The starter motors are the same for auto and manual.

I am sure I did not replace the spacers when I converted to manual and a quick look at the parts manual indicates they are only used on the auto. Looks like that is your problem. Sorry.

Having had another look at the Rimmers catalogue I see what you mean. BUG**R. How the heck did I miss that when I reassembled it:X.

Thanks

[img]file:///C:/DOCUME%7E1/alan/LOCALS%7E1/Temp/moz-screenshot.png[/img]i concur no spacers required on manual
flywheel connects to crankshaft flange by six bollts and a dowell
no spacers
spacers washers even on an auto go on torque converter side
as in picture
