Starter Motor sticks when engine is hot

Looking for some help locating a new starter motor for my '88 Cabbie. It has the 1.8 engine with an automatic box. Neither Heritage nor Classic VW have the starter in stock. Does anyone know of other suppliers out there? Appreciate any help.

You need to be careful as there were two starters, one for a narrow flywheel starter ring, and the other with a wider ring. If you fit the wrong one you will chew up everything.
If you can get me the number off your existing starter, I do know a brilliant place where I have an account, and I can at least ask them to check if there is one they can get in. Would probably need the car reg.
 

The flywheels are spoked, and solid.  Requires different starters.  But you probably need the heat soak rely installed.  See www.cabby-info.com transmission then the diy's.  I will tell you I got stranded 250 miles from home on a trip.  If it weren't for me having an extension cord I'd still be there.  Knowing where the starter solenoid pick wire is  red wire over the tranny to rear of engine there is a white molex connector Jam a wire there, key on in park the touch it to the positive battery and if your starter spins you are good to go.   Sorry this reply on phone as I am away from real puter   

You probably don't need a starter but a 40amp relay and a couple butt to but connectors and a couple of pads female.  It is a tsb from about the mid 80's.

If I ever get on a puter, I will post a pic of it.  I used a Ford starter relay from the 60's  f100 truck.

Ok,

Heat soak fix.

When I installed mine I placed it behind the Airbox on my 92, and 93.

Solenoid Pick wire. The only one you have to cut, the Firewall side goes to the heat soak relay pick.

Wire that goes behind the engine goes to the Starter solenoid direct to the big lugs. The other big lug goes to the Battery B+ positive side.  The Ford starter relay gets its ground from the screw bolting it to the frame.



Spoked flywheel actually called flexplate.
From under the car you can see the flex plate spokes or solid plate.

Timing plates
Spoked at the rear solid at the front.


Starter motors are different.
A solid flexplate will work on a spoked, but it will chew it up eventually.
A Spoked starter will usually work on a solid flex plate.

The Solid Flex plate starter will have no bump outs in the middle of the Circled areas.  

The Spoked starter will have bumpouts.




Now they made a "universal one" that could go either way,

Now for the rest of the story.
My 92 was driven out of state by my daughter, I would occasionally have a no-start hot or cold issue, and I replaced my Starter with a genuine new Bosch starter for a 93 spoked flex plate.

So the car, wouldn't start 450 miles away.  My Daughter took it to a shop who said the starter was bad, and they replaced it.  (the starter was known good and less than 3 week old.

She never told me about this out of state adventure as I would of taken the car away from her.

So speed forward about 6 months and she was starting the car, and I heard it grind.  it started and she drove off.

One day the starter would spin and spin, but the engine never turned over.  

Jsck the car rotated the wheels and watched the flexplate and saw thid big chew.


Looked up at the starter and it wasn't the one I put in.
It was a reman.  I pulled it down, and there weren't any bumps.  I took it to my local guy to look up the part number and it said pre- mid 1990 Solid plate flex plate.

So they hung the wrong starter, which chewed up my flex.  So I dropped the tranny, removed teh flex plate and
welded up the teeth and  filed them down..why because you couldn't buy a new flex. This worked fine and in about 6 months of scouring the local Breakers I finally found a solix flex plate.  Spoked ones are hard to find…

I did make the out of state place refund the monies for thoir error and I pocketed it, when my daughter said it was her monies.  I reminded her that if she hadn't taken the car out of State with me knowing about it. I would give her,  her money back.  Since they removed a 250 dollar good starter, and replaced it with a 79 dollar starter, the monies was mine.  

It took me about 6 months to locate a solid plate.  
I was thankful as about 2 weeks later my welds got ground down.

Moral of the Story was me finding a work around for my no-start warm or cold issue.

I had the same issue, I took the starter motor out and dropped it with a guy who reconditioned it.

….. and then I did the heat soak relay modification.
