Starter bolts

[Bukowski]

'87 944 na

What type/size bolts hold the starter on? 19mm hex and Allen? I want to get the right tools before going in there.

Thanks, Happy New Year!

No washers on my starter...just 2 19MM bolts and of course the 13mm bolt that holds the wiring in place.

2 19mm bolts with washers hold the starter to bellhousing, a 13mm nut and an 8?mm nut hold the wiring

Hi,

the heads have 19 mm Hex and 10 mm Allen. For the electrical connection you need a 10 (maybe 8) and 13 mm Hex. For the 19 mm you need a special bar, even a breaker bar is too thick.

In this video you'll see the dismounting of the starter in all detail:

The video has a German soundtrack, but English subtitles are added to YouTube. If you don't see them by default, watch the video directly at YouTube and press the subtitle button below the video.

I've probably taken 10 or so 944 starters off and have never used anything but my normal ratchet and a 19mm socket, and a 13mm and 8mm for the electrical connections. You shouldn't need any special tools.

I agree with Corey. And I don't even have the 8mm connection...

Hi,

watch the video at 1:07 and you'll see the problem. You don't need a special tool, but a small bar for driving the 19 mm socket, because a standard 1/2'' ratchet is to thick to access the bolt.

The subject of the video is the tool P233 for locking the crankshaft, but it shows also the dismounting of the starter, because the P233 tool is installed instead of the starter.

Best regards,

Jürgen

He makes a good point, I might not have the right size bar to make the clearance.

19mm box end wrench with a second wrench on the open end for torque were all I ever used.

[Bukowski]

so does this mean US cars different from e.g. Germany cars in this regard?

what are the torque values for the mounting bolts?

[Bukowski]

here's my update:

my starter has both bolts that secure the starter to the bell housing as hexheads, using a 19mm socket. that means there's no allen style bolt. I suppose it is easy to swap different bolts in there. My electric connections have 8mm, 13mm and probably 13mm though there is a lot of corrosion - consistent with what other people said.

The bolt facing the front of the car - i.e. the one with very little clearance, in fact has little clearance. from what I can see, a crescent wrench or a boxend etc. has too much meat on it to rotate into the area between the bell housing and the starter. A socket - which typically has a thin wall compared to a crescent or box end wrench - fits nicely all around the bolt.

The next problem is the area where the socket would have a socket wrench attached. indeed there is not enough room. I found that a 3/8-inch drive universal joint will angle outwards enough to give plenty of rotation.

so my answer for the rear bolt is to use a 3/8-inch drive 19mm shallow socket attached to perhaps a short extension and then finally a 3/8-inch drive socket. It is not clear to me how a 1/2-inch drive anything will fit back there - I estimate 3.5-4.0cm of room - but perhaps a trip to the hardware store will help.

An inaccurate estimate of the torque was around 28 Nm. This is using the aforementioned wrench setup, so it is not adjusted for the angle of the universal joint.

ANOTHER UPDATE:

forgot to try my 3/8" breaker bar, about 8 inches long - guess what, it gives about 30 degrees of rotation with a shallow socket. there's a Craftsman 10", and HF has a 17" bar. HTH!

can you specify the make of the wrench?

I am hearing that e.g. Snap-On has thinner walls than others (I have a Craftsman, it seems thick).

Cheap Chinese crap, I inherited from my dad. Short story, he was pretty PO'd when everything went metric and wouldn't buy high quality metric tools, after spending decent money on standard tools for 40 years. I think it's a great neck wrench, but I have no idea if its still the same company that autozone or advance (forget which one) gets their tools from. It's from the early 80's. My craftsman wrench set stops at 18mm and I've not been inclined to buy a new wrench for the starter bolts. Sorry, really no help here.

My car is an early, not sure if laters are a tighter fit or not.

Ok, what model years?

What make of socket/wrench?

[nightheart]

If you can fit a socket on the bolt, but not enough room for a ratchet, would something like this work?

You could probably get a craftsman or better version of the same thing.

[nightheart]

Alternatively you could look at cheaper tools. The Chinese wrenches probably have more clearance around the boxed end, just do to being cheaper metal and less beefiness. It's unlikely you'd brake a 19mm cheap wrench under these limited torque requirements.

Interesting, thanks!
