Am I the only person fella that finds the socket for the A series crank bolts too large?
Is there a smaller option available like a 17 or 19mm?
Ive changed a few seals that needed this monster socket but usually at a friends workshop
but would love to have a 19mm instead even my suzuki 1.6L takes a cheap wonderful 17mm.

Cant remember the thread size on the crank pulley bolt. its either 14mm or 16mm. Bolts suppliers will have options, even a sucket head cap screw if you want to go down that road. 8.8 high tensile at a mimimun should be used.

OK found it, 16 x 1.5 pitch. you may need one of these as well. •12308-H1000 WASHER-PULLEY BOLT

That is very helpful Benny!

The stock A-series crankshaft pulley bolt is:
Stock Part Number: 12309-78200 ($4.58)
M16 x 1.50 (fine) pitch
15mm diameter
27mm long
The head is 27mm hex and about 15 mm thick.
Torque: 15-16 kg/m (108-116 ft. lb.)

yeah a little bit too big. because L series use same 27mm.

Its sure to spins faster with a smaller head :)

Is the length right 27mm long?

Crank pulley bolt on my A12 measures at 27mm long

Thanks DD so the head is 27mm and so is the length of the threaded section? - Ive just rang a bolt and fastener joint and they only have 50mm thread length definitely dont want to cut it but then they only have 23mm hex head which is far from 19mm :{

General rule of thumb: As long as the thread engagement of the bolt into the crank = the diameter of the bolt, as a minimum [1.5 X bolt dia is better], you should be OK.

D, just go and fetch a cheap socket....
