Bolt Size for crank pulley

Featured Replies

I have a 91 Loyale EA82

 

Yesterday the crank pulley that runs the alternator & accessories v-belt loosened up and fell off (its the center pulley that connects to same shaft as both timing belts & flywheel).  I have the pulley and belt but I need to figure out the correct bolt size as the bolt got lost ( I know its a 22mm head but i don't know the length, width or thread size). I must have not gotten this bolt quite tight enough when i did the timing belts this summer.

 

Anybody know the bolt size/type?

Thanks!

BIG.

 

sorry, cannot help, but,  would it be easier for someone to post the proper crank pulley bolt out to you ? Sure I could if I was just a little closer ..

 M14 thread with 1,75 pitch. Flange head bolt, flange diameter is 38mm.  Under the flange, you have 12mm of unthreaded shank and 20mm of thread.

Torque to  66--79 ft/lbs.  If you use 'blue' threadlocker, torque to 66 ft/lbs.

Yep, thats the bolt, thanks silverback! 

that same thing happend to me a while back. driving down the highway and i hear a tink!" and im like well that was odd... and then the car started over heating. i ended up driving to a subaru graveyard and getting another.

You might want to double check the pitch.... looks like 1.5    ( as there are 10 threads in 15 mm).

If you need one i got an extra one floating around if you want it. Just pay for shipping. Let me know just pm me

Pitch is 1,75. I do not use a plastic scale for pitch measurements.

Old post I know but this thread came up in a Google search and was questioned by others discussing it on FB today.

I just checked the crank bolt thread pitch on the original EA82 engine out of my 87 DL and it is without a doubt a M14 x 1.5. I happen to have a metric tap of that size and it threads perfectly into the hole and lines up exact when laid alongside the bolt. I assume other EA82s will be the same.
