8 Doweled Crank and Flywheels

We 8-dowel all cranks to the "SPG" pattern. and use the longer 8mm dowels
order
This is the Standard Pattern for all VW cranks.

Please note that one dowel is not evenly spaced.
This insures the flywheel is always mounted in the same relation to the crank. (This is necessary when the crank and flywheel are balanced as an assembly.)

The four extra dowels will have a tight fit and for this reason the End Play must be set with only the original stock four dowels.

If the stock 8mm dowels are loose you can use the 11/32" dowels to save the crank & flywheel. order

Factory recommended end play is .003/.005 with 3 shims installed.
shims

All three shims must be in place before installing seal. 

After every thing is set and checked, Only then are the new four dowels installed.
order

Note: It may be necessary to use a flywheel puller to remove the flywheel once all (8) dowels are installed.

Be Sure to clean all dowel holes, Gland Nut threads and all Oil passages before installing the crank. 

12volt Flywheels use an "O" ring and the metal gasket.
order

The Paper gasket was used on the 40hp and 1300cc motors. 
order

Many builders use the "O" ring and paper gaskets instead of the metal 12v gasket. 

We recommend using a HD Chromoly Gland Nut on all Non Stock Motors. HD-Gland Nut-->
*ck  order

Be sure to check the gland nut in the crank before installing the flywheel.
We have found some Gland Nuts to bottom out or the dia. to be tight in some cranks.

Check that all dowels are lower then the flywheel surface before installing the gland nut.

Be sure to follow the torque figures supplied with you new Gland Nut.
order

We recommend using Loctite on the four stock dowels as they most likely will be a little loose.

We also Loctite the Gland Nut as an extra precaution.
