early af18 stator and pickup interchange?

[eliteguy50]

Will the '87 stator fit the early af18?

[veedubh20]

same like 87 crank. must use 87 driveface/ramplate/boss/14mm nut/12mm pin
will fits early af18 block only!

yes 87 stator must use af18 mag

Sanjuru seems to be pretty well informed on these engines.

The right side engine carter for the af18 motor is the same as the 87 elite se50. The pickup is the same too.

So everything on the right half of the af18 is the same? Doesn't matter if it is big or small crank?

[sanjuro]

Yep, that's right. It's the left side engine carter that has the smaller diameter oil seal for the smaller crank on early af18 motors.

I'll check my spec sheet when I get home to verify.

[sanjuro]

Ok, got home and looked up the part numbers and specs.

Oil Seals for AF18 and AF16
91201-GK8-003 (15.6X25.5X7) stator side oil seal
91202-GAH-721 (19.4X31X7) variator side oil seal

The early small crankcase Dio AF18 motor used the (15.6X25.5X7) oil seal on BOTH sides. That's why you have to use a different spec variator for the early Dio motor (1st year for the AF27 and AF28, and used on the Dio SP gen bikes).

Hope that clears it up.
