Crankcase<br />
All <strong>Engines</strong><br />
Crankcase halves are factory matched and therefore,<br />
are not interchangeable or available as single<br />
halves.<br />
<strong>717</strong> and 787 RFI <strong>Engines</strong><br />
Rotary valve shaft must be installed in crankcase<br />
before closing halves.<br />
CAUTION: Before joining crankcase halves,<br />
make sure that crankshaft gear is well engaged<br />
with rotary valve shaft gear.<br />
<strong>717</strong> <strong>Engines</strong><br />
Temporarily install armature plate to align<br />
crankcase halves with each other.<br />
CAUTION: Using different types of oil may reduce<br />
engine component life.<br />
All Models<br />
IMPORTANT: When beginning the application of<br />
the crankcase sealant, the assembly and the first<br />
torquing should be done within 10 minutes. It is<br />
suggested to have all you need on hand to save<br />
time.<br />
NOTE: It is recommended to apply this specific<br />
sealant as described here to get an uniform application<br />
without lumps. If you do not use the roller<br />
method, you may use your finger to uniformly distribute<br />
the sealant (unlike the Drei Bond sealing<br />
compound, using a finger will not affect the adhesion).<br />
Use the silicone-based Loctite 5910 (P/N 293 800<br />
081) on mating surfaces.<br />
NOTE: The sealant curing time is similar to the<br />
Loctite 518 without using the Primer N.<br />
CAUTION: Do not use Loctite 515 or 518 to seal<br />
crankcase. Do not use Loctite Primer N with<br />
the Loctite 5910. Using these products or non<br />
silicone-based sealant over a previously sealed<br />
crankcase with Loctite 5910 will lead to poor<br />
adhesion and possibly a leaking crankcase.<br />
These products are chemically incompatibles.<br />
Even after cleaning, the Loctite 5910 would<br />
leave incompatible microscopic particles.<br />
Use a plexiglass plate and apply some sealant on<br />
it. Use a soft rubber roller (50 - 75 mm (2 - 3 in))<br />
(available in arts products suppliers for printmaking)<br />
and roll the sealant to get a thin uniform coat<br />
on the plate (spread as necessary). When ready,<br />
apply the sealant on crankcase mating surfaces.<br />
