4. Fit the cases into the frame to make sure that they clear the motor mounts. Check
motor mount alignment and shim if necessary. Install voltage regulator and check
clearance to motor mount rib. The next thing to check is the clearance between skid
plate (if so equipped) and the crankcase inspection plate. It may require the use of
spacers on the front motors mounts. We also suggest drilling a hole in the skid plate for
the oil drain plug to facilitate easy access.
5. Assemble lower end as per service manual.
7. Once the lower end is assembled, torque case bolts to 18-22 ft. lbs. except the top
case bolt (1/4-20), torque it to 10 ft. lbs.
Caution: for larger than 3 5/8 bore cylinders torque the 1/4-20 bolt to 96 inch pounds.
Be sure to use a medium/serviceable grade threadlocker such as Locktite blue (242)
8. At this point it is advisable to check connecting rods to the case decks for proper wrist
pin alignment. Don’t assume the rods are straight.
9. Breather and cam timing can now be checked using the Delkron Space n Time tool
(sold separately); with our Space n Time kit you can also check your cam and breather
end play as well as timing!
10. Finish final assembly as per service manual and install engine.
11. All cases that have a serial number that starts with DLK now have an “O” Ring seal
on the bottom inspection cover. Place the “O” Ring on the inspection cover first then
install the cover onto the case making sure that the drain plug faces the back of the
engine. It is not necessary to use sealant on the Inspection plate but if you wish to that
would only reinforce the integrity of the seal.
WARNING: If using other than OEM oil screen plug insure that thread length does not
exceed .300 inch or blockage of the oil passage to the lifter blocks will result in damage
to the lifters.
NOTE: All threads in DELKRON products are standard thread, oil pump screws are ¼ x
20.
Caution: Make sure that the timing plug clears the inner primary before final assembly.
WARNING: Some powder coating processes utilize excessive temperatures and can
damage the case. Any powder coating not performed by Delkron will void the
warranty.
