Pinion Orientation---

<< < (2/2)

hotater:
See if this works----

This is oriented as it would be in the engine--- threads stick through the crank-case...the first ground surface locates the spud in the crank-case in a counterbore. The ground surface before the 'head' has the pinion gear rotating on it. The spud is stationary. It bottoms out on the shoulder and leaves about .005 'slop' for the gear to freely rotate.
In this position oil flung into the top of the crankcase by the dipper runs into the milled slot and is fed into the gear bore to lubricate it.

Joe:
Hotater…I used the scientific paper clip method. My pinion opinion is that the slot on my engine is at 7 o’clock.  I couldn’t get the camera in at a suitable angle to capture a good shot.
Hmmm…does it make a difference? Unless there is something else compelling I would opt to go with 12 o’clock and let gravity help a little more.

Someone, somewhere has had to have scanned the technical drawings of these...even the Indians work off of detailed prints..don't they?

hotater:
In some places the definition of "Precision" is,  'Measure with a micrometer, mark it with chalk, and cut it with an axe'.

You found just what I did....I'll bet when that pinion was installed no thought is given to where the oil comes from.

The simple fix is to release the nut locker tab, loosen the pinion nut and rotate the pinion so the oil can run into the joint and retighten.  Don't forget to lock that nut!

I have no idea if it REALLY makes a difference, but to give an engine the best chance at reliability it has to be lubricated well.  Small details are sometimes VERY important.  One example is the 'funnels' at the mouths of the oil holes in the top of the rod big end.  You can bet the bearings would run dry-er  if the center-drill 'funnels' were left off, but it would be so easy for a bean counter to decide it was an extra and unneccesary step.

(The factory notice of defect in Howa Mach.Tool- made Weatherby Vanguard rifles was caused by just such a bean counter decision.  It cost a guy his right arm to find find why one milling operation left out was NOT a money saving idea.)
