flywheel index & pilot bearing alignment
« on: March 13, 2009, 01:34:39 PM »
Fixing my 96 4wd trackers clutch.  Bad pilot bearing (lost all its innerds) and lost a spring in the clutch disc.  Marked the flywheel to reinstall at the same position as per the shop book, but the shop that machined the flywheel cleaned the mark off.  How critical is orintation (index) of of the flywheel to the crank?  If it is critical how do I figure that out?

Popping out the remnate of the old pilot bearing with a socket was simple.  The shop manual says to use special tool Jxxx, to install the new bearing.  What are others doing to install it?

Thanks

I would think if your flywheel is balanced (I would asume it is)It shouldnt matter as for the pilot bushing I just removed & installed one with a socket and a hammer
If I have to understand don't bother explaining

Since the Tracker does not have timing marks on the edge of the flywheel like the Samurai, I would not worry about any indexing of the flywheel if there is no factory indexing.  If you look at one or both sides of the flywheel, you'll notice holes drilled part-way into it's surface on unfinished locations.  These were drilled during the balancing process.  That said, it should not matter how you bolt up the flywheel - it will be balanced.

You should be able to gently tap the pilot bearing into place with a dead-blow hammer and a socket that is a tiny-bit smaller than the pilot bearing as Spitfire Rick suggests .  If you are unfamiliar with this type of hammer, they usually have a wood handle and a rolled-leather head or is made of orange-colored plastic with loose sand encased in the head.


I hope that this helps!

Thanks for the info  :)

I was concerned about having the pilot bearing skewed in the flywheel.  I will use a slightly smaller socket then the bearing and tap it in with my dead blow hammer (one that is filled  with shot).

Isn't there a pin/dowel that aligns the flywheel into the end of the crank?

When I put the 1.6 in the SJ I used the dowel from the 1.3. There was no flywheel with the engine so its quite possible that the 1.6 didn't have one although the hole is there.

Trackicks do not have an alignment dowel in the crank.  There is no reason for it, since the flywheels are balanced and you can't check the timing off the flywheel.
The reason samurais have the alignment dowel is so the flywheel will be indexed correctly, and the timing can be checked through the hole in the side of the bellhousing.  Samurai flywheels are also balanced, so if you don't care about checking the timing via the flywheel, it can be installed in whatever position you wish.
