Title: flywheel index & pilot bearing alignment
Post by: Surfingfool 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

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!

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).

my trackers didnt have a pin or a hole for a pin like my samurais have had of course mabee some do

Post by: Skyhiranger on March 16, 2009, 11:47:36 AM: 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.
