Gear Drive vs Chain Timing Sets

[befland]

I had a gear set on my old 6.2 engine that broke a crank (not bc of the gear set). I put a different 6.2 engine in the truck and installed a new gear set that a friend of mine bought for a 6.5. I bought a whole box of new/used parts from him when he sold his truck. The gear set was new and since mine had more than 200K on it I decided to put the new set in. It had the reluctor wheel with it but I didn't use it and I used my long snout balancer. Is there any difference in the gear set itself between the 6.5 and 6.2?

Not to my knowledge (other than cost). The reluctor added about $100 to the cost of the Phaser compared to the non-EFI gear set.

That is correct. A gear drive is a gear drive. It becomes a phazer when you add the phazer ring. The injection pump type and the balancer snout length determine whether you need a phazer or not. The electronic balancers have a shorter snout so they would require a phazer to fill the void if used on a mechanical engine.

OK, let me get this all straight before I order the wrong thing, I am going with a GEP motor, ( ordered it today) a military take out 6.5, I have a DB2 pump, and will order a Fluidampr for a manual pump motor, and order a gear drive for a Manual motor ... am I right??

Thanks, Chris

The Fluidampr produced for the mechanical fuel injection engines comes with a spacer to accommodate an installation with/without the reluctor. So, either way you'll be OK when using a mechanical gear set.

How has the long term use on these gear sets held up? Any long term tear down study conducted> I would be interested in seeing the condition of the gear teeth after 100k plus miles.

I have 90K on the factory (Peninsular Engines) AMG 6.5 TD. There was no sign of wear when I replaced the coolant pump at around 50K on the engine. These gears are VERY lightly loaded and in an oil bath, so wear should never be a concern.
