One fatal flaw of the Duratec / MZR line since day one has been the complete lack of keys/dowels/locating devices on all of the cam timing components. While we're sure eliminating them made it far easier for robots to assemble the motors in production (and scared away shade tree mechanics from working on them), the possibility of slippage ensured disastrous results. The potential for slippage, while remote on a stone-stock-untouched-grocery-getter, was much more a threat on the modified, high RPM motors us folks like to build. 

Massive has stepped in and now offers a complete line up of keyed crank shafts and companion timing chain drive gears!!!

 

Cranks: 

We started with  NEW (high quality professionally remanufactured in the case of the 2.3 Ranger and 2.5 Dura - new from ford no longer available ) OEM crankshafts and added a proper key way to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose. This will prevent COSTLY damage to your engine! Use with our keyed chain drive pulley.

2.0 Duratec - Factory FORGED Unit

2.3 Ecoboost - Factory FORGED Unit

2.3 Mazda DISI - Factory FORGED Unit

 

Gears: 

 

We started with A brand new Ford ? Mazda chain drive gear and EDM cut a proper keyway to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose. This will prevent COSTLY damage to your engine! Use with our keyed crankshaft. Includes key.

We've always felt the cam gears don't need a key way or dowel - Allowing them to orbit whilst installing the timing chain is a must. Additionally, there is far less chance for slippage, reuse the now unnecessary diamond washers from the crank pulley on them if you please, run some loc-tite as well. 


Keyed gears and cranks are sold seperately

Great summer shoe for 8 month old.
Amazing fit for summer baby attire. Fits true to size, soft, easy on easy off. The Velcro is tearing up hos car seat though, because some rough surface is exposed.

Unsafe Buckle - Risky for tiny fingers
Special Size Type: Toddler (1-4 Years), Size: 12-18 Months Toddler, Color: Stuart Navy Canvas
I at first really liked these sandals, however once my son started learning how to undo the Velcro strap, his fingers began to catch painfully in the decorative buckle. Now I see the sandals as an unsafe option and have subsequently tossed them.

Cute but a little stiff
These are cute and well made. I think the sole is a little too stiff for babies learning how to walk that are used to bare feet. The back of the sandal also slips down sometimes. Overall a decent purchase if you just need something for looks more than function.
