Description

Timing Belt Gear Dowel Pin Kit (06A BLOCK) | 1.8T 20V 2.1L TDi Crank (NLA)One of the major weaknesses of the 1. 8T 20V platform is that the timing belt system is slightly under specced for the large load placed on it by the 20v head. This shows up in belts that fail earlier then expected. When RPM's are increased, more problems happen with this system. Under high rpm usage, especially in engines equipped with stiffer valve springs, the keyway has been known to shear off the crank pulley, even when the bolt was properly

One of the major weaknesses of the 1.8T 20V platform is that the timing belt system is slightly under specced for the large load placed on it by the 20v head. This shows up in belts that fail earlier then expected. When RPM's are increased, more problems happen with this system. Under high rpm usage, especially in engines equipped with stiffer valve springs, the keyway has been known to shear off the crank pulley, even when the bolt was properly torqued to OEM specifications. In order to combat this, IE has sorted out a dowel pin strategy, placing a 7200lb shear strength alloy dowel pin through the joint to hold the load, even when there is not enough friction on the joint. Ordinarily, this would mean a trip to the machine shop with the crankshaft, but our kit allows the crank to be successfully modified even in the car. The kit starts with a brand new OEM timing pulley, which has been drilled, reamed, and then chamfered in our CNC Milling center. This ensures that the bore is placed right on the money and square to the end of the crankshaft. The kit includes a pulley, drill bit, reamer, high strength alloy steel dowel pin and 2 page instructions with pictures.

Further machined to fit directly onto the MK4 TDI crankshaft for 2.1L Stroker Builds.

These now come standard with two holes, and two dowel pins. The second pin is optional, and recommended for extreme HP and RPM applications

Works and fits my vehicle.
Size: 5424WS, Style: Workshop
The price is reasonable and was delivered on time. It’s a filter so there’s not much you can grade this on unless you do scientific analysis. Be certain to buy the filter that fits your car.

These are great filters for the money. The car dealer wanted 80 dollars to replace it. This can be done by anyone and buying it on here is even more savings. Do not fall for it at the dealer. Save your hard earned money!
