The AERA Technical Committee offers the following information regarding crankshaft pulley replacement for 2001-2005 Mazda 2.0L and 2.3L engines. The crankshaft pulley is not keyed to the crankshaft on these engines.
If the crankshaft pulley bolt is loosened, the pulley may move its position on the crankshaft. The engine must be re-timed whenever the crankshaft pulley bolt is loosened, removed or replaced. Several service tools are required to correctly re-time all the components.
Follow the procedure listed below to time the cams and crankshaft and tighten the new crankshaft bolt (p/n LF0111406).
Install the camshaft alignment plate (p/n 303-465) to the camshaft as shown in Figure 1.
Install the M6 x 1.0 bolt by hand as shown.
Rotate the crankshaft clockwise until the crankshaft is in the No.1 cylinder TDC position (until the crankshaft balance weight is contacting the crankshaft alignment pin (p/n 303-507).
Hold the crankshaft pulley using the service tools.
Tighten the crankshaft pulley lock bolt in the order shown following two steps using the service tool (p/n 49 D032 31 6).
Remove the service tool from the cylinder block lower blind plug.
Rotate the crankshaft two times clockwise until the crankshaft is in the TDC position, reinstall the service tools to the camshaft and cylinder block, and inspect the valve timing.
If not aligned, loosen the crankshaft pulley lock bolt and repeat from Step 1.
I’ve had difficulty selecting the correct head gasket for Deutz engines. Any help?
The AERA Technical Committee offers the following information regarding cylinder head gasket selection for Deutz 1011 engines. These in-line engines are supplied in multiple cylinder configurations under various engine models.

Height

(55.37 mm)
A notch(s) cut out of the gasket’s outer edge identifies the cylinder head gaskets. There are three different gaskets available and the correct selection is based upon the present piston protrusion of that engine as shown in Chart 1.
There is a third consideration that allows additional component reuse on these engines; there are three standard piston compression heights available. Those pistons are identified by A, B & C markings. Refer to the bottom of Chart 1 (above) if piston selection is desired.
It is crucial to determine the correct components to use while assembling these engines as piston to valve contact is probable if incorrect combinations are used.

Having had the distinct opportunity to view this industry from my chair as editor of Engine Builder has certainly opened my eyes to a lot of great things this industry has going for it. However, my favorite thing about it – hands down – is the passion.
Whether it’s passion for covering the industry (as we do), or passion for manufacturing components (as so many of our partners do), or passion for creating horsepower and engines (as all of our readers do) – there’s certainly no lack of passion here. That all said, where I’ve seen the most passion for what our industry is all about is on the track. That’s where the proverbial rubber meets the road, and where the manufacturing, the engines, the cars, and the people all come together to earn a longed-for result.
First things first – Happy New Year to you all. I sincerely hope you got to be with friends and family during the holidays and that you all had a safe and fun end to 2021. We’ve now officially welcomed 2022, and as the holidays have quickly come and gone, as they always do, I
It’s crazy to think that 2021 is coming to a close. The days and weeks in a year always feel long, but the months and the year itself, absolutely fly by. It’s strange how that always is the case. There’s no stopping Father Time as they say! All we can do is forge ahead and
I’ve actually lost track of how long it’s been since people started claiming print was dead. It’s been a while! Now, I understand the ‘print is dead’ claim might be different for newspapers than it is for magazines, but I can tell you this – the content landscape has certainly been shifting. Related Articles –
Formula 1 racing often tells smaller stories within each individual race; the final stretches of the Russian Grand Prix proved in my eyes that experience always wins.
This month’s column is for all those folks in automotive performance with a small business, as well as those looking to get into this segment of the industry. Automotive performance is this gray area that comes with risks and rewards as well as customers who don’t know what they don’t know. If you’re not careful,
Two years ago this month, I was promoted to editor of this fine publication and brand we call Engine Builder. After having been in the managing editor role for the five years prior, I got my chance to run the ship, as they say, when Doug Kaufman accepted an editorial director role within Babcox Media
This is kind of a gray area for me. Obviously, being a passionate car guy who’s willing to throw turbochargers on anything and really enjoys performance, it creates this internal conflict between wanting to be somebody who participates in a greener view of the future and the well-being of my passion, career and industry.

As we all know, March 2021 marks a full year since the Coronavirus began altering what we used to know as ‘normal life.’ I don’t think any of us will forget March 2020 when we began hearing that this then foreign flu strain was starting to make the rounds in the U.S. I remember we
