Goodson offers a very handy pushrod concentricity checker that allows quick, easy and accurate inspection for bent pushrods. Simply lay the pushrod onto the checker’s rest platform, zero the dial indicator and rotate the pushrod. You can buy the checker alone and supply your own dial indicator or you can purchase the dial indicator from [...]
The drawer design, gauge and high-quality roller bearings provide drawer movement that is effortless and extremely smooth.
If you have the budget, adding a HEPA (High-Efficiency Particulate Air) air filtration system is a great idea. A HEPA filter is designed to trap at least 99.7 percent of airborne particles down to 0.3 microns in size. A HEPA filter approach for a ceiling tile application includes a series of overhead HEPA filters with motorized fans (these mount in the ceiling tile areas in the ceiling grid, just as the tiles mount). The fans are located overhead of the filters. These draw air that is filtered and clean into the room. In order to balance room pressure, you also need vents to draw air out of the room.
Thank you very much. The DOHC 2.4L head in this 2001 PT Cruiser spit the No. 1 spark plug without warning, taking the threads along for the ride. We suspect this resulted from poor thread quality coupled with a relatively low spark plug torque value. It appears that cylinder pressure worked its magic on the [...]
PRO-LEVEL SPARK PLUG THREAD REPAIR MADE EASY If you haven’t run into this problem yet, it’s very likely that you will in the near future. There seems to be a rash of spark plug thread failures in a variety of later-model aluminum heads. The most common is the 4.6L Ford head simply because some design [...]
The camshaft was checked with a degree wheel. Crane did one heck of a nice job grinding this bumpstick. Lift and timing moments were dead-on to the cam card. With our crank snout pinned for the damper, the timing cover was installed using ARP’s front cover kit (12-point stainless). The front coolant balance tube assembly [...]
continued from Part 2 Considering the anticipated forces that a set of rod bolts will encounter during high-performance engine use, it doesn’t make sense to compromise by tightening with torque alone. Two examples of rod bolt stretch gauges. A variety of manufacturers offer these tools. The bottom anvil (stationary pointed pin) is adjustable to accommodate [...]
MEASURING CONNECTING ROD BOLT STRETCH Optimum bolt preload and clamping force is achieved by monitoring rod bolt stretch as opposed to applying torque value. by Mike Mavrigian photos by author Tightening connecting rod bolts while measuring bolt stretch provides a much more accurate method of achieving proper bolt preload and clamping force. Professional performance and [...]
I opted to install the crank gear at the zero timing mark, but this gear allows adjustment +/- 4 degrees. Our timing chain setup installed. With No. 1 rod pin at TDC, the timing dot on the cam gear is at 6 o’clock, and the ) mark on the crank gear is at 12 o’clock. [...]
