How can you not love summer? Sure, it gets hot, but it definitely beats the cold, and there’s so much going on to occupy your time. Here at Engine Builder, our team has stayed extremely busy attending racing events, shows, visiting manufacturers and engine shops, as well as our usual content work.
When the timing cover or block has no dowel pins, or the dowel holes do not fit snug on the pins. Take an old damper and hone the center so that it is now a slip fit onto the crank snout. Use it to hold the cover in place while tightening the bolts.
Women in motorsports… need we say more? These nine women do some awesome things in this industry.

Rottler’s SG7MTS MANUALMATIC touch screen control seat & guide machine. It now comes with two modes of operation, MANUALMATIC and manual.

The SG7MTS uses the same proven fixed-carbide pilot tooling as SG7M, but now has a front mount steering wheel for spindle downfeed.
The machine has two modes of operation:
MANUALMATIC – a brand new concept has been added to these machines which should increase productivity by 30-50%. During seat cutting, the operator does not have to operate any buttons or switches, simply turn the spindle feed steering wheel up and down and the control takes care of all the functions like workhead float/clamp, pilot centering in the valve guide and spindle on/off. When depth of seat is reached, the control automatically changes spindle RPM to high/finish speed to give equal depth of every seat and consistent surface finish results.
MANUAL – the buttons on touch screen are the same as the previous SGM machines. There is no external dial gauge, the spindle vertical position is displayed on the touch screen. Simply feed the spindle down until the cutting insert touches the valve seat, touch set zero button and then the digital display will show exactly where the spindle is at all times. The change from low to high/finishing speed is easier as there are two separate buttons. The foot pedal for clamp and float of workhead has been eliminated and now controlled on touch screen for manual and automatically for MANUALMATIC.
The SG7MTS features Rottler’s trademark CONCEN that guarantees you get the most accurate and versatile machine possible. Rottler combines precision carbide centering pilots with a lightweight air float workhead to give you perfect centering with the valve guide every time. This guarantees the best CONCEN of valve seat to valve guide centerline.
