Pulse-Bac® Upgraded Solenoid Bolt & Pin For CDCLarue® 1000 Series Vacuums manufactured by DustRam, LLC. Please Note: Solenoid is sold separately.
These upgraded solenoid bolts and pins are part of the PulseRam® vacuum but are also designed to retrofit all *Pulse-Bac® *CDCLarue® 1000 Series Vacuums PB-1050, PB-1050H, PB-1150, and PB-1250.
When a solenoid pin breaks, then the corresponding filter it controls will instantly stop automatically cleaning. Within minutes that filter will become completely clogged and your CFM will be cut drastically, causing a potential issue concerning the OSHA Silica Dust rules. Repairing a broken pin now requires the vacuum to be partially disassembled for repair.
If this happens on a job site and you do not have any additional vacuums on location for redundancy, then you are dead in the water until you can get this fixed. How many of you have had this happen?
Broken pins affect the up-time of your vacuum, meaning lost production and lost revenue. DustRam, LLC was frustrated by this situation happening repeatedly and set about to manufacture a solution. This product is one of many items manufactured by DustRam, LLC.
PulseRam and PulseBac® Model Solenoid
These upgraded bolts and pins are made from Chromoly Steel, then black-oxide finished to prevent corrosion. The threads of the custom bolt are 1/4 x 28, allowing for very precise valve adjustments.
The pin is approximately 3/16 in diameter, and a #11 drill bit (easily found at Ace Hardware) is used to drill out the hole of the solenoid piston. The pin is designed to fit precisely through the newly drilled solenoid-piston hole without sloppiness.
Once the new solenoid bolt has been mounted into the solenoid piston, then the new pin can be used to attach them both together. There is a small nylon washer used as a spacer, which goes over the end of the pin with the small hole for the clip. Once the nylon spacer is in place the small clip is inserted through the retaining hole of the pin. Be sure the small clip is placed in a vertical position, then place a small drop of Blue Medium Permatex thread locker on the clip where it is inserted into the pin. This will keep the clip in the proper position until such time as you need to pull it out at a later date. Use a small pair of needle-nose pliers to remove the clip when this becomes necessary.
Here is a quick instructional video on how to drill the solenoid piston with the #11 drill bit, then finally the assembly of the bolt, pin, and clip to the solenoid piston.
Replacement solenoids are also available for purchase through DustRam, LLC either as a stock solenoid with the standard piston mounting hole you already have or with the piston mounting hole pre-drilled with a #11 drill bit.
