Tools Needed(newer hardware included, tools highlighted in red):
Safe means of lifting and supporting the vehicle: jack and jack stands, wheel ramps, or lift.
Socket wrench or breaker bar
17mm deep socket
15mm socket x 2
19mm open end wrench
Flat head screwdriver
E10 inverted Torx socket
6mm allen wrench
Components supplied should include:
1x PMM base
1x PMM bushing carrier
1x PMM top
1 x 16mm bolt
1x 19mm locknut
2x 15mm bolts
2x 15mm lock nuts
Optional: 2x timing cover studs discontinued
Note: 18mm locknut is now a 19mm locknut.
(CAUTION: allow the vehicle to cool down fully before attempting any work)
Begin with assembling the Damond Motorsports PMM as shown.
Assemble the bushing carrier into the base of the mount. The DM logo on the bushing carrier should be facing the front open portion of the base as shown. There is a little lip on the bushing carrier as well that sticks out on one side, make sure this lip is on the same side as the back of the base as shown.
Take the supplied 15mm bolts & nuts, and assemble the base to the carrier, LEAVE THE BOLTS/NUTS SLIGHTLY LOOSE
Assemble the PMM top to the bushing carrier, with the top plate positioned higher as shown.
NOTE: If you have a non-Mazdaspeed or non-MPS Mazda3 or a Mazda5 the PMM top needs to be flipped with the top plate positioned lower
Assemble the PMM top to the bushing carrier as shown, with the 16mm bolt, and 18mm or 19mm nut. Tighten to 60lbs/ft, or until the top clamps around the bushing sleeve. This spec can be tightened with the mount on the engine or by placing the mount in a vice with a rag to prevent scratching the coating. NOTE: There may be excessive play prior to fully tightening and/or with the "street" bushings.
NOTE: THE TOP IS POSITIONED HIGHER AS SHOWN FOR THE 07-13 MAZDASPEED3, AND 2011-2017 MAZDA5. FOR THE 2004-2013 2.0 AND 2.3 MAZDA3, 2005-2010 MAZDA5, AND 2.0 MK3 FOCUS THE TOP PLATE NEEDS TO BE FLIPPED AS TO BE POSITIONED LOWER.
With the mount assembled, it is now ready to be installed in the vehicle.
Begin on the vehicle by properly supporting the vehicle in the air, and then removing the undertray(if the undertray is not equipped, you may not need to lift the vehicle).
Place a jack underneath the oil pan, with a soft material such as rubber or wood, as to not damage the pan, and apply enough lifting pressure to support the engine.
Locate the factory PMM assembly, connecting the engine’s timing cover to the frame rail, underneath the coolant reservoir.
Begin by removing the components covering the factory mount.
For the Gen1 MS3: Remove the 2x 10mm bolts securing the coolant and power steering reservoirs to the chassis, and use the screwdriver in each of the tabs and metal holding brackets, and pull up to remove the reservoirs. Place the reservoir over the front area of the engine bay out of the way of the PMM.
For the Gen2 MS3: Remove the coolant reservoir by inserting a flathead screwdriver between the tabs and metal holding brackets and pull upward on the reservoir. Place the reservoir over the front area of the engine bay out of the way of the PMM.
With the reservoirs out of the way, you can now access and remove the factory PMM.
Remove the 10mm bolt for the grounding wire from the mount, and set the bolt aside. Shown in blue.
Remove the 2x 17mm nuts securing the PMM to the engine. Note: the studs may come up with the nuts. Shown in green.
Next remove the 2X 17mm bolts securing the PMM to the frame rail. Shown in red.
Remove the factory PMM from the vehicle.
Remove the 10mm bolt securing the ground wire to the frame and remove the ground wire. You'll want to relocate the ground wire, keeping in mind one point attaches to the chassis while the other point attaches to the engine. Here the wire is relocated further inward on the frame rail, and the other point attaches to the timing cover. Another option on 2nd Gen MS3's you can attach the chassis ground to AC line tab, and the engine ground to the timing cover, or leave in the original location(if not attached to the factory mount)
Re-install the nuts and or studs that were removed prior, and attach the DM mount to the engine, with the hardware HAND TIGHT or SNUG. Optional: remove the factory studs prior to this, and install the Damond Motorsports high grade engine studs. Thread in the new studs with little force, as on some timing covers they can thread right through. You want the studs to stick out 1.5” out of the top of where they thread into the timing cover.
Bolt the base of the DM mount to the frame rail using the 17mm bolts removed earlier. Note: The engine may have shifted when removing the factory mount, you may have to raise and lower the jack, and position the motor for the holes to line up properly, and tighten the bolts HAND TIGHT or SNUG.
Now it’s time to tighten all the bolts to spec. Begin with a 17mm deep socket and tighten the 17mm nuts securing the DM PMM to the engine. Torque the nuts to 60lb/ft.
Tighten the bolts securing the DM base to the frame to 65lb/ft. You may need to lower the jack if it was raised earlier to fully tighten these bolts.
Remove the jack from under the vehicle.
Tighten the 15mm bolts and nuts on the DM mount to 30-40lb/ft, using a torque wrench and an additional socket wrench or breaker-bar.
Once all bolts are tighten, reinsert the reservoirs into the corresponding metal tabs, reinstall the engine undertray, and lower the vehicle.
Congrats! You have finished the DM PMM install. We hope you enjoy all our mount has to offer. Note: there may be added NVH with the DM mount. We recommend checking the torque of all bolts/nuts again after 500 miles.
