This Awesome Assembly Lube is used on all our engine rebuilds here at Essex Rotary, It makes the assembly of tight fitting close tolerance parts a breeze while still offering excellent protection for parts like stationary gears on initial start up.

Here is what Royal Purple have to say.
Max-Tuff is an ultra-tough, synthetic lubricant. It’s designed for engine builds and repairs. Max-Tuff utilizes unique, synthetic molecules that adhere to metal surfaces to create a formidable, load-bearing physical barrier between surfaces. This minimize the metal-to-metal contact and wear in boundary lubrication conditions, and provides excellent protection against rust and corrosion of both ferrous and nonferrous metals.

PERFORMANCE ADVANTAGES

• Greater wear protection
• Clean, efficient equipment
• Extends equipment life
• Compatible with conventional mineral and synthetic oils
• Non-foaming
• Outstanding rust / corrosion protection
• High temperature service capability

Genuine Mazda Rotor Bearings
These are the standard rotor bearings for 12a and Early 13b’s including the RX-7 FB/SA22c and FC3s

Please note these are the most common size however we are able to offer an oversized option for the Fc3s if required
These bearings are sold as a pair (2 bearings) so one for each rotor.

Please be aware that if these bearings are out of stock it may take up to 3 weeks to get your parts to you, if you require fast delivery then we recommend you contact us prior to placing your order so that we may check availability and pricing for express delivery.

Sold as a Pair these stationary gear bearings where used in many of the early Rotary engines

These include

• RX-7 FB/SA22c
• RX-7 FC EGI
• RX-7 FC Turbo II
• RX-8 192ps (4 Port Manual)
• Rx-8 Auto (4 Port Automatic)

These bearings have fewer “windows” but are the correct bearings for most 12a and early 13b engines (with the exception of the 13b REW found in the RX-7 FD3s)

If your looking at these for your 4 port RX-8 engine then a popular upgrade is the high power multi window bearings though there is no locator notch found on the high power bearings here at Essex Rotary we install them in conjunction with a high quality “bearing lock” compound to help keep them in place.

Sold as a pair of bearings.

if out of stock please allow up to 3 weeks for delivery, if your in need of these parts quickly then we recommend you give us a call prior to ordering.

Thanks to our close association with the new UK distributor of Goopy Performance products Essex Rotary can now offer this superb proven more durable alternative to the standard Mazda Apex Seals.

Goopy Apex seals have become renowned for their reliability by withstanding up to 50psi in Drag Racing and still not failing and have even withstood detonation that the Mazda Apex seal could only dream of.

This makes these High Performance Apex seals not only ideal for any N/A, Turbo or Supercharged RX-7 but also ANY standard or tuned REW or 13bt engine .

Also available for the RX-8 engines these seals can be included in your Essex Rotary engine rebuild upon request at a small additional cost.

Sold at a set of 6 complete seals these will easily replace the stock apex seals found in all series 4- series 8 RX-7 engines.

Goopy 2 mm apex seals are .075″ (1.905mm) thick and you should be able to slide a .0015″ feeler gauge into the rotor apex slot with a new apex seal in place.

Goopy Performance 13B 2 mm oversized apex seals measure .078″ +/- .001″ (1.981mm +/- 0.025mm). If your rotor slot measures .077 – .078″, then you may benefit from our oversized 2 mm seals which will allow you to re-gain the .0015 suggested clearance.

If your gap with the seal in place measures .002-.005″ it is still usable, but keep in mind that tighter clearances means greater sealing characteristics.

Due to their increased popularity please allow up to 21 days for delivery
