Description: The 200Z-SR1 Kit includes two shaft seal retainers.
The top one goes on the cone for the propeller shaft seal. The bottom one goes on the back of the gearbox for the input shaft seal.
Both are held on with three #8-32 screws. Six screws are included. Hold each retainer tightly in place and center punch through the center of each hole. Install screws with red high temperature thread locker from Loktite or Permatex.
The pilot holes for the screws are drilled 9/16” deep. Then enlarge the hole with to a 11/64” drill bit. The threads need to be tapped using a “bottom” type tap.
DO NOT DRILL ALL THE WAY INTO THE CASE!  If this should happen replace the thread locker with a thread sealer.

Description:This is the updated Flywheel and Pressure Plate Assy, tested to 6000 RPM. If you want to keep using your original clutch disc this is the order option for you. The assembly order of the parts has changed so a new installation manual is included. The actual coloring of your parts will vary from that pictured.

Description:This kit includes the same propeller shaft seal retainer as the BW350-SR2 kit, but has a different Input Shaft retainer.
The differences are due to changes in the input shaft seal retainer boss design during development. Early cast aluminum gearboxes will need the BW350-SR1 kit because the retainer boss was shorter and the input shaft seal is flush with the outer surface. This is visible looking up from the bottom of the gearbox. (During development some cast cases may have the taller input shaft boss. If the input shaft seal on your gearbox is seated below the boss surface measure how much and call us.)
The top one goes on the cone for the propeller shaft seal. The bottom one goes on the back of the gearbox for the input shaft seal. See installation pictures below.
All screws are #8-32 x 3/8. The BW350-SR1 kit comes with six screws, three for each retainer. Hold each retainer tightly in place and center punch through the center of each hole. Install screws with red high temperature thread locker from Loktite or Permatex.
Drill a pilot hole for the screws 9/16” deep for all six holes. You can make the depth on the drill bit with tape or a drill collar. Then enlarge the hole with up to a 11/64” drill bit. The threads need to be tapped using a “bottom” type tap.
IT IS PREFERED NOT TO DRILL ALL THE WAY THROUGH THE CASE! If this should happen replace the thread locker with a thread sealer.

Description: This kit includes the same propeller shaft seal retainer as the BW350-S1 kit, but has a different Input Shaft retainer.
The differences are due to changes in the input shaft seal retainer boss design during development. Later CNC machined aluminum gearboxes will need the BW350-SR2 kit because the retainer boss is deeper and the shaft seal fully seated is 0.20” to 0.24” below the surface of the boss. This is visible looking up from the bottom of the gearbox.
The top one goes on the cone for the propeller shaft seal. The bottom one goes on the back of the gearbox for the input shaft seal. See installation pictures below.
The BW350-SR2 kit comes with three #8-32 x 3/8 screws for the Propeller Shaft Seal Retainer. Hold the retainer tightly in place and center punch through the center of each hole. Install screws with red high temperature thread locker from Loktite or Permatex.
Drill a pilot hole for the screws 9/16” deep. You can make the depth on the drill bit with tape or a drill collar. Then enlarge the hole with up to a 11/64” drill bit. The threads need to be tapped using a “bottom” type tap.
IT IS PREFERED NOT TO DRILL ALL THE WAY THROUGH THE CASE! If this should happen replace the thread locker with a thread sealer.
The Input Shaft Retainer is a one-way ring pressed in ring. Simply place the ring over the hole with the tangs facing towards you and press it all the way in to the seal. A short piece of 1 ½” PCV pipe cut square on the end works great for this.

Polyurethane Isolator Upgrade
SKU: PEI-01
Model: PEI-01
Weight: 0.40 lbs

Description: These polyurethane isolators are direct replacements for the REI-01 rubber isolators. They are slightly stiffer and stronger to eliminate engine drooping caused by the forward rubber isolators. Each location, aft left, aft right, forward left, or forward right requires two isolators. The old rubber isolators should be replaced in sets, and the left and right sets must match. It is recommended to replace all eight isolators at the same time. The added stiffness in the aft mounts will help to reduce any side-to-side motion as well. The pricing is for a full set of 8 isolators.
Individually priced at $8.00 each
Price: $60.00 for a full set of 8

Description: These rubber isolators are the same as the original isolators used for your engine installation. Priced as a complete installation uses eight isolators.
Sold separately as needed at $6.00 each.
Price: $45.00 for a full set of 8
