Coupler 4" OD Universal Diesel or Perkins (for purchase w/new prop 1" shaft)

Part #: Z2736
$99.35

This is an after market coupler for the forward end of the prop 1" shaft. The output shaft of your transmission is equipped with the mating (but different) end. This coupler is one of two (the other is suitable for use with a Yanmar diesel) that can be ordered with a new shaft so that they may be faced with the new shaft.

Four use on:
• Universal diesel engine
• Perkins diesel engine (with a Hurth transmission)


Please note in the memo field at check-out:
• Engine Make
• Engine Model


If other than a Universal diesel engine, also note:
• Transmission make
• Transmission model


Includes:
• 2 hardened set screws
• 4 hardened bolts 10mm dia
• 4 nuts
• 4 locking washers

Although this part number is appropriate for either a Universal Diesel or Perkins engine with a 4" OD coupler, We must know the make and model of both your engine and transmission to achieve a proper match.

• Flange diameter: 4"
• Shaft diameter: 1"
• Bolt Circle diameter: 3-1/4"
• Pilot Ring diameter: 2-1/2" (male on shaft end)

1) All transmission couplings require proper fitting & facing to the propeller shaft to ensure concentricity. Specialized machinery and tooling are required to properly install a coupling to a shaft. It is strongly recommended this work be performed by a qualified machine shop or boat yard.

It is also mandatory that the shaft be dimpled to match the coupler set screws prior to use. These dimples prevent the shaft from pulling out of the coupler when the engine is shifted into reverse.

See "Face the Coupler to the Shaft" below for these services to be performed when a new shaft and coupler are purchased as a set.

2) This coupler is a special order item. If you would like the OEM part, which is often available for immediate shipping, see part Z2404.

4) Please note your engine and transmission information in the memo field available at check-out..

5) We will bill A 50% nonrefundable deposit to your credit card when we accept your order for this item. The balance will be billed when the product ships.

6) This is a custom made part. You provide the information we need to build this product for you. Once you order it we are going to build it just for you, just as you asked. We never want to see it again, and no one else wants it either. So be careful and order it correctly the first time because it can't be canceled, returned, or magically changed into something different!
