      Paul my 13B Cosmo pump is not Kubota like

93+ 13BREW(series 6 down

under).

 The 13B Cosmo pump is same as 89-91 13B

(standard rotation) using
poly-V

belt

 as previously posted.

Are you sure about the belt routing?

Paul Lamar

     Yes to belt routing. All pulleys for poly belt

are ribbed and were
intact

as removed

 from car on my 13B Cosmo engine. The 93+ 13BREW RX-

7 water pump pulley is

smooth and runs

 against the flat back side of the poly belt in

reverse rotation. All other

accessories

 (alternator,air pump,pwr steering pump,etc)turn

standard rotation.

So yours is like a 88-92. RX7 correct? I think the

aluminum cartridges only

fits the 93 and up engines.

Paul Lamar

       The 93+ 13BREW RX-7 (US version) Kubota cartridge
only fits the 93+
 housing. I believe Marc Wiese indicated in previous
post that the 93+
 housing would bolt up to 86-91 13B with longer studs.
       The only difference I have noted between 89-92
and my 13B Cosmo TT is the flat poly belt instead of
V belt.
