    CB water pump on a 87 T1

    I assume I can use an 89+ CB water pump on and old 87 T1 block. I would guess I will be fine as long as I use the smooth 89+ pulley and the shorter 89+ alternator belt.
    Thanks
    Regards,

    I know you can use a non cb water pump on a cb but you have some manageable interference at the edge of the oil pan

    don't know about the reverse application like you asked though

    Miles, Yes they will fit but the CB housing relocates the lower alternator bracket attachment bolt a little over an inch forward and almost an inch upward. So you'll probably need to change out lower alternator bracket too. Of course the lower radiator hose is at a different angle too. This can lead to changing out lower radiator hose to later style one as well. Here is a picture of early and late waterpump housing stacked on top of each other. Just shows the different mounting location of the lower alt bracket and hose positioning.

    Wow, thank a million Todd!!!. I missed the lower alternator bracket attachment difference. I did look at both side by side. My CSX is a 2.5 CB and uses an old style adjuster. I have many old and new style adjusters
    I also noticed that the long bolt that attaches the lower portion of the water pump is significantly longer. Now to find out where my extra CB water pump bolt are....

    why would you want to use the crappy CB water pump anyway, It cavitates the air. The housing is better but the pump blades suck.

    yep, run the old pump, port it's housing especially where it meets the block, a little around the pump fins and inlet on the bottom. Shave down every other fin on the pump and go.

    OK I placed an order for an old style pump arrives tomorrow. How far do i shave down every other fin? I assume you want me to remove every other fin. Does that not reduce pumping flow?

    Miles,
    Since your going to use the early style waterpump I won't bother commenting on the CB pump and housing. You should spend some time porting the short turn radius where the waterpump housing turns to the block entry. There is usually a bunch of sharp casting flash and a large hump in the housing that should be removed. The early housing has a lot of material on the short turn (which the CB doesn't have). You can be very aggressive improving that short turn. I'm attaching a couple before and after pictures of one I recently ported. Huge difference in flow.

    Probably means well but sounds very caustic.

    Definitely means well and sounds very un-caustic, even courteous, always with class!!

    Re: CB water pump on a 87 T1

    Sorry I'm blunt and too the point. I don't have the time to mix words.


    Todd's pics are awesome as always. On mine and others locals have done we open that up all the way to just shy of the O-ring grove. The opening in the block is round. Make it match IMO.

    As for the fins I ground them flush to the wheel they protude from. Yes every other one. You'll see once you have the pump.

    Nothing to be sorry for, we are who we are.

    I wasn't trying to bash you, more like acknowledging Todd's exemplarily and mannerly post.

    Todd is literally dripping with class and informative, detailed and illustrative information.

    I was striving to be like him when I grew up, then I realized it's too late, I'm already older than him.

    However he still calls his Engine a motor, so there's that little imperfection!!

    Thanks
    Randy

    Thanks everyone for the input, I decided to stick with the old style water pump and port using Todd's post as a template. No quite as pretty as Todd's but close enough for a DD.

    ah , there's a reason here
    mass produced automobiles have , engines

    hand built projects of dedication , passion and basic compulsive mechanical fiddliness ...
    THOSE are called RIDES .. and RIDES have motors ... not some mass produced disposable engine

    respectfully , I'll let you in on a laugh I had years ago

    from across the room , using my tv as the computer and without my glasses
    - your site user name kinda reads as
    gunslit#2
    (yeah my subconscious .. "he's" really funny , he thinks..)

    I'll add with auto parts store water pumps most every one has needed a little trim just to clear the impeller against the big housing
    - so , it's wise to check your fit first even if doing a simple pump replacement
    I never use the gasket though , just silicone

    Furnaces, wipers, heaters, fridges, etc, etc, all have motors.

    Most Engines also have starter motors.

    Ever notice electrical guys never call motors, Engines??

    It's sad they know the difference but some mechanical guys don't.

    They often call call Engines..motors, sad, very sad...

    Even oil companies are trying to enlighten the unlightened.

    Thanks
    Randy
