Barry, I agree with James, why are you doing this? The belts are affected more by mileage than by age. 3000 miles is an extremely short amount of miles, and 3 years if an even less significant figure. The belts on my 12 year old TR where like new (really!) when I pulled them out as part of the major service, and the car had a little over 20K mi. at the time. If it were my car I will put it off a few more years, and put a lot of miles in between.
As far as the Waterpump, if similar to the TR (which I believe is the case), a rebuild is your only option since it is integrated into the engine block. A rebuild comprehends seals and bushing, the nut that holds impeller to the shaft, and the butterfly washer; that is all. Impeller, shaft, bearings, should still be as new (worth inspecting though). |

Barry - why are you doing a 30,000 mile, 5 year service now? I would wait 5 years or 30,000 more miles. Just curious about the state of your mind, and perhaps, your pocket book.
As far as the water pump, all that one does during this engine out is to change the bushing and seal. The impeller stays the same. The bushing and seals should be changed, as any seal should be that is difficult to get at. The bushing was updated from the 1986 to 87 year. Many of the TRs tend to leak a little water out of this bushing, and if it is really bad, water can seep into the oil past the round rubber seal along the shaft that drives the pump. Just simple precaution.
However, I must ask again, why do it now? You had a 30k service 3 years and 3,000 miles ago. If everything is working, let the sleeping dog lie.

Ric: Can you elaborate on the design problems with the TR water pump, and how it was resolved in the 512TR? Can one switch the TR pump to the newer 512TR design?
Thanks. |

Thanks for all your advice, the car has done a total of 33000 miles, but only 3000 miles since last belt change!, but that was over three years ago. It looks like I'll be changing just about everything! including front crankshaft oil seal. Again, many thanks for all your help, Barry Castelete, Hertfordshire, UK. |

I agree with the others, don't just replace the pump but rebuild it. Never know what will happen with it in another 3-5K. And if it has never been done before. I am just sitting here wondering how those bearings must look.
A dollar spent now is worth 100 later...
My 2 cents.

How many miles? Has the car sat for long periods without use?
The TR's had waterpump design problems, but the 512TR's had overcome this. It became standard practice to rebuild TR water pumps everytime the engine came out. I don't know that it's necessary for the 512TRs however. |

On the standard TR, the engine and subframe drop out the bottom to get at the front of the motor for anything other than v-belts.
for the 512TR, just the motor/transmission powerplant pops out the top without any subframe. |

as michael elluded to, you should not change the whole pump but rebuild the current ones - a much cheaper proposition.
I did not realize the engine had to come out to access the waterpumps on a tr? |

According to my mechanic -- The problem there is, imagine if you put the engine back and then the waterpump leaks in 3,000 or even 5,000 miles -- out comes the engine again. Its cheaper to check the inards of the pump now than to have to take the entire engine out again. The parts are so cheap after you spend the time taking the engine out might as well replace the belts, old hoses etc that could become a pain if they break. |

I'm about to change the cambelts on my 512tr and have been advised to change the waterpump at the same time as a precaution??? Is this taking precautions too far? There is no sign of any leaks or noise from the pump, what should I do ?? |
