I had the same problem. If the o-ring is good you need the seal (Part # 827247) that goes between the spline shaft and the pump rear housing. If the bearing is bad have a shop press out the shaft and replace the bearing.

Re: raw water pump leak

thanks for the parts info. how do you seperate the pump assembly from the pulley? does the shaft stay connected to the pulley when they are apart. i don't see any retaining rings to hold the bearing in place. or does it seperate by using a puller? i want to replace the bearing myself but i don't want to ruin it either.

Re: raw water pump leak

The shaft is permanetly fixed into the pump pulley, Here is a post from an earlier thread.

"I have had the same seal go on my 5.0Gi but it also allowed salt water into the "sealed bearing" directly behind it.
The pump is secured with just 3 very tight Allen bolts. Well worth removing the whole assembly and replacing seal and bearing at the same time.
Local car spare parts dealer had them both in stock, here in Spain. Seal is an ANGUS--DSPM 16287 GA CO 5. And the bearing had a number 93270 on the seal but the rest was obscured by rust. However it is OD 55mm x ID 30mm x 13mm wide. The new bearing I got was manufactured by SNR and is number 6006.EE. The seal was the exact same number and less than a third of the Volvo price. And yes the whole of my engine compartment got sprayed with salt water and the pump lost its prime."

I now have a spare bearing from SKF No. 6006-2RS1 and a spare seal made from Viton (better wear resistance) dimensions are 16x28x7mm. TB / R23 metal cased double lip viton rubber metric rotary seal with SS garter spring. Best of luck, it is an easy job.

Re: raw water pump leak

i took the bearing out and all i could make out on the bearing was that it was an skf brand. the measurements were different than your. my measurements were ID 25mm x OD 60mm x W 18mm only thing close to it that i've found so far is a 6305, which is not exact but close. my seal is the same as yours. looks like all i needed was the seal because the bearing feels good. now that i have it out i don't want to re-use it. wish i had taken it apart before bying a new pump for $300. best i can do is to fix the old one and recoupe some of my money by selling it as rebuilt on ebay. should sell quick compared to prices of the new ones.
