833971 Volvo.Penta Water separator

START BY:a. remove water pump 1. Hold the impeller shaft with a wrench, and use an impact wrench to remove nut (1) from the shaft. Remove pump adapter (2). 2. Use tool group (A) and a press to remove shaft (3), the seal assembly and impeller from the water pump housing. 3. Remove spacer (4) and seal (5) from the water pump housing. 4. Remove snap ring (6) from the housing with tool (B). 5. Remove spacer (7) and bearing assembly (8) from the housing. 6. Remove the seal from the water pump housing with tool group (A). 7. Remove impeller (9) from shaft (10) with tool group (A). The impeller on some water pumps for 3204 Vehicular Engines is not machined on the back. These impellers must be removed before the existing tools can be used to install the new seal assembly. Identification of the impellers that are not machined is as follows: Any impeller with a "9N139X" or "3Y4717" on the back must be removed and a new impeller installed. All service replacement impellers are machined on the back. 8. Remove water seal assembly (11) from the impeller shaft.Assemble
1. Put 2S3230 Lubricant between the bearings. Put spacer (2) between bearing assembly (3); then put bearing assembly (3) in position on a press.2. Put impeller shaft (1) in position, and push it into the bearing assembly. 3. Put a small amount of 2S3230 Lubricant on the seal lip, and install it in the pump housing with tool group (A). Install seal with the lip toward the bearing assembly. 4. Install tool (B) on the impeller shaft; then put the shaft and bearing assembly in position in the pump housing. 5. Install tool (C) on the bearing assembly. 6. Install a suitable driver from tool group (A); then with the press, push the shaft and bearing assembly into the housing. Inspect the seal at impeller end of the pump to see if the lip of the seal was pushed out or damaged. If so, make a replacement of the seal, and do Steps 3 through 6 again. 7. Install spacer (4) in the water pump housing. 8. Install snap ring (5) with tool (D). 9. Remove tool (B) from the water pump housing. 10. Put a small amount of clean oil on the seal, and install it in the housing with tool (C) and a suitable driver from tool group (A). Install the seal with the lip toward the bearing assembly. 11. Install spacer (7) in the pump housing. Install pump adapter (6) on the impeller shaft.12. Put 9S3263 Thread Lock on the threads of the nut; then install the nut on the impeller shaft. 13. Put the pump housing in a soft-jawed vise, and use a wrench to hold the impeller shaft while the nut is tightened to a torque of 170 15 N m (125 11 lb.ft.).
Do not use a hammer or similar tool to hit or drive the seal in place. This will damage the seal.
14. Put water seal (8) in position on the impeller shaft. Put a small amount of clean oil on the seal. Install tool (E) on the seal; then push the seal into the housing with a press. 15. Install 5P7350 and 5P7352 Spacer (11) on the pump housing. Put impeller (10) in position on the shaft. Use the 5P7353 Spacer (9) and a press to push impeller (10) on the shaft until spacers (11) can just be removed between the pump housing and impeller. The 5P7350, 5P7352 and 5P7353 Spacers are all part of tool group (F). If the impeller does not have two 6.35 mm (.250 in.) holes drilled 25.4 (1.00 in.) from the impeller centerline. See Service Magazine Article "Use FT1783 Fixture To Drill Vent Holes In Impeller". This article is dated February 28, 1983, Form No. SEBD1306.16. Install water pump on engine front cover. Make sure vane clearance-to-front housing is 0.28 to 0.84 mm (.011 in. to .033 in.).END BY:a. install water pump
