At the time of vehicle inspection, it was pointed out that the power steering belt may be loose and worn, so I checked it. Loosen two fixing bolts to move the power steering pump. First, align the hole of the pulley on the back side of the pulley with the bolt, and insert a 14 mm box wrench. The radiator shroud is an obstacle, but if you press it, it will dent, so I will manage to thrust it. The second can be reached by pushing the box wrench from the bottom of the pulley and from the side. If you loosen the two fixing bolts, the pump will be free, so you can adjust by moving the adjust bolts indicated by the blue arrows. I think it was loosened by turning left and tensioned by turning right. It was easier than I expected, so I took off the belt and inspected it carefully. The ridges of the belt seem to be slightly worn, but there are no cracks at all, so I will reuse it. I would like to change it to a reinforced product such as HKS, but since it can be easily replaced, I will not waste […]
It is an overhaul of the power steering pump (vane pump). First, remove the battery, piping near the throttle, auto tensioner damper, and belt. The pump is fixed with three bolts marked with orange circles. In addition, remove the hose that connects to the power steering fluid reserve and the hose that connects to the rack. Those who connect to the rack were removed with 22 mm and 24 mm spanners. It’s hard to see in the picture, but the pump is further fixed to the base bracket with two 14mm bolts. I used an impact wrench to remove the pulley. It’s 17mm. If you think it’s power steering fluid, but it’s bearing grease. It’s popping out. ① Remove the pulley and remove the bolt that connects to the 24mm rack and the bolt that connects to the 12mm reserve.② Remove four 12 mm on the back side.③ Introducing the vane pump. From the right, the back cover, wave washer, vane pump lid, body.④ Gently remove the vane pump so that it does not fall apart. I didn’t move it until I put it on an acrylic board and assembled it. This is a replacement part.Above is the vane pump […]
When it became cold and I started the engine, the roaring noise became terrible for a while, and I was riding in a deception by changing the power steering oil, but since the power steering tank was full of bubbles, I decided to replace the pump for the time being. I think the cause of cavitation is that it has sucked in air, but I don’t know where it came from, and apparently there is no oil leakage. In any case, Subaru’s hydraulic pumps of this age seem to have troubles over the years, including the Legacy, so I’m thinking of replacing them with rebuilt pumps to see the improvement in symptoms. First of all, I got a rebuilt pump, but my GDA power steering pump is a model called 34430FE041, which seems to be out of stock in the rebuilt market. I had a little trouble buying it online (34430FE041 seems to be common with 040, 070 and 071). At the same time, I ordered two hoses connected to the power steering tank that could be easily replaced and a metal gasket on the high pressure side that connects to the pump and prepared them. Return hose 34611FE050Suction hose […]
