Howdy all - Just finished replacing my vacuum pump. With 140k on this one I thought it was time to play it safe.
The instructions in the WSM are pretty brief. It's 43-0618 - if you need a copy let me know but it;s so basic as to be useless. Basically it shows a image of the pump and the text says screw out, screw in. The instructions that came with the pump (from Rusty at $300) were better that the WSM. A gasket was also in the box from Rusty. I removed the fan and fan shroud & rotated the upper rad hose out of the way. I also released the serp. belt tensioner to reach one of the bolts. Once the fan shroud was out of the way things went pretty fast. I did have to bump the engine to align the cam/ramp in the engine so the low spots were at 12 and 6 o'clock. This allowed the pump device in the pump that rolls on the cam/ramp to be in a relaxed position during installation. I used a 1/4" drive ratchet (10mm socket) to remove/replace the 6 screws. Tightened them in a criss-cross manner to evenly pull down the pump. Using that 1/4" ratchet makes it more difficult IMHO to break the screws - but not impossible. Put about 1 oz of oil into the vacuum fitting before reconnecting the firm vacuum hose going to the brakes. Since I am running M1 Synthetic I hope to get 180-200k out of this pump (oil unknown before 100k) but for now I have a known pump.
