Installing the PS pump assembly to the engine/engine mounted bracket.

Two bolts up front to secure the front aluminum bracket:

41.jpg

One bolt on the rear, "Rockford", to hold rear aluminum bracket to the steel block bracket:

42.jpg

The long "double threaded stud" goes through the front aluminum bracket and threads into the steel block mounted bracket:

43.jpg

Remove this bolt:

44.jpg

Flat black plate bracket goes on next. I had to temporarily install the long/dangly aluminum bracket to the head studs, tighten the front nut down, to get everything to line up. The whole assembly is a huge PIA to install. Leave everything loose, tighten some parts, to get all the holes to line up:

45.jpg

Tightening down the front nut to aid alignment:

46.jpg

And finally, all brackets/bolts/nuts/installed:

47.jpg

Pulley alignment between the crank/WP/PS pump is OK:

48.jpg

Alignment off one groove between the PS pump pulley and the idler pulley:

49.jpg

Alignment good between the alternator and its idler pulley:

Note for later, the slight gap between the alternator idler pulley bracket and the big aluminum bracket. There is no adjustment possible here:

51.jpg

On the power steering pump/idler pulley misalignment, easy fix: I took out the factory spacer, installed a shorter spacer:

52.jpg

Near perfect alignment:

53.jpg

Picture from FSM showing serpentine belt routing:

54.jpg

Belt installed:

55.jpg

Don't forget, like I did, to install this little plug BEFORE bolting the alternator into place:

56.jpg

Belt adjustment at the passenger side on the alternator:

57.jpg

Belt adjustment at the driver side PS pump:

58.jpg

Seems to be OK:

Hard to see, BUT I have a misalignment between the two idler pulleys. The idler above the alternator is twisted:

61.jpg

You can see it clearly here:

62.jpg

Not so much here:

63.jpg

Long, black steel straight edge from the face of alternator idler pulley to the face of the PS idler pulley:

64.jpg

Note the misalignment:

65.jpg

Removing the alternator so i can remove the idler pulley bracket. Now you know why I clean all this stuff LOL:

66.jpg

Idler pulley bracket pushed to stop on aluminum bracket, no change:

67.jpg

As far as I can tell, the steel idler pulley bracket is not damaged or twisted, fits tight into the holes in the aluminum bracket.

So, I loosened the large aluminum bracket from the block, installed one thick washer/shim at the front upper mounting bolt hole, slightly twisting the whole assembly:

Much better, I don't think this slight difference is worth pursuing:

69.jpg

Spinning fine:

70.jpg

After the above shimming, the belt sits center of the water pump pulley. Before, it was riding toward the rear of the pulley:

71.jpg

So, hopefully, good to go.

I pulled out the #2 plug, which had damage. This time, good to go!!!!

72.jpg

So, with the belt back on, no damaged spark plug, and the engine running about 95%, 95% of the time, I am going to leave this one alone for now.

Time to work on a Scrambler!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I ran into that with NAPA on my son’s J-10. I bought their pump with no resevoir, it destroyed the existing reservoir, something was out of spec. We found one with the reservoir at O‘Riley’s and it was way cheaper too.

The pump is the same for "V-Belt" or serpentine, only the pulley is different.

Looking at NAPA online today, I can get the pump with or without the reservoir :shrug:

I have successfully installed a "new" pump into an existing housing several times. Like you said, maybe the wrong pump in the box or something else really strange going on :shrug:

I’ve done several over the years, something was off on this one. I even took it to a shop I’ve used with several good mechanics, they couldn’t make it work either. The pump is in it’s box, on the shelf in my shop...want it? My son never returned it.

No, I don't need it :thumbsup:

Yeah, must have been a defective pump body :shrug:
