I have 2 split busses which need the pin replacement (one needs it right now, and the other someday in the future). And since bushings will keep wearing, I kinda see it more as an investment rather than an expense (in the sense that it repays itself the more you use it, instead of having to rent it)  .
It's like with so many repair jobs: the tools are often the most expensive factor to consider in the process (besides labor of course if you would have to pay someone to do it for you); the replacement parts themselves are usually very affordable (since they are VW parts  )

You can use a section of all thread rod, some washers, nuts, and a large socket to make a puller to remove the bushings. Look at the front suspension part of the workshop manual for how to remove the upper bushings. How they made a washer with two flat sides to tilt to get inside and pull the bushings out.
Like this:
You use the large socket to act as a spacer to allow pulling out the bushing into the inside of the socket.

No need to use any kind of drift and hammer. Just make up a piece of threaded rod and washers as above and use a socket slightly smaller than the housing to pull the old bearings out and the new ones back in. No bad language, no battered bearings and can be done easily with the beam in the bus. This method means that you can place the bearings accurately in relation to the grease point and bring the top bearing down to where it should be - a couple of mm above the top of the housing.
I've been doing this for over 40 years and have never used a hammer and drift! |

The old worn out pin had lost its function as such, and the kit I bought included a new pin, so I took my old pin and ground down the end of it with a grinder so it has a diameter of just a little under the bushing's outer diameter (the yellow tape is to center the pin in the shaft as you hit the pin with the hammer to drift the bushings out). Worked for me, I jacked the front end of the bus up high enough to do the job with the beam still in place (whack it like you mean it with a large heavy hammer but make sure the drift stays absolutely centered  ).

| Great write up...about to try this myself soon. Has any tried VW part number 133513471 as a suitable replacement pinch bolt? |

I just did the center pin in my truck this week. Here are my notes:
The Drift or an Air Hmmer were insufficient to move my bushings out. I used a length of ¾” threaded rod, 4 big washers and a socket. Welded the nut to one end. Works perfect pulling or installing bushings. Lube and screw with a 1 1/8 socket on a ½” drive. Use a pipe for more leverage. No problems.
Reaming with a new straight flute hand reamer went well, although registering the reamer initially in the beam was hard to keep straight and still, even with a lead in on the reamer. The lower bush seems not as tight as the top bush, which is a firm push with the fingers to move the pin in the bushing. I was thinking to make a fixture off the lower beam to clamp and set the reamer so it is perfectly aligned with the center pin. Then you would not have any unwanted motion during reaming. Any ideas?
Also, I think if your pre fit the new pin/bushings without the wavy washer,seal and cap, you can mark the pin and swing lever rotationally to make assy easier for the bolt to line up. I scribe the bushings also so they go in the right direction. |

That is why I do the whole thing in two steps:
1. remove and replave one of the old bushings and use the other old bushing as a guide for the reamer.
2. Replace the second bushing and use the first bushing as a guide for the second bushing.

Which old bushing first do you recommend, top or bottom? |

That might work better if the beam was out of the bus, but the issue is there is no way to control the reaming, such that both bushings are in perfect alignment with each other. If you do them separately the chances of perfect alignment is not good as opposed to reaming both in 1 pass. A fixture is the way to go, in my opinion |

Following on from my last post. The bolt I ordered had just arrived. VW part number 133513471
The pic shows my original (chewed up bolt), the longer replacement febi bolt and this new VW bolt - longer than the original and retaining the longer non threaded part. The new part is 10.9 strength and the original looks like 8.6.

| Just make sure you dont run out of threads before the swing lever gets clamped to the center pin. May need a washer to get the unthreaded portion the right length, compared to the factory bolt |

I would not use that bolt. As mentioned, it surely looks like it will bottom out before you can get any kind of proper torque on it. I would not take that chance myself (or on a customer's bus).
at the very minimum you should bench test tightening it to the proper torque spec in the pivot arm before installing it "for real" on the bus.

Could use a threading die to make a few more threads.

No pics, but I recall replacing my 71 bus pin 7 - 8 years ago and thought I did everything right. Even so, there was always side-to-side play on the wheel. All other components were changed, and I just thought that this was as good as it gets. The steering box is set up properly, all ball joints are new, etc. Yesterday, while up on jack stands, I can see that although the pin and bracket seem solid, the pitman arm pitches (rocks) up and down as I turn the wheel. I don't thhink I ever noticed this before.
Could I have assembled this together incorrectly? Wrong torque? Bad arm? Any ideas? Should I re-do the pin and bushings on this stock beam?
Ideas and comments welcome. BTW, I don't think the steering wheel olay has changed at all from when the pin was changed. I just got tired of hearing my son complain about it and thought I'd take another look. |

After replacing my pin, it's tight as can be, and steering is precise without endplay on the arm on top of the pin "rocking up" (I've also installed a Creative Engineering steering kit by the way, that helps a lot as well).
So something's off on yours I suspect.

Pitman arm is on the side of the steering box. Think maybe you mean the swing lever arm on the center pin?? If so it just might need the nut/bolt tightened to clamp the swing lever arm tighter onto the center pin. Problem is the inside of the swing lever arm by now may have worn on the center pin, and so that one of those parts may need to be replaced.
It is a good idea to check stuff like this now and then to see if something needs to be re-tightened. Especially soon after replacing parts, that if they do fall apart could make for a drastic change in someones life.
