Hapy Shifting

In my last post (Hapy not Spittin Fuel), I described a stressful drive home without turbo and then losing access to my 2 lower gears. Today's post covers the install of the Gene Berg shifter, and some other little bits on the bus as well as the replacement of the throttle cable on Oliver the 1978 MGB.
 
Before I begin, especially to my union brothers and sisters, Happy International Labor Day. Employee protections were and remain hard-fought; from a legally defined "work week" to overtime pay and safer working conditions, we have our unions to thank.
 
Throttling Oliver
Gene Berg shifter
I'll start with Oliver, even though I did this cable replacement in the middle of the Hapy stuff. Recall, I moved Oliver out of the shop so the overhead door crew could install the door. At that time, I got Oliver to start, mostly by cleaning and re-gapping his spark plugs and otherwise being patient. Since Oliver does not have a stock carb set up (side draft SK Racing carb), the stock throttle cable is not an exact fit. The old cable had a much longer hard "pipe" to fit the cable through near the carb than the stock one I had ordered. I thought about simply removing the braided cable and sending it through the old sheath, but the points where the plastic sheath met the hard pipe was failing. I think the way the hard pipe was attached to the carb was a little hinky too, so the whole cable, hard pipe combination went in the bin.
 
Both the new and old cables attached to the pedal the same way: round ball on the end of the cable fits into a nook on the underside of the pedal. So, once you pass the cable through the slot, the springs on the carb effectively hold the pedal up through steady tension through the cable. The other end of the stock cable has a fitting on it which presumably fits onto the old carb with a c-clip or similar. I had to cut that off so I could thread the raw cable through the more common hole with a bolt model. Cutting the cable left wire shrapnel at the end, so it would not easily fit through the hole. Ultimately, I had to remove the actuator arm and the spring arm from the side of the carb so I could more directly feed the wire into the hole. While this was more destructive initially, I was getting nowhere trying to send a cable through a hole I could barely see.
 
One the cable was through the hole and bolted down tight enough so it would not fall off, I put the arms back, and re-added the spring. I got Boo to sit in the driver seat and move the pedal through it's full motion so I could set the depth of the hard tube and the cable length. I had other things to get after, so I did not test fire and drive Oliver. In retrospect, that may have been a missed opportunity.
 
Gene Berg Shifter
shifter diagram
I don't know when I first installed the Scat chrome shifter into Hapy. It seems like it was always there, so it may have been one of the first things I did. Back when I first bought Hapy, he did not want to go into gear at all because the shift coupling at the front of the transaxle had lost the little plastic bits. Note the picture on the right, here. In sub-component "P", there are 2 rectangular things. Those are the plastic bits which were gone when I bought the bus. If you threw the shifter in the direction of the gear you were seeking often and hard enough, the long-ish bar thing (top of sub-component "P") would move the cage (center of sub-component "P") and eventually you might find a gear. The prior owner had beaten on the original shifter so much, it wasn't straight anymore. It was literally bent. Once I got the cage resolved, the bent shifter was just too strange to use, so I bought the upgraded shifter. Or at least it was. Over 15-20 years of use, I think it slowly may have moved, though there is no facility to adjust it -or- the limited-throw bits wore down over time. Since most folks think somewhat highly of Scat products, I'll assume it wore down or moved over the years. I will say that in recent years, Hapy has predictably popped out of 2nd gear every time, and I don't remember when that started.
 
greased up
The loss of both 1st and 2nd gear on the drive home was enough for me to do something drastic. After removing the Scat shifter and discovering the rust and what looked like some wear on the plastic bits, I decided to find the Gene Berg shifter I bought a few years ago. The Gene Berg shifter is simply bad ass. It is 3 or so inches longer (Scat is 21 inches, Gene Berg is almost 25) which puts the shifter in my hand without having to bend over like I did with the Scat after adding the Sprinter seats. The picture at the top shows how high it is. One drawback: when I put it in first, I hit the rear of the cup holder. The reverse lockout is a button on the side rather than a "T handle to pull up on. I like that better too, since there is less to think about and backing up a bus requests all of the focus you can. It uses a shift plate like item "D" in the diagram above so for the more stock-familiar, this vibes well. Perhaps the most important, the attachment of the pieces has adjustment capability engineered into it.
 
I test fit everything first, and finger-threaded the supplied bolts into the respective holes, just to be sure everything would fit. Then, I took it apart and greased everything: the ball, the slides, the shift plate, and the cup the shifter tip sets into. Then, I installed it again. One thing about a test fitting is the second time around, you know how it all goes together, making the final fitting much faster. Because of the adjust-ability factored into the shifter, it was easy to wiggle the shifter and the mounting footing to get it seated squarely and threaded snug. I tested the movement of the stick and did not feel a need to adjust it. I figure after some longer test drives, I will know for sure and then execute the minor adjustments. For now, though, I fired up the engine and backed Hapy out of the shop and drove him up and back on the laneway. At this point, I have all my gears.
 
Seasonal Scrubbing
I ended my weekend of yardwork and playing on cars by giving Hapy his spring cleaning. I have documented this in the past, but in brief: I use SoftScrub bathroom cleaner and a soft brush to clean the fiberglass top. This gets all the black ick from organic material removed. Prior to this step, I will clear out the luggage rack of leaves and such. It was especially bad this year so I need to circle-back, remove the rack and clean the metal top. Once the top is SoftScrub'd, I wash the entire bus (top again) with car wash like any other car. The end-to-end process takes 2 or 3 hours, but if the sun is out and it's not too hot or cold, it is a great way to spend a Sunday afternoon. I hope to get the luggage rack removed and the tin-top cleaned next weekend. That will also give me the opportunity to repair any part of the luggage rack which needs attention. In the meantime, I swapped the vehicles around, setting Hapy up as my daily driver and the lower mpg truck for specific-use-only. As of May 1st, regular 87 octane gas is $5.70/gallon here, and diesel is $6.20 but with the mpg difference, Hapy is less expensive per-mile.
 
Wrap
Around that work, there's the usual clearing brush, mowing lawn, etc that comes from living in a house, and spring growth. Our favorite construction contractor was over on Saturday to experiment with the south-facing doorway in the shop. After some large thinking, we are going to put in barn-door style doors, but with fiberglass so the little bit of winter light we get will make it into the building. That's it for this week. Thanks, as always, for following along-
