|
|
Hi
Engine and trans were out for new fuel tank install.
Only drove it a few times since. Was hard 'finding reverse' after reinstall.
Now it wont go into reverse. Seems to go to that position but 'pops/bumps/moves' out of reverse. It does this as if the push down to move into reverse is negated and the shifter pops back up and out.
Is this possibly affected by the lock out plate? It wasnt removed when I pulled or reinstalled the engine.
Every other gear, especially 1st and 2nd shift smoothly. Before engine pull reverse was never an issue.
Thanks! _________________ formerly known as Brown_Bus

Does it shift smoothly otherwise? Have you triple checked your linkage connection at the base of the shift rod under the front of the bus as well as the end of the linkage rod where it joins with the bushing at the tranny?
Sitting in the driver's seat won't tell you much. More helpful to have someone look underneath while someone goes through the shift pattern to observe and listen. _________________ All the redemption I can offer, girl, is beneath this dirty hood

I would guess it has something to do with the grub screw for the shift coupler. |

Is that the screw that is threaded with wire and is also sometimes also held in with lock-tite?
What should I look for with that screw? Too loose? Not there? _________________ formerly known as Brown_Bus

If you don't get the screw centered in the inner hole correctly the coupler can end up out of alignment with the shaft. You would think it would always self center into the inner hole, but this actually doesn't happen 100% of the time. If the screw you has has a sharp point you need to ground it down.

doesn't have a point you need to grind one. If the point is too narrow and too long then you need it to be shorter and fat. The screw must bottom on the sides of the well for it. If it is a factory grub screw it will be fine. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Will twisting around the wire that threads the hole move it out of alignment?
I'd imagine if its tight before twisting the wire etc. that it wont move it out of alignment(or shouldn't).
Ill report back this evening. _________________ formerly known as Brown_Bus

You've had the entire drive train out of the bus for a repair, now you've put it back in. it's obvious to me that all that is not sitting in the same position it was before removal. you need to go back and readjust everything effected by the drive train removal. Like the shift leaver. My money says that is it, a shift leaver adjustment. |

Is that done by loosening the bolts at the base of the shift lever, then with a flat edge moving the lockout plate? _________________ formerly known as Brown_Bus

Yes. if unsure on exact procedure do a search on shifter adjustment. it is a subject that has been covered exstensively in this forum. |

Assuming this is from the viewpoint of sitting in the drivers seat is this the correct orientation for the lockout plate?
I know the thing is a mess, but its probably been there for a few decades _________________ formerly known as Brown_Bus

Yes reverse lock out ramp on the right (passenger) side. |

Ugly as hell your reverse lockout plate is. That said, you didn’t futz with it before, so why would that be your cause now? I can tell you this. A type 4 engine/transmission assembly can be installed either too far forward or too far aft. There are slotted holes in the rear hanger and the front fork mount can be clamped down + or - about an inch which could affect shifting _________________ Lead Mechanic: San Diego Air and Space Museum

Who did the engine and transmission drop? Did they bend the rod during that procedure? Evaluate. _________________ .ssS! |

I removed and installed engine/trans...combo was free of rod etc. before the lowering.
Looking at Tcashs shifted ID parts thread, I think the front shift rod bushing 'may' be a factor...seeing as how it appears to not be there:
also does that rod look too far forward? _________________ formerly known as Brown_Bus

Without a functioning bushing there will be lots of slop in the system. Find the best quality bushing you can get your hands on. Cheap ones will last only a few thousand miles, while quality ones will last for hundreds of thousands. |

1) would no bushing cause the shifter to pop back out of reverse?
2) do I need to pull trans to install that bushing? if no what is involved. Is it just as easy as sliding it over the rod and into the hole the rod goes through? _________________ formerly known as Brown_Bus

You just need to remove the grub screw from the shift coupler so that the coupler will slide off the shaft sticking out of the transmission and unbolt and the shifter lever. This will allow the rod to move back out of the way. |
