Topic: 1975 400/4 Gear Shift - does this look right?

[MDW]

I am reassembling the gear shift mechanism and something doesn't look right. The gear shift spindle (#2 in the photo) looks like it should align up against two of the pins in the plate drum stopper (#1). Shouldn't the drum stopper move around when you shift gears? I tried to manually shift gear and only got the drum stopper to move a little back and forwards but not click up or down. This makes me think part #2 should be pulling on two of the pins.  Also what does the part marked in yellow do (called the stopper positive according to Partzilla)? Just trying to work out if there is something wrong that I need to fix before putting the rest of the engine together!

Thanks!

Looks like there is another plate missing from the selector drum, and dont want to disapoint but there is way to much jointing compound between the case halves

[MDW]

There is a cover that goes over part #1 which I removed to show the issue I am talking about - if that is what you mean?

[bryanj]

Thats correct, observation only but the small spring at left of picture joining the two levers does not seem extended enough which would suggest that whatever is behind the big red 2 that i cant see is not correct.
What problem are you having as its always good to know why we are looking

[MDW]

I don't necessarily have a problem but I was advised to make sure the gears shift before going further with the rebuild. I tried to do that by hand (using a wrench on the spindle) and nothing seemed to happen which may just be because the engine obviously wasn't turning). I also watch the "Too Old to Die Young" video (

He has part #1 in a different position with the end of part #2 around two pins of part #1. Just trying to work out if I have an issue or if everything will fall into position once the engine is running. Any thoughts?
Thanks

   The gear shift drum stopper needs to ride in the valley not the peak. Set the shifter drum up in neutral and assemble from there. I've got a 400 engine on the floor, so if ya need, i can pull the clutch cover and check it.

[bryanj]

If you have assembled it as in the video you have it right, it will only change gear if you rotate the output shaft whilst trying, occasionaly you need to rotate both sharts

[MDW]

Mark1976: Thanks. Is is possible to get the shift stopper into the valley without disassembling the cases?

bryanj: I thought I had followed the video exactly but you can see that his drum stopper is in a different position. Is that problematic or if I follow your procedure rotating shafts will that fix it?

Thanks to you both

[bryanj]

It just means it is a different gear or a neutral, try rotating output shaft whilst moving gearchange

If that's blue RTV it's the wrong thing to use for sealing the cases.
Need to use Hondabond, Yamabond, or Permatex Ultragrey sparingly.

CycleRanger: What you see is Hylomar

[bryanj]

Dont matter what it is there is still too much of it

[Nurse Julie]

Here's mine and it works perfectly. I would be taking those crank cases apart and removing all that goo, far, far to much and use Hondabond.
As Bryan says, you need to rotate the output shaft to go through the gears.

Thanks

At the stage you've reached, it's a royal PIA to go back and separate the cases, to remove the Hylomar. But I've had advice from the forum that's been spot on and to throw my experiences in, on a non-Honda, I bought a couple of years ago, I did an oil change and cleaned the sump screen. I then had oil puking out the valve cover. Turned out to be a blocked drain hole, which I poked through. I then collected old wellseal gasket compound out of the oil sump screen. The Wellseal was only on the tappet adjuster covers, but the excess from that small area was enough to interrupt the oil flow.

You may be lucky and fine, but heartbreaking as it is, I'd take the advice and clean it up while you can. Peace of mind. 👍

Thanks for sharing your experience. I took a look and there is a small amount of sealant on the inside of the casing which I have removed. There is more on the outside than inside.
