Hi everyone! After more than six months of work in which they have rebuilt the engine with new final drive, and replaced other parts such as the steering box, modern driveshafts ... etc., finally after my first test I notice one thing:

- Before, when putting it in reverse gear, from the center or dead center of the gear lever you moved the lever to the right (a short movement) pushed back, and the gear was engaged. Now to engage reverse gear, the lever goes MORE to the right than before and you can't find the place for it to fit. Therefore you have to go back a little to the left until you find the seat of the gear. So it is more uncomfortable and imprecise. Why does this happen?





Thanks in advance.
Luis

Does adjusting the reverse light switch slightly further in work as a limiter for movement in that direction

If so turn car off, put into reverse and then wind that in until you feel it stop and check the light is on I.e button is depressed fully

Or does that only engage once you do the downwards movement. I can't remember

Hello Stuart! I appreciate your response, but my car does not have a reverse light. No rear light or sensor in the gearbox. It's a 1972 Mini Morris (now 1310cc) with 'remote' gearchange system.

Have parts 30 and 34 been installed reverse gear spring and detent plunger?
These should be fitted beneath the big hex plug on the front side of the gearbox case.

Thank you very much for your response Imack. Sorry, I'm not able to read any of those references in your screenshot, it's very blurry and there are hundreds of those photographs on the MiniSpares page. I've been searching for an hour but I can't find this specific pic. If you would be so kind as to resend me that or link ...
As for the "reverse gear spring and detent plunger", I can't confirm you if it was fit, the engine was restaured by someone who is supposedly an "expert". He claims to have made more than 100 engines. What I know is that I'm without a car since the end of October and everything has been problems until now.

Beautiful... thanks a lot Stuart. Now I can see what friend Imack was referring to.

Assuming that the gearbox is well rebuilt, the question is: could I solve the problem of the gear lever moving so much to the right by adjusting what I show in this photo?



Kind regards
Luis

I presume that photo is of your engine and gearbox. If so, the knuckle joints have not been fitted to the appropriate shafts. I don't know whether this will cause your issue though.
If I understand your problem correctly, it sounds as if the shaft that is entering the gearbox is getting pushed too far forward and moving slightly beyond the reverse shift rod fork.

Hi Imack. Yes, that's my engine, and the joints are mounted backwards. You have been very observant. Thanks a lot.
I don't know if this has any importance in terms of the performance of the gearbox and reverse gear. The car is still in the garage. It would be very important to clear up this doubt.

* Please, more opinions shed light on this mystery.

Confirmed. When the engine was removed to be restored, the gear change knuckle joints are correctly fitted. Nobody in the entire galaxy... can tell if putting them in a different order has any consequences? Incredible!

[imack]

Have you had the opportunity yet to check that the reverse gear detent is in place, or tried refitting the knuckle joints to the appropriate shafts?
Both items are relatively easy to check or refit correctly with the engine in the car.
I don't actually know whether either of these items will cause the shift rod to "overshoot" the reverse gear shift rod fork, and you'll probably find that the majority of people on this forum are familiar with the workings of the rod change gearbox rather than the earlier remote/magic wand type.
I'd guess that if the fault doesn't lie with the knuckle joint orientation or the the detent, then it's going to need a gearbox strip down to see exactly what's happening.
Has the remote shift lever been dismantled? Although I'm not sure that it can be reassembled incorrectly.
