Lynx II, hull # 4225

[Peter Duggan]

Guys,

Gerry bought the LH inner spacer for the front wheel bearing which had 11 thousands machined off and the steering wheel which had the addition of a set screw opposite to the loose keyway.

A couple of test runs had the Lynx tracking as it should and NO desire to develop a shimmy after tackling multiple bumps at speed. It appears that there were multiple issues. In summary, alignment, loose LH wheel bearing, sloppy steering wheel, and what I consider the most significant was the loosened U bolts on the front axle.

After the sense of relief following some great runs, the Lynx decided to give me a dose of reality by locking up in fourth gear.

C'est la vie, Peter

The lynx here will let you sneak out of a gear and then put in another gear like reverse. It will lock up the transmission. I find one just has to be very robotic and careful on the shifts, keeping the shifter in 90 degree movements as opposed to jaywalking it through the gate.

Glad to hear you got the shimmy figured out, Peter.

Your last photo almost looks like bocage country in Northern France.

Rob,

Thanks for your comments. You're quite right. I had just got back home from a great run through the countryside, parked and went to shift into reverse and was a bit slaphappy.

Any suggestions or hints as to how to best unlock the transmission. I decided to let it soak for a bit before I tore into it.

Thanks again, Peter

Peter,

While Rob has evidently had to deal with this issue before, I can only offer a suggestion.

Ref your image on page 3 post 66 of the remote shifter and the 3 linkages to the transmission: Can you access the three shift-rods from underneath the vehicle or are they hidden by a skid plate? If you can access them can you move the third/fourth gear rod into the neutral (central position)?

Please ensure the park-brake is firmly applied, and wheels chocked before anyone crawls underneath!

Had this happen in an old tractor crane of mine, and usually the only way was to take the gearbox top off and re-set the gears and gates in the right position with a big screw driver. Having said that you should be able to access the side of the box from underneath the Lynx, but if reverse is really jammed, you may not get it back in by working the remote shifters, your only option maybe gearbox side off, as , as you know the lid is mounted on the vertical , instead of in the horizontal plane like standard trucks, Cheers Andrew.

I was always able to go back into the gear last used and re-shift it.



Colin: The shift rods are accessible, and should be able to do what you are speaking of. I am pretty sure the "skip" is in the remote gear change box.



Pretty sure I have told this story before as well: When I first started working on this Lynx, it would get stuck in third or fourth gear (can't remember for sure now). After doing a ton of work on it, during the road test it got stuck again. I managed to work it onto the hoist, and was ready to drain the transmission to pull the shifter when I noticed a cotter pin missing on a clevis pin on those remote rods. The pin would sneak down and get jammed on a neighboring pin. Cheap and easy fix: a 2¢ cotter pin.

Guys,

The problem was with the front shifter linkage and not the transmission. Drained the transmission and there was no metal or debris in the oil. Jacked up the rear wheels to remove any load from the transmission, removed the inspection cover for the rear shifter, couldn't find anything amiss. Moved to the front shifter and barely touched the 3rd/4th shifter and it popped into neutral.

Road test suggests there is no problem with the shifters but that some driver training is required.

I had a Mustang car suddenly give me a loose shift lever and no gear change. After it was towed, and an hour of shop time, the culprit was a similarly negligible detent ball somewhere. It might have been .50¢ on the invoice.

And good discussion of how to keep old vehicles running after all the usual chatting about rebuilding them.
