Speedometer gear stripped

Postby BudK » Sun Apr 22, 2012 6:25 pm

I just got back this week from a very nice ride in Death Valley..Ride Report at viewtopic.php?f=2&t=21630

The T ran fine all the time except that I lost the speedometer gear on a long climb. The speedometer went into wild fluctuations (much more than "normal" :D) and then quit completely.

After my return, I pulled the cable and found it to be OK and then checked the gear after removing cable and collar at the gear box, took out the gear with a magnet and saw how it was badly stripped and was not contacting the worm splines on the yoke shaft that goes back into the flex coupling.

After reviewing several other postings on this same problem (Thanks, Steeds), I wonder what the cause/causes might be... seems a poor way to run a speedometer cable that has too many bends from gear box to speedometer. Poor metal in gears??

The fix is rather simple but time consuming (for me) and since the T is still in warranty, I called Logan and he agreed to take care of it.

Seems other's failures have occurred around 10000 km as well... There should be a better way to drive the speedometer! :?

It has not beeen a major problem. I and a couple of others have experienced the variable Russian metallurgy . Hopefully it won't happen again for a while. Was not a major repair, just time consuming.

If it makes you feel any better, my 20 y/o Beamer's speedometer has a twitch that cannot be tracked down. My two shiny lincolns... I'd re-cable it with a product made by a local shop or a reputable cable maker. Just good material.

My 2010 Patrol is in the shop right now for the same (warranty) issue. Mine gave out at 8K.

Lost mine also at about 5,000km. Using Zumo also but sure liked the odometer as a fuel gauge and milage recorder. I do use the gauge in the Zumo now.
How difficult is the replacement?

It is a simple repair. Look at the MYural.com site. Check both gears for wear before you order parts. If the output fork on the back of the trans is worn at all get both gears. The hardest part is getting the castellated nut off the out put shaft. I understand they are using nylock nut on this now. If so get one of those also.

I would love to do it myself, but, since it is still under warranty and the dealer is only 30 miles away.. I'll have them do it..
Hadn't heard about the Nylock nut on the output shaft, CD... will report back after fix!

Mine has now failed twice in 15,000 km. First time it was in warranty, and Logan took care of it, as well. Now it's gone again, and I am out of warranty, and a day's drive from a service center. I bought the flex coupling, speedometer drive gear and seal (as well as a spare doughnut), and plan to repair it myself. So far, have pulled the F/D and drive shaft. Is it possible to remove the flex coupling without pulling the gearbox out. The doughnut is a very tight fit, between the flex coupling and the swing arm. Any advice?

Pull the swing arm.there are some who say that the donut CAN be removed without doing that but to get the fork at the rear of the tranny out it will be a lot easier to have the room.

Thanks Craig! That was going to be my next guess.

Yours may have a nylock nut holding the fork on the tranny shaft. I think 11 was the first year for that but not sure. Mine had a castellated nut down in a recess with a cotter pin through it. It took more time to get that cotter pin out and replace than the whole job otherwise ! I would get the nylock nut for replace if you don't have it already. When you have the swingarm off good opportunity to lube the swing arm bushings and bolt to keep it from corroding . there are bearings in the frame too.
