Final drive double ended studs came out....

Post by CrawGator » Fri Nov 16, 2018 4:20 pm

In removing the final drive to grease the splines 2 of the 4 final drive mounting bolts unscrewed from the final drive. Threads are good they just weren't tighten very well I guess. Plan is to put a double nut on and screw it back into the final drive. I assume I do not need to use loctite? How tight should I go?

Will they thread in by hand? I would chase down the threads, use loctite and thread them in by hand.

I threaded them in by hand with no loctite. Had to use pliers to snug them up.

Okdokee. Pulled em back out, cleaned holes again, added red loctite and put em back in. Maybe they will stay now.

Am having this issue with my '16cT - how long are the studs? I have been able to attach another nut in place to stop one of them from backing out, but am unable to rethread it into the FD (still on the bike). Did you have to remove it first to remove any stress?

Thanks,

Follow up - tried again - no good - looks like I will need to remove the FD and retry - now the newest saga...it just started puking oil when driving short distance (5 - 10 mi.). Still have a approx. 135-150cc according to the dipstick (hot), and the outside temps are in the upper 80's to low 90's. When checking the fluid, I couldn't touch the FD for more than 2-3 seconds - is that too hot?

HELP!!!

The final drive gets good temperature in warm weather. Like 60 °C and more. As long as there is 1/2" of oil in the fd, the gears will get lubed, so no problem with the amount of oil you´ve got in. I would losen the final drive to screw the stud back in. In fact I would take the final drive off the bike, clean and check the threads. If they are o.k i would use at least red loctite and let it cure for at least 12 hours with a nut screwed on to hold it under pressure. If thead is damaged, you need to repair it. Timesert or other oil tight systems would be great. Helicoil or bearcoil are a bit problematic, because oil could leak through, if it´s not done properly.

When I see Chad´s picture: Forget about what I wrote! The studs are the same as they were during soviet era and up to 2007. To repair them when oil comes through, you have to open the final drive and replace the studs from the inside.
It´s mandatory to check them for tight nuts now and then. Otherwise they will be damaged.

The studs on a Patrol/2wd are different than those 1wd studs.

On my 2010 Gear Up the final drive calls for only 105cc 80/90 gear lube. Is the 135-150cc amount you have a correct value for your year final drive?

Good point, but I was responding to the question-asker that owns a 1WD bike. :wink:

Hey, I see that now, thanks! Talk about hijack and thread drift, or maybe better yet wandering thread :lol: At least we're still talking final drives :roll:

I know we're talking about three different bikes on this thread now but,

Jeff, there was a misprint in the owner's manual for a couple of years... The correct amount for a drum braked 2wd is 135ml(cc), and 105 ml for a drum braked 1wd. You have been under filling yours.
