garyS-NJ Posted March 21, 2016 #1 Posted March 21, 2016 I bought a seized 84 xvz12 last year and dud what I had to do to get her running and put on new skins. I checked the rear gear oil level but didn't replace it yet.. will do that when I get around to fork oil and that class error code solder fix.. but just noticed there's a zerk fitting on top of the drive shaft housing.. isn't that an oil bath or is the shaft greased front and rear??
Marcarl Posted March 21, 2016 #2 Posted March 21, 2016 It's supposed to be able to provide some grease to the shaft spline. Actually just makes a bigger mess for you when you pull the pumpkin off. Grease both ends of the shaft spline with proper molly grease and you're good to go. I use Lucas x-heavyduty wheel bearing grease, as well as on the wheel spline.
cowpuc Posted March 21, 2016 #3 Posted March 21, 2016 Indeed, the area that that zerk feeds into is a non-serviced by rear end gear lube oil area. The plug that you pull to put "pumpkin" lube into only fills the pumpkin itself - not the swingarm "tube" that the driveshaft is inside of.. Now all that said and following up with what Marcarl was pointing out, I actually would like to know if anyone has actually pumped enough grease into that cavity thru that zerk that the driveshaft was spinning in grease.. Could be done by pumping and pumping until you could lift the rubber boot up (the one behind the forward bevel gear) and see grease.. Wonder if that rubber boot is sealed good enough that it would keep grease from leaking out when the system got warm from riding.. If it would, this may work great for keeping the U-Joints and splines all running in constant lube and maybe save a lot of wear and tear - sort of simular to a couple old Harley's and a Bultaco I used to have that had a sealed chain system leading to the back wheel so the chain and sprockets actually ran in an oil bath.. Think I might try this on Tweeks this year - if you ride with me this season it might not be a bad idea to ride in front of Tip, Tweeks and I until we see what happens (of course, this may be difficult for you 2nd Gen or Harley riders but that is a whole nother subject )..
Trader Posted March 23, 2016 #4 Posted March 23, 2016 Hey Puc! In your expert opinion.... I installed the 1 piece cast type shift sequence found on a 2nd gen in place of the stock 2 piece part on my 1st gen Do you think this transplant will slow my bike down?
LukeMacPU Posted March 23, 2016 #5 Posted March 23, 2016 How many grease zerks are there on the ol' VR's? I've located just two: 1. Steering head bearing 2. Drive shaft cover. Any more? Tried looking through the manual, but I could have missed something. Harder to fumble through the electronic copy than a hard copy.

Tried looking through the manual, but I could have missed something. Harder to fumble through the electronic copy than a hard copy. Depends on year. The 1983-1985 had ONE Zerk; on the swing arm (a futile attempt to lube the rear spline). The 1986-1989 had ZERO Zerks. The 1990-1993 had FIVE Zerks; all at the rear suspension links pivot points. None of the Ventures had a steering head bearing grease Zerk from the factory. Some folks did add that Zerk, though.
garyS-NJ Posted March 23, 2016 Author #7 Posted March 23, 2016 So to grease my drive shafts (every 20k miles?) I need to remove the shaft? Then that's removing the read wheel and the pumpkin?
frankd Posted March 25, 2016 #8 Posted March 25, 2016 Yep.....pull the back tire, then pull the pumpkin (4 nuts in front of pumpkin), then pull the driveshaft out. Grease the front spline, and reinstall the driveshaft. Sometimes you have problems getting the front spline to go into the female half of the coupling, but leaving the transmission in gear helps and when you can't turn the driveshaft you know it's engaged. Grease up the rear spline with heavy molybendum-disulfide grease. I also put some grease in the pumpkin half of the spline. Some of it is wasted, but this coupling needs grease to keep from wearing out. Then you re-install the pumpkin, but leave the nuts just snug until you get the back tire and rear axle re-installed. Then tighten the pumpkin nuts. On my 83, I grease the rear splines every 10-12,000 miles. By this time the grease on the rear spline is starting to break down. I think 20K is too long.
Venturous Randy Posted March 25, 2016 #9 Posted March 25, 2016 I just greased the splines every time I changed the rear tire. Randy

I guess I got them both then. Must have had a nice PO at some point that added the steering stem zerk. My thumbs did this on a tiny keyboard so cut me some slack!,

Hey @Trader,, sorry I missed this one... As long as you wiped off all the 2nd Gen oils and stuff, cleaned the new pin holder up really well with carb cleaner and then covered it with drain oil from the 1st Gen before you installed the sequencer all the while singing "You And Me Against The World" softly to that 1st Gen you should be ok...
