I’ve been noticing that I sometimes have a little difficulty shifting into 1st and 2nd. Spraying grease on the exposed wear points on linkage under the van makes the difficult shifting go away for a while, so even I got the message that it needed some attention This diagram shows the linkage, my van has neither the shift linkage protective tube, nor the rubber boots protecting the rear bushing.
Another difference is that as well as the roll pin that secures the horizontal linkage to the vertical link right at the transmission, my van also has a horizontal bolt and nut securing the two. The linkage at the rear comes off pretty easily, except that the skid rails on the syncro does restrict access to some nuts and bolts. The roll pin is tapped out with hammer and small drift from the inside of the vertical link, that link drops from the ball link which is attached (13 mm nut) to the shaft coming out of the transmission. On the bench, the manky, dirty bunch.
Then all cleaned up.
The brown ovoid shaped bushing was packed inside with a mixture of old grease and grit, took a few minutes to get that clean. The roll pin is worn, I think I should get a new one ( have a spare bit of linkage so I can get the right size at the shop).
Then it’s grease them up and put it all back into the van, with a spritz of Fluid Film. Not really happy about the rubber boot that covers the transmission selector shaft. It does grab onto a ridge on transmission, but outboard end of it doesn’t seem to attach to anything. You can see a glint of exposed shaft in the pic below.
Shot of the linkage U-joint, which seems/feels pretty good, and the forward bushing which takes a bit more effort to get to.
No road test done to see if the shifting has improved, but parked, it goes into all gears nicely.
While I was in the mood, I had a look at the linkage/joint right under the gear shift lever. You know, hidden by that box above the spare tire. I had been reading this thread on the Samba and was curious.
The plastic ears are in place, and not too badly worn. Trust me, you can’t really see because to the grease.
Cleaned off the old grease and put new stuff on.
