Replacing the Gear Shift Ball Joint(s)

[Andre]

Took her for a test ride. After having replaced one of the angle (ball) joints of the gearshift lever linkage, I now changed the worn out plastic bushings of the gearshift lever which were also worn. Replaced with PTFE coated metal bushings (14/20x9mm). Snug fit, no more wobbling. With the 2 measures no more clunking when shifting to 2nd and 3rd gear.

Sounds like something worth doing, ill check it out new year. Thanks for advice mate.

After having replaced one of the angle (ball) joints of the gearshift lever linkage (as the rivet type mounting had become loose) I have to adjust the gearshift lever now as I can get my foot only with gymnastics under the lever.

I added the pic from my previous post (one page back) about the angle joint again. The replacement is the M6 in the attached pic. Got it in SS with dust cap. Also added a washer and medium loctite. Also remember that one angle joint is right hand thread and the other is left hand. I still need to source the LH but it has only minor wiggle.

In the German forum are quite a few who have done this. Many needed to do it at relatively low mileage. I think the mileage the original riveted joints and plastic bearing last depends much on how heavy a foot you have.

Little money and effort - big difference

Good result Andre

Thank you.

As I am still not satisfied with gearshifting smoothness I'll do a bit more. Inspired by a German forum where putting in a new SPRING, number 25 in attached pic improved shifting a bit. I will also change numbers 20,21 (2x),24,27 (3x), as the gear shift shaft (17) has a little play. Will report here when the results are in (before season starts).

No bother @grog

That rose joint should be fine. Just double check the dimensions. Front joint is RH, the one attached to the lever is LH. I like the ones I used as they can be taken apart for thorough maintenance.

The first 2 links are stainless steel. Unfortunately two different suppliers as one doesn't have the LH and the other the RH.

RH https://www.ebay.de/itm/M6-VA-Winkelgelenk-DIN-71802-Edelstahl-V2A-Kugelgelenk-Edelstahl-CS-RH-M-6/162654729737?hash=item25defa3609:g:upwAAOSwo8hTrV62 This doesn't come with the seal. It can be obtained from him however. https://www.ebay.de/itm/4-Winkelgelenk-M6-Dichtkappe-Neopren-Dichtung-DIN-71802-M-6-Neu/160914399532?hash=item25773ee12c:g:cr0AAOxyu1FRl0il

LH https://www.ebay.de/itm/Winkelgelenk-Kugelgelenk-CS-LH-DIN-71802-M6-Links-V2A-Edelstahl-mit-Dichkappe/152737530954?hash=item238fddc44a:g:v8gAAOSwxu1Z3JwO

Here are standard (steel/zinc plated) with seal from one supplier.

The bushings I used were a nice find by German-forum member. Simple install. Previously people used bushings made from sintered bronze, had to work them with a reamer to fit. I dont have the dimensions of the sintered ones. But you could orient yourself on these in the link.
Unfortunately they send these only to Germany, for your reference: https://www.ebay.de/itm/2-Gleitlager-1209-12-x-14-20-x-9-mm-wartungsfrei-mit-Bund-/162814339976?

I'll be happy to get these bushings for those interested and ship them. Two of them cost me about 6 € (2€ postage incl.). Larger packs are cheaper (example 10 for about 21€), which would be an option if there are several who want to order together.

Plenty of choices now

Really nice work on your 14

Thank you.

[grog]

would this be ok for gear lever, not a bush but with plenty of grease, should be ok? 20mm outside, 14mm inside x 10mm long. needle roller bearing. https://www.ebay.com.au/itm/HK1410-14mm-x-20mm-x-10mm-Full-Complement-Drawn-Cup-Needle-Roller-Bearing-5pcs/302415285034?hash=item46695b0b2a:g:X~4AAOSwXedZ2rp1

@grog

The dimensions are not correct! Outside diameter needs to be 14mm, inside diameter 12mm. 10mm length would be ok as there is plenty of gap (could even be a little longer, would then just prodrude a little over the notch of the "axle". The 20mm in the bushings I used refer to the outside band. If you use something without a band you would need to make up for this by using appropriate washers (otherwise the lever would slide in and out). Or you could just let the bearings protrude out by the appropriate amount.

Needle bearing is just fine. Know of someone who used them with no issues (were from roller blades)

Sorry, remember now that there was the "small" issue that he had to mill down the pin the lever rotates on, to make it fit the needle bearing.

[grog]

Couldnt find another bearing correct size, just ordered bushes. Had to buy 10 so some spares for anyone in Oz that wants one. Will make sure its correct first.
