I overlooked two items, I am in need of upper shock mount spacers, part #92027-1871. Anyone willing to part with a set?

I found them!!!!

Still looking for the top shock mount spacers. Thought I found them, then realized they were not it.

Do you have the seals?

If you cant get the spacers, you can have some made out of chromoly...oops, I meant delrin.

[tecaterob]

Sorry man, I looked today and couldn't find any extra one. I thought I had some...

Thanks for looking, I was able to order one, so maybe I will get lucky and find another. Otherwise, I will have it made.

I'm starting to realize I still have some small items that I need. Along with a a few large items!

*EDIT- IMHO*

These spacers should be repopped, I know a few guys looking for them or will need them, but with so many guys switching to Delrin I don't think it would be worth the time and/or money.

Plus if you switch to a Delrin set-up on the lower shock end you eliminate the pounded out or smashed shock eyelet or worse shock body breakage, not to mention the shock kissing the swing arm.

Kawasaki/Kayaba really should have known better.

Heim= Not good for shock eyelets.

Rubber donut= Not good for shock eyelets.

phantomtracer, the photo below is from a 1985 CR250, and from what I can see, every pivot uses either a spherical bearing or needle bearing or a bushing and a collar . . Strangely enough, I don't see one single elastomeric bushing . . This is also the case with the swing arm pivot . . I guess Honda and Showa "really should have known better" but apparently they didn't get the "memo" from their "engineer" . . I sure hope they are doing a better job nowadays.

Also, there is a very good reason why mfg's of QUALITY bikes and Formula 1 cars do NOT use Delrin for bushings, however, typically only an engineer would know why that is.

oops....doesn't look like Yamaha got that memo either since they too use bearings in their shock eyes on their 1985 and 1986 YTZ250 3 wheelers, but perhaps it's because these are actual high performance vehicles?

Was able to find these after like 2 minutes of looking because I have owned 4.5 tecates and 3 86 KX250s.

I still have your address Phil. I can send you one and help instead of sitting around and being a troll.

Yep, exactly. I got mine with the stock bore and piston still in it and a couple linkage pins already had cracks. Great stuff. Wanna talk KTM style shock links? I don't unless its to about how fast they wear out, what a PITA they are to change and how there are no lubrication provisions which might make them last forever. How can a helm joint hold lubrication? The shape alone sheds grease and there's no way to seal it. Over 10,000 miles on the swing arm bearings (still perfect) and I'm on the third lower bearing and second upper bearing in the past 6,000 miles.

Carry on.

Nico, have you tried this kit?, I have heard good things about them from some big and or fast guys.

Back to the Tecate- Yeah, those heims get pounded flat pretty good and they lose lube like crazy.

On the bottom side of the shock the rubber bushing is just to soft, even a brand new OEM replacement is soft and they only get softer. Unfortunately I have thrown out a few Tecate shock bodies that have been damaged one was from topping out, one from hitting the bracket so hard it smashed/ovalized the eyelet 3/8", one it hit so hard it broke the shock body on both sides of the eyelet and the last one cracked in half at the eyelet, on that one I cut a mount off a old WP shock and had my buddy who welds gas tanker trailers up for a living and has the nickname "Roll of Coins" weld it, but the aluminum has a lot of impurities and is very difficult to weld properly so I stopped fixing them.

[nd4speed]

So that spacer is called a "heim"? and thats what gets pounded flat? I have one that looks like it is sorted smooshed a little on the large OD side. Maybe they are soft on purpose as not to damage more important things like the shock body? So only new ones ensure a seal to keep in grease. Well that is a bummer. If someone was to remake them proper I guess they should hardness test the metal and use appropriate materials? r just use something softer and easy like Delrin and replace more often?

Guess the shock was made to kinda float around on the bolts? Guess this is why this area is usually neglected and not maintained enough on a lot of bikes. I am no exception. I send you one of those shocks with body damage, but I bought it that way for parts. I wondered WTF happened to them.

Um, in the parts swap thread "upper shock spherical bearing can be replaced with a much cheaper neeled bearing. bearing number NA4900 UU $5 off ebay. you just have to use the stock bearing spacers and seals. fits perfect. will also fit the 84-85 t3 and the t4's"

Is this a bad idea to use needle bearing instead of spherical bearing? Probably since it not engineered that way.

[onformula1]

The heim is in a steel case behind the spacer, it is all pressed in and has a c-clip to hold it.

Those spacers are plated, most of the ones I have seen have the plating worn off and will have wear marks on the OD of the spacer, some fast and/or bigger guys will pound them slightly oval, a blown shock can also to the same thing.

If you were to replace them with delrin or similar material you could replace all the pieces, you could also run a steel sleeve in the center as well.
