250R ProLink Bushings

[wonderboy]

Does anyone have a source or a solution for replacement bushings for the pro-link arms on the 85/86 250R? I just got the rebuilt shock installed on my brothers machine, torqued the pivot bolts, and there is a ton of slop in the bushings at the pivot where the two arms meet at the lower shock mount.

I need bushing #5 in the diagram.

Searches only seem to bring up the swingarm pivot bearings...

Does the Pivot Works not come with that in the kit(?)

PWSAK-H15-020 kit

H-BE-002 is what you are looking for(?)

Searches only seem to bring up the swingarm pivot bearings...Pivot works used to have a kit for the linkage bushings but EVERYONE is out of stock everywhere and some are tellimg me they don't know if they'll ever make any more. PW website says "call for availability" so I was going to next week to see what the deal was. Hopefully they'll still make the kit but it ain't looking good. Been out of stock since December.

PWLK-H23-020 was the kit number I think. The kit had all the bushings and the seal set as well and was about $65 retail

PWSAK is swingarm bearing kit
PWLK is linkage arm kit

Thanks ironchop for the part numbers! So everything on-line seems to be sold out or not stocked. I luckily found a shop near me that actually has one in stock! Thanks again for the info.

Well, I've got good news and I've got bad news.

Good news (for me): the local shop had the Pivot Works kit on their shelf and I got it.
Bad news: the didn't have any more.

I called Pivot Works to see about getting more directly from them. The guy on the line told me that this is discontinued and that they are out of stock at their facility. :(

Would Delrin bushings work and hold up.Just a thought.

Well, I tried using this bushing kit, but something isn't right.

The kit is listed as for a TRX250R, and I assumed that this is what is correct for the ATC250R. The two smaller bushings that go just outside of the lower shock mount aren't right. These are the ones on mine that are worn out. The OD of the bushing is too large for the arm, and the ID for the bolt is too large.

So, is this something where I can substitute the Quad Prolink parts (the actual links) in place of the ATC version? Are they even supposed to be different? Kinda bummed out that I still have a sloppy linkage setup.

[wonderboy]

Well, I guess I kinda figured out my own answer by searching the part numbers on the Honda parts diagrams.

https://www.cyclepartsnation.com/oemparts/a/hon/506ba973f870023420a21222/cushion-arm

Only bushing #2 and #6 are common between the two machines. #5 and #3 are unique.

If anyone knows if I can replace the entire links from the ATC with the Quad versions, let me know.

This isn't good cuz I just ordered that set too from overseas for quite a bit more. The guy who gave me the PW part number never said anything about the two arms being different in that area for the 86 ATC and the 86 TRX. He's had a shop for three decades and said the 86 TRX and ATC were the same shock except reservoir which can't possibly be true because that shock bolt must be a different size between the two models if that set won't work with your 85 in both bushing ID and OD. OD I could see possibly different but they supposedly used the same size lower shock bolts (though different middle part series number)

The bolt part numbers are as follows according to yours and my OEM sources

ATC is: 90125-HA2-000
BOLT,GREASE (12X110)

TRX is:. 90125-HB9-000
BOLT, GREASE (12X110)

"(12X110)" is the listed bolt size for both machines meaning 12mm shank by 110mm long so something isn't right. That bolt passes thru both #5 and #3 bushings so at least the ID of both bushings should be the same between each other and also be 12mm for both the TRX and ATC models since both have 12mm bolt shanks that are 110mm long. If this is not the case, then that also means the bottom yokes of the 86 TRX and 85-86 ATC shocks are also different ID from each other. I'm going to call him back and ask what's the dealio.

Maybe the 86 bolt is a bigger shank stepped down to 12mm at the threads but that makes no sense because the part numbers are the same for 85 and 86 ATC shock bolts according to both our parts fiches

You got a pic of your shock bolt?

Edit: went out to the garage and got my shock bolt. It's a fatter shank stepped down to a smaller thread....

Also found this thread... pretty sure he's a member here too. Read post #3. That means the info I had was specifically for 86 ATC250R and TRX250R only and not 85 ATC which is unique according to deathman

I'll get some measurements tonight when I get home from work. Thanks for all your input Ironchop!

I'll get some measurements tonight when I get home from work. Thanks for all your input Ironchop!No problem. I'm just sorry you got bad info to begin with. I feel responsible for giving you that part number because I thought they were the same as well. I don't want you to get stuck with a set you can't use and I'm willing to buy it from you to make it right. I'll just have two sets.

I'll wait for someone who truly knows what's up to tell you whether or not using 86 Links would work.

So I dug on-line a bit. Here is what I've found:

The very front and very rear pivots and bolts look the same and the Honda parts diagrams show them all cross referencing each other.

The issue is in the middle, at the lower shock mount where everything comes together. Although the Honda parts diagrams list the dimension otherwise, the info from the other forum and the direct measurment of the Pivot Works kits seems to confirm the key difference: ATC250R uses an M12 lower shock bolt, and the TRX250R uses an M14. The Honda parts diagrams list the lower shock mount bolts on both applications as an M12 x 110. I think it is a typo on the TRX pages and it really is an M14 x 110. The pivot works bushing is definitely larger than it should be for an M12 bolt, and the exact dimensions from their website list the ID as 14.02 mm (confirmed by directly reading the part I had from the kit).

I made a table in excel summarizing the part numbers and information, but work won't let me upload the pictures. I'll upload tonight when I get home.

EDIT: Just read your post Ironchop: No worries!! I'm happy to at least have 1/2 the parts I need for the linkage. Your info wasn't bad at all because I was finding cross references to that kit for ATC's on other sites as well. Honestly, I think pivot works did a poor job with this kit as it is actually missing one of the bushings necessary to do the entire setup (missing one of the bushings for the rear dogbone).

yes, I have a bunch of 85 atc, 86 atc and 86 trx linkage parts. Not sure where they all are, though. 85 and 86 are the same length everything, but the bushings(bottom bolt) and bottom bolt is different, it is much smaller on a 85..... The linkage bushing stayed the same from 86-89 and the bolts, change was 87-89 had a shorter dogbone(also shorter shock and even shorter in 88/89).....but 87 had nearly the same swingarm as a 86(it has different skid plate mounts), that is why there is 85/86 atc/trx skid plate and 87-89 skid plate. The reason why many atc's and trx's have the 85 linkage is because when atc's where stopped, there were tons of 85 and 86 250r's, there were yards filled with just the back section of the frame w/ swingarm.......burguard atv had a enormous pile of them. As the the swingarms broke, many bought these from the atc's has they were very close or the same.......But they aren't, 85 and 86 look the same from the outside, but a closer look shows a different axle, brake carrier, brake hub, sprocket, sprocket bolts, rear shock and linkage setup. Many considered them a "dime-a-dozen" and didn't think of the difference as they saw them as "outlawed atc" parts and saw a huge pile of them, very little thought to see they are totally different. I got first hand info about this from a person who saw burguard's yard and spoke/bought parts from the people who worked there. Last time I talked to him, he was saying "I wish I kept a bunch of those nearly new atc plastics and especially the headlights, they were so cheap and easy to get, you couldn't give them away, now you will pay $1000+ for a mint un-used one".

So basically all he would need to do to use that Pivot Works Rebuild kit is to find and use the '86 model ATC or TRX linkage on his '85 swingarm?
