OSSA suspension linkage

Yes, Explorer and TR are the same. 

 The grease fittings are there- I used flush ones that use a ‘needle’ type end. Three of them could have ‘regular’ zerk fittings, but the one for the main pin does not really have enough room.

Before I sell any, I want to make sure everything is just right. I have made some little mods.  I wanted to keep as thick as possible for strength, but also need to have clearance for the Ohlins or the Olle dampers since the springs are a bit different in size.

Ok thanks. This suspension set up using these brass push fit bushings do they have any lateral movement because when my bike is on its stand i can slightly lift the wheel or the rear of the swing arm and i can feel a tiny amount of lateral movement. I have replaced the bushings and greased everything an bought a new pin from Birketts and there is definite movement from the pin area. Ta

Original is steel w/teflon coating. This has the same except middle ‘main’pin that is now needle bearing. 

When I have final fitting done I will let you know. I have to make another bit of a change to clear Ohlins damper- the Ollé is smaller diameter. But that is what initial testing is all about.

I have the slightly modified version installed. I very slightly changed some tolerances (the place making them follows better than I expected). And had to change the ‘dogbone’ to similar thickness to stock, although a bit taller. (Would not clear Olins). 

I really like the almost flush grease fittings.  They work really well and easier to access. Just require a very inexpensive adapter. 

Works great!

Nice. Is there any play in this set up or from the factory. When my bike is on the stand with the suspension relaxed if i go to lift the bike back off the stand using  the wheel the wheel  will slightly lift before the bike does. I have pinpointed the slack and replaced the pin and all the bushes but there is still play in that area. Is there play from new with the factory setup. Thank you. 

[lotus54]

No play in this setup.  But certainly if any pins/bushings/bolts worn it will have play. 

I would have liked to use needle bearings for front pivot, but doesn’t look like enough room. But the most stressed one is the middle one (I think) and that is now needle bearings. 

 

Also check the bottom damper bushing

Hello Mark. All new parts and never been ridden. The damper bush is tight. That is why i asked about you Ti set up and maybe the tolerance is better than what i have. 

[lotus54]

Those are the places to check (and upper damper).  Can you see where the play is? 

  This does have very good tolerances.  .0005”

Yes i did mention it in an earlier post. I can feel that the play is in the 20mm pin which is new and the bushes are new.

OK, I forgot that. 

  There is no play in the 20 mm pin (which is smaller now, since it has needle bearings, but much stronger material)

Ok Mark. Ta.
