    Drag/Drop link bearings (sizes)

    I have put this up here for information to all if you start replacing these bearings as it seems to be  secret (or wrong) across the web re the bearing sizes as the numbers stated on parts diagrams are silent or differ to what is actually on my bike!

    I had a busy day yesterday extracting the seized sleeve & bearings at the bottom of the shock (i had to take the shock off too)....at its recent service this was the only bit they couldn't do as it was seized, and as i have done the same on my old Sprint I knew the time/tears/blood it would take to sort this one! 

    It was a bit of shock  :745: when i checked the sizes at triumph as they don't seem to tally with the parts lists.   e.g. https://www.fowlersparts.co.uk/parts/5597542/trophy-1215/rear-suspension-unit-linkage
    So the bottom of the shock has the bearing through the shock of 20x26x20 (#T2057502), and then 2x 20x26x16 on either side that go through the bottom of the drag link.  Well this is what i took out!
    When you look at the parts diagram, it lists the latter two (#T3800199) as 202620..this is not the same size i took out as you can see above (they didn't have any on stock at Fowlers for me to clarify).

    So just to clarify these are the sizes you need to replace the following parts:
    T2057502 (1x through bottom of shock)  20x26x20
    T3800199 (2x either side of above in drag link)  20x26x16  (NOT 202620 as on diag)
    T3800060 (1x on single end of drag link under engine)  20x26x20

    if you need them, the others are the 2x through the swingarm at the top of the drop links  20x26x26

    Each bearing will need a pair of 20x26x4mm seals, so if you are doing the lot like me, then you need 10x bearing seals for a proper job.

    Now I am not going to replace these from a triumph supplier as they are at stupid prices (they wanted 110.85 just for bearings and seals which are branded KOYO by the way).  So the only thing i picked up last night from them was the replacement sleeve to fit through the lower shock.
    If you get your supplies from a local bearing supplier or online then its about 28 for all the bearings and seals (NTN branded)

    I had some spare 20x26x20 and seals knocking around and thought that was all i needed...but NO!

    If anyone knows anything else, or I have anything wrong, then let me know  :001:

    Ive stripped mine a couple of times for maintenance  and replaced some of the bearings and all of the seals. Like you, I used a local bearing supplier and got the lot for a fifth of the dealer prices. I just sourced the sizes from World of Triumph and ordered them from the bearing supplier. They all fit straight in.
    I made up some drifts to make the job easy if you need to borrow them or if you have machining facilities I could send a picture

    thanks 1675...i have them out now.....it didnt help that i had to get the shock off in the end so that i could use some brute force to get the sleeve out of the bottom

    i just checked on world of triumph and they seem to have listed the sizes correctly on their diagrams, it may only be Fowlups.  Adding WoT to my favourites now!

    still cant get over the one in the bottom of the shock where triumph want 52.88 for the "bearing kit"....but it only costs 8 for the same 2xseals and 1 bearing elsewhere

    If you think that is bad, check out the price of a front and rear tyre on WoT. Make sure you are sitting down. Someone is having a laugh here and I think it is at my expense!

    Could you post that picture/sizes of the drifts you made here?

    I don't need them now, just thinking of the future, would be handy info to have. :002:

    Proceed with caution. Do NOT use caged type bearing. ONLY use FULL COMPLIMENT type with full amount of needle rollers. Caged type have only 1/2 the load capacity of full compliment.  Very important on a heavy bike like a trophy.
    Triumph look at costs very closely in production so for them to fit expensive full compliment bearings there must be a reason, your life!!!!
    e.g. HK2020 is caged bearing. HN2020 is full compliment bearing.

    btw WoT charge about 5% more for parts than retail (any other triumph dealer).
    Jack Lilley even offer discount to most clubs e.g. TOMCC and HTOC.

    Normally the cost of most replacement parts from a dealer is more than 5%,.......if these bearings are a 'bit special' shall we say, why haven't Triumph dealers marked them up even higher??
