    Rear suspension linkage overhaul

    I have just commenced an overhaul of my rear suspension linkages which is recommended to be carried out every 20,000 miles. I always do mine yearly, along with a few other jobs such as lubricating the well documented rear brake and gear lever pivot bolts. My yearly mileage is around 13,000, so I always get there ahead of time. Last year I found the front yoke bearing and pin to be very badly corroded and the pin was badly worn. The bearing was seized and dry of lubricant. I replaced the worn parts together with all 10 oil seals. None of the other pins or bearings in the linkage were worn. I have just found the front sleeve and pin to be badly corroded again, so both will have to be replaced. The bike never sees salt and I have never used a power washer on it. My only conclusion is that heat from the exhaust and engine warms up the front bearing and possibly melts the grease out of the bearing. Just want other members to be aware and would welcome any reports of similar problems. Incidentally, there is a small aluminium sleeve 20mm diameter x 25mm long with a 12mm hole which goes in the right side frame lug for the front yoke bolt and this is listed at 45 plus vat, making it 54. That's a rip off I reckon, unless the decimal point is in the wrong place. Mine had a little corrosion and was tight in the lug, making it hard to get out so I made one from stainless steel

    Wonder what type of grease is used and could a high temperature grease be substituted like wheel bearing grease specifically for disc brake systems where the temperatures are elevated.

    I used high temperature grease, so I thought I would have been okay.

    I had the same issue but much worse.  The bike was 3 years old, had done 17000 miles and been serviced by Triumph at the required intervals.

    The Drag Link (Y piece) failed - one arm snapped!  (see image below)

     I requested Triumph paid for the replacement, as it had not yet done 20K for the schedule lubrication, but they blamed everything else - salt, powerwash etc and would not cough up.

    234 repair.

    I have since been lubricating the link at least every year with high temperature grease.

    I remember another member posting about failure of that part,.....so at least two owners have experienced this. :005:

    What's a Zerk? Another term for a grease nipple I guess??

    Removing and re greasing a bolt isn't such a big deal in my eyes, if only the people on the factory floor had inserted said bolt the correct way round in the first place.  :233:
