    DIY - Kartboy Endlink Bushing Changeover from Polyurethane to Delrin.

    tools u will need..
    17 socket
    17 spanner
    Grease
    cloth
    jack + Jack stands


    please be aware of the dangers involved in DIY's involving jacking up your car etc. Don't depend on scissors jacks for support as this jack may fall.

    The bushings in question were replaced because the Kartboy bushings have a tendency of bursting every few thousand km. [this does not include racing/extreme driving.] The material used is a stick of delrin, bought from a machine shop supply in arima. Bought one this week and had it cut in a machine shop in south, and i supplied the original bushing. please be aware that the outer diameter when cutting must be almost same as the space for it to fit. Delrin does not bend/flex like polyurethane. Care must be taken with the dimensions. you may end up having to tap in a few sides of bushing to get them in...> but do not force it. have it ground down a bit more, from the machine shop, and then attempt re installing. It is my advice to give the machine shop one endlink frame for them to get the measurements correct.

    1 jack up car remove wheels.

    2 when wheels are removed, take the 17 socket and ratchet an begin removing the endlink. Point to note, u should jack up BOTH SIDES of the car(entire front) to avoid twisting of the sway bar. This would cause eneven height and difficulty in installing and removing the endlink bolts.

    3 when endlinks are removed, clean them and begin installing the new bushings.

    Good write up man, didnt even think about replacing the endlink bushings. ALso should include the word endlink in the title, i found myself reading through trying to figure out which bushing was being replaced.

    Ola, buy the stick from lo tech in arima. u will have to get 2 and 1/4 inch width, and about one inch ( a little under ) is required to shave one. so calculate n see how much u want. when u get it, well. ent u hav to come get sum from me?
    so. either i give u a sample, and u get it made by a machine shop, or u let me get it cut for u.
