    4BD1 injection pump leak

    Today I took the Perentie to get a QLD safety cert so I can register the old girl in her new home state. Unfortunately the mechanic I took her to picked up on a minor diesel leak the IP has coming from the throttle control lever. I'd noticed the leak before and tightened the nut on the lever and the leak had stopped, but now that it has returned it may need a proper fix. Unfortunately I can't access the vehicle to take a look until tomorrow and I'd like to go with an idea of how far up the proverbial creek I am and whether I have a paddle.

    Digging through the EMEIs, I've found this paragraph and picture.



    Which tells me there is an oil seal around the throttle control lever shaft; question is, is it installed from outside the pump case or inside? Now I really might be asking too much, but does anyone know the dimensions of that seal?

    from memory both can be changed externally if you are tooled up appropriately and have just the right amount of luck

    All good mate, we missed the bullet luckily. Went to the south of here at the last minute.
    I see Dave has supplied both the part numbers you need. And I can confirm you can change them in situ externally.

    4BD1 injection pump leak

    Seal reseated; thankfully access isn't difficult. It seems to be holding for now but a replacement seal has been ordered just in case. Seems the culprit was the nut holding the throttle plate onto the shaft working loose and the resulting movement of the shaft disturbing the seal. Sorted now.

    Cheers,
    Matt
