1690t injection pump

Post by GeoffDEAL » Sat Apr 04, 2020 12:31 am

Was checking out an apparent miss cracked open injector nuts and found back one was getting no fuel, removed cover on injection pump and found spring on that element was loose not broken and therefore not pumping, would think there is a problem with the roller lifter- its pin -or the operating cam, has anyone had this happen and your thoughts thanks.

Would it be worth getting it rebuilt --no diesel in oil --so not worn out, or replace it, thoughts from others that have had pump problems appreciated.

Look at the cost of a rebuild and the cost of finding and buying a 2nd hand one in an unknown condition which also might need to be rebuilt.

Hi Geoff, do you have a picture of the loose bit? I have had my 1694 pump apart at the governor end to replace the governor and camshaft, I have a few bits laying around.

Hi jazo the spring on the faulty piston is just loose and sitting there which to me indicates there is a problem with the lifter- the roller -its pin or the main cam lobe is worn out on that cylinder so not an easy fix. cheers Geoff
