Volvo EC15B mini - engine removal & injection pump overhaul - plus ......

[Muz]

Hello Jack, and welcome to the forum ... thanks for sharing your dilemma , I'm sure we can help you out

The track motor is just a main relief adjustment and isnt a problem, finding it is though, as Volvo used a variety of valve blocks for these machines, but we'll come to that. Is the pump a Volvo price for service exchange (dont think they do them) or a new part youve been quoted ? .. they are quite simple bits of kit which dont need timed, as they pick up the timing from the cam lobes underneath the pump that drive the plungers up and down, whats busted ? is it the pump plungers on the pump (it pulls out as a single unit) or the cam shaft its self ?

I assume you took the engine out to work on it at a remote location ?

The engine is a Mitsibishi L3 if your looking for parts

Hello All,

I have a Volvo EC15B mini digger/excavator - 2500 hours and in good shape except the performance drizzled off, became intermittent and then finally died whilst doing some trench-work at our place.

Originally I had found Muz's thread on removing the engine from his EC15, so I tried to do the same on mine. My EC15 was stuck at an odd angle with barely enough space to drop the counterweight,plus all the mud. A bit of a nightmare. Armed with Muz's photos of his engine removed and the official parts list from Volvo I managed to remove the engine and drag it into the workshop.
My original message to Muz was this- "There are 3 bolts securing the engine tray to the digger and I can find two of them, but where is the third?"
Muz suggested I start this thread so as to share the struggle!

The parts list clearly shows the easiest bolts to locate and remove, in fact you don't really need a diagram to find them, but I couldn't find the third bolt. I found it after crawling underneath the digger-a tight fit-and found it located on the LHS [from the rear] through an access hole. All 3 bolts can only be removed from underneath the tray.

After that, and disconnecting the obvious umbilicals, the engine lifted out very easily on an engine hoist. It weighs 125 kg dry.

The problem lies within the fuel injection pump. I know this because there the tinkle of bits falling from the pump into the oil sump. I have the sump off now and have retrieved the bits.
If this thread causes any interest or questions I'll add some photos. For various reasons my time repairing the EC15 is limited as it is located at a property that is rented out as a holiday let.
The cost of a new pump is towards £600 plus FAT. I have to try and fix it. One other thing - I bought the digger secondhand in July 2012. It has always tracked weakly on the LHS travel motor. I'll be investigating how to get the hydraulic performance up to scratch and will be asking [nay, begging..] for advice from this forum.

To be continued.
