Well, actually - for a 1978 model - my backhoe is in pretty good shape.
This first post will be a bit overwhelming I fear, but this all needs to be documented.
Next up is a video showing the leak...
Now, diagnosis (?) and early plan as to how am I going to tackle this...
First steps: Where am I going to work on this, since it doesn't look to be a quick fix?
You need to cycle the glow plugs longer before cranking >> I go 1.5 minutes but up to 2.5 minutes if its really cold and you can hold them on after it fires until it is firing evenly. Behind that tranny cover are two hydraulic pumps (tandem mounted) your leak is likely the hose or fitting leaving the pump outlet port.
ReplyDeleteThanks! Yes, I found the starting guidance in a manual I got online later. The manual specified a much longer glow plug cycle than I had guessed. I think they specified 1-2 mins depending on temperature. It starts quite reliably now.
DeleteI haven't got back to working on this beast this year, so far. I am hoping you are right about the hoses! I suspect that will be the cheapest fix, as opposed to replacing a valve or pump.
Coincidentally, I had some work done on my compact farm tractor, a Case-IH Farmall-40, by the local dealer and discovered that they not only used to sell this backhoe - but still service them! While I do want to work on this machine myself, I also need to get some earthmoving work done (preferably sooner than later!) So, I have arranged for them to work on this backhoe for me. I am sure they will find many issues to address and I will have to make some decisions as to how far to "fix it".
Again, thanks for the comment!
