642 engine Rebuild--Ford Industrial 1.6l

[bfingar]

Hi all: I am new to the forum, and I am planning to rebuild the engine on my 642 next fall/winter. Has anyone here done it? Any problems, things to note/look for or parts availability issues? I use the machine for personal use and perform all my own maintenance and repairs. I have been trying to find a site like this for years. Thanks Bernie

I have never done it before, i have only re-built a 743 engine, 1.7l kubota diesel.
With your Ford engine being petrol, it will be easier than a diesel, no injection to worry about or setting piston to head clearance.
If you don't have a service manual or workshop manual that covers details on the engine, i suggest you get yourself one. These manuals detail everything you need to know and where pieces go and what tension bolts should be at.
Just how far are you going to go? a COMPLETE rebuilt? or just the bottom end or cylinder head.
What are the problems with it at the moment? why do you feel it needs a re-build? have you done a compression test?
Sorry for all the questions, it will just help with suggestions on what you should do next.

Hi Tazza:
Thanks for the reply.
I have owned the 642 for several years now. It had 4600+ hours on the hour meter when I bought it, but the hour meter was not working. I fixed the hour meter recently and have performed a few repairs---a hose, carb, steering linkage/foot pedal linkage bushings and fixed a couple of leaks. Generally speaking, it is pretty tight and works well.
The compression is good, but the valve guides are worn, and quite frankly, I am wondering how much clearance is on the main bearings. The u-joint between the engine and the pumps is starting to chatter, so I need to repair that, also the engine is leaking oil at the front main and timing chain cover. Generally, I want to do a complete rebuild on the engine in the next year or so for piece of mind.

I see your point.
Well, as far as i know, the ford 1.6l engine they use is an escort engine. Which means you will easily be able to get parts to re-condition it at a good price. Try calling your local engine re-conditioner and see what they want for one. Or you can call and see what they want to machine yours and you buy the parts and assemble it, if you wanted to do it that way.
Either way, you will be sepnding a few $$$ on it, mine cost me 1,500 in parts for my kubota, and i got the machining for free.
Make a few calls and see what you come up with, then you will have a better idea of what to do.
