Cleanliness is definitely helpful for identifying leaks. I use U.V. dye and a black light for pinpointing leaks quickly when you have a big mess to deal with once you narrow down the system that is leaking. In areas where oil is spraying around, at times I have used cardboard to narrow down the...

I am not familiar with repairing a spool valve on these machines but have considerable experience dealing with rusty parts you need to save. This might be a good place to try Evaporust{a low Ph. solution}, it will eliminate only the rust and not harm the parent material. Harbor Freight carries...

Scott thanks for this very comprehensive thread. I would like to add that when I did my water pump I used a NAPA # 41143 that my counter guy tells me is going to be re-released soon. That number crossed to an Aisin WPM-006 that i got off Amazon as a spare and appears to be correct. Currently...

Does adding a little choke improve it when it starts bogging?

Thank you for posting this photo. It is great to see it done this way to get the Best access possible to the chain case. I had not considered the loader arm as a lift point until I see it chained down. Simple and brilliant, Thank you!

Apologies if I am re-posting this a second time, I was redirected to log in when posting the 1st attempt. I also have the 4G32 in my 742B, the oil pressure switch is located in the base of the oil filter at the 11 o'clock position when viewed from the rear of the machine. It breaks out of the...

I also have the 4G32 in my 742B, the oil pressure switch is on the backside of the oil filter housing at the 11 o'clock position when viewed from behind the machine looking fwd. The wire/connector to it breaks out of the harness with some wires for the alternator also. I can see where it could...

I replaced the lift assist cylinders on my 742B and still find it very heavy to lift. Make sure the hinges are not rusted up.

Just saw the message for more details, glad to answer what I can. What info would you like? My machine would not go straight with the sticks all the way forward, I reversed the motors and the problem followed the weak motor and went to the other side. Resealing the motors fixed my problem but if...

A buddy with an old 743 told me his machine blew the engine oil dipstick out and found that bugs had moved into his road draft tube and clogged it. This would not cause smoking as you described but worth checking to be sure it is clear. I believe it exits out the rear floor of the engine...

Mine just required adjustment when i got it and I would consider it essential. It will cause the levers to buck when applied and is strong enough to keep the machine from moving.

Many excellent suggestions here, most of them I learned the hard way. I have the same machine and it was in pretty tough shape when I got it but picked through it mechanically to the point it was squared away and deserving of fresh paint. It is a great machine and i use it for plowing my parking...

It sounds like a piston/cylinder problem more than a valve issue, I am not a diesel expert by any means, I am just not following how a leaking valve would allow that pressure to end up in the crankcase...it could get into the cooling system for sure. A machine shop can absolutely check the head...

Glad you got the engine performance sorted out, it will be interesting to hear what you find out with the pump.

Keep it simple, if the base timing spec is 0 degrees, set it to 0 degrees and observe what the vacuum gauge reads for manifold vacuum at that point. No need to concern yourself with the vacuum advance or mechanical advance at that point. If you are using the pcv hose your gauge should not be...
