My comment is a general one. Engines designed for today's emission sensitive environment are designed to run hot relative to engines designed 10 years ago. Steps are taken in the engine design to get the catalytic converter or the diesel equivalent up to "operating" temp asap. One of these...

I respectfully disagree with your assessment of your mechanic. He may have strong skill with one type of vehicle but not small tractors. When you said initially he replaced the clutch, that can mean many things. Do you have an invoice showing parts bought? Do you have any photos of parts being...

The first place to look for wiring diagrams for older B's is in the operators' manual not the WSM. This is the wire color table. The two blue wires come from the dynamo and they are interchangeable. If this is still confusing ask more questions. Dave

This should put you on the right track. Dave

Suggest you use the attached DENSO starting circuit test procedure. Often trouble point is attachment of ground cable to tractor frame. Dave

Looking on Kubota.ca web site I see the following for the oil switch Messicks web site Messicks and Coleman's web site will have same info. After entering model, look in engine section for oil switch. Dave

Water is a component of all antifreezes (or most). If you have concerns about incompatibility why not use lots of water to try and flush the original coolant out. When doing the final refill with the proper coolant, use an un premixed coolant so you can adjust the % of water in the final mix to...

Since no one else has commented I offer the following educated guess. The HST pedal linkage has a damper which is another way of describing a shock absorber. Its purpose is to limit abrupt pedal movements. If its internal valves start to fail it would affect the operation of the HST pedal. Look...

I learned something, Thanks. No wonder it is falling apart :) Dave

Is it possible the model of your zero turn is posted wrong? I am only seeing ZD326 units. I am going to continue with my assumption being ZD326. Kubota has a service bulletin, previously posted by another member, which I have saved and will attach to my post. The bulletin states: This may...

Just connect the two lines from the block to the loader valve together. To the block it will seem like the loader valve is seeing flow but not being asked to produce pressure. If your loader valve has 7 lines it means the loader valve has power beyond to supply the 3 pt hitch. During your trial...

Adjust feedback rod. The feedback linkage should limit how high the upper lift arm can go so as to not keep the relief valve working. Dave

Kubota does not make glow plugs. Companies like NGK, Bosch and Beru are a major reputable suppliers. Try doing some searching. Different brands will be present in various markets. Companies like Coleman Equipment would sell glow plugs by NGK Dave

My comments are from looking at the WSM not from personal knowledge. I see two places where the clutch pedal free play can be adjusted but you are only mentioning the cable. Dave

I had saved this info from a previous post by I think whitetiger: Loader bucket area twisted. I got my fel in a bind today with my pallet forks on. I think one fork pushed that sides hyd cylinder in putting it shorter by about 1 1/2 in. Is this possible or did I bend the rod. There is no...

I have had luck looking on the Briggs and Stratton web site for info and manuals. Briggs You will need to find the Briggs info on your engine. Dave

I agree with North Idaho Wolfman's advice to you re injectors. I would take one step first since you are buying fuel from small gas stations. Drain the tank and refill from fuel from a large truck stop, Dave

Could you please provide a more detailed history. Is this tractor new to you of have you had it for a long time? How many hours on engine? Did this condition happen suddenly or slowly over time. Has any work been done on the upper part of the engine where cylinder heat and injectors were...

These pages from the WSM will help you determine where the problem lies. Dave

If you know nothing about diesels at least get the free workshop manual at this link. WSM I think you will also find an operators manual at the same location. These old engines need a lot of glow plug pre heating time. Up to a minute. From your video I think you do not heat enough! You may have...
