An interesting fuel contamination issue on Kubota tractors... Tank contaminationAnother Kubota fuel problem

I keep my motorcycle(MC) stored along with my tractor. The gasoline in my MC will sit for 6 months and has never been a problem. Diesel fuel is far more stable and can last considerably longer (in storage). This tractor is over 8 years old and been stored in the exact same manner as ever...

Last autumn I noticed a drop in engine performance / power. I assumed it was a fuel related issue and decided to forgo maintenance until this spring. Comes late March and got the tractor out of storage (eng ran fine at that time) and then replaced the primary and the secondary filters and...

Thank you !

I need to replace this knob as I hit it with my foot last winter and it cracked bitter cold. Can anyone provide a p/n and an online source ? Thanks

Remove the bucket and rent a trailer ...or hire a flat bed ...either way don't play games with the "stealership"...take the tractor to them.

Moly-B Moly platelets have the characteristic of being able to slide across metal surfaces quite easily. This allows metal to rub against metal while being protected by the lubricating properties of moly grease. There are microscopic pores on the surface of all engine parts and the thick gooey...

.. Cyl #1 is the cyl. that closest to the fan. You only need to slightly loosen the inj B-nut. If you remove the line and crank the eng. you risk ingesting air into the pump. Simply loosen the inj. B-nut as you crank the eng. Once you see fuel sputtering out ...then tighten the b-nut. Then...

As for the fuel delivery problem.. Have you verified "positive fuel delivery" to the #1 injector ? With the battery at a full charge... using a 17MM wrench and crack open the #1 B-nut at the injector and then crank the eng. to see if you have fuel sputtering at the B-nut. Then continue with inj...

ok... From reading the manual I had assumed that there were two (2) dip sticks (L&R). There is only one dip-stick and it is located on the (R/H) side of the Front Axle Case.

I'd love to post a photo ...but haven't figured that "How to" just yet.

I would start by looking for a clamp for the capacitor either on the eng. or the generator. Weather this capacitor belongs to this Gen set ...I don't know.

GR2120 Front Axle Case "Dipstick" ... Where is it ? I'm reviewing the procedure on servicing the front axle case (oil change). The operators manual (Pg. 67) shows a dipstick ...damned if I can find it !!! What am I missing ???

Kubota GR2120 filter Cross Reference: I come to learn that the GR series filters are manufactured by "Donaldson". Here is a list of the GR series filter to Donaldson: Kubota Fuel Filter: 12581-43012 / P550012 Trans filter: HHK20-36990 / P550227 Eng oil filter: HH150-32430 /P502067 Air...

Dave, I'm very happy with both that Ventrac tractor and the Kubota engine. In in dead of winter (Maine) @ -12 F The engine is slow to start. As in any extreme environment it can quickly take a toll on any equipment. It's very hard on the starter motor as well as engine internals. As far as the...

I needed to up load a few more photos...

I own a Ventrac tractor which I use year round. This tractor has a Kubota D-902 engine. I wanted a block heater but not the type the attaches to the lower radiator hose..I want a "Block Heater".

I have a question concerning the size of the freeze plugs. I have a Ventrac Tractor its engine is a Kubota D-902 diesel . I need to know the diameter of the freeze plugs. I want to install an engine block heater and I want to verify that I am ordering the correct diameter unit. I suspect the...
