I apologize if this topic has already been covered, but if so I couldn't find it. I'm getting ready to go back together with the injector pump that was frozen and wanted to confirm the oil level. See photo. I see the oil fill and oil drain plugs, but for the life of me can't find where the oil level is checked. I've found where people have talked about a plug you remove to check the level, but I don't see that anywhere.

Also, if anyone knows where I can find parts to the Motorpal injector directly from the manufacturer, I would appreciate contact info. Google has failed me in this endeavor. There is a local Zetor dealer but I hesitate to contact them if I can keep from it. I've had issues getting parts in a timely manner and costs seem much higher to what I can find online for other items.

Any help would be appreciated!

pump that was frozen
I'm guessing you mean seized, not frozen as in ice from cold temperatures. You are using an Americanisms again.

but for the life of me can't find where the oil level is checked
On your 10145, the injector pump is oiled by the engine. You don't have an oil level in it to check. I sell new Zetor parts, but as far as injector pump, I would bring them to a diesel fitter shop to get a trained professional to look at them. I have some old pump here that are scrapped. That's the pipe in red I drew is feeding your pump oil from the engine.fgyuiuygtfd.PNG

Good to know; thanks. The oil fill and drain plug through me off. When I drained it only diesel came out; no oil. I’ll make sure that line is clear.

guessing you mean seized
Yes another dadgum Texan colloquialism. We’ll get it straight one day.

One follow up question; does the pump need to be prefilled with motor oil after it is reassembled before starting the engine? I would think this is prudent to reduce wear on the pump but leaves me wondering how much is required since I can’t check it.
 
The oil filter cartridge or filter bell should be filled with oil before installation. This is obviously not possible with a centrifuge.

You could first let the starter motor turn over the engine without starting it. This will prime the engine oil. Do this twice for 5 seconds each, with a short pause, and then start it at idle.

This will prime the engine oil to all lubrication points, and you shouldn't experience dry running.

Your pump is different to the ones on my 8111's because you have a turbo injector pump. My one the pipe coming from the engine is connected to the pump lower down on the side.

There will be plenty of air in the fuel lines currently so turning the motor over prior to it starting will not be an issue. Had to remove a fuel line to get the engine to turn off due to the throttle being seized (frozen ;)). I appreciate your insights. I guess the oil drains back into the engine block from the injector pump via the connection at the block?

The note on the injector stating to change the injector oil every 200 hours is very confusing since it is self oiled. This must have been a transition model somewhere between when self oiling was normal and when it had its own oil supply.
