Bought an 04 RTV900 missing many parts. Asking for help ID'ing what I need to buy/replace.

[Will.G]

I got this RTV900 as a weekends project. I'm 100% new to mechanic work and everything I know is from the internet. I know I need an air intake box + filters, oil cooler, complete head assembly, injectors, injector lines, and some other odds and ends. The radiator is missing in the photos but I have it. The block was stored with the cylinders exposed and I found a fair bit of water (a few tablespoons-ish) in the oil. The cylinder walls were not too dirty and can turn the crank without issue. I'm also worried about the injector pump as the top was exposed. I plan to keep this project and sell my Gator as the RTV seems to be much higher quality.

Biggest questions:

1: Do I need to tear apart the block and clean everything/replace rings inside it?

2: Do I need a new injector pump or can I tear that apart and clean it?

3: Can I trust Ebay head assemblies?

4: What's the best way to put a parts list together? I don't know everything I'm missing.

Much respect on the project. I am sure many will help. I would look for another project vehicle for parts. Post as you go... Would love to watch

here is a link to kubotabooks.com parts book for a RTV 900 this should help you figure out what is missing. https://www.kubotabooks.com/AutoIndex/index.php?dir=Utility Vehicles/&file=RTV900-EU parts.pdf

I would also recommend downloading a service manual for the RTV 900. https://www.kubotabooks.com/AutoIndex/index.php?dir=Utility Vehicles/&file=RTV 900 WSM.pdf

You need a head the rocker arm assy,push rods and maybe lifters? Injection lines and injectors. Take a magnet to see if the lifters are still in place? Use light sand paper and steel wool polish the top of the block and steell wool the cylinder walls a little. Take out oil drain plug and rinse down with copious diesel and turn the engine. Looks like the bellcrank that controls the tranny throttle and speed lever is missing.

Thanks a lot! I cleaned up the block and cylinder walls and they seem great. I also realized I don't have an air intake manifold and ordered one. I ordered a rocker arm assembly but the three screws don't line up correctly with the head. Is the rocker arm assembly adjustable outward? I only need need 1-2mm for the outer screws to line up.

Sounds like everything moves smoothly. Here is another source for aftermarket RTV 900 parts. If you don't really trust Amazon or Ebay, maybe try this one.
