AQUABLAST – HONDA K-SERIES GEARBOX HOUSING FOR JUST €200! ✨

A clean, uniform satin finish for your aluminium parts β€” without paying for services you don’t need.

The Honda K-series gearbox housing shown in this video is just one example of what we can do. We also treat engine covers, motorcycle parts, automotive components and many other aluminium parts.

πŸ”§ €200 – AQUABLAST ONLY

For a Honda K-series gearbox housing, the basic service includes:

πŸ’¦ AquaBlasting of the housing
🚿 Initial water rinse inside the blasting cabinet

Parts must be supplied dismantled, degreased and ready for blasting, free from heavy dirt, oil, grease, old sealant and other contamination.

Preparation and final cleaning are not included in the €200 price.

✨ WANT THE COMPLETE TREATMENT?

For an additional charge, we can take care of the entire process:

πŸ” Preparation
Removal of old gaskets, O-rings, liquid sealant and other remaining components or heavy contamination.

🧼 Automatic pre-cleaning
Thorough degreasing in a heated basket washer using a dedicated cleaning solution.

πŸ’¦ AquaBlasting
Removal of oxidation and surface contamination, creating a clean, uniform satin finish.

🚿 Initial rinsing
Water rinsing inside the blasting cabinet immediately after treatment.

πŸ”₯ High-pressure final cleaning
A dedicated enclosed cleaning system uses heated water and pressure of up to 140 bar to flush difficult areas, threads, corners and accessible channels, helping remove remaining blasting media.

πŸ’¨ Drying
Compressed-air drying inside the cleaning chamber.

πŸ”Ž Final inspection
Checking the cleanliness and finish of the treated parts.

πŸ›‘οΈ Impregnation & surface protection
Optional protection to help preserve the finish and reduce oxidation.

βœ… Choose the service that suits your needs. From AquaBlast only to complete preparation, cleaning and surface protection.

πŸ“© Send us photos of your parts and we’ll provide a quotation based on their size, condition and the work required.

πŸ”§ Nissan 350Z gearbox – full rebuild + AquaBlast ✨

This one turned out to be a much bigger job than expected.

βš™οΈ The gearbox was completely inspected, measured and rebuilt.
A large number of parts had to be replaced because the condition was worse than it first looked.

πŸ‡―πŸ‡΅ Many of the parts were specially sourced from Japan, including parts that are no longer available in Europe.
Some components even had to be specially produced in Japan, while a few others were extremely difficult to find and had to be sourced elsewhere.

πŸ“¦ It took some serious searching and organizing, but in the end everything was found, checked and assembled according to specification.

✨ The gearbox housing also received a complete AquaBlast treatment.

Really happy I could help with this project and bring this gearbox back to the condition it should be in.

More interesting projects are already on the way πŸ‘Œ
If you like seeing this kind of work, leave a like or comment so I know I should post more of it.

A good example of what Aqua Blasting is capable of. πŸ”§πŸ’¦

These gearbox gears were first thoroughly degreased and cleaned in a parts washer.

After that, the deeper corrosion and oxidation were clearly visible.

Using Aqua Blasting, the corrosion was removed while the surface was also cleaned, lightly smoothed and refined at the same time.

The result shows very well how Aqua Blasting can restore heavily contaminated and corroded metal parts and bring back a much cleaner, more even surface.

Stripped or damaged threads in a gearbox housing don’t automatically mean the housing needs to be replaced. πŸ”§

Professional thread repair is also one of the services I offer during gearbox repairs and rebuilds.

The damaged thread is carefully restored so the connection is strong, reliable and can be tightened correctly to the specified torque again.

βœ… Professional thread repair
βœ… During gearbox repair or rebuild
βœ… Strong and durable solution
βœ… Precise and clean workmanship

πŸ”§ Honda S2000 rear differential rebuild with an MFactory L*D βš™οΈ

Rear differentials require a lot of precision, which is exactly why I enjoy rebuilding them. 🎯

To do this job properly, you need more than just the Honda workshop manual, because some important details are not described there. πŸ“–

⏱️ In just 90 seconds, you can see the complete rebuild β€” a job that actually takes many hours of careful and precise work.

I hope you enjoy the video! πŸ™Œ
If you like this kind of content, please leave a like πŸ‘ so I know that people enjoy seeing the work I do.
