Turbo Repair Services
Repair and Refurbish Turbos of All Makes and Models
One of the most difficult aspects of the job is getting the inside of the turbo housing spotlessly clean.
This also includes all the internal moving parts and parts that are not damaged that can be reused in order to keep costs down. If these parts do show sign of damage, ware and tear, or metal fatigue we will replace them in order to prevent a second turbo failure. Provided the damage to the turbo in the first place was not caused by consequential damage. For example: contaminated oil, low oil pressure, blocked oil feed pipe, or ingestion (when the turbine or compressor wheel is hit by a foreign object).
Ordinary engine degreaser won’t remove the baked on oil and carbon deposits that have collected over the years, but having it “boiled out” in a hot solvent or caustic tank is one sure way to clean it without damaging or eroding the metal or tolerance. The Solvent also opens up all the hard to reach places. Especially the oil feed port holes that lubricate the Bearings and Thrust Bearings that provide a good strong flow of oil.
Damaged Bearing Housing
Bore Seal Repair from where you would normally have an oil leak. We carefully remove the old bore seal that has been damaged by a broken wheel and shaft that damaged the bore seal in order to fit a new bore seal.
Step 1 Machine out damaged Bore Seal from the Center Core to fit the new Cast Iron Bore. Insert to a press fit size.
Step 2 Press fit the new Bore insert into place and machine the inside diameter to precisely fit the new Piston Ring.
Step 3 Machine and fix insert in place with 3 grub screws to keep in place.
We also skim warped exhaust manifolds
We supply new Center Cores
Cast Iron Welding
Why does a Cast Iron Manifold crack
This is a Cast Iron Exhaust Manifold that had a hair line crack in it and has been welded by myself
Cast iron is a difficult material to weld because it is a very rigid material and will crack rather than bend. Unlike like most other metals when it is heated up it will expand and contract when it cools.
Why are cast iron manifold preferred to other metals, that is because it is rigid and maintains it shape to a certain extent when hot, it is easy to machine, and easy to cast into a mold.
The solution to welding Cast Iron is to preheat the entire cast Iron Manifold slowly and evenly with a blowtorch then open the crack with a suitable grinder. Then Weld, and allow the casting to cool slowly and evenly in a bucket of sand.
