Yellow Box Engineering ltd has the capacity to restore oil pumps for the Citroen traction Avant to standards well above their original performance.
We can restore ID/DS19/11D and Perfo pumps.
The restoration work includes:
New oversized gears are fitted. They are individually ground to suit the wear in the pump body.
The original pressure relief valve from the Perfo engine is of poor design and it is not possible to satisfactorily refurbish it and so a new pressure relief valve is fitted – the relief valves in the 11D and ID/DS19 oil pumps are of a more modern design and can be reused.
The drive gear is fitted with the correct end float.
All reconditioned oil pumps are then tested at 1000RPM in oil at a temperature of 60/70⁰C. The results are stamped on the base plate. This testing is completely unique to Yellow Box Engineering on our in-house test rig!
Note: This is an exchange service and additional charges (approx £90) may be made if any parts of the supplied oil pump are not suitable for re-use.
Only the oil pump body with its aluminum pick up is required – i.e. remove the strainer and the pipe connection to the block. Make sure that the conical union, Part No. 451672 is securely fixed in the pump body or wired to it.
