HPFP Strip, Clean & Autotech Rebuild (Image Heavy)
« on: January 23, 2010, 10:00:53 pm »
I have decided to go stage 2+, the downpipe is organised the only thing left to sort out was th HPFP. KRL from here organised a group buy for the Autotech Internals on the mk5 golf gti forum so picked them up for £246.00 Cheers KRL Hoping to see the internals through the door in a couple of weeks.

I managed to pick a HPFP from ebay for only £100 delivered, it was removed from an S3 engine with only 1000 miles (the engine had suffered from oil starvation as the oil pump chain snapped): link - http://cgi.ebay.co.uk/Audi-S3-2-0T-Petrol-Engine_W0QQitemZ380198697573QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item58859bba65



Decided to start the strip and clean of the pump, as this is a spare pump it allowed me to spend plenty of time stripping and cleaning it so nothing was rushed. I used the Autotech Guide you can find on their website: http://www.autotech.com/instructions/i127100k.pdf



The autotech guide is pretty good so if you stick to it you cant go wrong, they have listed the tools required in the guide but i will list what i used.

All tools and surfaces were cleaned thouroughly with IPA wipes to remove any soiling and small particles.

Tools:

18mm socket & ratchet

13mm spanner

14mm spanner

17mm spanner



Imperial spanners where used for the larger fittings as most of my larger tools are imperial not metric

15/16" spanner or 24mm

1" 1/4 spanner or 32mm



T25 Security Bit With Screwdriver attachment








Cleaning:

Polythene Sheet To Cover Surface

IPA Wipes

IPA Aerosol

IPA Fluid

Compressor & Air Nozzle



IPA PRODUCTS



AIR NOZZLE



CLEANING SETUP





HPFP BEFORE STRIP




I worked in accordance with the Autotech guide and everything went to plan, the process to strip and clean took about an hour.



The process i used to clean the parts was:

1.Submerge component in IPA for around 60seconds then scrub thoroughly with brush

2.If components has area that are hard to get to use IPA Spray Can to flush the area clean.

3.Use IPA Wipes to finally go over the component and remove any soiling.

4.Using the Air Nozzle, Blow the component to remove any excess IPA.



Once i had carried out the process above the parts were placed on IPA Wipes on a clean surface till i was ready to bag the components.



STRIPPED INTO BITS














PARTS CLEANED AND PLACED ON IPA WIPES READY FOR BAGGING







The Image below shows the internal components split into two bags, i decided to put the larger bulkier components together as i didnt want to cause any metal to metal damage from a heavier components striking a smaller more fragile one. The Spring, Piston etc in one bag and parts from the Relief Valve etc in another bag.

CLEANED AND BAGGED







Once all the internal components were bagged, i re-assembled the housing, screwing all fittings back in loose. Once put together loose the pump body and fittings was bagged.

 

 ALL THESE PARTS WERE INSTALLED TO THE BODY LOOSE.



CLEANED AND ASSEMBLED LOOSE THEN BAGGED TILL AUTOTECH KIT ARRIVES





Ill add pictures of the rebuild once i recieve the Autotech Internals



Cheers Davie

Cheers for the comments, you not for giving it a go yourself mate? I enjoyed stripping it down and cleaning it and cleaning it. Do you have a spare pump or are you going to use the one on your car?

Decided to get the pump built back together tonight, took a few pictures as i went. Didnt take as many as i would have like but i was quite paranoid about getting any foreign paticles on the components during build.

 

Anyway here's a quick and simple write up:

Set the bench up again and covered with clean polythene which was all wiped down the IPA wipes to ensure cleanliness. All tools and equipment was also cleaned in the same manner.





All the parts were removed from the bags and placed on the table, all parts were given a final clean with IPA wipes prior to assembly

The internals were removed from the box and placed on IPA wipes, these were wiped down with IPA wipes also, ignore the metal button at the top of the picture this is part of the OEM setup.



Pump partially assembled, ready for autotech internals


Autotech internals installed just the spring and retainer and collets to fit


Installation of Autotech Internals Complete



All boxed and ready to fit this week



If you follow the Autotech instructions and keep everything immaculate you wont have any issues. Sorry there isnt much detail but as the assembly is critical i was being extra careful so didnt get many photos taken.
