A bit of an update. One of my modified pumps did the RAC rally of the tests 750 miles 3 days 35 special tests https://youtu.be/GZ0-y0Y20_k?si=xxY3UXoFSI8OF_1Y we appear at 13.20 mins to 15.15 if you want to just see an imp in action. Stripped the pump after the event and all was good. I have done two more as spares for my car and will replace and inspect them as the car gets used. The one I fitted to a road going clan has still not be used on the road, so will be interesting when it first gets used after so long stood still. I have been asked to do one for another rally car, I have not had time to look at doing them in batches and for road cars as I am too busy. I have done the costs for this one except the cerakoting as mine were all sent with big batches of parts.
Strip old pump and blast clean, machine impeller for shims, clean all threads I have allowed 2 hours for this as you can get seized pulleys and bolts etc £100
Rebuild kit inc balanced seals that are better quality than the normal kit ones Timken sealed bearings £48
New nuts bolts and washers £8 this is for the rally version with no rear fan but should be about the same for the longer bolt kit for the rear cowl
I also have some top hat spacers I can fit to prevent the damage to red cowl when tightening up the bolts these are £7 for four
I have allowed 1 hour to bond shims on, check for being parallel in lathe with DTi and use ant-seize on bolts and bond gasket with threebond sealer ThreeBond TB1215 Grey OEM Engine Gasket
so £50 which inc costs of threebond, anti-seize and belzona bonding compound
When the parts come back from cerakote for this pump I will update those costs. It is a 30 minute drive to the coaters so I post small items this one to post out was £8
Total for this pump so far £222.79 plus the cerakoting costs the cost will be for impellor, pump bodies, alt tensioner bracket, metal mount and ally mount and timing marker. This pump was a pig to get apart even with the press tools I have made to prevent damage when splitting the pump. With the chances of receiving scrap back in exchange etc I will not be marketing these as off the shelf exchange pumps. What I can do is parts of the task if someone wanted to do their own pump, like send be a stripped pump and I will blast modify and coat then send back with a proper quality rebuild kit. Any way as i do not have a long term high road use pump to prove this works I will not be offering any sort of promise with this set up. There are variables that can case problems, like people using poor sealant, damaging seals when installing or assembling etc etc. So there is the update, if anyone wants help or parts doing for their own pump get in touch I will help. If someone wants pump fully done by me it will be a 3-4 week turn around, depending on mine and the cerakote company work load so it will not be a stock item, or Amazon delivery times.
