Default C4 Hydraulic pump failure

Hi, my first post and I need as much advice on this one as I can get!

I have searched endlessly for suppliers of parts for the electric motor for the hydraulic unit, I'm beginning to think that it's all pretty well sown up & that it's new or s/hand as the only options.

Has anybody managed to repair the Ate motor or find a specialist who can, I'm really not keen to buy new.

And as a note when the pump jams and the fuse blows the only warning you get is lots of adrenalin and a very sore calf muscle.

Cheers
Kevin

Default Pump Offers

Thanks to all for the offers of various pumps, having had time to make some enquiries regarding reconditioning etc, I have gone down the buy it new route, thought long and hard and bit the bullet.

I have however found out a few interesting things, the motor for the pump can be reconditioned for about £250 as long as the brush gear is sound, my armarture needs rewinding, brushes replacing, new seal and bearings.

The Porsche pump is virtually identical to the model fitted on a Jaguar XJS, loads for sale s/hand in the USA on ebay, I fancy the use of the main pump body with minor mods to the connector and change out the high/low switch it would work.

The failure on my pump looks like it was caused by a failure on the high pressure switch, causing the pump to run unchecked until it stalled, burnt out and blew the 40 amp fuse, I have yet to check the high/low pressure switch, the new pump comes with the switch, I also replaced the relay, one of the contacts looked discoloured and it's age is unknown.
