andym Posted November 28, 2019 Share Posted November 28, 2019 There was a firm who used to overhaul them but I can't remember the name. I suspect that's who Marcus sends them to. I've had a couple from Marcus with no issues at all. Andy Quote Link to comment Share on other sites More sharing options...
fv1609 Posted November 28, 2019 Share Posted November 28, 2019 Andy were you thinking of Marcus Engineering (Wirral) Company Limited they refurbished carbs etc vehicles in NI. Some years ago I ordered a lot of carb spares from them, but they seemed to have ceased trading under that name in 2003. Quote Link to comment Share on other sites More sharing options...

Stuartarmytank Posted December 2, 2019 Author Share Posted December 2, 2019 the seals and rear bearing were available locally they are standard sizes. The front bearing is the impeller shaft housing , it needed a light hone as previous work had damaged it. assemble the armature into the forward pump housing. assemble the rear motor housing onto the field case (brushes out) then place that over the armature and secure with two screws.

Stuartarmytank Posted December 2, 2019 Author Share Posted December 2, 2019 There is a felt washer between the two front seals . I soaked them in moly grease . The rear bearing is a bronze bush . I sprayed it with moly cote and put moly grease in the void between the end of the armature and the top of the case plugged the hole with a felt seal to hold the grease in.

Stuartarmytank Posted December 6, 2019 Author Share Posted December 6, 2019 Pump finally done. Some pictures that might be helpful for someone contemplating doing one. The test set up allowed me to check flow and pressure using a restrictor and pressure gauge on the output spout . Started at 12V to see that rotation and wiring were ok then 24V 432 Lp Fuel pump diesel.pdf 1 Quote Link to comment Share on other sites More sharing options...

09EA50 Posted September 23, 2022 Share Posted September 23, 2022 Hi, You say "seals and rear bearing were available locally they are standard sizes" it would be very helpful if you could tell us the supplier and if possible;e any part numbers. Also did you get new brushes? I have mine in bits the seals don't look bad very small amount of leakage, It would be nice the get replacements before I extract them. I have New Pump liner & Impeller blades. Graham Quote Link to comment Share on other sites More sharing options...

09EA50 Posted September 23, 2022 Share Posted September 23, 2022 Just realised front Oil seal may be different part, not got it out yet, was hopeing not to pull them untill replacements arrive but front seal may be different (422 & 423 of 2350-T-251-711) so, Stuart if you do know the part No it would be appreciated.

andym Posted September 24, 2022 Share Posted September 24, 2022 Brake cleaner usually works well on the filter, but gently scrape off any excess gunge first. Andy Quote Link to comment Share on other sites More sharing options...
