DAN82SED Posted July 8, 2013 Share Posted July 8, 2013 trying to get my head round fitting a used injector pump as a replacement for my knackered one. I know the tdc mark on the fly wheel will make 1 revolution compared to 2 for the cam and pump. Could anyone tell me if its possible to fit a second hand injector pump 360 degrees off the tdc? and if so how do i know if its right? hope i made sense, this will be my first attempt messing with timing cheers Dan Quote Link to comment Share on other sites More sharing options...
western Posted July 8, 2013 Share Posted July 8, 2013 IIRC the injection pump timing pin will only fit at the correct point & the small lock screw on pumps right hand side should be engaged & have it's keeper plate removed when set correctly.

Puffernutter Posted July 8, 2013 Share Posted July 8, 2013 Also, mark everything else before you take the old belt off! You can adjust the pump slightly on its plate, but only about 1/2 tooth. Cheers Peter Quote Link to comment Share on other sites More sharing options...
DAN82SED Posted July 20, 2013 Author Share Posted July 20, 2013 sorry for late reply, had issues with broad band. To update, swapped the pump out but it refused to fire. rotated it 360 degrees and still woulnt fire. i refitted the old pump and it started straight away. ive been advised to use easy start to try get the none working pump going. Any thoughts? ive heard its bad for deisel engines Also, reason i wanted to change the injection pump was because the previous owner said that a garage had discovered swarf/ metal filings in the soloinoid. How bad/ what consiquences would this have on the engine if i kept driving it? cheers Dan Quote Link to comment Share on other sites More sharing options...

How bad/ what consiquences would this have on the engine if i kept driving it? it won't have any affect on the engine, because the swarf cannot get past the shut off solenoid, it comes from the cam plate & roller which pressurise the fuel inside the FIP, it will stop the FIP from operating or even starting as mine did,a rebuild with new parts will be required, mine was done about 6 years ago.

western Posted July 20, 2013 Share Posted July 20, 2013 I cleaned mine out about 10 times, then one day it just wouldn't start even after cleaning & leaving the plunger out. Quote Link to comment Share on other sites More sharing options...
Snagger Posted July 20, 2013 Share Posted July 20, 2013 I've had pumps and injectors rebuilt by "DieselBob" and have been pleased with the results. I can recommend him to rebuild yours. He does have heavy duty alternative parts for some of the higher wear prone Bosch parts, and I don;t recall them costing much extra. I think I paid about £50 for a full pump rebuild, and I think that may have included injector overhaul too, but it's hard to remember as it was back in 2008!
