70HONEYMONSTER Posted November 29, 2011 Share Posted November 29, 2011 I want to remove the injection pump from the Gardner 6lw engine .Is it a fairly straight forward task to remove the pump to be cleaned without upsetting the timing.This would enable the engine to be cleaned and painted then the cleaned pump to be reinstalled without to much hassle.When the pump is removed, can the timing shaft be left in the same place so that it does not require to be timed upon instalation?

Plantters Posted November 30, 2011 Share Posted November 30, 2011 Hi, Removal of the whole injection pump is not the most difficult of jobs but will generally mean retiming as you will have to de-mesh the drive gear. As far as I am aware there is not an easy way of removing the pump and leaving the gear in situ. Regards Nigel Quote Link to comment Share on other sites More sharing options...
70HONEYMONSTER Posted November 30, 2011 Author Share Posted November 30, 2011 Hi Nigel, Think we,re getting our wires crossed.All I want to do is unbolt the pump,take it off ,clean it up and bolt it back on to the newly painted engine.The drive gear would stay with the pump.If the drive gear was not rotated in the pump housing and is in the same position as when re-moved is it just a case of bolting back on to the engine or would it have to be re timed ?

Scammell4199 Posted November 30, 2011 Share Posted November 30, 2011 if you removed the oil filler neck would that give you sufficient access to put a small centre punch or premanent marker on two adjoining teeth, one on the timing gear and one on the pump gear, thereby recording their orientation with one another.

Plantters Posted December 1, 2011 Share Posted December 1, 2011 (edited) Is this any help mate ? Nice scan Andy but unfortunately this only describes removal of the pump units themselves and not the lower cam housing. As Richard siad, if you remove the oil filler neck then the gear that drives the injection pump from the main cam is on display and pop marks can be placed on the gears to aid correct re-assembly or you can use the ones that should already be there by turning the engine until they line up. Trying to do it without removing the filler neck will be very hit and miss due to the fact that the gear on the pump will turn slightly as it is withdrawn due to pressure on one of the cam lobes against the tappets of the pump itself. You will also have to remove the Advance / Retard mechanism that is located on the side of the timing case as this sits behind the driven gear and moves the gear along the shaft to alter the fuel delivery timing at given engine speeds. Good luck Nigel Edited December 1, 2011 by Plantters Quote Link to comment Share on other sites More sharing options...
70HONEYMONSTER Posted December 1, 2011 Author Share Posted December 1, 2011 Thanks Guys, You beat me to it Nigel about Andy,s scan. Andy,I do have a copy of the manual, but as Nigel states, the information is more about the removal of the pumps rather than the cam box,but thanks anyway. Nigel, I am going to remove the radiator anyway so will be able to remove the oil filler plate along with the front timming plate cover to allow marking the gears.Will the pump and cam box pull straight out without removing the advance and retard mechanism? ObviouslyI will have to remove the connecting rod from the throttle linkcage. Quote Link to comment Share on other sites More sharing options...
AndyFowler Posted December 1, 2011 Share Posted December 1, 2011 Ok mate sorry it was no help , have you seen the Gardner manuals on Ebay at the moment ? Maybe if you have time you could show some photos of the removal and refit as I for one would find them interesting ! Also a video of the old beast firing up if you have a chance ! (yes I know I'm sad) :D Quote Link to comment Share on other sites More sharing options...
70HONEYMONSTER Posted December 1, 2011 Author Share Posted December 1, 2011 Andy, Will post photos when I get it removed.Have some video of the "Beast" running but will need to get it uplaoded.Will also have to start a thread of the rest of the restoration .Busy just now stripping the chassis of all bits which can be taken off ,stripped ,cleaned and primed.How,s Daisy coming along or is she all tucked up for winter?

Not difficult to do though, just undo the bolts and the whole assy slides out. Quote Link to comment Share on other sites More sharing options...
jerry Posted July 10, 2012 Share Posted July 10, 2012 Hello, I see they are old posts, have you removed it now. If not, I can help.... Quote Link to comment Share on other sites More sharing options...
70HONEYMONSTER Posted July 15, 2012 Author Share Posted July 15, 2012 Hi Jerry, I have not removed the injection pump yet.Have been doing the cylinder head gasket first and was going to test run the engine first before removing the pump.Any information about removal of the pump would be most appreciated. Cheers Bryan Quote Link to comment Share on other sites More sharing options...
jerry Posted July 15, 2012 Share Posted July 15, 2012 Ok, its very easy, whether my description of how to do it will make it sound so remains to be seen. Turn the engine over by the ring gear in an anti-clockwise drection through the inspection hatch (top of the flywheel housing) until the marks for number one cylinder come into vision (on the flywheel). Then depending on whether the advance is set forwards or backwards, read off the settings on the housing and look for these on the flywheel and align them with the pointer in the inspection hatch. Now look at the injection pump and number one injection pump element, there is a little window in the body, and this has a scribed line on it, this will align (if the timming is set correctly in the first place) with a scribed line on the mooving element inside the pump. Then its simply a case of removing the pump. The first time it takes a bit of time but from then on, it can be done in minuites. The engine can be turned over with the pump removed without any issues.... Jerry Quote Link to comment Share on other sites More sharing options...
70HONEYMONSTER Posted July 15, 2012 Author Share Posted July 15, 2012 Cheers for that Jerry.I will keep this information handy when I get around to removing the pump.Will probably be back in touch when the time arrives. Bryan Quote Link to comment Share on other sites More sharing options...
