How do you time a Lucas injection pump?
How do you time a Lucas injection pump?
For gear driven coolant pumps: Remove the coolant pump, see operation 21-3. 4 Insert the timing pin (B1) through the hole (B5) in the fuel pump gear and the slot of the hub (B4). Push the pin fully into the hole (B3) in the body of the fuel pump. If the pin can be fully inserted then the pump timing is correct.
How do I adjust my Lucas CAV pump?
Turn the engine over until you can get to the one on the away side, then back to the one that is near the notch. Loosen both bolts a turn or 2. Then to adjust fuel move that little notch.
How do I turn my Lucas CAV fuel pump on?
Turn the engine over until you can get to the one on the away side, then back to the one that is near the notch. Loosen both bolts a turn or 2. Then to adjust fuel move that little notch. In the direction of rotation to lean, away from rotation to richen.
Where are the timing marks on a CAV injection pump?
Your CAV injection pump has a scribe line on the pump front mounting flange, which aligns with pump timing marks on the engine front plate. If you look at the pump mounting flange, it is easy to see, right in front of you.
Where is the timing mark on a DPA pump?
Slacken the pump boddy and turn it till the square end of the circlip lines up with the scribe mark on the rotor. The mark is lettered A on 4 cyl engines and D on 6 cyl. Lock up the pump in that position and make your own new timing mark on the pump flange, a sharp chisel does the job nicely.

Is there a cold start on a CAV DPA pump?
This was opperated by a small screw under the pump body which had a “T” bar through it. Screwing this out retarded the timing a few degrees. The position of this cold start screw would affect the internal timing marks and consequently the power. I have never seen this cold start feature used on any other engines. Re: Timing CAV. DPA Pumps
Where is the timing pin on a CAV pump?
However, if you want it to be EXACTLY correct, it needs to be on TDC & the letter in the pump window lined up. The idea of the timing pin was an advanced idea by the CDC engine designers to assist doing this type of job. The pin would lock the engine at TDC, the pump would be fitted with it’s timing marks aligned, also locked in place.
What are the timing marks on a pump?
No.1 Point of injection marks. If the pump has been fitted to the engine before all that is needed is to line up the marks on the pump flange and gear housing and lock up the three 1/2 AF – 13mm. nuts. One mm. of rotation of the pump body at these marks represents about one degree at the crankshaft. External timing marks.
Where are the timing marks on the Stanadyne DB4?
Two injection pump timing marks are used on the Stanadyne DB4 for timing injection of fuel into the Number 1 cylinder. One mark is located on the governor weight retainer hub. The other is located on the internal cam ring. These two marks must be aligned at Number 1 cylinder top dead center (TDC).
Can you reset the timing marks on a new engine?
On a new engine the pumps are individualy fitted before the timing marks are scribed so they are a matched pair. If you have to fit a strange pump, and the engine doesn’t perform, it is possible to reset these timing marks visualy.
