I've never timed a WD45D, but I have timed a D17D and I found it to be very easy. I'm not sure about the 45D, but on the D17D you have to be careful that you don't roll the shaft seal on the pump drive shaft. Rolling that shaft seal over causes a fuel leak into the crankcase. When I put new fuel filters in my 17, I used my shop vac to prime the system. I put the hose on the blowing outlet of the vac and used it to pressurize the tank. With the fuel supply line loose on the pump, it filled the system quickly, and the engine started quickly and easily. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

First you need the FPI mark in the center of the timing hole, with cylinder number one on compression stroke. Then you can install the pump the camshaft should have a marked tooth there if everything is positioned correct.  If the pump gear is mounted on the pump properly there should be a marked tooth there as well. The slotted holes on the pump gear allow you to do a bit of fine tuning. There is a marked tooth on the pump plunger drive seen through the side cover. It should be one tooth off from the mark.  There is a purpose for the marked tooth to line up with the mark when disassembling the pump but not for timing the pump to the tractor. HTH Tom |

I decided to take a picture of my spare pump that would show the proper place to line the pump up when the engine is positioned as described above. This mark can be seen - not easily - through the tiny hole on top of the timing gear cover when the plug is removed. Getting a picture of the mark when mounted on the tractor might require a laparoscope, anyway I didn't even try with a regular camera. When this is lined up with the pump on the table you can see that the tooth pictured above is one tooth off as shown. |

Looks like A-C really simplified pump timing on the 262 as compared to the 230. All I had to do was roll the engine around to #1 compression stroke and insert a pin into the flywheel. Match up the timing marks on the cam gear and pump gear, and rotate the pump so the marks in the window line up. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

| the pump timing on the 45-d is very easy if you get you some bright flourscent paint and mark the tip of the pointer and the mark on the gear.sure makes it stand out.the worst part of replacing the pump is the lube line on the bottom of the pump.i will not even attempt to use the origional steel lube line.get you 2 # 4 an aircraft fittings with pipe thread on one end where it screws into the engine oil vein and on the injection pump.get an an line and it sure is much simpler and faster |
