What a great idea! A magnetic wand can also help. Here's a solution I recently utilized for the reverse process; re-installing a bolt that holds a part in place, an Idle Air Control Valve in my case: I placed the part on a piece of paper with the "face" (which mates with the surface it returns to) against the paper. Next, I squeezed a small amount of GE Silicone into the bolt holes. Finally, I dropped the bolts into place and let it sit awhile. The thread-ends won't protrude beyond the part's face since they're all on the paper. The silicone holds the bolts in position, yet still allows them to be pushed & rotated upon re-installation. No more dropped or lost bolts.
I doubt I'll ever work on this engine, but this is just the sort of general tip that can lay in my mental processor - waiting for an application to come along. Whenever I have tricky situations like this, I try to balance what I expect/hope to happen against what can/may happen.
I stick one of those super strong ceramic magnets to any wrench, socket extension, etc., to help retain bolts and washers when they are being removed from difficult to access areas. The toilet paper roll is a great idea to provide even more avoidance of that sinking feeling when a bolt tumbles down into the abyss!
The magnet trick was great before manufacturers--especially motorcycle manufacturers-- started using stainless steel fasteners. I'm not complaining, mind--I love SS: but removal safety is a bit compromised.
First sentence is poorly written. Reads better like this: The injection pump must be separated during replacement from the timing gear that spins it. Does the timing gear spin it while you're replacing it?
The old adage remains true: If you want to find the center of a car, just drop a tool or a nut and it can always be found in the dead center of the greasy mess on the floor under the center of the car. If it does roll it will always disappear under any immovable object and is forever lost. Now, let's talk about "Jesus clips" and how they got their name. This is a true story. I've proven it many times.
Like many out there I am not at all familiar with these diesel engines My question is this: After the bolts have been removed I'm assuming the injector pump is to be replaced. Just what else is going to come out of that hole once the pump is unfastened from the timing gear?
I've used magnets to do some of this tricky bolt and other remove or replace business, also masking tape and other, far better to be safe than very sorry. As to bolts, nuts or tiny parts on the floor .... you'll never see them again, they go into what I call "never-never land", a place maybe invented by Rod Serling, I have no idea but in any event, it's gone so just forget it, I keep my floor clean and clear but does not help anything, it's gone.

Now that's a great idea! Love it. I can't say I've run into that sort of problem previously, but if I do now I have a spot in my brain that will remember this idea, so when I drop the first bolt, my memory can kick in and I can not do it a second time. 🙂
