So now I have an issue with a spring. The spring popped out and landed in the little devit under the crank handle. I am no mechanic – but I’m pretty sure that I need that spring to be attached to something. I’ve looked at the plans and I think the part is number 106. Question is how to fix this – I know I could take it to the repair shop (if the near one is still open that is), but if someone can explain how to fix it I’d appreciate it. I have a picture of the spring.

I can’t get the diagram to blow up enough to actually see the spring – but I believe that my spring is missing it’s one end as it only has one hook.

Any help would be appreciated it.

It is difficult to tell from the DeWalt diagram but I’d bet that the spring originally had a loop on both ends. As a temporary fix (till the new part arrives) you could take a pair of needle-nose pliers and bend the “broken” end of the spring into a loop. Bend out about one “ring” of the spring wire to form a loop similar to the “good” end. You might even find the other loop end attached to its’ proper place inside the planer.

From what I can see, the spring keeps tension on part 107, which appears to take up any slack in the chain drive. You could probably pick up a very similar spring at the Borg in their hardware department. The local Lowes has a section of “Blue Drawers” with quite a large variety of speciality hardware.

Hope this helps.

It’s been a while since I was that deep in my planer, but it looks like a chain tensioner spring. Pull off the side cover and see if it’s missing. If so it’s an easy fix.
Tool parts direct has one in stock and it will run you all of 98 cents.

Please let the rest of us DW735 owners know how this all plays out. In looking at the parts list from Willie’s link above there are two of those springs. I pulled the cover on my planer, but that was not enough to see all that is going on. I believe I could see where the spring on the right (as facing the planer) hooks into the frame, but that is about it.

The idea of bending the end of the spring to form a new hook is a good one, but it kind of depends on how long the original was. If the spring broke in the middle, then fashioning a new end might result in way too much tension. Then again, I would want to know what became of the rest of the spring. Having a chunk of metal floating around in the planer doesn’t sound good.

Let us know. Actually, you could become famous on YouTube by posting a detailed video of your spring replacement project.

Okay – so I’ve pulled the side cover off and what do you know – the other end of the spring is still stuck in the machine frame and it does appear to be part of the tensioner. This makes perfect sense because—- as soon as I noticed the spring laying in the tray is when I noticed that my crank handle was so loose that I could move it around a whole rotation without moving the blades down. I tried to get a picture but it’s such a thin wire you can’t really see it. The part of the spring I still have is not long enough to make a new loop and reattach. I’m going to stop by the box store and see if I can find a similar spring – if that doesn’t work I’ll go ahead and get the replacement part on the net.

I’m glad you all answered this – I would probably never have looked up into the frame. I think once I get the spring I can actually fix this thing myself!!

Another good thing about this is that I get to clean out the dust and crud that is in the chain and related parts.

Thanks for all your help. I’ll try to get some good pictures of the repair.

I appreciate all the help!

EVERY shop should have a box of these on the shelf…

You don’t have to buy them from HF, but I’ll tell you, they are all the same….no need going to high end suppliers for the cheap stuff….

You can tile two pieces together with a copper wire for the time being. Wind the wire around the two last coils on each piece. You can saturate it with a superglue after that so the spring won’t slip out of the wire. ( A temporary fix usually is the most permanent one).

Well it took a while to get back to this. Vacation at Disney World got in the way – if I never see another roller coaster the rest of my life it will be too soon!!!!!

I looked for a comparable spring at HD, Lowe’s and Ace with no luck so I ended up ordering on line.

First off – you should know that such a small spring still bounces quite well when dropped on a concrete floor. When your hands shake as much as mine do – it was, unfortunately, a common event. I apologize for the size of the following photos – I’ve still not figured out how to crop them and make it stick – but that’s okay – I’ve decided not to let it bother me too much.

I have pretty small hands but it was still a challenge to hold onto the spring and try to get it in the appropriate slots.

To see the slot better and to have an edge to try to steady my hand I unbolted the planer from it’s table and slid it to the very edge of the table. This had three advantages – as I already said it provided a rest for my arm. The second thing it did for me was give me a better angle to see the slot as now I can see the light shining through the slots.

The two slots are to the right side of the photo below.

It’s a bit hard to see but the left slot is elongated to just a hair over the width of the spring’s hook.

The third thing moving the planer to the edge is it allowed me to see down into the machine while trying to place the hook.

What I did was to place the hook up against the left slot with my left hand and while watching the slot from above, once I got the hook to the slot and pushed through, I used my right index finger to guide the hook into the right slot. It’s a bit hard to describe, but you have to push the hook up and once in the slot, angle it a bit to the left to get the open end of the hook up and into the planer – once I accomplished that I was able to guide the open end into the right slot. It took me about 15 tries to accomplish this – but if your hands don’t shake it should be a quick and easy task.

After the spring is hooked through the top – all you have to do is stretch out the sling and attach it to the lever.

Before closing up the panel I also took a little time to clean up some of the gunk and dust inside.

Now I’m ready to get back to work!

Thanks for all the advice.
