Topic tags/keywords: question sawzall refurbishing

Ok, spent $10 on a sawzall by Makita at a yard sale awhile back

Motor works great! The only thing wrong is the parts that hold the blade in place. Fellow said that a screw was missing

I removed the adjustable shoe, and the rubber boot. No blade clamp in site. Ordered the clamp from Makita.

Test fit showed a pin sticks out too far to allow a blade into the clamp. Clamp itself doesn’t quite go onto the arm. Close but not quite. There is a hole for a bolt in the rounded parts of both the clamp, and the arm. About the same place as that pin…

Sooo,,, Do I drill out that pin, re-tap the hole, and add a new bolt from the rounded side? Maybe use it to pull the clamp tight to the arm? I also picked up the set screw to hold the blade in the clamp. Just need to install the clamp.

Went out and bought a ToolShop $40 sawzall to tide me over until I can figure this Makita out. Used that one twice, so far. Would like to get the Makita up and running, bEFORE the toolshop one dies…

Any ideas out there….Buying a BRAND NEW SAW IS OUT. Have spent enough now on this project.

Bandit, I have that same saw. Won’t be able to get back to the shop until Monday. I’ll go check it out, maybe even take pictures to be sure. Let you know what I find

Bandit, these are photos of the saw we have at the firehouse. Appears the same. Looks like a screw with a head holds the clamp on the shaft and the other side has the set screw for taking blade on and off. Maybe the screw on the other side has the pin on it to line up with the no,e in the saw blade.

Well, maybe Gary can get better pictures than I did. I was in bed at the firehouse and saw the saw and realized we had one. Out to the maint. room in my…um…sleeping attire. It’s kind of dirty, but I wasn’t going to clean it at this time of night.

I’ve got one that’s about 20 years old… model JR3000V, so not sure if it’s the same… but mine looks like there is just a set screw on the flat, and a spring pin (or some type of pin) holding it in place on the opposite (round) side. The parts diagram online shows a screw instead, so maybe it was a design change. Here is what it looks like:


(set screw for securing blade)


(pin holding clamp in place)

Cheers,
Brad

PS: I’m guessing they replaced the pin with a screw on newer models. If your clamp has a hole where the screw/pin should be, them maybe you can put it on (without a blade) and press it back through the clamp so it’s not sticking into where the blade fits. Just a guess…

Model No. JR3000V is the one I have

May have to take the slider part out to fix this thing up…

Looks like they changed the clamp since mine was made…in 1993. Sooooo, I think I will tear it down a bit further, and get the end of the slider out where I can work it over a bit better….

Mine has a raised, flat boss on the rounded side, with a non-threaded hole in it. The “flat” side has a set screw. Don’t have that small of a metric tap, but I do have an SAE tap that is close. Used it on some bolts for a Stanley #39. Now, locktight on the threads for the round side bolt?

Ok, I tore the gear box apart today…lots of burnt gease ( YUCK) and burnt dust

Took the slider bar out, some of the bolts were a bit sticky. Got all the parts I needed for this rebuild

Way too much grease. Anyway, got the slider into the vise, and tried to get the old bolt out…..couldn’t get a grip. Ok, plan “B”. Visegrips to hold the bar steady in the correct directions. Drilled the old bolt out, with LOTS of oil on the bit. Finally got through! Grabbed a tap wrench and a 6×32 tap, and the oil can. Spun the tap to make new threads. Dug up a 6×32x 1/2” bolt, and tried the fit. Then added the new clamp. Bolt was actually the right length! Took the new bar back upstairs to the saw

Put all the parts back into the gearbox, plugged the saw in, and pulled the trigger once…....it WORKS! And no extra parts, either. Put the rubber boot back on, then the shoe. Had to scrounge up a 4mm allen wrench to add the shoe. It also works to clamp a blade in place

As the OEM one is missing, this will go onto the holder on the end of the cord. Hey, even a blade fits! The black set screw will even hold a blade in place! I think I can call this saw …...fixed.
