JR3000VT - Recip. Saw

[Al in IL]

While recently using my friends Makita JR3000VT to disassemble my wood pool deck, the clamp assembly that holds the blade had come apart in pieces.

I was able to find the following parts on the ground. (referenced parts using the numbered diagram on this site) #1-clamp, #2-steel ball, #3-pin, #4-torx bolt, #7-push button, #8-compression spring. When I reassembled these, the spring and push button slid down the shaft. What am I missing?

According to my friend, he's had problems with the #4-torx bolt in the past.

I'd like to reassemble with all the parts necessary to get it up and working including replacing everything from #1 thru #8.(except maybe #1 & #7)

I took this saw to an authorized Makita service center, waited a week and they told me that it would cost over $80.00 in parts & labor to reassemble, and I should just consider purchasing a new one they have on sale.

My question: Do/Are #9-Ring and #10-Seal inside the housing or outside? Could these be the missing components causing blade clamp assembly to slide down the slider shaft?

It's really a good working saw and I'd like to salvage, but not for $80 bucks!

Thanks in advance.

Yeah, you will probably be able to fix the saw for less than $80!

As far as I know, #9 and #10 are inside the housing so replacing them will probably not fix the problem. Actually, they're not involved with holding the blade clamp in place. The #4 screw is really the piece that holds everything together and if it's not tightly in place then the clamp will malfunction. I would even recommend using some Loctite on that screw to prevent it from backing out.

I think you're right about purchasing #1 through #8. You may not need the #7 push button but it's possible that your #1 blade clamp is broken or malformed. I would probably replace that. Without the #7 push button, the parts come to $22.59 which is pretty livable. These are all very commonly replaced parts and the repair shouldn't take you too long.

Here's a link to the JR3000VT page just for reference:

Thanks for the help Mike!

Just placed my order. I'll update when I receive and assemble.

BTW - This is an awesome site and forum.
