Makita 9227C spindle disassembly

merci · 05-24-05, 09:06

I wanted to replace the spindle of my Makita 9227C with one that has a thread size of 5/8"-11 UNC. Mine is M16x2.

I got the new spindle (labeled #50 in the schematic below) from toolpartsdirect.com but I got stuck trying to remove the old spindle from the assembly.

Check out the schematic here.

Attached are pics of what I'm trying to disassemble.

I can't get to the retaining ring (labeled #46 in the schematic) which I believe is the only thing standing in my way.

Any ideas?

Side view:

I can't see the retaining ring no matter how hard I look. Can this be disassembled at all?

Seems to me you will need to get a gear puller and pull the gear off the spindle shaft, Be careful not to bur the end of the shaft, it looks like it may slip in to a bearing or a bushing up in the head assembly. Then the snap ring will be exposed fur removal.

good luck.

Just curious, why did you want to change the spindle?

I imagine for the same reasons I'm condiering changing the spindle if I buy a UK 9227 (which comes with an M14 spindle), and that is that there are far more backing plate etc options for a 5/8" spindle than there are for either the M14 or M16 spindle.

This is the reason I'm considering importing a US 9227, instead of buying one here in the UK.

BenP answered your question for me.

BenP, you can actually modify it without removing the spindle - just buy the parts to make a new assembly:

#45 226744-6 SPIRAL BEVEL GEAR 52
#46 962151-6 RETAINING RING R-32
#47 211106-1 B. BEARING 6201LLB
#48 316896-2 HOUSING W/O BEARING
#50 152552-8 SPINDLE COMPLETE

Total cost (no shipping yet): USD70.03

I can actually use 5/8"-11 UNC backing plates but only the first two threads of the spindle are holding it together. It seems dangerous but I've never had a backing plate unscrew and fly on me yet even at maximum speed (3000rpm spin cycle to remove excess water from pads).

Merci, I am using a Makita 9227C with M16X2 thread size. My Meguiar's W-64 5" backing plate which is suitable for 5/8"-11UNC spindle thread could be turned for the first few rounds, as you mentioned. It works OK so far but I don't feel the sense of security of using it. So, I've ordered a M16 117mm (4.5") foam support backing plate from Flexipads for my Makita. You can find it from their website: Flexipads

Model number is 36357. They have backing plates for M14X2 as well. Cheers!

I recently bought a 'Flexipads' backing plate for my UK Makita and it didn't spin centrally, so I sent it back and got another one which was even worse! So I sent that back and got a refund. I was messing around for ages trying to centre the polishing pad to it... and then realised it was the backing plate that was causing it to spin off centre!

Your best bet is to get in touch with Meguiars UK and ask for their 14mm threaded backing plates... they do a 5" and a 6" backing plate. The product codes are SM-125 and SM-150. I have both... well I am an Autopian, what do ya expect! LOL

Pugoman, thanks for your feedback. Unfortunately mine is a unit with M16X2 thread. I could only try the Flexipad's M16 backing pad. Anyway, the dealer is my friend, and it only costs me GBP5. If I'm not satisfied, I will not buy from him. Will try it tomorrow. Thanks!

pugoman - the main reason I want a 5/8" spindle is that I'm eager to try the Edge 2000 pads as it will take all the hassle out of centering pads on a backing plate, but as of yet I haven't seen an adaptor for any spindle other than the 5/8".

Ben... a 14mm adaptor IS available for use with Edge pads.

Bargain! Now the other question - do I import a US machine for $195 and risk getting stung for import tax, or just buy a UK one and accept our stupidly high prices (£170)...
