Chain adjuster broken off (what to do best?)

SwingArm Buddy!
This was in the "Bionic leg" thread, 2nd page, about 1/2 way down. They sell them at rocky mnt atv, Probably other places also.
[quote="DoctorXRR"]The chain adjusting bolts snapped off in the swingarm, due to corrosion on the threads.
All I can say is thank goodness for the SwingArm Buddy!
The most difficult (and most important) part of the procedure is drilling out the broken bolts. You have to work your way up to with two smaller diameter drill bits before using the 3/8" bit provided in the kit. At least one of the smaller bits needs to be extra-long, otherwise your it will not clear the swingarm and you will drill crooked. Also critical, is making a very deep center punch mark - in the center of the broken bolt. I hit the center punch several times to be sure to get a deep punch mark. The finished 3/8" hole must be centered in the swingarm... not a procedure for the squeamish!

The kit makes a very solid repair and I applied anti-seize to the new adjusting bolts. The only down-side to the kit, is the new bolts are 5/16" american, which means you have to use a 1/2 wrench to adjust your chain, which may mean having to pack an extra wrench in your tool kit, although you might still get away with using a 13mm metric.

The steel insert is slightly over-sized compared to the 3/8" drill bit, so it is a good press fit into the swingarm.

Same old problem all imperial when are the US going to move with the rest of the world and go metric lol.

Frosty,

yer going to buy a new swinger because of a bolt stuck in your one???
Ya you should, and I'll pay the postage to send that old useless swinger over to me!

Serious, you haven't have you? Just drill it out or have it drilled out, but 'out' it will.

If he rides to my house I will let him sit there and drink my tea/coffee while I fix it for free.

I have spoke to Paul from manchester , http://www.xr650r.co.uk/ , i am going to attempt the repair , if i damage the swinger beyond repair he will sort replacement for me for a good price .
The way its broken , i have about half an inch of it sticking out , going to weld nut on it and try to get it out again , i hope that the heat from the welding proces will release the bugger .

Seriously, I hope you don't - but, as seriously, I will take it gladly!!!
I'll have it machined out, welded-up and re-drilled, would be darn nice to have a spare unit here.

I have a spare swingarm i will never use anymore, needs some welding so if anyone is intrested?............lets talk about money

'spare' = upused in your case Ricko.
Kom nou man, op is op!

hahaha ja die is op en upused ja

Wanted to get it fixed but then i got a 2nd hand swingarm from ebay.uk

GOOD GAWD!!!! I thought I was rough on bikes!!

thats what you can get if you forget loctite on youre sprocket bolts

Least your man enough to tell the truth Rikco...many people would say it was like this when they brought it....good call m8... worth checking them bolts once in a while

yes i still check em now before i go take a ride

i had more tears about the rear wheel that was only 140 kilometer old

4 weeks later i was back up and running, new rear wheel from the usa and the 2nd hand swinger from the uk

Where's the best place to buy those Excel rims from?

I love the look of them

look for a 2nd hand set on forums or ebay, new price is way to high

mine are from a crf

Are they 18" rims same as stock ?, they do look pretty must say

17inch (3,50'' front 5,00'' rear)

I have filled the repaired swing arm with polyurethane  foam  to prevent any moisture entering + to stop the rattle from the broke screw  , and most importantly loads and loads of grease on the brand new adjuster bolts

have to say here that easy-outs do work really well BUT you have to have good quality ones (http://store.snapon.com/Multi-Spline-Extractors-Extractor-Multi-Spline-1-8--P635483.aspx) and it takes a bit of good judgement to drill deep enough that the extractor can bite and screw in a bit to really grip but not to deep that you drill all the way through....

I have had a pair of these 1/8 snapon (fits the common size screw for aircraft inspection panels) ones for about 10 years, use them fairly regularly and haven't broken one yet!!!

That;s why you paid so much for them Mark, Snapon (a brand) won't Snapoff like all the others do

Actualy they would snap too , dont get me wrong i love snapon tools , they are the doggies nuts but did not work on my COMPLETELY seized barsterd , as the heating it up and freezing failed too , the last option was drilling it out and retap the hole  

well - despite having been on this forum for a while and reading this thread (and even commenting on it) I managed to shear off one of my adjusters....

so I can now positively attest to the fact that snap-on, and ONLY snap-on extractors work. That combined with spraying the adjuster with WD40 morning and night for 4 days till I got around to working on it.  I did break one extractor but that was only because I drilled the hole deep enough for the extractor to grab but still too shallow that it bottomed out in the hole and snapped.  I then attempted to drill right through so I could spray WD40 into the swingarm but my drill bit caught and snapped off in there - Doh!
Anyway tonight I successfully got it moving (with scary force on the extractor) with my second extractor and taking it real slow got the whole thing out.  It was pretty amazing to see that the WD40 had penetrated all the way up the threads.

All fixed ready for a long weekend ride up to a game park in the very north of the country
