Moderator Cynic Posted May 8, 2009 Moderator Share Posted May 8, 2009 Ok the original sw arm on my DT had to be cut out of the chassis cos the spindle had siezed solid within the bush and its still solid. I have a second arm but that for some reason is narrower by 1/8 of an inch (exactly thats why i used old money) where the spindle fits but its a gradual increace from the bracings and there are no signs whatsoever of damage. But that 1/8th of an inch makes getting the wheel assy in and out a complete ba5t4rd. My gut says its manufacturing issues with the spare arm rather than any real fult. Y'know a Friday special. So do i fanny about with my old arm, or 'adjust' the spare? I still cant believe the bush spacer/sleeve and spindle are so tight on my original when its only held in by plastic bushes.........

Moderator Airhead Posted May 8, 2009 Moderator Share Posted May 8, 2009 Cant you drift the seized pivot out? its only in plastic bushes anyhow so either pivot or bush should move. support the arm bosses on a strong vise with the jaws just open enough to clear the piovot.

I'll give that a go this afternoon but it does seem exceptionally tight. Link to comment Share on other sites More sharing options...

Aheavy hammer, a good strong drift and someone to hold the thing. The key is to support it on the heavy vise, I would be very surprised if you dont win the battle.

Hi Cynic, in the past I had loads of swing arm spindles on DT seize up, not un common I'm afraid. I would guess the arms are from to different years as I had that problem (wheel not fitting) too and is not a friday one, just to be used with different components. Regarding the spindle removal ; have you cut thro the spindle in order to remove the arm from the bike or is it still in one peice ? dependant on which way you have gone will make a difference on which way to go forward & to de honest I would forget the spare arm Regards Jim Link to comment Share on other sites More sharing options...

As it is apart from the end of the bushes and the bush covers on the end of the swing arm nothing was harmed in cutting the spindle but i now have an arm with the spindle and bush remains flush with the sides.

I didn't read the post correctly ! (part & parcel of getting old I guess) So to remove the bits of the spindle get hold of the following :- Freeing agent blow torch pad type hacksaw big hammer a supply of drifts Good quality stillsons a tubular support (to put over the swing arm where the spindle fits thro the bush) Then run the freeing agent between the remains of the spindle & bush (this make take frequent applications over a day or so) locate the tublular support over the Swing arm (were the remains of the spindle is) and on the floor at the other end. beat the poo out of the remains of the spindle from the other side. If you get movement and mangage to get enuff spindle showing to get the stillsons on it stop. Soak the bush/splindle area in freeing agent and leave for a while. secure the S/A in a vice and attach the stillson to the exposed spindle and work clockwise & counterclock wise, adding more lube/freeing agent at regular intervals. If you manage to get the spindle turning quite freely it should now just knock out. This is method #1 others to follow Regards Jim Link to comment Share on other sites More sharing options...

Moderator Cynic Posted May 8, 2009 Author Moderator Share Posted May 8, 2009 Yes success....... BFH penetrating oil and my head. It apears i was being a twat also, i was trying to get the SPINDLE out, tit. Its fukct anyway, once i cleared that milestone i got it in the vice, 2lb hammer and a long steel drift. Isn't violence refreshing in its proper place i felt great after i'd beaten the crap out of it, literally in this case. Many thanks people, i was lacking in focus there.

Moderator Airhead Posted May 8, 2009 Moderator Share Posted May 8, 2009 Youre gonna need one of These now Jason! Edit: Just noticed they are listed as DT175 so you will have to contact them to measure it up, failing that compare part numbers between yours and a twin shock model.

Hi Cynic, its quite supprising what you can do with a two lb hammer & a drift, I guess you also managed to get the bushes/plastic top hats out ok ?

Moderator Cynic Posted May 9, 2009 Author Moderator Share Posted May 9, 2009 Hi Cynic, add to yearly service list :- remove s/a spindle & copper slip it Regards Jim Much as it pains me to admit it the old nail has not had the love and hugs that the 600 gets. Over the winter the 600 gets its steering head bearings and the complete rear sus linkage stripped and greaced oil changed etc, as well as a thourough under the skin clean. The nail takes up the transport duties when the salt comes out and the roads get nasty. Then in the summer it gets a bit of tlc but nowhere near what she deserves and i think this is payback. Although it proves just how strong these little bikes are. Now she is stripped right out i can fix my own bodges and give her back a bit of pizazz, and not use her in the shit and salt. Maybe run round the show circuit, a lot of the steam rally's let you camp for free when you exhibit and there is cheap beer etc. Link to comment Share on other sites More sharing options...

wild foamy Posted May 9, 2009 Share Posted May 9, 2009 if you can get into dorset steam rally at the end of the year (september) its a good crack down there, wobble out of the beer tent at midnight and get on the reverse bungee ball Link to comment Share on other sites More sharing options...
