It's all talk from her...........when I mended her washing machine all I got was a weak cup of coffee.....:Kiss:
So a bit more progress made. Finally got the rear shock off. The top bolt came out ok, but the bottom bolt had rusted in to the bearing. So after much Dblock spraying I got the bolt out which judging by the state of the nut, it was the rust holding the whole thing together. Any way could the assembled gurus see if they can identify the shock from these pictures
Nope...................'Cos it ain't the normal Showa or the Sachs Boge..........No reservoir. I don't think its an Ohlins, even.... It does slightly resemble the early Monster shocks, but the adjustment knob doesn't look right. I'll take a guess at Hagon, although it may be a Marzocchi, but from God knows what.
It looks like the Quadrant shock like is on mine, but my spring is blue. Clutch slave seals are the same as the wet clutch, I've got a spare new set here, got them from pro twin I think. Clutch kits are avalible, same as the 750 sport, and some of the paso' I think. I had to pump out my slave with grease but the seals were ok and are still ok at the min. Photo attached to keep you going.
Thanks @Lumbux judging by your picture my shock was installed upside down, the bottom bolt has been "modified" so the nyloc nut was held on by one thread and rust I'm thinking replacing the shock with either hyperpro or a Wilber's. Is there a preference ?
Does anyone know what the original fitment would have been, and does it really matter which way round the shock is mounted?
The very early 750 was fitted with a Marzocchi rear shock, which was then changed for a Showa and then a better Marzocchi.....all this happened in 1990...........thereafter some 900s were fitted with an Ohlins or Showa (although the steel swingarm 900 should have a Sachs Boge shock as do the 750 with the steel swingarm)..........the early 90s 750s appeared to end up with the Showa reservoir shock when the swingarm is ally. That's the best I can offer.......the Showa and Sachs Boge are mounted with the reservoir at the top.......won't fit otherwise. PS......I suggest you compare your ally swingarm with Lumbux's one...............his 750 one is definitely not the same as mine which is off an early 900ss.
The swing arm on my 400 is the same as my 750, as is the one on Mr. Mcr's 750. Must have been what was laying around the factory at the time!!
I'll check the width between the shock mount lugs of my ally swingarm so you know if a Showa will fit in there. Update....Haven't done it yet (at 22.03)....well, you aren't exactly in a hurry are you?
Slow and steady is the way forward, that and a lack of funds AL. I will measure up the gap I've got and post it up later. One thought crossed my mind, possibly a bit late, but should I get the engine soda blasted as one lump, and then how far do you guys think I should go in pulling the engine apart?
I would leave it one piece (with the inlet manifolds on) and plug up all the major holes and exposed threads etc.........It would save an awful lot of thread and hole protection which it would need if dismantled. Once it was clean and sparkly, I would start a gradual strip of the obvious things............I mean, does it turn over by hand at the moment? Are there any nasty scraping noises if it will turn over? Can you engage all the gears? Is there oil still in it? If they are all good, I would risk changing the filter, flushing out as much crap as possible and do a refill; then take a chance of firing it up.
That was pretty well much what my thinking was. Yes it does turn over by hand, 1st and 2nd would appear to be available, and there is some black substance in the sight glass that could be oil. If I can find a suitable socket/drift tonight I will see if the swing arm pivot wants to part company with the back of the engine
With all that corrosion let's hope the back of the engine doesn't part company from the front............
Looks like you might want to source a Showa with the reservoir..............You can borrow my Sachs Boge to do a trial fit, but it shouldn't be a permanent fit in an ally swingarm.
Sorry, no idea other than what this selection from the Hyperpro Catalogue / Range shows: The OEM rear shock follows the '+' mark.....If you go to the Hyperpro website, you can find the table in full; but you can see from this that Ohlins. White Power, Showa and Boge have been fitted at some time. Note that between 1990 and 1991, there is no mention of the very early SS which was fitted with a Marzocchi (which I assume to possibly be left over from the Sport??) 748 SP STREET `94> SHOWA+OHLINS SP-DU07-SSA008 SP-DU07-SSB008 SP-DU07-SSC008 749 `04-`06 SP-DU09-SSA020 SP-DU09-SSB020 SP-DU09-SSC020 750 `75-`85 SP-DU07-SSA011 750 PASO `88-`90 MARZOCCHI M1R 775 SP-DU07-SSA005 SP-DU07-SSB005 SP-DU07-SSC005 750 SPORT `89-`90 MARZOCCHI+ WP SHOCK SP-DU07-SWA003 SP-DU07-SWB003 SP-DU07-SWC003 750 SPORT `89-`90 MARZOCCHI FR+RE SP-DU07-SSA004 SP-DU07-SSB004 SP-DU07-SSC004 750 SS `91-`94 SHOWA+OHLINS SP-DU07-SOA001 SP-DU07-SOB001 SP-DU07-SOC001 750 SS `91-`94 SHOWA UPSD+SHOWA SP-DU07-SSA001 SP-DU07-SSB001 SP-DU07-SSC001 750 SS `91-`94 SHOWA+WP SHOCK SP-DU07-SWA001 SP-DU07-SWB001 SP-DU07-SWC001 750 SS `95 MARZOCCHI UPSD+ SHOWA SP-DU07-SSA002 SP-DU07-SSB002 SP-DU07-SSC002 750 SS `95> MARZOCCHI+WP SHOCK SP-DU07-SWA002 SP-DU07-SWB002 SP-DU07-SWC002 750 SS `95> MARZOCCHI-OHLINS SP-DU07-SOA002 SP-DU07-SOB002 SP-DU07-SOC002 750 SS `96> MARZOCCHI UPSD+BOGE SP-DU07-SSA003 SP-DU07-SSB003 SP-DU07-SSC003 750 SS IE `99-`02 SP-DU07-SSA010 SP-DU07-SSB010 SP-DU07-SSC010 M 750 `94-`97 MARZOCCHI+BOGE SP-DU07-SSA006 SP-DU07-SSB006 SP-DU07-SSC006 MONSTER 796 10 SP-DU07-SSA012 SP-DU07-SSB012 SP-DU07-S NB.....The main thing with the ally swingarm is to make sure the eye of the shock does not hit the lugs on the swingarm when the shock is twisted on it's bearings......that is why the Boge shock with the larger eye than the Showa should not be fitted to the ally swingarm, although some people have done it without problems....I just wouldn't take the chance. PS....The Hyperpro shock relevant to your bike should be listed here....it will be the second 'SP' reference for each model.
