Hello,

further to my recent post (which battery?) enquiring as to which aftermarket battery is suitable for my 2001 TDM 850 and noticing that there is some ambiguity regarding the battery type, I thought it was sensible to remove the dead battery first and check the model before ordering a new one.

But hey, surprise surprise, this does not seem to be as easy as I thought it might be.

At first I thought it would be possible to remove the battery from the top by removing the front side panels, fuel tank and fuel hoses. However I noticed that there is a further device sitting just on top of the battery with a load of different cables and hoses (is that the charging system or electric fuel pump??) which would be impossible for me to disassemble especially since I am doing all this work on the pavement outside my house.

The TDM-Haynes manual that I am consulting suggests that I can remove the battery by simply removing the cables from the frame and starter relay and sliding the battery box out from the right hand side of the shock absorber. I tried doing that. First of all I noticed that it was impossible to manoevre the box around the shock because part of the rear break piston was on the way. I removed the two allen screws holding the piston in place and this gave a bit more room. I managed in this way to bring the battery box all the way to the right hand side of the shock so the long side of the battery is now parallel to the long axis of the bike (in other words the insulating cover that looks like tin foil is now facing the right hand side of the bike instead of the front). HOWEVER, it still seems impossible to get the battery box out of this space. There is the rear plastic mudguard that prevents any furher movement to the back and also the "ears" of the battery box (where the retaining screws go) obstruct any upwards movement where other electronic components sit under the seat. So I am in deep sh*t, with my battery box leisurely standing on the right hand side of the swing arm.

Seems like some sort of karma is getting back at me for insulting Yamaha Service centers in the past

Do you have any tips to offer on how I can get out of this "tight" situation? Has anyone been successfull in doing this before?

If you have no center stand place a trolley jack under somewhere and lift the rear wheel off the ground. Remove shock. Remove battery. This could be a little precarious so I would recommend having someone stand by just in case.

A friend of mine says he managed to remove the shock and battery just by leaning the bike over on the sidestand and holding it against himself. I would have liked to have seen that.

Ok ok, so this REALLY isn't as straightforward as I thought or the Haynes cr@p manual suggests (it never mentions having to remove the rear wheel).

No I don't have a paddock stand and even if I get one I think these jobs require a garage or shed. A pavement in London with rain starting and stopping at random can't be much accomodating.

Ok ok. So considering other options now....

Would a battery charger be able to charge my dead battery enough to start the bike up or is a dead battery really dead dead ?

DONT take the shock off...Idid it this way first time...BIG mistake.bike on paddock stand grabrails tied to roof of garage cos the bike will colapse when shock is removed.it does come out with the shock in place.If my memory serves me i think i managed to get it out on the LEFT side.Iknow haynes say right but obviously thats not working for you.the bottom shock bolt has a tendacy to seize in place aswell.

I took the tank off and got mine out through the top, its a tight squeeze but it came out.

Easy way I found to remove battery on MkII is remove RHS rear peg hanger, rear brake lever and losen brake piston from frame. remove battery cables from relay,unscrew battery box screws, battery slip out on RHS of Shock. Can be done when bike is in side stand.

Hmm this kinda sounds promising, thanks DaveB . I will give it a go tomorrow.

I did it bondy's way - also loosened off the wiring loom clips behind the tank. No rear wheel/hugger/shock to remove but then again there's no electric pump on the early mk2

Always managed to get battery out as described in the Haynes manual. Its a bit of a pain takes a bit of manouvering but persistance usually pays off. I always dismount the brake piston but also the bolts holding the brake pipe guide. The rear hugger is held in place by these bolts and removing them lets you push the hugger out of the way and give you some extra room. Hope this helps.

Success!!
Managed to remove the battery by removing the rear peg hanger and the brake pipe guide. After that the battery comes easily out of the right hand side. Very useful piece of advice, thanks to all of ya and especially DaveB.

Glad to help,
