Tips on removing speedo gear

RodneyA · May 19, 2014

I've nearly destroyed the lip on the speedo gear housing trying to remove it, it won't budge or even move at all, trying to get it to turn but no luck.

It's been soaked in WD40 for the past 2 days and I'm now stuck and looking for tips on removing it.

A wee picture.

they can get very seized ,in which case removing the complete output housing is the best bet and lever/knock out from the inside

I've had a google and seen mentions of a front and a rear output shaft, do I just need to remove the rear one? If so is that removed by removing the bolts in the pic to the left.

Ring of bolts as the output shaft is splined you may find it easier to undo output shaft nut and release output flange as well.

The output shaft has speedo drive and spacing collar behind output bearing(bearing held with circlip)- hopefully it will seperate

Do I need to drain the box?

Yes

I drained the box and took off the rear prop, I just want to ask some questions first,

I presume I take this big bolt off, I think it's a 32mm one but I'll have a search and find out the correct size.

Do I then remove these bolts, I think there was 4 of them.

Does the box just separate and slide off from this part here?

Woohoo, got the little devil out

Took the read output shaft off and was easy after that, some of the cog is damaged.

Now I'm thinking Maintemance while it's off,

There is a little bit of movement in the shaft and can wiggle it by half an inch, so I'm thinking it's best changing the bearing also, new oil seal, circlip and oil shield output flange, and a new gasket Ofc,

doesnt look like you change the oil often enough

RodneyA · May 20, 2014

Hehe, I've not drove it since I bought it last march

it requiring a lot of work for me to even think of putting it in for a MOT Last owner didn't maintain it.

RodneyA · May 20, 2014

The oil is stinking. Is there anything worth checking in the box, I read that there is a bearing also that can go, not sure how to check it tho.

you could drop sump plate and feel foe end float in intermediate gear (middle one)and adjust outer nut to remove any if there is

RodneyA · May 20, 2014

Silly Q but what is end float, movement?

jamesmartin · May 20, 2014

yes ,box apart from the 2 output bearings uses taper roller bearings which should have no movement ie gear should rotate but not move endways
