Hi all.

This is my first posting, having purchased the 1972 700 from my neighbour.

I am in the process of rebuilding and i need to replace the rubber boot that covers the entrance to the selector housing. To do this I need to remove the flange in orde to get the new boot on. Problem is it will not budge. I have tried heat and a gear puller but to no avail. Any ideas and yes I have removed the rivet pin.

Cheers

Doug

Hi Doug, welcome to the forum, to replace the rubber boot ,you will have the remove the cover from the top of the selector tower to get access to the pin that holds the rod with the flange. I'm not sure if you can access the pin with out lifting the body. I have attached a photo , the pin is the one that attaches the finger as well.

Might it not be easier to remove the long gear change rod from the "finger" that sticks out of the tower? I didn't quite understand the original question (i.e. what the "flange" is), but if you can undo the rubber boot there is a single bolt that connects the long rod to the "finger"; undo that, push the rod forwards and swap the boot for a new one.

Doug, welcome to the forum! Where are you based?

Hi All,

Thanks for the replies. I have removed the long rod (3 foot?) that runs from the gear stick to the flange that connects it to the selector mechanism. This was connected by three bolts to the round flange. The flange sits directly under the rubber boot and in theory is connected to the selector by a small rivet pin which I have knocked out. I was hoping that a gear puller would allow me to pull this flange off but even with heat it won't budge. I guess I will have to try and knock out a pin from the mechanism that sits under the cover to the selector housing.

I spoke to Dale at Haflinger Technic and asked if there was a split rubber boot available that would which would seal a long one side but unfortunately not.

I am based in Lot et Garonne in SW France. I bought the Haf recently from my neighbour who sadly passed away in January, he had bought it in Paris 18 months ago.

Best

Apologies,

Forgot to mention that I have removed the platform for a spot of welding

Doug, I now see why I was confused by the original question; the only serious work that I have done is on my 1962 Haf, and the long (3'?) rod on the early Hafs does not have the flange with three bolts - it is just a long straight rod. But having looked at a later Parts Manual I can now see what your problem is.

Doug,

I have pulled off that flange you mentioned about two weeks ago from my gearbox. I had the same probem that you have now, it wouldn't come off, even though I had removed the pin. Finally, I removed one of the pins in the linkage inside the gearchange housing (shown in Dave's picture). Then I could properly work on the flange and remove the flange from the shaft. I think that the flange is a tight fit on the shaft and/or corrosion was a problem.


Kind regards,
Constantin

Hi Constantin,

Thanks for your response. I suspect there is some electrolysis between the alloy flange and the steel shaft. Did the pin inside the housing come straight out for you or was it a problem?

Hello,

the pin inside the housing came out easily, since it was always well greased. However I must say that I had already taken off the whole "tower". That means I could partially take out the selector mechanism, so I had a bit better access to the pin.

I don't think that the flange is made of alloy. I think both flange and shaft are steel.


Kind regards,
Constantin

Hi Constantin,

I had thought about removing the tower but access to one of the securing nuts looks a little tricky, how did you find it?

Did you split the mechanism at the flange afterwards?

Cheers

Doug

Hi Doug,

I was able to loosen all three nuts with a slim extension for the ratchet. Possibly I have also removed the two steel plates in the middle of the housing in advance. If you want to remove the upper gearchange housing, you also have to open the small lid a bit further down on the gearbox to loosen and remove more parts of the selector mechanism.

Yes, I split the mechanism flange afterwards. I was able to punch the shaft out of the flange.


Kind regards,
Constantin
