fitting adjustable cam gear - question

[blackS2]

trying to fit repos adjustable cam gear (chain) on camshaft I have a question...

...it seems to be, that heating the ring from the camgear up to 170°C (oven) is not enough to get the ring on the cam - it is still to small...

...so here is the question - how much temperature is needed/allowed to fit it...

or do I have to use a blowtorch??

thx...

oven normally works, you can also put the cam in the freezer

I used a press to "pop" mine off...oh and some heat to help it on its way!!....

I used a gear puller to separate it from cam... no problem... but fittig the new gear seems to be not so easy...

Cam in the freezer. blow torch the pulley. should fall on.

Ok thx...

I also found a description from an old VAG service manual for shrinking spur gear... heating 200 max. 240 deg C ... at 220 deg C - 6 seconds time to fit...

..I will try again...
