Fan Removal

I'm taking apart a type 3 engine but cant work out how to remove the fan? My manual helpfully skips over this part and I'm having trouble searching for a related topic (internet is dominated by type 1 engine info).

Is it screwed onto the crankshaft or just held on tight?

get 2 x 8mm screws or bolts and screw these into the 2 appropiate holes around the hub section area this will push the fan off give it a pull as well wriggling

Actually the 2 x M8 tapped holes were to attach the fan puller, not push the fan off. The fan puller was a piece of around 10 x 30 x 120 steel plate with clearance holes each end to suit the M8 screws. A central hole was tapped (around M12 or M14 fine pitch) for the puller bolt. The end of the bolt had a freewheeling pad which contacted the end of the crankshaft. Not that the fan is tight but needs a straight pull for ease of removal.

I have one "somewhere in the shed" but as it hasn't been used for 8 years it seems to be hiding.

put the bolt back in a few turns (far enough so threads dont get damaged ) make up a flat plate or 6mm angle drill 2 holes for the 8mm bolts so thread passes thru then screw them into fan evenly to pull the fan off , may have to loosen large bolt if it hasnt free'd of the crank enough , works every time with no damage.
it helps to run a tap thru the 2 threads in the fan first.

hi mate, i actually did mine in the car (first time) not knowing how easy it is to get the engine out. if you try to push it off with long bolts you will damage the housing, i know this. i bought a super cheap puller kit (eg holden harmonic balancer type) about $15.00 on a sunday afternoon!!!! always the most inconvenient time to be doing a job like this and it worked a treat, just remember to protect the crank internal thread at all costs by using a socket or something to push against. have fun retensioning the pulley bolt if it is in the car. the 2nd time was much easier with the engine out and using a flywheel lock to retension that bolt. best of luck.

thats why keeping the bolt in the crank and using the plate method you push against the head of the bolt. And go nowhere near the case

The same as most of the other bolts on the engine........ clutch bolts, crank case bolts etc, standard metric coarse M8 x 1.25
