Simple engineering solution?

That is one big hydraulic puller! Made a mess of the pulley though, eh?

[Neil MG]

Though it was combined starting handle and rollover jig...

[linearaudio]

Probably made a mess of the internal crank thread as well......

[Trog]

The damage was a result of following Mr Haynes words agian having bent all the teaspoons in the kitchen I took out my frustration with my adjuster tool (hammer ) A socket in the hole should have saved the threads but I think the crank might be a couple of inches shorter!!!! Why are the things on so tight?? and how do you get them off without damage

[bmcecosse]

I've never known these to be any more than 'hand tug' tight..........

[1mustard]

no nor me, however if things are that tight gentle levering with a pry bar either side behind the pulley, ding it softly with a hammer and it should come off, failing that a little bit of heat normally helps but will damage seals.
This is a problem on modern engines when you don't know if theres a sensor behind the cover! also no woodruff key on the crank!

if it is was anything like the one fitted to my twin cam engine the last person to put it back on decided to use something like thread lock on the taper so it was stuck true and proper..

------how do you get things off without damage? By maybe not using a hammer?

[Trog]

Shrink £75 per hour, Morris and adjuster.......

[wickermonkey]

I take it the hydraulic puller was broken and thats why you were using a pair of stilsons (sp) on the end

The materials can cold weld after many decades under load.
Most of mine have come off after a few taps in both directions, but some have been a nightmare.
I've done a similar heath-robinson set up when my 3 leg puller wouldn't hold the pulley flange. I protected the threads using the bolt...

[Ratbag]

Mine was loose & just pulled off, admittedly after leaving the big adjustable on the nut after turning the engine over by hand. Found it when starting.... no damage other than the nut undone & pully loose!

Hello Charlie,

"thread lock on the taper so it was stuck true and proper.."

Tapers are always tight to spilt whether thread lock has been used or not. Often a puller and a hammer to shock them apart is the quickest way, but making sure that the pull is placed where there is no risk of damage to the pulley. I'll drill and tap two holes if the item is fragile so as to pull on the solid hub.

Use a slide hammer utilising the two drilled & tapped holes for purchase.

"thread lock on the taper so it was stuck true and proper.."

It's not a taper. Just a straight fit. I always put a smear of oil or copper grease on the mating faces to ease removal in future.

As for getting them off in the first place, i've destroyed a few myself...

[bmcecosse]

Pretty sure there are no drilled/tapped holes in a standard pulley....

[Alec]

Hello Chris,

the reference to a taper was an earlier post regarding a (Fiat?) twin cam engine, not a Morris engine.

[WHOOSH!]

WD40 and plenty of gentle coaxing doesnt work anymore? What has this world come to...

[bmcecosse]

Probably because WD40 is NOT a release oil......
