Who mentioned on here that they had bought a flywheel locking tool, i am sure e bay was mentioned but i cannot seem to find it ?
Cheers Jim.
 
Have seen on ebay (US)

This is US too - http://www.arnnworx.com/catalog/index.php?main_page=product_info&cPath=65&products_id=183&zenid=91532b0c63cedd64e2010631fe196cab

However low price may mean you don't get hit import duty - from memory you don't if it's under £35 but I could be wrong!
 
Frenchy, my young lad ordered one from arnnworx last week, its in transit. I got stuff from them years ago, no problems.

Check out this nice bit of kit from the US : http://www.ebay.co.uk/itm/Porsche-944-951-Engine-Overhaul-Tools-/200681527891?pt=Motors_Car_Truck_Parts_Accessories&hash=item2eb98d1a53

No need to take the starter off .
 
that piston tdc lock is brilliant such a simple idea to a pita job removing the starter!

Does anyone have any worries about this tool before I run out and buy one!!
 
I find that really scary at face value, without further details. How does that gadget work then? I would be horrified to find that you remove a plug and jam the piston some how
 
I really don't like the look of that 'alternative' lock that jams the piston in place. The torque required to undo the front bolt is quite significant... why take the risk of putting a hole in one of your pistons to save 15 mins removing the starter?
 
I made my own flywheel lock which is reversible so does undoing & tightening-made a pulley locking key from a disc grinder spanner by slitting the throat of it ,adjusting it so that the pegs fit the pulley ,then welded up the slit & an adjusting spanner from an old Atco mower spark plug spanner again by slitting it to size.
The ratio of the flywheel locking point radius to the possible slight offset of a crankpin at TDC leads me to conclude that the load on the piston will be rather large-& having used a extra long bar to undo & then some ,the crank bolt several times ,I'd avoid this method.

As I thought. The piston material is malleable even when cold so considering the torque necessary to undo the crankshaft nut that is a stress that I would not put on the crown of the piston. It is not generally appreicated that an indentation could be put in the big end too. When we were torquing up beetle flywheels to 217 lb/ft we were told specifically not to use a flywheel lock but a peice of angle iron across two clutch studs, or we would put an indentation in the rear main bearing. The piston jammer does not spread the load out across all five main bearings but instead loads up one piston and one big end. I shudder at the thought like Sideshow Bob when he steps on all those rakes.
 
Cheers Peeps,
A flywheel lock for me everytime, t'other gadget is asking for trouble IMO [:eek:]
 
I can hardly believe anyone would seriously wind a metal stop into one spark-plug hole and put such torque on the crank......the threads were never intended for that purpose.
 
I bought a flywheel lock from Porsche can't remember the price but around £20 rings a bell.
 
Colin, can you have a look for a part number on the fly wheel lock you got from Porsche ?
 
Its Porsche special tool no 9206.. Do you want one to keep or is it just to use for a job? Cause you could borrow mine if you want.
 
thix is it

Thank you for the offer Col, should i get stuck i would take you up on that, ideally i want one to keep if they work out cheap enough, looking at that though it would not be a big job to get one knocked up.
Think about renting that out with a view to a deposit being able to recover a non returned item, will call OPC for a price the morrow.
 
Ordered from OPC Kendal today via Jonathon (Top Fella) i think it was £32 plus the usual, 220 will be getting new belts over the winter months.
