T6 Crankshaft seal replacement - a word of warning to the uninitiated

Hi,

Well being the new owner of a 2019 T6 Shuttle, 5speed with 41K on the clock, I knew it was time for a full service including oil and filters, cambelt & water pump kit, tensioner and aux belt in preparation for the next few years of travelling.

Closer inspection showed the crank seal was leaking so decided to do that as well.

I've done the cam belt on my golf and it was fairly straight forward so no major dramas anticipated. Work would be completed in my barn, no ramps or a pit, just trolley jacks and axle stands where required.

I wont dwell on the cam belt side of stuff, its been done to death here.

But for those, like me, who are not professionals, but have done a bit of spanner work, the word of warning is the crank seal. It requires removal of the main crank pulley, not a problem in its self. But when refitting, it needs to go back on and to be tightened up to 180 NM + 135 degrees. When the van is not on a ramp or over a pit this is some hellish torque for Joe Bloggs on his driveway to get that bolt too due to the difficulty of locking the pulley and getting enough leverage on the bar.

To cut a long storey short, I ended up having to fabricate a tool which I could use to lock the pulley, whilst I applied every ounce of strength and weight through some bar extensions till I eventually got there.

I'm only putting this up there so that you dont start off half cocked like I did at a weekend and end up wasting lots of time trying to do a regain, blocking other vehicles in etc, etc.

For what its worth I will post a couple of photographs of the kit I made, but similar stuff is on Ebay.

I know some will be laughing at me, but if you are in any doubt, that bolt requires some proper welly to get it torqued properly, give it some thought before you start 🤣🤣

No, the pulley came off far easier than it went on. I had another arrangement for the removal, but that just wasn't good enough to hold the pulley when the bolt was tightened.
 
Worth buying a torque multiplier for.
I've got one mate, and tried it. To be fair it's a very cramped space to set one up in. And you still have to hold the pulley. And keep the whole arrangement stable. Once I had made the tool to hold the pulley, I should have tried it again to get the 135 degrees.

I’ve been in similar situations (non auto) where I’ve drilled the end of a spanner, fitted a shackle and used a chain hoist to get a fastener torqued. It needs perfect alignment and a solid anchor but it’s doable.
