Flywheel nut torquing

[beepbeep]

I've decided to replace the crank seals while I've got the transmission and clutch out of my WC51 so I've removed the flywheel for access, anyone got any tips for how to torque the nuts up when I come to refit the flywheel?

Hi Chris,
its damn near impossible to torque the flywheel nuts with the crankshaft in the engine. However tool companies like Stahlwille and Facom do make very short open end spanners with 1/2" square drives to allow the use of a torque wench. Remember that this extra length will change the effective torque so you need to lower your wrench setting by approx 5 ft/lbs. I suggest you torque the flywheel nuts with No4 bearing cap removed, given that your replacing the main bearings.
I have tried to find a crows foot spanner to do this job without success.

Can you not just use a flywheel holding tool? Summit has them for $20. Some guys on V8 engines bolt a piece of scrap from an inspection cover bolt hole to engage the flywheel teeth; maybe you rig something similar.

Thanks for the replies guys. Adam, I've got a flywheel holding tool, great piece of kit but the problem is access, the nuts face the engine block. Ian, thanks for the heads up on the spanner, I'll take a look.......although I don't know where I'll find a torque wench, we haven't had wenches in England for a long time

just as tight as you can get them. there is an actual wrench for mopar flywheels they used to make. I saw one on ebay recently. its just a really long wrench. The standard length wrenches are just the perfect length for scraping knuckles on ring gear teeth. ;/)

That's what I was thinking, a long wrench.....so it's common on Mopars to have captive bolts with nuts on the rear of the flywheel?

They are D studs with nuts. they were all this way I believe. some had less studs but all the truck engines had 8. I think the V8s were the same way until a certain year.

Hi Chris,
we were in England in 2016 and there were wenches everywhere, you really need to open your eyes bonny lad

Chris,
google "crowsfoot wrench" and you will get a whole bunch of hits. Sulco, Williams, Snap-on all make an example.

I have thanks Ian and I've found a full set for a reasonable price on eBay

Thanks for that Kaegi, unfortunately with shipping and taxes it comes in at $55 and the dollar is up against the pound so I'm going to pass......but, I've found something similar in the UK called an aviation wrench, same length only metric but it measures .629" against a 5/8" .625" so I think I'll get away with it......thanks for the link
