Clutch replacement 870 without help

[Tanker93]

Dunno about everybody else but I used a old input shaft as an alignment tool once and will never do it again. Reason being the part that runs in the spigot bearing is always worn and it caused the clutch plates to be misaligned and then the new shaft wouldnt slide in.
I always use to bolt it to the flywheel first and use a proper dummy tool but now prefer to sit it on the input shaft and button it up after putting 4 or 5 bellhousing bolts in (if theres any issues you havnt got too much to get the box back off).
When installing the box, if the top is touching but the bottom is still a way off (or vice versa) dont try and pull it in with bolts as the housing is only aluminium. Keep playing with the jack settings till its pretty much flush. And like another user said, just run all the clutch bolts in half way first, then go back around once or twice with a torque wrench. The first one can sometimes be a little tricky but if you hold your tongue the right way you'll get it and the rest should be easier.
If its your first time then definitely make sure you've got a torque wrench for checking all the bolts (ESPECIALLY the drive shaft and clutch bolts). Using a torque wrench is actually easier when doing alot of things imo as you wont second guess yourself as to whether you could maybe do something a little tighter or if you're doing a bit too tight.
