Roll Pins


Go to solution Solved by Sparky,

Recommended Posts

Hi Chaps

Its a sunny Sunday morning so i thought i would remove the engine and gearbox.

Two hours in and every thing disconnected , except the roll pins  on the drive shafts. Question is they are in there good, how much force do i have to use and what's the best tool / kitchen implement  to use ?.

Every thing else came apart easily ( too my shock/ joy)

Your joy could very quickly turn to pain if you jam something in or snap something off in those roll pins,  use the correct sizes of punch. Separate the driveshaft yoke only as a last resort.

If the driveshafts aren’t leaking, or you’ve had problems with them in the past, you might want to split them at the inner yoke and leave the output shafts in place. That way you keep the integrity of the seal. You need to release the rear lower link arm, get underneath the car and push the hub out with your boot. Reinstall in the same way. I’ve done this four times now, and I wouldn’t remove the output shafts.

If you do decide to remove the driveshaft pins, it's a good idea to punch them out in reverse.  Determine which side has the witness marks from the installation and punch to remove from the opposite end inner first and then outer.

Roll pins come out only if absolutely necessary.  For engine/gearbox removal I always separate the spider and yoke.  Couple of minutes of very simple work.

Already summarised by @Chillidoggy above; the driveshaft simply pulls out of the yoke.  Undo the inboard rubber boot first, be prepared for some grease loss and keep things clean.  Quite simple if lower arm inboard is released.

If I may just add to the my learned friend's post above, a plastic bag secured with a cable tie over the end of the driveshafts and the yoke cups at the gearbox, will keep them all clean. If you need to move the car, pop the lower arm bolt back in temporarily and tie the driveshaft up with cable ties to the top arm pivot, or any convenient point.

On the contrary. The majority of Sparky’s best posts have been made under the influence of alcohol.

Hi all

Still struggling to remove the drive shafts, as you can see by the image i am nearly there but cant push the hub out any more to release the spider from the joke.

I have released the lower arm only?

If the bicycles are taking over the shop, where are the motorcycles?

Wish my engine was that clean coming out...

The bicycles are all electric, its the future. I have done over 2000 miles on mine in the last year. The motorcycles are in my other garage.

I am going to try and get the engine a bit cleaner, i like the idea of having the charge cooler and cam covers powder coated.  

The gearbox needs a good clean, if any one knows what to use i would be interested to know

Dunno - Nobby had some special magic stuff - some aluminium cleaner.

but - when you clean anything it doesn’t stay shiney and clean for long unless you obsess over it. If I was going again - I’d just use a steam cleaner and detergent.

Only here once
