MG Midget and Sprite Technical - Propshaft Greasing

I am having difficulty greasing my propshaft (exchange from Moss) the guns that i have (Wanner - very high pressure and a small unit that you have to hold on - not clip onto nipple) both cannot get into the restricted space between the yokes. Tried turning prop around etc.

Is it a case of incorrect length nipples supplied - I've just rebuilt my spare shaft and same problem. Can't remember this problem on old my midget i had in the seventies.

I don't like sealed for life as they can only contain the same quantity of grease, as they also have to be assembled into the yokes.

I seem to remember years ago when i helped out a friend in his garage he had a gun with a needle or 'V' point that went into the centre of the nipple - are these available ?

I had exactly the same problem when I renewed the UJ's on the Frog. In the end I simply reduced the diameter of the nipple connector with a hand file and it went on a treat. So check the wall thickness and I imagine you could do the same.

You can also buy a long grease fitting, install it long enough to grease the joint, then put the short one back in. Yes, it is a pain, but not as bad as replacing the u-joint...

I use a replacement flexible pipe on my Wanner because of this problem (mine was accessing nipples on some of my front suspension but the prop nipples are just as big a bugbear)

the ends can be carefully "tapered" to give easier access, too

The replacement came from the tool department at Halfords and is packaged as Draper, direct unscrew/screw neww one in. It took three minutes or less.

And it clips nicely onto the nipple ends from most directions

Richard, are you referring to the Sellarc greaser?

This problem arose when trying to grease the nipples on a Morris Minor Centre propshaft supplied for a Sprite 'type 9' conversion. The broad head of a Wanner grease gun would not enter the Vee of the prop joint to seal around the grease nipple. I had some extended grease nipples that are, perhaps 1/2 long. I had to recut the threads to, I believe, 6.00 mm to be able to screw into the U/J. After fitting and application of grease to the U/J I have, to date, experienced no problems.

Mark,

That looks like it - think it had 'Castrol' badges but probably the same unit. Looks a bit large for my restricted garage !! Wish i had more space!

Have been looking on the 'net' and some 'pointed' ends are available to thread onto an extension that may just get in there between the yokes - has anyone tried these - seem to be threaded standard BSP.
The pointed bit displaces the B/B in the nipple and allows the grease past etc.
