Slack in Steering Gear - Super A

I have about one-quarter turn play in the steering wheel, chasing the front wheels. Shaking the steering wheel shaft, there is sideways play plus rain busily runs down into the steering gear unit and dilutes the oil.

I see there are 2 pre-sized bushings - one for the worm shaft and the other for the [vertical] sector shaft. a. Are these bushings still available? b. Would changing the bushings [plus accompanying seals for the rain] fix the slack steering problem?

Manual says Steering Gear Unit can be overhauled without having to prop up engine and remove entire front end.

Otherwise, it is that major operation and carry the Unit down to my Friendly Local Machine Shop.

The "Search" function is down for maintenance, so I may be repeating an existing Discussion Post.

Thanks in advance, for your help.

Yes, Don, I would sure appreciate hearing how your rebuild made out. I had missed that C-clip in the diagram - will get all the bits and check it out.

In 1976, I was home from sea and helped my Dad rebuild the Super A. Although he was also a skilled machinist, he hung off doing the steering gear, probably didn't want to have her laid up again.

I have inherited the Super A - its is a family heirloom, and I need a machine for out in the country here..... My brother has great mechanical skills so he got the 1933 Lagonda 16/80 2-litre 6-cylinder roadster with Van De Plas body - suitable for Vancouver where he lives [it's a car ! ].

Anyhow, I have been haunting the Posts and the Archives for much usual information from all who have so freely contributed; so I will soon be able to have the Super A out chugging again.
