Hi David,

This the information will help a lot. As far as I can see I have the
same steering box as in the article.

I thank all forum members for their help. I am now aware that
a hard job is waiting for me next winter.

Dear Readers,

Please be aware of the dangers of misunderstandings here. From 1926 to around 1931/2 Lagonda fitted the "vintage" MARLES box which has a roller which can be adjusted to take up the play. From then until 1938 when the LG6 came out they fitted BISHOP CAM which uses brass shims to adjust them. This is what I have on my 16/80 and M45. I bow to superior knowledge that they then went back to MARLES for the LG6 and the V12 but it was a different design that I believe also uses shims to adjust it.

I followed up what happened to Marles boxes post war and they were the preferred choice for things like dump trucks when cars went over to rack and pinion.

Readers, feel free to correct me if I am wrong, or endorse my thought s if you think I am right.

Cheers Colin M34

Hi Colin,

Following your comment I conclude that my 1931 3L has a
vintage Marles steering box with a roller. Do you adjust the
play in the same way as mentioned, or is it different?

Hi Fred,

Yes this is how you adjust it. Once you get access to the roller, it's only about a 15 minute job and very satisfying! You then have the boring job of assembling everything which always takes twice as long as dismantling!

Hi Colin,
Yes, I recollect the guy at Steering Services saying that we had dump trucks etc to thank for the continued availabilty of most parts for the Marles gear (as fitted to LG6 & V12 anyway).

I've managed to find my set of Newnes...it's actually titled "Motor Repair and Overhauling". The Marles boxes are covered in a general chapter "Steering Gear"; you may be interested to know that there is a separate chapter solely concerned with "The adjustment and repair of Bishop steering".
