Hi Lawnies. I got a Marquis 18" recently in AFAIK original good condition cw BSA sloper sweet runner (not like the lumpy BnS)
So Imagine my surprise when I came across nominal 5/16 BSF bolts with non standard threads (ie 24 tpi instead of 22 ca 3" long). I thought I must have gone hayseed and spent all day cross checking this
Has anyone heard of this?
It refers to the Bolts that adjust the bottom blade clearance with the cutting cylinder and also the bolts that hold the front roller adjustment. Thats all I found so far - will I find anymore? Its a bit worrying if this is a feature of Ransomes alleged engineering excellence
I will be changing these out for std BSF and stainless is readily available today. Will post some photos
In all my engineering experience, I have never come across an oddity like this?
Having said that, if you ever had the misfortune to encounter a British Leyland vehicle you will know about their dirty tricks. I had a horrible Sherpa van once for my business. Its radiator failed (because it was poorly mounted and suffered from chassis flexing) so I went to the scrap yard. The fella told me he had some radiators but couldnt guarantee they would fit. BL would deliberately change the mounting holes and spigots every year for no reason other than to spoil the scrap trade. It took me a whole afternoon drilling new holes to fit. A nasty job. I scrapped it after its king pins failed the MOT and the man said its often impossible to replace them as they seize up. Deliberately planned obsolescence
