Alanretired Posted February 19, 2023 Report Share Posted February 19, 2023 Hi. I have read the forum's posts on the effectiveness of the Revington spring loaded steering box top cover. In general it seems beneficial but some owners find no improvement and revert back to the standard adjuster. I would like to try the Revington fix on my 1958 Tr3a. Has anyone got a redundant spring loaded top cover that i can try or buy. Regards Alan Quote Link to post Share on other sites
Lebro Posted February 19, 2023 Report Share Posted February 19, 2023 No, but I can recommend them. The trick is to adjust the peg as normal, leaving just the tinyest amount of "spring effect". The y will make no difference when cornering, as the peg is already hard up against one side of the worm slot, the big difference is when going straight ahead, the sprung loaded peg removes all free play in the steering box. What it won't do is improve the steering if you have free play anywhere else, eg ball joints, & play in the drop arm bush at the base of the steering box. As it happens I am in the process of switching to rack & pinion, but not because of sloppy steering, I want it to be lighter. My entire steering box (with sprung loaded peg) will be up for sale in a few weeks, but I would probably not separate the top from the rest. Bob Quote Link to post Share on other sites

If you have the other Revington mods, new pins plus a bushed idler and modified link arms to correct the Ackerman angle you end up with very nice very positive steering. All assuming the worm is not damaged and the pin has not worn badly. (Pin can be rotated 90 degrees to take out wear.) Iain Quote Link to post Share on other sites

Iain I'm glad you said that about the pin Iain, it was a dodge we used on vintage cars. When I was adding the penrite grease, I did exactly as you suggest and it took a 2 inch play at the wheel down to less than half inch! I was thinking about the revington cover, but happy with my results so far! T Quote Link to post Share on other sites
BlueTR3A-5EKT Posted February 20, 2023 Report Share Posted February 20, 2023 (edited) The MG T Type drivers have been doing a mod on their steering boxes for 60 plus years. There is a kit called the Tompkins kit but I have never seen one in real life and am struggling to understand how it works. They mention it overcomes the excessive friction. In which case that is not our issue here. They also fit a grease nipple to the filler plug/bolt and fill through that. https://www.ukmgparts.com/userfiles/pdfs/tc1.pdf Edited February 20, 2023 by BlueTR3A-5EKT Quote Link to post Share on other sites

I will order a sprung steering box cover from Revington and see for myself what difference it makes to the straight line performance. Regards Alan Quote Link to post Share on other sites

Lebro Posted February 23, 2023 Report Share Posted February 23, 2023 That is the standard set up, sprung version has much larger size adjusting screw, & locknut Bob Quote Link to post Share on other sites
