brian-nz Posted December 30, 2023 Report Share Posted December 30, 2023 Hi All and Happy New year I currently have the front apron off to fix a cooling issue and thought I should try and fix the steering box oil leak. So I ask for your guidance - Can I change the seal with the box in situ. Looking at the box it seems that I could remove the drop arm and slip off the trunnion by undoing the bolts. Is the seal pressed in place and also can the bush be changed by this method Thank you for your advise in advance Regards Brian Quote Link to post Share on other sites

Lebro Posted December 30, 2023 Report Share Posted December 30, 2023 Removing the drop arm could be difficult in situ as the arm is usually very hard to separate from the shaft. Bob Quote Link to post Share on other sites
RobH Posted December 30, 2023 Report Share Posted December 30, 2023 If wear in the 'box is not an issue, just a small oil weep, you could change to one of the semi-fluid greases like this Penrite one. https://penriteoil.com.au/products/semi-fluid-steering-box-grease Quote Link to post Share on other sites

Slow to fill though worth the effort If you feel the rest of the steering box needs restoring it is best to remove it entirely rathe than grovel about doing a fraction of the task. Replacing the drop arm bush means pressing it out, a new one back and then reaming to size. Fit the seal last and protect the inside of the seal lips from the sharp edges of the drop arm spline. They will cut it otherwise and perhaps cause a leak. Do not hammer the drop arm in situ. You may chip the worm. RH helix worm is for RHDrive TR. Quote Link to post Share on other sites
iain Posted December 30, 2023 Report Share Posted December 30, 2023 Agree it’s slow to fill……best done after a good run, let the engine heat sink into the steering column, then use warmed semi fluid grease. Quote Link to post Share on other sites

I fitted a grease nipple to the top of the box (In the centre of the usual fill plug) and and have a small grease gun filled with the thicker Penrite oil. It can also be used on the front suspension trunions. Charlie. Quote Link to post Share on other sites

brian-nz Posted January 4 Author Report Share Posted January 4 Hi All Thank you for the responses and advice. As there is not much play in the steering I think I will leave it alone. I have purchased the Penrite grease and will live with any leaking until absolutely necessary. At some stage may look for another box to renovate at my leisure so will have a backup.
