Gearbox oil change

[Lebro]

Decided it was time to change the oil in my '3 partly because I had 20W50 in there, & the consensus seems to be that a proper gbox oil is better, & partly because I have not checked the level since filling it in 2013.

 

I was a bit worried that I may have TRouble undoing the large brass overdrive drain plug / filter housing.

I need not have, it was barely finger tight (Thank you Hardy Enginering)

 

Well 1.8 ltrs came out of the two drain holes, so I had not lost any significant ammount.

 

I was almost on the point of making a tool to do the big brass plug up again when I had a thought.

At last years CC show I purchased an oil filter removal tool (to complement all my others) & it was the sort with three gripping arms which pull in as you apply torque to the ½" drive. It worked a treat:

 

 

Because my box is from a TRiumph 2K it does not have the filler hole / dipstick on the top, it has to be filled from the level checking plug in the side of the box. This was going to be hard work, so I found some plastic pipe which fitted snugly in the side hole, & also fitted nicely over one of my funnels. Fed the pipe through the gbox cover top hole, resting funnel on top of the door, & poured in (slowly) the required 2 ltrs of Penrite GB40. All went well & not a drop spilt.

 

Then since the car was up in the air anyway, I changed the axle oil, & then greased everything including both ends of the propshaft.

Todays job just to finish off is to check / adjust the brakes, & front wheel bearings. (but only after an oil + filter change on the wife's Sceicento)

Good one Bob ~

 

I'll do the same on my 3A when it's time.

 

Thanks ~

Bob, I find a 2-5 -2.75" 'C' spanner ideal to remove/replace the A Type o/d drain plug.

It depends on how tightly it has been done up. The "C" spanner is only pulling on one of the notches, but yes, I used something similar to remove mine, but as I said it was not tight at all.

ORS actually do a tool to remove them, not cheap but perfect fit https://www.overdrive-repairs.co.uk/cart.php?cat=A%20Type%20Spare%20Parts%20List&id_prod=132.

Bob,

 

Good idea, I have one of those oil filter removal tools, but there isn't room to fit it onto my oil filter so I use a strap wrench instead.

 

And I picked up a C spanner from an auto jumble that fits perfectly, so now I have two means of undoing the filter cover.

 

I also have 20/50 in the gearbox / overdrive that I will get around to changing in the winter.

 

But even though mine is a saloon box, I replaced the top cover with one from an old TR box that came complete with overdrive switch holes and a dipstick hole so I can pour the oil in through the dipstick hole.

That's interesting, I had wondered if they were interchangable. I presume it was a 4 synchro doner box ?

I know you can buy them, but too expensive if seldom used, I can see why you would need one though.

I was going to make one like that but then remembered I had the filter remover.

Had the filler issue when I was fitting the Stag box in my TR3A. I spent a happy evening drilling the top cover to accept a dip stick. the casting mark of where it goes is on the top cover.

These are nice but not cheap.

Looks good.

ORS were selling their overdrive drain plug remover for £20 at Lincoln.

 

I agree with Stuart, not cheap, but it's definitely the right tool for the job.
