Thread: Old Girl Sally is dripping blood!

Thanks Steve, will do. And I will bring the refreshments

1 -1.5 tho shoudn't need heat same size as OD of SS will give you room to clean up when you do your locker .Old spring not usable?

Noel

Hmm Noel great ideas

Old spring hit the garbage but I should check that option.
Other idea is I could head down to the "golden spanner" and scrounge through their inventory of 3567 Toyota seals and find a seal with a similar ID and flip the spring off that?

If I go with a sleeve your idea of keeping it slight oversize is a win.

Would you think maybe go even tighter than 1 thou and shrink fit for certainty?

Steve What ever floats your boat I would just make it a firm push fit with some locktite retaining compound my press fits are hit and miss these days

I haven't tried this but was told by my mate from Bruny Island, if you have a seal that has gone hard and has been disturbed, soak it in neat 'Engine Stop Leak', it should make the seal flexible enough to take up again.

Using the 'Engine Stop Leak' might be worth a try in conjunction with that idea of shortening the spring.

For mine, I grabbed a new flange from eBay UK that was up for auction for about a dollar, that let me off the hook of installing a Speedy Sleeve.

Hmm if only I had read that before having a play!

All is done now and Im about to head off - so far so good leak free but a frustrating day.
I perhaps tried to be a little too tricky and spent the time making a shrink fit for the flange.
Everything turned up very nicely and was looking happy.
Flange turned to 42.45mm, 4140 sleeve to 42.00mm ID (kept OD ~50mm for the fit)

I heated the 4140 sleeve up and then went to press it on and got all but the last ~3mm before my complete lack of machining skill showed itself! She bound up good and the press stalled out.
I used 0.45mm interference, after trusting the internets that assured me 20 thou for a shrink fit.
Clearly I didnt get enough heat into the sleeve or I should have gone less interference.

Anyways, it is never moving anywhere now! I final turned the flange to 48.20mm OD same dim as the speedi-sleeve and the seal by pure dumb luck sits beautifully on my poorly fit part. The test will be how it seals with a bit of heat in sally I guess?

I have some photos but am running out the door so will load em later.

Thanks one and all - was a bit of fun and I learnt some stuff for future projects.

When I did the sleeve for the LT230 (aluminium housing) I played it safe and went slip fir with locktite product. Perhaps this would have been safer but not nearly as educational.

Oh and I believe only 376,245 cuss words were harmed in the making of this part.

It's all good fun Steve. You never stop learning and hindsight is a marvellous thing. Have a good trip
