Crush washers

[Toltec]

Does anyone know where I can get crush washers for the gearbox drain plug please? Rimmer Bros sell the engine sump ones but the gearbox plug is even larger. Do you reckon a Dowty (spelling?) seal would be OK instead?

Dowty's are pretty good, dont your local autofactors sell copper washers?

No one seems to sell any large enough and most just sell the plain washers not the crush ones - even tried Halfrauds out of desperation.

Porsche use crush washers (aliminium) they are a common item as they are used on both the oil tank and the sump when changing the oil.
I don't have one with me at present to measure the hole.

I don't think it would be a disaster to reverse an old crush washer (once) and just check it for "weaping" for the first few days.

I got mine from Rimmers. One is folded annealed copper one, and the other is a fibre washer - I think the fibre one is for the top. I haven't tried fitting them yet, as Halfrauds are out of SMS-X at the moment. Also you can try Think Auto they sold the crush washers in M8 and M10 I used on me 280i

Surly you can reuse a crush washer several times so long as you haven't flattened it? A bit like a compression pipe fitting you only need to do it up just enough to stop leaking then each re-use requires a gnats tadger extra torque to reseal. If you've got Godzilla fingers then you'll flatten it in one go and you'll have to use a new washer every time.

Local hydraulic hose company will sell them. If it's a copper washer, then put it in the oven while you're cooking dinner, leave it to cool and as long as you hadn't totally mullered it, it should be good as new.

I will have another check on Rimmers, I only saw the fibre ones, thanks. I have used the SMX-S in the 350, my local motor factors sell Valvoline oils so I am trying out their fully synthetic gearoil in the 400.

I did reuse it this time but there is a limit hence the question, it is the first change I have done on this car so I do not know how old the washer is.

Can you remember what size? I erm forgot to measure it in the rush to get the car ready for Brands last month.
I like the idea of annealing the washer before reuse thanks, I suppose I am just used to treating them as replacement items.

Try Pirtek, they are a nationwide chain of hydraulic pipe and fittings specialist.

you plank, sorry I can't remember, try measuring the plug across the flats, the washer O.D. is normally about the same size as the nut. The washers are normally a standard size so should be easy to sort out a couple to cover the bases.

Okay, I'm very sad but the calipers and the washers were by my 'puter .

FRC7064A "H/D WASHER-GBOX. DR/PLUG" measures ID 24.55, OD 31.75 , thick = 2.90
WF513 "Fibre Washer" measures ID 16.20 , OD 26.10, thick = 1.65

I doubt if you could anneal copper in a house oven, unless you left it in for a few days. We had to make ours glow orange in the lab, i seem to recall. Still - I never tried it so it may work. I recall you recrystalise certain types of aircraft aluminium for about the same time and temperature as good sized chicken, but that probably aint much help...

Also, the copper washers you get from hardware stores are too hard and don't work on fuel lines at 5 bar - I know this 'cos fuel in yer eye stings a bit.

What size is it?

You should be able to pick them up off the shelf from any good hydraulic stockist. There'll be a Pirtek branch somewhere near you or just grab the yellow pages.

If you really are having problems, drop me an email through here with the size and I'll give our supplier a ring tomorrow.

ETA: beat me to the sizing

I could not find the frc7064 on Rimmers but did find it on David Vincent for 14p. They also sell the sump washers, 216961, for 25p which seems cheap as they are £1.53 on Rimmers. They may or may not be the right ones but as it is only a fiver for ten of each...

Thanks for the help guys.

Update on this

The washers have arrived and they are the right ones. The gearbox ones are genuine Land Rover and the sump ones are Britpart. The washers are less than 30p & 17p with the vat so no excuse to reuse them really.

Thanks for the help and particularly to Jim for the part number.
