400F fork oil capacity question.

[Laverda Dave]

Sorry Nigel, the thread was hijacked .
Back onto the subject......I had 10w grade in the Norton forks but was told to use 20w grade so I drained the old oil out and replaced it, I couldn't tell the difference! Maybe it was just old technology used in the construction of the dampers etc?

We can cope with thread drift on here, unlike some forum it's part and parcel of our humour in day to day operations with old vehicles    all good.

Yes to some of the older dampers having very little in the way of accurate valuing or control in hydraulic terms to be very responsive.  Many didn't have much compression or none at all, just some on rebound to stop it being really bouncy, that's as I understand it. Some logic to that, but not to what we expect nowadays.

Anyone familiar with old Morris (BMC etc) type lever arm dampers will know that they got there much before Suzuki made their "killer" V-twin rotary damper, reputation destroying chassis  you could use beef dripping in those Morris type    (that's a joke delta    ) and find improvement by leaving the minced beef in there too

That takes me back doing a lever arm conversion on an old MG Sal0on I had - complete with suicide front doors, semaphore indicators & running boards.

Some of that era is coming back into use Ted.

VW ID3 rear brakes, for example, are drums....closely resembling "minifins" if you used them.

Quite large diameter and so fairly high braking torque, they dont in reality need much heat management with regen braking strategy  on them. Also advantageous is that they dont go rusty from lack of use, especially in Scandinavian climatic road conditions where rusting disc etc appear to be a vulnerability within a modestly driven vehicle.

Good grief, you've all just hit a memory cell!!  I worked for Brown Bros. motor factors until 1985, and I can still remember we kept a reasonable stock of BMC front dampers, somehow the part no. 8181 comes to mind.  I clearly recollect Austin Cambridges and other badged equivalents coming down the road impersonating a yo-yo when the dampers were shot. Plus of course they could be fixed by Kerbside Motors Inc.  Gearboxes played havoc with your ribcage though!!  Happy Days eh?

1871678 were AC Delco points Vauxhall part number F type. Victor's iirc

I worked in the Stores Department at a  Vauxhall Dealers as a student.

It is truly sad that you remember numbers like that Ted

Myself, I can’t ever forget the telephone number for Radio Luxembourg.

They must have trotted it out every couple of minutes.

Was that anything to do with K E Y N S H A M ?

Update:- Google search mentions Horace Batchelor the pools Infra Draw method!

No idea Ted but googling it just now shows this:

Back on track subject wise I put fresh Castrol 10W fork oil in the 400 today - left side cap went back on easily, right side I had to unbolt the brake master cylinder as there was not enough room for me to press down the cap and rotate it with the cylinder in position. Probably a combination of having long fingers with weak strength due to advancing decrepitness.

Top Tip

Obvious to the experienced - if changing oil in situ do one side at a time - otherwise the front wheel dips as the springs are pushed out so fitting the caps is more difficult. I actually used a large rubber cork & jammed it between the right fork top & the master cylinder to hold the suspension down as I fitted the left cap.

I used to loosen the bars until I could rotate them out of the way, easier to push down on the top nut that was as well.
