I assume a reference to dowty washers...but none of the J-Type overdrive's I've ever taking the solenoids off of have had dowty washers, just plain copper ones, as listed in the parts book (NKC108).

Pete Lewis Posted May 26, 2022 Report Share Posted May 26, 2022 its an anti rust down grade ha ! so long as it has a sealing washer i would be happy getting on the darn thing in the small chassis cars is the Faf Pete Link to comment Share on other sites More sharing options...

I used one on my last O/D (GT6 with aftermarket J-type) just to be sure, but any kind of copper washer will suffice so long as it does what it's meant to do!

Bit of Blue Hylomar/Stag Wellseal around the washer, lower threads as back up, if you have any. Out of interest, will fibre washers work, or does oil soak though them?

Pete Lewis Posted May 26, 2022 Report Share Posted May 26, 2022 fibre washers do seal well and have some compressibility but not as good as copper if there is a lot of pressure involved a fibre may let go ie you wouldnt use a fibre washer on brake lines and i dodnt know what pressure is contained in the J type solenoid zone , both have their uses but its the use that determines the usage Pete Link to comment Share on other sites More sharing options...

Odd, I can't say I've ever either found traces of it from previous owners or any signs of oil leaks coming from the solenoid connection. I do though have a constant leak from the o/d sump on my Spitfire, from where it's clearly been dropped at some point so no longer perfectly flat surfaces. Lots of surface cleaning and a new gasket with gunk all over both faces has it down to a managable drip rate though, and thankfully the o/d's built in low oil level warning reminds me to top up if I haven't (gets slow/reluctant to engage). One day I'm sure I'll have to take the gearbox off to fix something (and not need the car back on the road ASAP) and will address it properly then - but it's been like it for over 20 years so far...

daverclasper Posted May 27, 2022 Report Share Posted May 27, 2022 Is that a J type Mjit?. I have a J Type and GB started leaking about a year ago, apparent from the drain hole at bottom of bell housing. I think it only leaks when car is running, as when you wipe of the oil from that area the next day, then doesn't leak anymore. The level was checked a year ago and car has done only about 1500 miles. Was surprised when it took about two thirds of a litre to top up. Must be chucking it out a bit when running I guess. No symptoms like you described. How much oil does yours take to top up when you have the warning? Link to comment Share on other sites More sharing options...

If so, it will only leak when the engine is running, as the shaft is above the oil level so it only gets oil there because of the gears spinning.

Mjit Posted May 27, 2022 Report Share Posted May 27, 2022 Been a long time since it got down to the o/d complaining as I just check it/top it up at the start of the year and before/after any longer trips - like the 1,000 mile trip to Le Mans 12 days time, for the 24hrs 😃 Link to comment Share on other sites More sharing options...

Like many old connections or joints, they tend to seal up over time and so don't leak. Once they're disturbed, it's often a different matter...

Pete Lewis Posted May 27, 2022 Report Share Posted May 27, 2022 have to say getting the darn thing off a spifire is a right faf to get any sort of spanner rotation needs the box lifting just two bolts in the tail hsg. but one covered by the angle drive thats another faf getting it out the way agree the spanner from JP is far too clumsy to fit and needed its ears reduced to get any sort of fit its been a nightmare from the start with H frame bolts that dont, to pauls trolley jack that doesnt and too far from home to keep getting tools but its off waits me testing and re 0 ring the blighter too many parts had been fitted by a gorilla Pete Link to comment Share on other sites More sharing options...
AlanT Posted May 28, 2022 Author Report Share Posted May 28, 2022 Hurrah! We have a turn offable overdrive! At least all seems well on a short test drive…boiling hot isn’t it if you drive one of these with no transmission tunnel in! Just this lot to deal with… Thanks everyone.

Josef Posted May 30, 2022 Report Share Posted May 30, 2022 And being able to see the driveshaft spinning away there inches from your legs is always a bit unnerving when doing a tunnel off test run! Link to comment Share on other sites More sharing options...

Pete Lewis Posted June 7, 2022 Report Share Posted June 7, 2022 just to follow up my local J type the solenoid 0 rings were fine but the innards had a lot of crud to wash out now it rattles well but still disengaging at times not the random in out so a quick check of the inhibitor switch by holding the gear lever towards the driver test shows it needs some adjustment a quick removal and adding a bit of set in the remote bracket and all is well so two problems , solved Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted June 7, 2022 Report Share Posted June 7, 2022 Dave getting the solenoid of on a spitty with a J type is a right faf dropping the tail mount off is easy just the 2 bolts so you lift the gearbox re aligning to refit is another cause to be grumpy luckily i was advising not groveling Pete Link to comment Share on other sites More sharing options...
