Colin Lindsay Posted May 17, 2022 Report Share Posted May 17, 2022 Just on the subject of O/D (J-type) if I wanted to put an inline (probably blade type) fuse into the system, what would the experts recommend? Link to comment Share on other sites More sharing options...

That depends a bit on your wiring. Are you on a column stalk or a gearknob switch? The latter has a much higher risk of shorts from supply to ground, due to the live feed going up the gearstick. I think the J-type solenoid draws about 3A max, so a 5A fuse is plenty if that's all it protects. The standard wiring supplies it from the green wires, but if you're putting a dedicated fuse in (and doing so in a sensible location) then it may be sensible to feed that fuse off the white. However, if you're using the usual gearknob switch loom then it's actually shared with the reversing lights. Link to comment Share on other sites More sharing options...

It's the column switch on a J-type, powered from the ignition (white) circuit but I rewired the entire system with new cabling and am slightly worried about the bits that are exposed to the underside of the car, plus where the cable exits between gearbox tunnel and bulkhead metal. Well insulated but still vulnerable. The Herald has no fuses so I'd like one in that circuit and as I've an inline blade fuse holder in the drawer I was wondering about the best size.

Pete Lewis Posted May 17, 2022 Report Share Posted May 17, 2022 with any OD misbehaving its always worth a drive and hold the gearstick to the left and the right to see if a bit of a wiggle shows the inhibitor switch needs a bit of adjustment pete Link to comment Share on other sites More sharing options...
Steve P Posted May 17, 2022 Report Share Posted May 17, 2022 On my Vitesse with saloon box and o/d (gearstick switch), i have a 5 amp inline fuse on top of the box tie wrapped to the clutch pipe, been ok for 10 years so far.But i do keep a couple of spare fuses in the glove box.

AlanT Posted May 17, 2022 Author Report Share Posted May 17, 2022 Right. Parts acquired. But questions…realised I didn’t take it off when the engine and box were out, just made sure it ‘clicked’ the upshot being it’s a bit stuck after 40 years. Q1: is it just the single big nut to undo? Or does the bolt underneath (also in the pic) need to come out as well? Q2: which way does the big nut release? Up or down from this position? Thanks Link to comment Share on other sites More sharing options...

NonMember Posted May 17, 2022 Report Share Posted May 17, 2022 Pete will correct me if I'm wrong but I believe it's just the big nut and your ratchet goes down from there. Link to comment Share on other sites More sharing options...

Pete Lewis Posted May 17, 2022 Report Share Posted May 17, 2022 its not supposed to be gorilla tight yes anti clock undoes normal threads with dowty sealing washer your nut looks thick enough to take a normal spanner ??? i just use an old 1" ground thinner Pete 1 Link to comment Share on other sites More sharing options...

Hi Alan, I have a similar problem with my J type and was going to replace the O rings in solenoid as well buy the special thin 1" spanner, however not sure now if it bends that easy? Also how do you use it, with that square hole, or is it designed to just "thump it with a hammer" Regards, Colin. Link to comment Share on other sites More sharing options...

There is a slot for a socket wrench to go into. I’d grind down a spanner if I were you! Link to comment Share on other sites More sharing options...

I have asked on a reply to a later post what the maximum thinness needs to be to grind down, any idea? Colin. Link to comment Share on other sites More sharing options...
Mjit Posted May 18, 2022 Report Share Posted May 18, 2022 I've got one of those and had multiple solenoids off and on but never known/needed to know what the square hole was for. They have always been "hand tight with the little spanner" and worked/not leaked like that. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 18, 2022 Report Share Posted May 18, 2022 well sods law just been out ot measure mine and of the many its not there i would say around 5-6 mm thick i would have thought iains wonky one would undo the square hole is to use a rachet not a mallet !! as i said its dodgy to use grips on the body as you can shear the small roll pins holding the case on unfortunate its been done up by King kong Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted May 18, 2022 Report Share Posted May 18, 2022 This is mine, an old 1" spanner ground down at each outer edge. I didn't really need to adjust the thickness of it, but did anyway, it's about 5mm thick now and the two 'prongs' are down to around 5 - 6 mm as well.

Thanks Colin, gives me a better idea on what is required ie 5 mm maximum thickness should suffice. However, what's the reason to reduce the outside edges? Dont suppose you know the dimensions/spacings for the pins required to remove the internal filter inside the overdrive sump filter plate, as it seems logical to clean this as well as refurbish the solenoid?

You need to grind the edges back as it won't fit into the gap between chassis / bodywork and gearbox otherwise. I experimented when grinding that one and that's the profile that allowed it to fit, both into the space around the nut, and the surrounding metal. The holes are 3/16", no idea of the spacing as I used an old set of pliers ground down to fit. Link to comment Share on other sites More sharing options...
