  1. Ozzie Saladin

    Sorry fadedsun, just spotted your post. No recent progress on the Saladin. I've been sadly distracted - one of the joys of MVs and life! The Saladin is on its 6 wheels and parked nose in to side of shed. Engine is off getting restored. Got a NOS Saracen hydraulic pump that has a single pulley and I need to change that to the double pulley for the Saladin, or change the whole pulley set up to the Saracen type (but that would waste the Saladin PTO). Think it's doable but haven't quite got around to it yet. Soon... SHMBO then decreed I "tidy up the shed, or else.." (whatever that means, ) so bought an old forklift and pallet racks and put the stuff that was annoying her up so high she'll never have to worry about it again. The floor looked good for a few weeks. Got sidetracked with a Ferret that became incontinent of water, oil and petrol. All sorted now (posted about that). Drove the Saracen to a Xmas party - nearly wiped out the missus on a steep hill and it boiled, which is the subject of yet another posting. Feeling confident that it will soon(ish) be back on the road. Along the way a HMMWV fell into my lap - well, you never know when it'll come in handy... At least it is driving nicely with no issues, although you do need to keep well to the left! Hmmm, what else.. found the tarp cover for an old landrover series one 80" (thought it was the cover for the barbecue for a year or so) and have just got that back after getting its beading re-stitched. And a new grand daughter couple of weeks ago - worth much more than anything else! Hoping I'll be back on the Saladin in the next month or two, so hopefully some more-interesting posts before too much longer. Cheers James
  2. Saracen coolant pump

    Thanks guys I've sent the radiator off for checking and have ordered a new pump and thermostat, so we'll see how it goes. Will also flush the block.
  3. Saracen coolant pump

    Still a dilemma! Got the pump off and took the back off it but really can't see anything wrong. The impeller is in place and it spins without making any noise. No broken bits to see. (Also worked out how the adjustable pulleys work, once the belts were off - they are threaded together independently of the threads on the shaft, which are used just to line up the belts and pulleys). Now I'm really stuck! I'll replace the back on the pump and see if I can test it off the engine by spinning it e.g. with an electric drill. If it pumps then maybe the internal waterways are blocked, however water pumped through with the electric pump and it was a NOS engine so this seems unlikely. Back to thinking about an electric pump. I could replace the mechanical one but can't see how this will make any difference.. Sage advice please!

    That has to be the weirdest way to adjust fan belts! The Saladin has a jockey pulley and it's obvious how that works, however it's not clear how spinning the Saracen pulleys (sheaves - thanks Lowfat) to the rear along their threads loosens the belts - I can only assume that the fan axles are not parallel? Anyway, it does and I've got the belts off ( I hear your applause and a few groans). My next dumb question: how do you remove the fan assembly? There are two bolts at either side and at the bottom there seem to be just a couple of pins, so it should just lift off. However there is stuff (mainly electrical connectors) in the way. I guess I have to remove those (not in the EMERs) but wonder if the bolts can be pulled down so the assembly could then swivel out rather than lifting it up. The bolts might be fused to the rubber mounts so don't want to apply brute force needlessly. Forecast 33C tomorrow and 39C Sunday so will probably give the shed a miss for a couple of days, but looking forward to getting the pump out and seeing what's going on! Cheers James
  5. Saracen coolant pump

    Hi Richard I just thought you were brief and to the point! I take your point that the pump might be blocking something and will take it out, although I might need a bit of hand-holding with this. I've sourced a NOS pump. The front armour and radiator are off. Do I need to remove the fan assembly or can the pump be removed without doing this? Will have a look tomorrow to see where (what) the belt adjusting pulleys are. No idea what the sheaves are but might be obvious when I look. Sorry but this process might involve more cries for help. Cheers James
  6. Saracen coolant pump

    OK.. Removed the radiator and it needs a bit of a service but not too bad. Connected the electric pump (which is leaking) to the bottom hose and got 5 litres out the top pipe in 30sec, which is probably correct for that pump, though a bit light on for the engine, probably. Then ran the engine with the same set up for a minute but nothing out the top, so it is the water pump that's shot. Can't find the flow rate expected with the mechanical pump and would be interested if anyone knows. What to do now? If I remove the water pump it will be a saga and I don't know if or how it could be repaired. Seems logical to fit a (bigger) electric pump to the bottom hose, if it can be wedged in there, but has anyone done that? Davis Craig recommends a 150 l/min pump +/- a digital controller to work the pump as needed for large engines, and this does look like the simplest solution...

  9. Saracen coolant pump

    Connected the outlet pipe from the thermostat housing (thermostat out) to a bucket, ran engine for 5 minutes and got 8 litres (2 gallons) of hot water (while running cold tap water with a hose into the filler hole). Running at only slightly fast idle. So about 0.4 gpm. Not sure what it should be but suspect at least 10 times that amount. Air flowed out to the front (RF) and seemed reasonable. The engine bay is very clean so don't think the radiator fins are gummed up. However while it seems most likely to be the water pump I guess poor flow through blocked internal radiator tubes can't be completely excluded. Need to decide whether to replace the mechanical water pump or fit an electric one to the bottom hose (or both?). Either way seems to involve a lot of dismantling (EMERs anyone?). Might try squirting water under pressure to make sure the internal galleries are patent but it was OK with the electric pump before the relay failed. Oil level seemed quite normal. I think my next step should be to double check that water flow through the radiator is OK, and if I undo the drain plug and pour water in the top that should give a rough idea? Otherwise......
  10. Saracen coolant pump

    Hi Richard Been down the coast so nothing done today. It has the metal sheet and rubber cowling and I assume the fans blow out to the front but (hopefully tomorrow) I'll reconnect the output hose and run it into a bucket to see if the pump works and which way the wind blows. Will post again with those details. It seems that there are lots of possible causes so watch this space! Cheers James
  11. Saracen coolant pump

    Decided to first see if thermostat was stuck closed, and discovered that it's been removed, so scratch one possibility. Removed the electric pump and will get tubing to see if the mechanical pump works (guess not but it was a NOS motor). Next flush the radiator and check the pressure valve, I guess, and then look for scarier things like head gaskets. Lots to do but think it's worth sorting out for the longer term. My question at this stage is, do I really need the thermostat? Will it cause terrible problems if left out? Thanks, James.
  12. Saracen coolant pump

    Ah well, looks like I've found another project to keep me away from the Saladin! Took the Saracen (RF) for a run and it boiled. The previous owner had similar problems and worked out that the pump wasn't working, so fitted an electric pump between the thermostat and inlet (top) radiator pipe. Had no problems with it but now the electric relay switch has failed (which is why it boiled) and while I can replace that (having temporarily bypassed it) the electric pump is leaking anyway (not the connections, the pump body). So, my first query is, how hard is it to take the mechanical pump off and fix or replace it - would I need to remove radiator to get at it or could it be done in situ? If it doesn't involve a huge amount of work I'd prefer this. Probably the best way to go in any event? Second query is whether it would be reasonable to just replace the electric pump. However while it was working fine, it seems to be in a position where it is sucking water through the thermostat and back into the top radiator pipe rather than pushing it from the bottom radiator pipe into the gallery. So if I went down that path I'd be looking at connecting it to the lower radiator pipe, which might also be a pain. Sorry to be so long-winded. Any advice appreciated! James
  13. Welding Ferrets

    I've experimented with stud welding armour plate (took the driver's hatch down to a welding place) and the "normal" stud welders failed miserably, with the studs easily knocked off. However their 3 phase stud welder did the job admirably. They did give me a sheet with the power needed but I don't know where that info is now. However it was just a matter of trial and error and in the end it was easy with the right device. They didn't have the correct size studs - had metric studs that were slightly thinner than the existing. Another idea suggested was TIG welding a bolt that had its head ground down thinner. Drilling and tapping isn't anything that I'd consider. JB Weld might be OK for hairline cracks that aren't overly structural, and it would be fun to try it for the studs but very much doubt it would be up to the task. Cheers James

    Thanks Malcolm Agree with your thoughts re the plugs and will try your suggestions. James
  15. Ferret Fluid Flywheel Seal

    Not ready to pressure test yet, however wandered down to the local hardware store and found a couple of fittings that connect to my pump inflator after removing the wand. Plan to use gas tape rather than ordinary teflon tape but it's pretty basic, so if it shows a drop in pressure I'll make something a bit more sophisticated, with proper valve, before blaming the FFW. So start with inflator and remove the wand Get your fittings And it should work, but depends on no leakage from the inflator, which might be asking too much - time will tell!
