Hi in the process of replacing my ace pipes,I now need to remove viscous fan on my disco td5 so out come my flat dog spanners that my daughter brought me last year never been used till now, tries and put the spanner that holds the pulley only to find holes to bolts don't line up not impressed though these look good tools and we're not cheap you thought they would be suitable for the job. Has anyone else had this issue with said make spanners and how did you get round it? Holding pully bolts whilst undoing the nut.thanks
 
I also have and it works fine. But surely not so easy to align the holes to the bolts. Once it is on i put the other tool to the fan nut which keeps the first one in position. Then i can loose the nut...

I just used an el cheapo pulley holding tool from eBay to do mine. Bit of a git to keep on the bolts but it did it eventually. Think it was about eight quid.

Mind you I did have to give each flat on the bolt a robust tap with a hammer and blunt chisel bit before hand as it was seized lol.
 
Bizarre, my Flatdog set works perfectly. I cannot imagine that they vary the dimensions of their tools; do TD5s come with differently spaced bolts?

Hi I don't know about the spacing of the bolts I know I tried to fit the spanner earlier but will try again in the morning looking at the finish of spanners I would say they are laser cut so could be a different diameter

yes try again. As I have said, for me it was also difficult the first time to put the 3 holed "holding tool" on.
 
Hello lynx45

I bought Flatdog spanners at the beginning of this year and also had the same problem. I measured the distance between centres of the holes and the distance from the outers to the centre was different by about 2mm from the distance between the two outers. I used a round file to elongate the centre hole and all is now well. I did see something on the web recently about the same with a picture drilling out the centre hole. Can't remember the link though.

Cheers.

Thanks PopPops
That's what I thought I struggled to get fan off the outer holes lined up but the centre was out which way did doi file out the centre hole cheers
 
Hello lynx45

If yours is wrong in the same way mine was, you elongate the centre hole towards the handle, away from the other 2 holes. On the web they just drilled a bigger hole, but I didn't have a suitable drill at the time.
I hope this helps.

Cheers.

Thanks another job to look into managed to get fan on without using that spanner just tapped it with hammer on with the 36mm spanner
 
Isn't this just crap that we are reading and posting about a tool that has been sold to do a job and simply doesn't do it? Must admit I made my own tool for my Disco one which was two lengths of flat bar, one short one long, and three nuts and bolts. All you need then is a drill and you can make your own adjustable tool, useful for all sorts of similar jobs, (see various Haynes Manuals). Judging by the appearance of the big nut, other previous mechanics had just hit the flats with a cold chisel until it undid. (I'm the 3rd owner and the previous two would never have lifted a spanner!) I did once see a tool specially made to undo this type of nut. It consisted of a long tough old bar, connected to a very short bit of the same bar with a substantial nut and bolt, tightened not too tight. At the other end of the short bar was a square hole to take the square shaft you would use in a torque wrench or similar. You could then fit any size socket to the shaft, put it over the fan nut or the crankshaft nut or whatever, so that the long bar pointed upwards, to the left of the nut you were going to undo (anticlockwise). You then picked up the proper FBH and whacked the end of the long bar downwards, worked exactly the same as an impact wrench when you cannot get an impact wrench to the nut. Relied on the resistance of the inertia of the thing the nut or bolt is connected to. Come to think of it, saw it on a Land Rover Youtube thing!
