No problem there Clive, there's nowt wrong with a bit of over engineering

Mazda didn't think so either, when they designed the KL engines...

Or Suzuki for that matter with the GS engines..

gotcha, and i suspect any excess that protrudes i just cut off...i think i have an angle grinder somewhere.

**Postal Dude** · 8-7-08, 13:28

That's right Clive. The tang is only there to drive the helicoil in.

hello again!

right, i got my new helicoils today, and inserted two of them, one for the larger bolt hole, one for the adjuster bracket bolt. Although the new larger bolt doesnt look like it has enough thread on it (or is too long) the adjuster bracket one looks fine, so its off to buy some new bolts again. ONLY one problem now has arisen. After fitting the pump, I found that the lower bracket bolt (the one that was holding it all together originally, wont tighten up!! When i checked it (minus water pump) it did tighten up, so i either have to take it all apart again, and re drill that hole or get a longer 9mm bolt. Only thing is i cant get my drill down into that particular hole, not enough room for the drill and bit (i would need a very short drill bit, probably half the length) any ideas any one?

can i force a larger bolt in or am i asking for trouble? the new bolts i bought are M10, but dont look much bigger, this does start to screw in, but gets a bit tough after a few MM....

also, JOHN, can you remember where this bit connects?

this is the bolt hole that is now the problem...

hope you guys have some ideas, thanks in advance!

Longer bolt maybe... or bring the helicoil further out, if the bolt is long enough..

That plugs into the harness that I lifted and moved to the back... once you bring it back round it will be obvious..

John

**clivjoo** · 8-8-08, 15:57

ahhhhh yes i see, thanks!

as for the bolt, hmmm..i am really unsure about this., i will try and get a longer bolt of the same size tomorrow and see hwo that fits..anything to avoid drilling a new hole (which like i say is probably not going to happen)

just to be clear, its the lower bolt that goes through the water pump, no room for the drill to fit in level, only at an awkward angle...

**Einstein** · 8-8-08, 18:00

If it screwed in before, it probably will be fine with a longer bolt....

Have you made sure you have the right thread pitch? What exactly is the thread on the helicoils e.g. M10x1.75 and do your bolts match this exactly? If you have a different pitch it won't fit. The pitch is the distance from the peak of one thread to the next. A finer pitch has more threads per inch (TPI) than a coarse one.

I agree. If the bolt feels tight after a few mm's it's most likley to be the wrong type of thread even though it's the same diameter. Don't force it.

hi, well, i thought i had the right pitch-the helicoils are 1.5, which is what the new bolts are, the problem is that the new bolt doesnt look to have enough thread to tighten right in, so i need a similar bolt with more thread!! but the main issue is the other hole that has presented itself, with the waterpump on and bracket, the bolt wont tighten up (without all this the bolt does go right in and tighten up!) so i think i either need a longer bolt, or i am going to struggle big time to drill a new hole!

**Postal Dude** · 8-9-08, 5:28

get yourself down to B&Q and buy a length of threaded rod. This is a steel rod that is threaded for it's entire length and is usually sold by the metre. It's not expensive and should be a couple of quid a length. Buy a few M10 nuts too and now you can cut a length of rod off to suit, screw it in the hole then just put a nut on the end.
If you have trouble screwing it in the hole you will need to put two nuts together at the end, lock them together with two spanners then use a spanner on the outer nut to screw the rod in with.

Gerry

**clivjoo** · 8-9-08, 5:40

thanks Gerry, good idea, I will do that. It does look like there is enough thread left inside the block, but right at the back, at the front its just a bit wider than it used ot be due to the movement. will let you know how i get on (of course!)

**Einstein** · 8-9-08, 5:47

Is this rod going to be strong enough.. considering it's for the engine mount..

John

**Postal Dude** · 8-9-08, 6:07

yes easily! The Aluminium is the weak point not the fastener.
