Helicoil

Ek het die ding gegoogle. Dit wil vir my voorkom dat party ouens by die goed sweer and ander dit vermy.

Lyk soos twee opsies:

1) Tap 'n nuwe skroefdraad en gebruik 'n insert waarin die sparkplug draai (ek hou nie van die een nie want die insert is nie dieselfde metaal as die head nie. Die insert kan dalk anders reageer as die head wanneer dit warm word)

2) Helicoil.

Ek het gisteraand weer na die plug gekyk en dit lyk of die plug heeltemal indraai (draad nie skeef nie), maar wil ook nie lock nie. Dus draai hy tot hy vas is en dan 'n halwe draai later is hy weer los. Sal loctite nie werk nie? Ek dink nie die plug sal uitspring nie, hy wil net nie vasdraai nie (of net tot 'n sekere punt toe)

Helicoil sal die beste opsie wees. Maak net seker jy het 'n ekstra een vir wanneer jy hom diens - die helicoil kom partymaal uit saam met die plug.

Your option 1) is basically a Helicoil.

You can Helicoil it.
You can buy a new head.
You can find a guy to weld the hole closed & re-tap it.
You can use loctite - but your next service will be fun.

New head is about 4k. I have to go for the helicoil if I value my marriage.

Thanks Manny.

If you can get one up there rather use a TIMESERT - from Wurth

Heli Coil in the plug hole is doomed to failure - the wire becomes a glow plug.

unfortunately a full kit is expensive, but if you make a habit of stripping plug threads it might come in handy...

an engineering shop should be able to do it for you....

Thanks Apoc.

I am taking it in on Monday to get a quote.

Frame was painted by brush - hammerite.

Alu panels sprayed with two coats of etch primer, colour (land cruiser brown ) and clear coat each time.

The dash I did with a alu spray - glu devil I think (same MO as the panels).

Got the stripped sparkplug hole sorted, but now I have a new issue (I hate old cars...)

Drove it yesterday for about 5km. Everything worked well, except the gearbox

When I accelerate hard from a stationary position, the buggy starts to accelerate and then followed by a shudder and it jumps out of first gear. If I accelerate normally from a stationary position, it drives well and keeps the gear.

The second issue, the moment I get up to 30kph (in first) and shift to second, it feels like there is a dull spot as if I have shifted into 4th and not second. If I get up to a high enough rpm, it engages second gear well. When I get up to 3rd gear and downshift to second, the buggy has the same flat spot and shudders as if it wants to stall.

Any ideas?

For the Clutch shudder look on the top side of the chassis in the back where the Gear coupler is situated
The clutch cable runs through a steel tube there that is tack welded to the Chassis
If the welding comes loose this causes bad clutch shudder


For the Flat spot on Acceleration make sure the Spray jet is adjusted correctly
With carb in hand give the throttle lever a jerk and the fuel must spray out the bottom of the Carb
It must not first spray against the Throttle body or side of carb

The spray jet is the small copper tube on top of carb.

Hope the info helps...
