Bolt behind the alternator.

[Bolanrex]

Hi. The bolt behind the alternator in our Izuzu 42 engine has snapped. The thing that tightens up the fan belt.

Anyone know where we can get one. Uxbridge marina can't send for one till Tuesday. We'll be dead before then.

Thank you

Take the old one to Orbital Fasteners in Ricky.  They will have a suitable substitute.

Any half decent engineers suppliers should be able to find something that will do the job

Just remove the old snapped bolt from the alternator and with an ordinary  bolt and big washer passed through the back of the slot in the bracket and  screw into the alternator and adjust the belt in the ordinary way with a lever. If you have'nt got a bolt of the right diameter and thread just use the next size smaller diameter instead which should pass throgh the threaded hole in the alternator and put a nut on it instead, until you get the correct bolt.  Retain that thick spacer washer between alternator and bracket.

It's a standard 8x1.5mm thread, common as clay.

It's the bit that goes through the arch which has the funny head on

The drawbolt?

The threaded draw bolt is the long one dangling on te end of the adjusting bracket. It screws in and out of the shiny knob bit on its end which moves the alternator to adjust the belt. Both those parts should be ok. Its the one screwed into the alternator thats bust and left a bit of  that shiny knob bit. in it. You need to remove the slotted adjusting bracket to see to it. One bolt low down holding it to the engine.

 ''A'' is the shiny knob bit with the broken off bit of the end of the bolt that it swivels on which is the one still in the alternator.

Thats correct, it has.

What you need is a short length of threaded bar with a washer welded on the end a bit like a spoon. Put a bolt through the washer, slotted hole and into the alternator with the end of the bar through the drawbolt hole in the adjuster. Run a nut down it to tension the belt then nip up the bolt that goes through the washer.

There is a company called Gilbert Lawrence on the industrial estate in Wallingford road, Uxbridge.  They will have something suitable and won't be expensive, they also are happy to sell any amount from one upwards. Take the old one with you.

Another option is an old school auto electrician/supplier, you can find them off the roundabout where Sainsburys is, just turn left instead of right for Sainsburys and you'll find them on the left in a small industrial estate. They will also repair alternators, battery chargers, etc.

Just for now unthread the bolt going into the altinator so you can get a nut on the end going though the metal bracket with a flat washer  but before nipping the nut up use a bar to leaver the altinator to tighten the belt
