Download from the link below. This is the 3V45 JVC equivalent but it will suffice I believe for the deck timing.

Thank you very much John.

I'll have a good read of it this week just to see what I'm letting myself in for.

Cheers
Richard.

Default Re: FERGUSON 3V42 vcr fault.

Hi all.

Just a quick update.

I've managed to source a brand new loading motor gear assembly for this vcr, but I'd like to ask some advice on replacing the whole unit please.

Does it get removed in one whole unit? I know I have to disconnect two levers on the top side (I think pinch roller arm and another lever arm).

When fitting the new unit do the tape loading arms need to be in the fully tape loaded position and tension arm in fully loaded position also?
I don't want to break anything.

Any advice will be greatly appreciated.

Thanks again
Richard.

Hi Richard.

Mechanical parts should always be replaced with the mechanism in the fully home (stop, tape ejected) position.

Hi Fivos.

Thank you for that info. As soon as the part arrives I shall be very careful and methodical in replacing it. I'll take lots of photos too before I start the repair.

Many thanks again.
Richard.

Hi Richard, as Fivos correctly states the deck is normally in the stop or eject position. There are various holes or marks on the chassis and gears to aid you in obtaining the correct timing. I've attached some pictures from the manual showing you what to look for.

You need to pay careful attention to the pinch roller actuator which fits into a groove on the replacement worm gear, don't forget to lubricate the groove also.

If you are in any doubt post some pictures of your deck and I will try to identify the timing marks.

John.

Hi John.

Thank you so much for the info and diagrams. I'm a little bit apprehensive about doing this repair myself, but I'll be extra careful whilst I'm doing it. The replacement is coming from Australia so I guess it'll be a few weeks before it arrives.
I'm going to take loads of photos before I start so I can refer back to them if I'm unsure of anything.

Thanks for the offer of help in identifying the timing marks in case I get stuck. I just hope it goes smoothly

I'll update when the part arrives.

Thanks again.

Richard.

Ps,
Should I do the repair with the deck chassis in situ or remove the deck chassis completely from the unit?

Thanks again

Richard.

It will be much easier to disconnect the cables and completely remove the deck. To make sure you don't refit any plugs the wrong way round use a felt tip pen to mark the plug and socket. Pay attention also to the routing of the cables.

When completed if the timing is correct you will be able poke a cocktail stick for example from the top to the underside of the deck through holes A and C.

Do not apply power unless you can wind the deck by hand from stop to play mode without any signs of stiffness. If you get the pinch actuator correct the roller won't contact the capstan shaft until the guides reach the V blocks.

Brilliant, thank you, John very much for your help in assisting me with this. It's the first time I'll be working on one of these vcrs, so any advice is welcome indeed.

Thanks again
Richard.

Just take your time and you should be ok. I'm afraid I can't help with disassembly of the loading block as I said in an earlier post, back in the day it was supplied to us as a complete item.

It would be nice also to have the correct manual to carry out some testing of the optical mode sensor unit. I'll keep searching but if anyone can help the JVC version of this model is the HR-D455 and the Thorn rental equivalent, 8945.

I've ordered the whole assembly, plus 2 warm wheel gears to put into my spares cupboard just in case.

JVC number: PUS36689V.

It was the last in stock so I'm quite fortunate.

I've found a picture online of it.

Thanks again John

Richard.

Last update on this.

It's now finally fixed and working perfectly.

I fitted a brand new loading motor assembly which I sourced from Australia.

After lots of faffing about I discovered that the arm which fits into the bottom of the cam gear on the motor assembly had somehow moved causing the tension arm not to retract on unlace, which is probably what caused the broken teeth on the original cam gear.

Thanks to everyone who replied with suggestions and in particular jayceebee for helping me diagnose the tension arm problem as ive never worked on one of these models before.

Thanks again all

Richard.

Well done Richard, not the easiest machine to work on so that's a fantastic result.

Thank you both!!

The vcr is in outstanding condition and apparently it was hardly used, so I think with occasional use, it will last for another 30 years. Haha.

Can this be closed now please?

Cheers
Richard.
