4bd1 n/a fan belt woes.

[SGT.JOE]

G'day all, 1982 N/A 4bd1 Stage One. I have checked the parts list on here but the fan belt is not listed. the old belt is part number Mitsuboshi 413671-6480 (the 4 may be a 9 is hard to tell), Now I live in Tassie, land of 'oh no we don't stock that mate' so have been all over looking for one of these with no luck.
Is there another brand/part number that will fit?
I need help here as the old one is starting to show cracks! It would be nice to have a spare in my kit as well. the belt just goes around the main pully, the water pump and the Alternator.

much thanks for any help my freinds ;)

Belts are generic and sized according to the width and circumference.

So you can measure yours and go to any auto or bearing shop.

Edit: BX44 imperial size = 17A1120 metric size (17 mm wide and 1120 mm circumference (44" x 25.4))

I'm not sure if yours is the same but I just fitted a BX44 fan belt to the 110

17mm wide - get your belt supplier to look up metric equivalent to 44" if he doesn't have 44"

I think it will be 17 X 1120

BUT... maybe the Stage One had different alternator or main pulleys ???

That sounds about right...

If measuring, the length is measured inside rather than outside.
You can subtract the depth X pi if you've measured the outside.

I've got a standard 1982 ISUZU (with none of this air conditioning and power steering rubbish) and it's running an off-the-shelf 15A1160.

And we have a winner, Captain Slow :D, that would be the one (forgot to say in the first post that it has no AC or PS, My bad) I will take that number with me tomorrow and see what I can dig up. and a big thank you also to you other blokes as well, gotta love this forum ;)

... even if it had AC & PS - they do not operate off the main fan belt

(PS is engine driven, AC has additional belts (as used for 24V gen in FFRs))

I have never owned one with PS or AC so would not know, so is safer for me to go with the one that has the exact same set up as mine. you will note his part number is not the same as all the other replies so I think that speaks on it's own.

Manufactures of Vee belts use their own part numbers, even though they are interchangeable with belts from another manufacturer.

Usually the first part of the number can be decoded into the section size, such as 'A' or 'B' section, or width in mm. If you check the width of your existing belt, or pulley, it is easy to determine if it is an 'A' or 'B' section ('B' is larger than 'A'). There are many other section sizes, but I would wager 'A' or 'B' (my 4BD1T from an Isuzu truck uses a 'B' section fan belt.

Usually the second part of the number can be decoded into the circumferential length of the belt in either inches, cm, or mm. The adjustment for setting the belt tension will accommodate minor differences in length. If you measure the length of your existing belt you then have all of the information you need.

Someone gave an Isuzu part number, there may have also been a Land Rover part number given in one post, the other part numbers seem to be those of the belt manufacturer. The different number system doesn't necessarily mean they aren't interchangeable.

I would never buy from either Isuzu or Land Rover, given their mark up, but from someone who sells transmission equipment, such as many bearing sales places. Good brands are Gates and Diamond, but there are plenty of others.

Fan belt 15A1160 was the correct answer, fitted just fine:), for those who want to know;)
