Fan belt (or is it just called an alternator belt)

[Psycloud]

Hi All

 

Trying to build a collection of must have spares and think we should carry a spare belt (the one that goes from the flywheel to the alternator).

 

The engine is a Bukh 36 and currently has a belt that is 1145mm (45") long (outside circumference) by 9mm (3/8"), and has a serated V section (with a flat bottom).

 

Where/what belt should I get as a spare - there are no visible identifying marks on the current one to get an exact replacement.

 

Thanks

 

David

It might be worth taking the belt off now and take it to Partco or somewhere similar and get a couple of spares.

9mm is XPA section, 10mm is SPZ section. To determine size http://www.durabelt.com/beltlengthcalculator.php

I still refer to it as a fan belt

 

keep it simple I rekon even though it also drives the alternator's and water pump.

If it was built in the seventys, surely it'd be a tight's or panty hoes belt.

Specific suggestion:-

 

(when I had to use V-belts) I always bought from Bearing Boys and their own brand (Medway) lasts 'forever' The nearest size for you is:-

You may find it cheaper elsewhere, in which case go for it. Happy to post if that's practical for you.

Does it matter that the Medway ones appear to be solid as opposed to the sawtooth style? I don't mind so long as it works?

 

Thanks.

The idea of the notching is to help the belt grip on small diameter pullys but as the DV36 only has two pullys and un-notched belt will probably do. However the ones T W Marine sell are notched.

I wouldn't dream of using my wife's stockings as mine are perfectly good.

Yes it does - toothed = 'cogged belts are much better for a small increase in price. When I changed the cogged belt lasted for some years until I replaced the engine. The plain variety lasted barely a season.

 

My sincere apologies - I posted the wrong item. Her we go again:-

Medway call them 'cogged' belts

Thank you for this. The link shows 9.7mm - I measured mine at about 9, but it's been on there a few years so I guess it could have started off about 9.7mm The pully will definitely take it.

 

I will order 2 today!
