Replacement Camshaft Pulley

Hi all, I'm getting a replacement pulley machined up from solid billet of aluminium alloy. The engineering firm making this specialises in belt drives and makes all the stuff for the motorsport firms etc. So hopefully no more failures.

Anyone else interested in this?

Regards
G

Solid Billet Aluminium Pulley

Photos show aluminium cambelt pulley versus plastic original rubbish.

Manufacturer was Alan Young Engineering in Broadford, Auldgirth, Dumfriessshire Scotland Timing Belt Pulleys - Specialist Timing Belt Pulley Manufacturer


Really nice finish to pulleys.
They will have the CAD/CAM files in place so will be cheaper for subsequent purchasers.

No more pulley failures!

What age is your Honda 20? Is the pulley the same on all the 20s?
Cheers

Hi Danork, my Honda 20BF was brand new in 2008. Used for about 50 hours.

Plastic cam pulleys with metal hubs are a bit of a rubbish idea!

Regards

Thanks for that.
I am considering changing my outboard. If I keep it, at the end of the season, I will give them a call and get one made up.
thanks

Hi all, contact details for Alan Young Engineering in Dumfries Scotland is revised to alanyoungeng@btconnect.com tel 01387 740404.

They have been shipping the all metal camshaft pulleys for the Honda BF20D outboard, to destinations as far abroad as Canada and Finland.

Plus I had a query from an Australian BF20 owner.

regards
G

My CAM pulley just failed for the second time. First time at 40 hours and now at 60 hours. Exactly the same problem.

Thank you I have the same problem. I will order 2 aluminium pulleys. No more bent valves for me.
I have two BF20 motors on a 40' Cat. One just stopped working after about 25hrs.
I removed the plugs and could feel no compression.
After removing the cam belt cover I found the belt had fallen off and the cam pulley was loose on the shaft.
Turned the cam to close the valves and re checked compression with finger.
Still no compression on one cylinder.
Removed head to find bent exhaust valve.
Replaced valve and pulley and now OK.
Even though it was only 1 year old and still under warranty I could not wait for the repair so I had to fixed it myself. I got the parts under warranty.
