Hayter 56 vintage

[Kevin18]

Hi. I wonder if someone can help me identfy which drive chain I need for my old Hayter 56. It is an old model with the drive coming from the side to a pully and then a belt to the real roller. It lost drive and when I investgated the drive chain appears so loose that it rides up the edge of the small cog and jams stopping the drive instantly. In doing so it has caused a couple of burrs on the teeth of that cog. My problem is identfying which chain I need. The label has long gone from the mower. All the chains advertised on line seem to have 40 links whereas mine only has 15. It is 7.5 in long when stretched as far as possible and the links are 3/8th wide. The only ID on the actual chain is the brand KMC. I am hopeful to be able to file the burrs off the cogs but possibly replace those also. Thanks in anticipation

Are you sure it isn't a 48, see images.

Thanks for your reply Derek. I must admit you have me thinking now. Unfortunately the problem happened in France & I have only brought the roller home. I wonder if the rollers are different in width & as such would confirm the model. The chain in images does appear to match mine. I didn’t think I have ever had a 48 but maybe I have!

Is it the same size as bicycle chain, whilst not stereotyping the French a local shop could make one up if you can't find the old part.

Hi Gareth. No I am a keen cyclist & I can confirm the chain is a far heavier construction than I have ever seen on a bike. KMC do make bike chains however.

The chain side plates often have a number stamped on them and this can identify the chain type.

If you can identify the chain, purchase a meter length and a link so you can make your own, usually by grinding the rivet off and then driving it out with a punch. The link can then be fitted with the closed end facing the rotation direction.

Just done a Rover mower which was a 35 ANSI chain...cost around £12 for the link and enough chain for two chains.

If you can't identify the chain type then it comes down to roller size, roller pitch (measurement between roller centres) and the width of the chain. Unfortunately, many chains are close in sizing.

Thanks Spudulike, Gareth. No ID on the links other than KMC. I think my next move is to try to confirm that my machine is a 56 or 48. I find it difficult to belive that I have always thought this was a 56 when maybe it isnt!! When I bought it it was as a 56. I which had had the whole mower here now as I cut measure the blade.  I have measured the roller and it is 18inches wide. Does anyone know if that confirms one or the other? Thanks

[GarethM]

What's 18" in that then there modern numbers 😉

Well Mr Google suggests 45.72 which sound an awful lot, best stick to something I understand!
