Hayter 48 roller drive prob

[Mr K]

Hi folks, just wondering if anyone has had experience of a faulty drive system on an older style, (no OPC), Hayter Harrier 48. Mine has been moderately reliable until the other day when it started but refused to drive the rear roller. I've tried tensioning the cable more, checked the rubber drive belt and all looks good. The roller will simply not move clockwise nor anti clockwise. Having read about ratchet and pawl mechanisms I'm wondering whether the roller has locked up by inadvertently dragging the mower backwards and messing up the teeth within.

If anyone has had similar trouble with the drive on this type of mower I'd be glad for advice on how to repair:001_smile:

Welome to the forum MrK

The old, pre OPC, 48 had a solid rear roller rather than a split one, so no ratchets.

 

It sounds like yours is locked up, and that can only be due to the chain drive having come adrift within the chain case. The roller assembly will have to come out of the machine to remove the chain case for inspection/repair.

Thank you Raffle for your knowledge. I shall take off the roller assembly and remove the chain case, then see what needs to be done from there. Hopefully the chain isn't damaged and can merely be put back in place, otherwise I guess a hunt on ebay for parts.

When working the mower gives an excellent cut, so it'll be worth repairing. Meanwhile I have a push along smaller mower that will keep the grass trim as I get the old beast back to good health. Thanks again

Hey, things went smoother than expected...I removed the spring that holds the cradle up, disconnected the cable, prized off the drive belt, and presto, without having to go any further dismantling I managed to rock the roller to and fro a few times until the chain jiggled itself back into place. Put everything back together, started her up and for a while it pulled like a steam train even through the long wet grass. Sadly the carb must have suffered being left uncovered over a wet spell. When it stalled in the long grass i couldn't restart it, even with a sniff of brake cleaner. Then the heavens opened so I called it a day and retired indoors.

I guess it's carb strip down and clean up next. Did so last year, and had meant to install an inline fuel filter, but never did. Maybe I shall this time round
