Roller & Idler Kits are similar. Two seals, two clips, two bronze inner bushings, two steel outer bushings and a shaft. We supply complete kits at a slight discount, or the components parts separately. Parts for HG's, OC3's, OC4's are all the same, except the idler shaft & nuts are larger on the OC4.
Tip: these parts should always be lubricated with oil not grease! The oil is pumped into channels & galleries via a buttonhead fitting or "zerk". If your machine came with grease fittings, I'd suggest changing them out immediately. Many, many times I've seen excessive wear caused by the use of grease.
The one exception to that rule would be JD Cornhead Grease which works fine.
Apart from the long steering levers, all other parts are available as new — threaded hand lever adjusting rod, return and adjusting rod springs, adjusting nut, washers, hand lever stud, hand grips, clevis pins and cotter pins.
Brake bands are available reconditioned with new pads and rivets. Send me your old steel bands for a 'core' discount.
Tip: Brake bands are much easier to change than folks often imagine, and if you are 'heaving' on the levers to steer, you will be absolutely amazed at the light touch needed with a new set fitted.
See my illustrated Brake Changing guide on Facebook.
