idler pulley rebuild

Postby moneypit » Sat Apr 04, 2015 10:14 am



Ok so I have bad pulleys on Moneypit .Thought I would save a bunch of money and do the DIY rebuild from this sight. I went by the directions cutting the pulleys off from the bracket with a thin cutting wheel on my grinder. The gap between the pulley and the bracket is about .030 my cutter was a tad bit bigger so actually took some stock off the bracket behind the pulley I attempted to clean up the surface . When I bolted up the pulley to the bracket I could already see a problem the pulley no longer sat parallel with the front of the motor. I bolted the pulleys up to the engine put the belts on all marks aligned rolled the engine over by hand and instantly the belts walked themselves off the cam pulley because the pulleys are not parallel with the front of the motor. I took the brackets to a surface grinder with a magnetic table took .020 off the face to true things up. Problem now is under the belt tension the bracket twist thus its not going to work . If I had it to do over I would separate the pulley from the bracket with a vertical band saw . That mite work a bit better . Now I don't trust the tensioners, don't want to grenade my engine when the timing belt or belts come off so I called my local Honda dealer and bought New assembly's with the springs for 85.00 a piece . I probably should have done this from the beginning .I think something as important as timing belts on a wing shouldn't be scrimped on ... Live And Learn...

The reason I am changing the idler pulleys on Moneypit is they are bad with making a whining noise and there was movement in the bearings.

Dad gum it,, All that work too.. :shock: I didn't know you could still buy them, $85.00 each seem to many as alot but to me it seems reasonable if you want good new idlers...

They did pretty good designing these motorcycles back then.. OEM is always good to get if they still sell the part...
