Source for idler pulleys?

Recommended Posts

Sometimes you get lucky and find a direct relacement and it lasts. What's wrong with this is if someone replaced the pulley before you and now it's incorrect for the application. I have found that some/most manufacturers select odd sized belts/pulleys and such for some applications so the local supply houses cant match up stuff. This leads to lost performance and breakdowns. If a part has been copied from the orriginal manufacturers specs then you would be OK. But you'll find they take several sets of specs and average them together and produce a part that might work for awhile but it'll never give you the results of factory replacement parts.I'd go with Al's recomendation and get a genuine replacement part. At least for the first one and try then to find a match. That way you know you at least had what it called for. You'll also get to see actual comparison between OEM parts and a substitute.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
