Can someone please help me with a belt question? My 85 mitsubishi diesel 4d55 is eating belts both alternator and power steering. Horrible squealing and premature wear as I do not know what size I should have on both pulley's. It has no air, so I was wondering if anyone knows what the exact belts for replacing both are and if you can list them for me. Your help is greatly appreciated!
Sounds like an alignment problem. I would look at that first because it will rip belts to shreds.
Or, one is getting really hard to turn.
I appreciate that but does anyone know the exact size of the belts?
IDK the part number. But it should ride nicely in the groove with out extending out the top of the pulley or going to the bottom. Sorry.
Can anyone tell me the exact size of the two belts that go on the alternator and the power steering on an 85 4D55 Turbo Diesel. I cannot seem to find the right belts by guessing. I am getting squealing and the destruction of belts. I know, change the pulley's but that seems to be an issue as well as it is unclear what fits what from Napa and Rock. Any suggestions would be greatly appreciated!
Thanks.
For shits a giggles I looked at Rock Auto like I would have done if I actually needed belts. Damn if they didn't list a whole gang of them. Sizes too.
I did but it is as vague as some of the other sites unfortunately! Thanks
The belts I have on it that I just replaced are one for alternator and one for power steering. Rock lists AC belts??? I do not have AC and the one belt that I really need right is the Alternator belt and it is too skinny and recesses too far down into the pulley and that is where the squealing is coming from. They also will not stay tight, they loosen up to quickly! No pulley replacements it seems as well. Real problem for me.
I am sorry what does IDK the part number mean?
Thanks

I would suggest buying the alternator belt from Rock Auto. Probably the Continental one. Can I vouch for it? No. But I'm pretty sure that's where I got my last set of belts, and I didn't have the problem you are having.
As to your question about what the size should be, I'm sorry, I don't know.
Thanks Huff, I did see the Continental one on there. I just purchased two from NAPA. One was for the power steering and the other unfortunately was listed as an air conditioner belt, but I figured I would try it. I will get the exact stock numbers on the belt and let you guys know. If figure I will try napa first, and then go even blinder with Rock if these do not work. At this point I have $80.00 bucks in this now. Pathetic, but there does not seem to be any pulley's that I can replace as the pulleys are on the motor and the alternator and the power steering box, so I figure I will go through the belt scenario first, then if I cannot find a match, probe deeper. It is a shame because aside from the squealing, it runs like a top, perfect, so we will see. Thank you all for your input. One other thing: The belts continue to get loose and my mechanic does know his business, he says they have tightened the hell out of them, but they continue to loosen as the adjustment points as you all know is the alternator and power steering points that are adjustable. Any input fellas?
Finally found the proper belt from a truck company for the alternator belt. We will see how it works.
THE ONLY BELTS THAT FIT PROPERLY ARE OEM. OEMMITSUBISHIPARTS.com. BTW price is ame like going to autozone except they fit perfect! 4d55 diesel fan belt MD064598. Power steering MB166386

They do not fit the same as the oem on the 4d55 . And they often times are more expensive than the oem ones unless you get them for $5 at rockauto.Quote:
