Crusader v belt cross reference

[jon_allen]

Hello Gang,

Could someone possibly cross a couple of Crusader V belts to say Gates, Goodyear, or NAPA for me?
10258 which is a sea water pump belt and 6745 which drives the alt. Both are for a 1985 454 engine
350 hp. I have tried my sources but have come up with nothing.

Thank You
Jon Allen

I can get you some aftermarket numbers but it won't be til later tonight (EDT)...

Based on memory, the raw water pump belt is 17/32" wide and the circ pump/alt belt is 15/32 wide (at the top, without wear). you can measure the outer circumference of the belt, in inches - that becomes the last portion of the "part number" (three digits, without the decimal point). as an example, a 15/32 wide belt that measures 40.5" would be a #15405.

Tnx...i searched previous posts and found 17325 (17320) for the raw water pump and 15435 (15430) for the alternator. (yes, i fixed my typo driven by my meory fault)...

on the raw water pump, I found it was easier to remove the two mounting bolts, slide the belt on, and then reinstall the bolts and tighten them.

Hi Mark,
Thanks for the timely response. Which part numbers do I need ? The ones in parenthesis?



Thanks Again,

Jon Allen

Sorry for the lag...got pre-empted last night...the difference within a pair of part numbers given above is 1/2"...I think I use the longer ones...the parenthesized numbers were in another's post. Measure the OD of the belts you have and it should give you better insight...

I have a spare set of belts on the boat, but can not get to them now. Here is some onfo that may help, it is from another forum:

1988 11 Meter Trojan with 454 FWC engines: Gates - the raw water pump belt # is 9330 12.5mm x 850mm the alternator belt is #7470 9.5/10mm x 1210mm

Would these numbers be good for an 88 model 7.4 350?

You can measure OD without taking them off. Use a string or wire that does not stretch

Hi Gang,

Thanks to all of you. The belts are going on this morning.

hope I didn't steer you wrong...I peeked last night and saw an old set of 47" and 43.4" belts in my locker...then I pulled the hatch and remembered I swapped the motorola Alternators for the 10SI style...so the 47" is probably the correct one for the stock alternators...

Mike - they should be good for any MarkIV block using the v-belts....

Thanks Mark!
