Does anyone know the number of teeth on the flywheel for the 2001 VOLVO DPX500 8.2L. I am wanting to replace the starter with a High torque starter since mine is dragging and barely cranks. it has been that way since new ( I only have 89 hrs on the engines).

Ayuh,....... Pull the starter, 'n look at the bolt pattern,......
Straight across is a 12" flywheel, 153 tooth,.....
The staggered pattern is the 14", 168 tooth,....

Thanks a million, I have The staggered pattern starter Now I need to go find a starter.

Before you waste money on a starter make certain that all of the power and ground cables are clean and secure.

Ayuh,..... My advice is to go with a pmm style starter,..... 1/2 the weight, 'n twice the power of the ole style starters,....

I already done that, New 800 CCA battery tested, and clean connections Positives and Negatives on battery side and engine side, also timing has been moved a few degrees retarded and advanced.

What is "PMM" ? I looked for a Marine Mini starter with gear reduction but could not find one under $400.00 , I like the PowerMaster brand but they don't have Marine Starters,, I ordered ARCO Part #30470-ANEW OEM Quality Hi Torque, Permanent Magnet, Gear Reduction Starter. 1.7 KW for a couple hundreds and hopefully it will work otherwise I will have to step up the expense.

Ayuh,.... Permanent Magnet Motor,....

Thanks

Installed the new starter motor and to my surprise, cranked pretty good. but no start and after a bit of diagnostic found deffective Hi flow fuel pump. just ordered one.
