Troubleshooting & FAQ

Which Volvo Penta models use this bushing?

This bushing fits AQ80, AQ100, AQ100B, AQ200, AQ250, AQ270, AQ275, AQ275A, AQ280 (all variants), AQ285A, and SP-A/MT drives. Always verify your original part number (826341 or 876278) before ordering.

How do I know when these bushings need replacement?

Common signs include difficulty shifting, gear slippage, unusual noise during shift engagement, or visible wear/cracking on the existing bushings during routine maintenance. Replace bushings as a pair to maintain balanced operation.

Can I install these without removing the entire outdrive?

In most cases, outdrive removal is required for safe access to the shift fork assembly. Attempting installation without proper disassembly may result in incomplete seating or component damage. Consult your service manual for specific procedures.

Are these bushings sold individually or as a pair?

This listing includes one pair of bushings, equivalent to Volvo Penta part number 876278, which is the standard replacement quantity for one shift fork assembly.

What is the difference between 826341 and 876278?

Both part numbers are cross-referenced by Volvo Penta for the same fork bushing application. 876278 typically refers to the paired kit, while 826341 may have been an earlier reference. Both are interchangeable for the models listed.

Do I need any special tools for installation?

Standard marine mechanic tools are sufficient. You may need a press or drift for seating bushings, depending on fit tolerance. Always follow torque specifications and alignment procedures outlined in your Volvo Penta service manual.
