2002 Damon Intruder 350. W22 chassis with 8.1 Chevy V8. I've been told this belt is the correct one, is it? Also, any additional info on how to remove/replace it as there is only access from under the engine.

Thank you.
( Eric, 01/19/2021 )
This is the correct belt for your W22. To replace, install a 3/8" drive ratchet into the belt tensioner and rotate the arm to release tension and slip the belt off. For installation, route the belt over all the pulleys expect the tensioner arm pulley. Using the 3/8" drive ratchet, relieve tension on the tensioner and slip the belt back over that pulley and slowly release the tension. Attached is a diagram of the belt routing:  ( Support )

We are buying a 2010 Newmar Canyon Star 3410 with the Workhorse 8.1L engine (sorry, I don't have the VIN yet). Do you offer "how to" videos for replacing parts on this motorhome engine to go with the purchased parts?

Thanks!

Instruction on how to install

( Judy smitherman, 09/14/2015 )

Judy,

In the pictures of this product it shows the belt routing, however, if you want detailed description on replacement you will want to download the Engine Service Manual for the appropriate year and model of your chassis. You can find those manuals by clicking here: Workhorse Service Manuals
