This video demonstrates the purpose of the Manual Trans MT Belt Guide (Subaru part 13145AA021). It's an EXTREME test, for demonstration purposes. Turning the engine backwards with the cam "LOCKED" by a vise grip does not happen in real life. I've been driving an auto engine in a manual VW for 25 years with no belt guide. But my belt slipped last week so I studied the mechanism and found one way it can happen. It requires several bad conditions to happen at once. I had parked with the gearbox in a forward gear, using the engine to hold the (heavy) van from rolling backwards. Which turned the engine backwards very slowly. The parking brake was not set. This video shows how the Subaru Manual Trans MT Belt Guide 13145AA021 prevents belt slippage. There are other faults that can cause timing belt-slip, including failure to replace belts on time, idler roller bearing problems, water pump failure, over-rev, perhaps others. But the belt guide positively prevents slippage at the crank gear thus is a good item to have on your engine. At the end of the video I probed a Smallcar engine with a nail, confirming that Smallcar installs the Subaru Manual Trans MT Belt Guide to their conversion engines. And likely others do as well. If your engine has no belt guide, think carefully about which gear you choose when parking on a hill. If pointed downhill, use a forward gear (1st) . If pointed uphill, put it in reverse gear. =========== Tom Lengyel of Syncroshop, Oregon ========== He's a small Subaru-Vanagon shop said he's seen belt-slip four times over the years, all with no belt-guide. There could be other reasons the belt skipped, but he hasn't seen it on engines with the guide. =========== note from Richard Jones, engineer at RJES.com ========== In 20 years of working on this stuff, you’re the only person I have ever heard from who has had their belt slip due to not having a guide fitted. But I bet you’re not the only one. Richard Jones, R J Engineered Solutions Ltd www.rjes.com Quality Components for Subaru Powered VW Conversions
