MOT revisions From May 20, 2018, the Driver and Vehicle Standards Agency (DVSA) will be applying changes to the current MOT test and certificates. Full revisions have yet to be finalised as I write this, but we’re hoping to have a detailed report on the new MOT procedure for cars over three years old – and an update on cars over 40 years old – in the June issue, out on May 17. According to the DVSA, the rationale behind the revisions is to tighten up on emission system testing, especially with regard to diesel engines, and also to create three new categories to define necessary repairs. Advisories will continue to be part of the test. The three new categories to be listed on your MOT test sheet are: Dangerous A direct and immediate…

Whether your car is front- or rear-driven, with two-, four- or all-wheel drive, it requires shafts to transfer torque from the gearbox to the relevant road wheels, or axles. Each application may consist of one, or more, sections of either solid, or hollow, cylindrical tubing and a single shaft may consist of several connected sections. Despite being rather stressed components, they usually give little trouble, although regular inspections and the occasional renewal of deteriorated parts will lengthen their lives considerably. Differing formats Rear-, four- and all-wheel drive systems rely on a propshaft to deliver torque to the rear differential. The influences of suspension articulations are satisfied, most commonly, by a Hooke-type universal joint (UJ) that allows two shafts that are out of alignment to rotate together. Often, a sliding joint features as…

what goes wrong?

Under the new MOT test regime, worn transmission shaft bearings, joints or flexible couplings are classified as ‘Major’ or ‘Dangerous’ faults. However, you should be able to detect any problems before they become unsafe. Aside from being a balancing issue, propshaft vibrations tend to stem from a worn UJ or centre bearing. Grip the shaft either side of each UJ and rotate in an opposing direction; any movement within any of the UJ’s four bearings indicates excessive wear and the whole spider assembly must be renewed. Worn centre bearings or perished/split rubber joints will also need attention. Naturally, prevention is better than cure and, while most modern UJs do not require periodic greasing (by the lubricant being forced into the joint via a nipple with a grease gun), the sliding joint…

tales from the workshop

VAUXHALL ASTRA Timing belt time One common misconception is that the cost of changing a timing belt is pretty much the same for all vehicles. What people don’t consider is that the price reflects the complexity of the job, depending how much time is required. One of our customers was pleasantly surprised by how little we were going to charge for the timing belt replacement on a 2004 Vauxhall Astra 1.6. The book time on the job is less than an hour, thanks to easy access to the belt once the air filter housing has been removed. After the timing belt cover has been detached, the pulleys have clear markings on them and the belt change can be carried out without any awkward manoeuvres.
