Automotive Clutch Substitution Guidelines – Dos and Don’ts

Owning spent various many years in tech assist with a enterprise that sells guide transmissions, I have spoken with quite a few clients that have designed clutch set up blunders that price tag them dearly in conditions of time, revenue and stress. These strategies are based on my expertise with what is usually overlooked by a amateur that is installing a new clutch. This short article is NOT a substitute for a excellent car repair guide that is unique to the car or truck you are doing the job on! If any of these recommendations contradict the details in your assistance guide, observe the provider manual alternatively.

Suggestion # 1: Lubrication in all the correct destinations (and none of the mistaken spots!) – Put a gentle coat of grease on the pilot idea of the enter shaft and on the collar that the launch bearing slides on. Wipe a Very mild coat of oil on the input shaft splines to prevent rust. Be watchful to NOT get any grease on the flywheel, the clutch disc, or the force plate.

Suggestion # 2: Have the flywheel resurfaced, no matter how good it appears to be like. It only expenditures a few pounds, and the chance of having to take out the transmission again simply because of a chattering clutch is not worthy of the income you might save.

Idea # 3: Swap the pilot bearing or bushing. If you you should not have a particular pilot bearing puller software, some support manuals instruct you to eliminate the aged bearing by packing the cavity at the rear of the bearing with grease and applying a wooden dowel or old input shaft to push the old one particular out. I have observed that as a substitute of grease you can use perform dough, silly putty, or even some outdated bread, with equivalent or much better success and way considerably less mess!

Idea # 4: Don’t drive nearly anything! If the transmission won’t slide all the way up to the back of the bellhousing, do not draw the transmission up to the bellhousing by tightening the transmission to bellhousing bolts. I are unable to explain to you how lots of broken mounting ears and destroyed pilot bearings I have seen! If the transmission will not slide all the way in to the bellhousing, then the clutch disc is misaligned or the input shaft is not heading into the pilot bearing since the transmission is at an angle. Try this: Install or reattach the clutch linkage, and then have a helper depress the clutch pedal a little when you wiggle the transmission all around to get it aligned. When the clutch disc is introduced, it will go so that you can get the transmission aligned with the pilot bearing. I fought with a transmission for an hour a person time before I believed of this, and then it took about five seconds when I experienced a helper action on the clutch pedal!

Prior to tackling your initially clutch alternative, I really endorse looking through the entire technique in a repair guide or factory services manual. Even if you are a seasoned veteran, it doesn’t hurt to choose a seem at a company manual if you are changing a clutch in a auto you are not common with.
