Automotive Clutch Replacement Tips – Dos and Don’ts

Acquiring used various years in tech assist with a organization that sells guide transmissions, I have spoken with lots of consumers that have built clutch set up blunders that charge them dearly in phrases of time, revenue and annoyance. These recommendations are primarily based on my expertise with what is often forgotten by a beginner that is setting up a new clutch. This posting is NOT a substitute for a very good vehicle mend guide that is distinct to the auto you are doing work on! If any of these tips contradict the information in your assistance manual, observe the company manual as a substitute.

Tip # 1: Lubrication in all the right places (and none of the wrong locations!) – Place a light-weight coat of grease on the pilot idea of the enter shaft and on the collar that the launch bearing slides on. Wipe a Extremely light coat of oil on the input shaft splines to reduce rust. Be careful to NOT get any grease on the flywheel, the clutch disc, or the stress plate.

Idea # 2: Have the flywheel resurfaced, no issue how great it appears to be like. It only expenses a couple of bucks, and the threat of having to take away the transmission yet again since of a chattering clutch is not worth the revenue you might preserve.

Suggestion # 3: Switch the pilot bearing or bushing. If you do not have a distinctive pilot bearing puller software, some services manuals instruct you to remove the old bearing by packing the cavity guiding the bearing with grease and making use of a picket dowel or outdated input shaft to drive the previous a single out. I have located that rather of grease you can use enjoy dough, foolish putty, or even some aged bread, with equal or superior outcomes and way considerably less mess!

Tip # 4: Do not power anything at all! If the transmission is not going to slide all the way up to the again of the bellhousing, do not draw the transmission up to the bellhousing by tightening the transmission to bellhousing bolts. I cannot notify you how numerous damaged mounting ears and damaged pilot bearings I have viewed! 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 going into the pilot bearing for the reason that the transmission is at an angle. Consider this: Set up or reattach the clutch linkage, and then have a helper depress the clutch pedal a little although you wiggle the transmission all over to get it aligned. When the clutch disc is produced, it will go so that you can get the transmission aligned with the pilot bearing. I fought with a transmission for an hour one time in advance of I assumed of this, and then it took about 5 seconds at the time I had a helper stage on the clutch pedal!

Just before tackling your initial clutch substitute, I hugely propose reading through the entire technique in a repair manual or manufacturing facility support handbook. Even if you are a seasoned veteran, it doesn’t harm to just take a search at a services manual if you are changing a clutch in a motor vehicle you are not acquainted with.
