The Perfect Engine Rebuild Kit
Working on an engine is an inexpensive way of doing maintenance and a quick tune-up. Rather than go to shops looking for all the different bits and pieces you will need, manufacturers have gone through the trouble of packaging all the parts in one purchase for you to perform an engine rebuild. If you don't know your way around, buying one can be as complicated as working on the engine itself. Here are some guidelines to help you pick the perfect kit.
Know your purpose
Figure out first what you want to do with your engine. Ask yourself some questions. What are the worn-out parts you need to replace? Do you need to tinker with the whole engine, or are only the pistons in need of attention? Do you want to make your engine more powerful? Is the engine even worth rebuilding, or is a complete replacement better? This will not only help you pick out the right kit, but also help in setting a goal for yourself with the whole repair.
Engines come in different shapes and sizes. For example, bores can be wider or narrower; camshafts can be longer or shorter compared to others. Measure all the dimensions you can find. Count also the number of parts you will need. Only a fool would buy a kit for a 4-cylinder if the engine is a 6-cylinder. These are just some of the few things you need to count before buying a set. With all these numbers in hand, refer to the supplier's catalogue to see if they have the right kit for you.
Get only what you need
By this time, you should've already set a plan for yourself as to what you want to do with your engine. This will help you in picking the exact contents your kit will need. Manufactures know that not everyone needs a complete engine rebuild. Some just want to work on their pistons, while others would only want to tinker only the frame itself. Aside from the basic rebuild set, there are also high performance kits available for those who want to get more power out of the engine.
Overview of an Engine Rebuild
Working on an engine is a very tricky and complicated process. There are plenty of vital parts and technical information you have to take note off. Doing a repair at your personal shop is not recommended, unless you are a very experienced mechanic. This guide will give you a very general overview of the process to guide you. Consult other resources for an in-depth guide.
Difficulty level: Hard
- Soap and water
- Engine stand
- Complete wrench and socket set
- Engine oil
- Oil pump primer
- Assembly lube
- Plugs and sealers
- Engine rebuild kit
Step 1: Engines are very sensitive to dirt so it is important to clean your work area. Give your tables and floors a wash. Your tools should be clean as well.
Step 2: Drain the oil first. Overhaul and disassemble your engine. Wash all the parts too with soap and water. Arrange them in based on how they are assembled. Rub oil on the bores and cylinder walls.
Step 3: Return all freeze, cam and galley plugs.
Step 4: Insert the cylinder sleeves, and then match the pistons the cylinders. Check the user's manual to get the right measurements of each piston to the cylinder. Install the piston rings after. Finish by placing the pistons inside.
Step 5: Turn the engine upside-down on the engine block, install the camshaft and bearings. Use lubrication to make things easier.
Step 6: Replace the crankshaft next along with its caps and bolts to set the torque. Remember to check clearance of the crankshaft with the engine.
Step 7: Install all the timing gears, chains, and belts.
Step 8: Place the rod cap and secure with rod nuts.
Step 9: Turn the engine right side up and install the head gaskets, cylinder heads, torque heads, and all the other valves.
Step 10: Prime the oil pump. Next, prime the engine with a drill motor
Because of the complexity of the process, a thorough rebuild will take days to complete.
- Label all the parts to help you with reinstallation. You can also record a video of yourself doing the disassembly.
- Don't hesitate to let an expert do the rebuild for you.
- Have lots of patience, and you'll earn an improved engine
