It is pretty much inevitable that you will experience issues while trying to drive your G1 Yamaha Golf cart. Loss of power in your Yamaha G1 golf cart can be the result of a number of issues. A faulty clutch, a sloppily calibrated carburetor, or a worn-out drive belt can all contribute to this problem. Your Yamaha G1 golf cart might not be able to come to a complete stop and turn off if the wiring is faulty, the solenoid is stuck, or the pedal stop switch is stuck.
The severity of G1 Yamaha Golf Cart concern may vary. Some are easy enough to diagnose and correct with a few inexpensive parts and some basic mechanical know-how at home.
Common Problems with G1 Yamaha Golf Carts And Solutions At a Glimpse:
| Problem | Solution |
| Compression | Maintaining a certain compression |
| Frame rust | Cleaning the frame or replacing the frame |
| Oil Injector & Oil seals | Inspect the crankshaft for grease behind the primary clutch |
| Clutch issues | Remove the lid and clean it regularly |
| Drive belts and Old gas | Check regularly to ensure they are within tolerances |
| Fuel pumps | Rebuild it or clean it up |
The majority of the G1 carts are fairly old and see a lot of use, therefore the problems that arise typically relate to one of the cart’s component parts.
1. Compression
Worn rings of the piston or oil seals are the most likely culprits when compression drops.
Solution:
For optimal performance, compression should be about 100 psi, whereas after a complete rebuild, it should be between 120 and 130 psi. If you have a 1982 model, I’m afraid your engine has a lower compression rate of roughly 90-100psi and can’t keep up. Yamaha’s attempt to reduce emissions and noise levels began with the 1982 model year, but by 1983, the company had abandoned that direction after realizing the model’s performance had suffered as a result.
2. Frame rust
Rust in the frame, especially around the battery tray, is a persistent problem. Many folks don’t bother to replace the old tray after having it cut out.
Reduce the Frame rust:
There are a few different options for replacing the tray, however it will probably require some special fabrication. The project will require the use of new metal angles, metal sheets, a new hold bar, some cutting, welding, and painting. The swing arms and cross tubes also see a lot of use, but they rarely get washed, so they tend to accumulate a lot of dirt and filth. The same goes for repairing custom-made items.
3. Oil Injector & Oil seals
Oil Injector failures are not that common, but they happen. On the other hand, crankshaft oil seals tend to wear very quickly. Oil seals are a common culprit when a golf cart won’t start or operates poorly.
Resolving the Oil Injector Failure Issue:
Even though oil injector failure is uncommon, it can have a devastating effect on an engine. Seals that have worn out will result in decreased compression as well as poor performance. Have a look at the crankshaft for signs of grease or moisture behind the primary clutch. It’s likely that the seals will need to be replaced if this is the case.
4. Clutch issues
Issues with the clutch will reduce the vehicle’s speed and power. Grease and grime can build up on the primary clutch and prevent it from engaging.
Solution to the Clutch Issues:
The performance degradation can be greatly reduced by removing the lid and cleaning it on a regular basis. Remember to apply a very small amount of grease on the shaft; otherwise, it may fly out of the clutch housing. It’s common for the secondary clutches to break or “dish out” due to wear and tear. As a result, the cart may not be able to reach its top speed very quickly or may have no low-end power at all.
5. Issues with Drive belts and Old gas
Worn or broken drive belts can hinder acceleration and transmission. In reality, this fundamental aspect of maintaining a vehicle is often overlooked: replacing the old gas.
Fixing the Broken Drive Belts:
Belts should be checked and replaced on a regular basis to ensure they are within tolerances. Carts that have been sitting for an extended period of time may have stale gas. In a similar vein, the gas in the gas can from a long time ago might not be very good. Attempt a new plug and some fresh gas if the old one isn’t getting the job done on your golf cart. Be sure to top off the oil tank!
6. Issues with Fuel pumps
These carts have a high failure rate for their fuel pumps.
Solving the Fuel Pump Issue:
You can rebuild it or clean it up; read up on how to do that. You can get a brand new one for somewhere between $40 and $50. You can also rig up a petrol pump from a vehicle. If there is no fuel coming out of the carburetor, check the fuel pump and the fuel filter.
A Regular Check-Up Checklist to Avoid All Potential Issues:
- Lubricate the auxiliary clutch so it can be removed from its locked position and readily shifted up and down. You might also consider removing it, properly cleaning it, then reinstalling it.
- If you observe that the keys are broken or worn out, change the slider unit entirely.
- Replace the snap ring in the groove where it was likely to have fallen off. It’s a good idea to clean this area before repositioning the ring.
- Check that the drive chain would be neither too tight nor too loose. Adjust it to achieve the desired tension.
- Wipe the fan and cooler blades on the cylinder completely so that they can move freely.
- Change the crank sealing if it is broken or even slightly cracked, as this might allow oil to leak.
- Perform a compression test on the engine with a compression tester to confirm that it has the required compression.
- Wipe a congested or jammed muffler to ensure that it is fully clean and free of dust or dirt.
