The location of the model and serial number plate can vary from machine to machine. Please consult your manufacturer’s manual for more details.

What are the delivery times for orders?

Rubber Tracks
What are the differences between Q Track and Terratrack Plus ranges?
Q Track is our standard rubber track offering, and TerraTrack Plus is a premium product with anti-vibration and anti-detracking technology.
How can I measure or identify the type of rubber track for my machine?
Just give us the make and model of your machine, and we will do the rest.
How can I prevent rubber tracks from detracking?
The most important factor in preventing detracking is to ensure that the track tension is correct at all times and the undercarriage is kept clean. You can, of course, solve the problem by buying TerraTrack Plus.
Can I easily convert my excavator from steel tracks to rubber tracks?
This is possible, but it depends on the make and model of your machine. Call our expert team of advisors to find out more.
Rubber Pads
What is the average lifespan of a rubber pad?
It is purely down to application. Used correctly on a paved surface, our rubber pads will last a long time, up to 36 months. However, used in the wrong environment, you could badly damage a set of rubber pads in a matter of weeks.
Do I need to fit rubber pads on every steel shoe or can I use them otherwise?
Rubber pads are designed to be fitted to every shoe on the machine. If you use only a half set, the ride will be very bumpy when tracking, and we cannot offer any warranty unless a full set is purchased and fitted.
Hydraulic Drives & Pumps
If I replace only one travel motor, will it have the same speed as the other?
In most cases, the speed will be identical. In cases where we know the speed will be different, we will offer two matched drives.
Are your travel motors delivered pre-filled with oil, or do I need to fill them after installation?
Our final drives are not filled with oil when delivered. You must follow the provided installation guide when filling with oil, and the level must be checked before use.
What type of oil should I use in your travel motors?
We recommend using 80W/90 oil in your final drive.
Can hydraulic swing motors be repaired?
Yes, hydraulic swing motors can often be repaired by replacing damaged parts or performing other maintenance tasks. However, it’s important to work with a qualified technician to ensure the repair is done correctly. Astrak does not currently offer this service.
Identifying Worn Components
How do I identify a worn idler?
Most commonly, the bearings would have collapsed, and the idler will be making a loud metal-on-metal noise.
How do I identify a worn roller?
Most commonly, the bearings would have collapsed, and the roller will be making a loud metal-on-metal noise.
How do I identify a worn sprocket?
The teeth should be sharp, pointed, and uniform in shape around the circumference of the sprocket.
Undercarriage Parts
What grease should I use with track adjusters?
Any kind of general-purpose lithium grease is suitable for use with our track adjusters.
What is a grouser and how do I measure it?
A grouser is the tread part of a steel track shoe. The height of the grouser should be measured using a depth gauge from the top of the grouser to the upper side of the base of the shoe.
Should I replace all my rollers at the same time?
In an ideal world, yes; this ensures even wear across all new rollers. If a customer does not want to order a full set, the next best option would be a half set. In this case, all the new rollers should be fitted on one side of the machine and the best of the worn rollers on the other side.
Is the tensioner included with the idlers?
No. At Astrak, when we refer to an idler, we are talking about the wheel, shaft, bearings, and side arms only.
Do I need new bolts with my steel shoes/sprockets/rollers/idlers?
We recommend that you always replace track bolts and nuts and undercarriage hardware when you replace the related parts. When a bolt is loosened, it takes on average 50% more torque than it was originally tightened to, which weakens the bolt.
How do I bend the retaining pin for quick attach pins?
The retaining pin should be bent around using a small hammer or similar. Do not use a form of heat to bend the retaining pin as this will weaken the pin.
